To determine the effectiveness of dynamic muscle training and relaxation training for chronic neck pain.
                Randomised controlled trial.
                Five occupational healthcare centres, Tampere, Finland.
                393 female office workers (mean age 45 years) with chronic non-specific neck pain randomly assigned to 12 weeks of dynamic muscle training (n = 135) or relaxation training (n = 128), plus one week of reinforcement training six months after baseline; or ordinary activity (control group; n = 130).
                Change in intensity of neck pain at three, six, and 12 months.
                No significant difference was found in neck pain between the groups at follow up. However, the range of motion for cervical rotation and lateral flexion increased more in the training groups than in the control group.
                Dynamic muscle training and relaxation training do not lead to better improvements in neck pain compared with ordinary activity. To determine whether a home-based pedometer-driven walking program with arthritis self-management education (Walk +) would increase physical activity, muscle strength, and functional performance in older adults with osteoarthritis (OA) of the knee as opposed to arthritis self-management education alone (EDU).
                A randomized two-by-three (group-by-time) design with participants assigned to Walk + (n = 17, mean age +/- standard deviation = 69.6 +/- 6.7) or EDU (n = 17, age = 70.8 +/- 4.7).
                Community located in the Baltimore-Washington area.
                Thirty-four community-dwelling adults, aged 60 and older with symptomatic knee OA and self-reported functional impairment.
                Both groups received 12 hours of the Arthritis Self-Management program over 12 weeks and were followed for an additional 12 weeks. In addition, the Walk + group received individualized instruction in the use of a pedometer, with the goal of increasing their step count by 30% of their baseline step count.
                The outcome measures were physical activity (daily step counts and total activity vector magnitude as measured by a pedometer and Tritrac-R3D accelerometer), quadriceps femoris strength (isometric peak torque), and functional performance tasks (100-foot walk-turn-walk, timed stair climb, timed chair rise, and pain status).
                Daily steps walked showed a significant group-by-time interaction (P =.04) after controlling for age. From baseline to completion of training, a 23% increase in daily steps occurred in the Walk + group and a 15% decrease in the EDU group. Although steps increased in the Walk + group, total activity vector magnitude was maintained, suggesting a more efficient gait. The Walk + group became quicker than the EDU group in the normal-pace walk-turn-walk (P =.04). An isometric strength gain of 21% postintervention was seen in the Walk + group, compared with a loss of 3.5% in the EDU group.
                In older adults with symptomatic knee OA, Walk + appears to increase walking, with improvements in muscle strength and walking performance. The use of a home-based pedometer-driven program to increase physical activity, strength, and function in this population warrants further research. To establish the relative effectiveness and cost of providing a home-based exercise programme versus home-based exercise supplemented with an 8-week class-based exercise programme.
                The trial was a pragmatic, single-blind randomised clinical trial accompanied by a full economic evaluation.
                Patients were randomly allocated to either home-based exercise or home exercise supplemented with class exercise programmes.
                A total of 214 patients, meeting the American College of Rheumatology's classification of knee osteoarthritis, were selected from referrals from the primary and secondary care settings.
                Both groups were given a home exercise programme aimed at increasing lower limb strength, and endurance, and improving balance. The supplemented group also attended 8 weeks of twice-weekly knee classes run by a physiotherapist. Classes represented typical knee class provision in the UK.
                Assessments of locomotor function, using a timed score of three locomotor activities, walking pain and self-reported disability with the Western Ontario and McMaster's Universities osteoarthritis index (WOMAC) were made. General health, lower limb strength, range of movement and compliance with exercise were also measured. Patients were assessed before and after treatment, and also at 6- and 12-month follow-ups. The economic evaluation looked at health service resource use and assessed cost-effectiveness by relating differential costs to differences in quality-adjusted life-years (QALYs) based on patients' responses to the EuroQol-5 Dimensions. Data were obtained at baseline, 1 month, 6 months and 12 months through face-to-face interviews and, where appropriate, examination of hospital medical records.
                Patients from the supplemented group demonstrated significantly greater improvement in locomotor function and decrease in pain while walking at all follow-ups. The supplemented group also demonstrated smaller but significant improvements in balance, strength, WOMAC score, and the physical function and pain dimensions of the Short Form-36. However, not all of these improvements were maintained over the 12-month follow-up period. There was no evidence that compliance with the home exercise programme was different or that total costs or mean QALY gains were significantly different between the groups. However, costs were slightly lower and QALY gains slightly higher in the group with the supplementary class-based programme. The economic evaluation suggests that supplemented programmes are likely to be considered cost-effective, although there is uncertainty around this estimate, with approximately 30--35% probability that the intervention would not be cost-effective.
                The supplementation of a home-based exercise programme with a class-based exercise programme led to superior improvement in the supplemented group. These differential improvements were still evident at review 12 months after treatment had ceased. The additional cost of the supplemented group was offset by reductions in resource use elsewhere in the system. Compliance with the home exercise programme did not differ between the groups. Based on this evidence, the supplementation of a home-based exercise programme with an 8-week class-based exercise programme can be confidently expected to produce small improvements in locomotor function and clinically important reductions in pain. It is recommended that future research investigates methods of increasing compliance with home exercise programmes and evaluates the impact of these interventions in the primary care setting, where most patients with knee osteoarthritis are managed. Chronic knee pain is a major cause of disability and health care expenditure, but there are concerns about efficacy, cost, and side effects associated with usual primary care. Conservative rehabilitation may offer a safe, effective, affordable alternative. We compared the effectiveness of a rehabilitation program integrating exercise, self-management, and active coping strategies (Enabling Self-management and Coping with Arthritic Knee Pain through Exercise [ESCAPE-knee pain]) with usual primary care in improving functioning in persons with chronic knee pain.
                We conducted a single-blind, pragmatic, cluster randomized controlled trial. Participants age >/=50 years, reporting knee pain for >6 months, were recruited from 54 inner-city primary care practices. Primary care practices were randomized to continued usual primary care (i.e., whatever intervention a participant's primary care physician deemed appropriate), usual primary care plus the rehabilitation program delivered to individual participants, or usual primary care plus the rehabilitation program delivered to groups of 8 participants. The primary outcome was self-reported functioning (Western Ontario and McMaster Universities Osteoarthritis Index physical functioning [WOMAC-func]) 6 months after completing rehabilitation.
                A total of 418 participants were recruited; 76 (18%) withdrew, only 5 (1%) due to adverse events. Rehabilitated participants had better functioning than participants continuing usual primary care (-3.33 difference in WOMAC-func score; 95% confidence interval [95% CI] -5.88, -0.78; P = 0.01). Improvements were similar whether participants received individual rehabilitation (-3.53; 95% CI -6.52, -0.55) or group rehabilitation (-3.16; 95% CI -6.55, -0.12).
                ESCAPE-knee pain provides a safe, relatively brief intervention for chronic knee pain that is equally effective whether delivered to individuals or groups of participants. This paper is a report of a study to assess the effect of an adapted arthritis self-management programme with an added focus on exercise practice among osteoarthritic knee sufferers.
                Osteoarthritis of the knee is a major source of loss of function in older people. Previous studies have found self-management programmes to be effective in increasing arthritis self-efficacy and in mastery of self-management practice.
                A randomized control trial was carried out from December 2002 to May 2003 and 120 participants (65.9%, including 67 in intervention group and 53 in control group) completed the 16-week postintervention assessments. Outcome measures included arthritis self-efficacy, use of self-management techniques, pain intensity and daily activity.
                At 16 weeks, there was a 'statistically' significant improvement in the arthritis self-efficacy level (P <or= 0.001), in most of the self-management skills, i.e. use of cold and hot compresses, in two of three joint protective practices (P <or= 0.001; P = 0.01), an increase in the duration of light exercise practice (P <or= 0.001), reduction of current arthritis pain (P <or= 0.001) and in the ability to perform daily activities (P <or= 0.001) among the intervention group but not for the control group (P-range from 0.04 to 0.95). One joint protective practice showed a statistically significant increase in both groups (P <or= 0.001).
                Our findings add to evidence showing short-term beneficial effects of self-efficacy theory in education programmes. Self-efficacy theory has great potential for empowering sufferers of chronic conditions to live with their illness. People with osteoarthritis (OA) of the knee experience pain and deconditioning that lead to disability. This study challenged the clinical belief that repetitive lower extremity exercise is not indicated in persons with knee OA. The effects of high-intensity and low-intensity stationary cycling on functional status, gait, overall and acute pain, and aerobic capacity were examined.
                Thirty-nine adults (71+/-6.9 years old) with complaints of knee pain and diagnosis of OA were randomized to either a high-intensity (70% heart rate reserve [HRR]) or low-intensity (40% HRR) exercise group for 10 weeks of stationary cycling. Participants cycled for 25 minutes, 3 times per week. Before and after the exercise intervention they completed the Arthritis Impact Measurement Scale 2 for overall pain assessment, underwent timed chair rise, 6-minute walk test, gait, and graded exercise treadmill tests. Acute pain was reported daily with a visual analog scale and the Western Ontario and McMaster Universities Osteoarthritis Index scale.
                Analysis of variance revealed that participants in both groups significantly improved in the timed chair rise, in the 6-minute walk test, in the range of walking speeds, in the amount of overall pain relief, and in aerobic capacity. No differences between groups were found. Daily pain reports suggested that cycling did not increase acute pain in either group.
                Cycling may be considered as an alternative exercise modality for patients with knee OA. Low-intensity cycling was as effective as high-intensity cycling in improving function and gait, decreasing pain, and increasing aerobic capacity. A randomized comparative study with single-blind outcome assessments.
                To compare the efficacy of a multimodal treatment emphasizing proprioceptive training (ACTIVE) with activated home exercises (HOME) and recommendation of exercise (CONTROL) in patients with nonspecific chronic neck pain.
                The efficacy of active exercises and passive physiotherapy for neck trouble has been somewhat disappointing in the previous few studies.
                Seventy-six patients (22 men, 54 women) with chronic, nonspecific neck pain participated. Sixty-two participated the 1-year follow-up. Subjective pain and disability, cervical ranges of motion, and pressure pain threshold in the shoulder region were measured at baseline, at 3 months, and at 12 months. The ACTIVE treatment consisted of 24 sessions of proprioceptive exercises, relaxation, and behavioral support. The HOME regimen included a neck lecture and two sessions of practical training for home exercises and instructions for maintaining a diary of progress. The CONTROL treatment included a lecture regarding care of the neck with a recommendation to exercise.
                The average self-experienced total benefit was highest in the ACTIVE group, and the HOME group rated over the CONTROL group (P < 0.001). Differences between the groups in favor of the ACTIVE treatment were recorded in reduction of neck symptoms and improvements in general health and self-experienced working ability (P < 0.01-0.03). Changes in measures of mobility and pressure pain threshold were minor.
                Regarding self-experienced benefit, the multimodal treatment was more efficacious than activated home exercises that were clearly more efficacious than just advising. No major differences were noted in objective measurements of cervical function between the groups, but the content validity of these assessments in chronic neck trouble can be questioned. This study examined the impact of a home-based self-management intervention for housebound older adults with arthritis on the adoption of health behaviors. The moderating role of socio-demographic, psychological, and physical characteristics in the process of behavior change was also investigated.
                Participants were 113 older adult women (n = 102) and men (n = 11) with osteoarthritis (OA) or rheumatoid arthritis (RA) who were randomly assigned to experimental (n = 68) or wait list control (n = 45) groups. Participants were interviewed using standardized questionnaires at baseline, pre-intervention, and post-intervention.
                Adjusted multilevel modeling analyses indicated that from pre to post intervention, experimental participants significantly increased their weekly frequency of exercise and relaxation activities. Socioeconomic status and depression played a moderating role in this change for exercise with larger effects occurring among more privileged, non-depressed participants.
                We conclude that a self-management intervention can successfully improve involvement in exercise and relaxation among housebound older adults with arthritis. Twelve forms of Sun-style tai chi exercise have been developed specifically to reduce the symptoms and improve the physical functioning of arthritic patients, and this randomized study examined the changes in symptoms and physical characteristics in older women with osteoarthritis (OA) at the completion of a 12-week tai chi exercise program.
                Seventy-two patients with OA were randomly assigned into 2 groups. Due to a 41% overall dropout rate, 22 experimental subjects and 21 controls completed pre- and post-test measures over a 12 week interval. Outcome variables were physical symptoms and fitness, body mass index, cardiovascular functioning, and perceived difficulties in physical functioning. The independent t test was used to examine group differences.
                The homogeneity test confirmed that there were no significant group differences in demographic data and pretest measures. Mean comparisons of the change scores revealed that the experimental group perceived significantly less pain (t = -2.19, p = 0.034) and stiffness (t = -2.13, p = 0.039) in their joints, and reported fewer perceived difficulties in physical functioning (t = -2.81, p = 0.008), while the control group showed no change or even deterioration in physical functioning after 12 weeks. In the physical fitness test, there were significant improvements in balance (t = 3.34, p = 0.002) and abdominal muscle strength (t = 2.74, p = 0.009) for the tai chi exercise group. No significant group differences were found in flexibility and upper-body or knee muscle strength in the post-test scores.
                Older women with OA were able to safely perform the 12 forms of Sun-style tai chi exercise for 12 weeks, and this was effective in improving their arthritic symptoms, balance, and physical functioning. A longitudinal study with a larger sample size is now needed to confirm the potential use of tai chi exercise in arthritis management. An intervention designed to enhance preaction self-efficacy beliefs (i.e., beliefs about ability to initiate behavior despite anticipated barriers during the initiation period) was tested in patients with spondylosis in relation to initiation of exercises recommended by a consultant in orthopedic rehabilitation. Sixty patients (age 28-83 years; 44% men) with spondylosis who had not previously performed exercises recommended for degenerative spine diseases were randomly assigned to a control (education session) or intervention group. Three weeks later, intervention patients performed recommended exercises more frequently than controls. Regression analysis for all patients showed that preintervention, preaction self-efficacy predicted exercise. Age and preintervention self-efficacy moderated the intervention effects. Among older patients, only those with weak preintervention, preaction self-efficacy beliefs benefited from the intervention, whereas among younger patients, only those with strong preintervention, preaction self-efficacy beliefs benefited from the intervention. A prospective, randomized, controlled trial with a stratification block design in which a Mensendieck exercise program was compared with the experience of a control group.
                To evaluate the effect of a Mensendieck program on the incidence of recurrent episodes of low back pain in patients with a history of the condition who currently are working.
                One episode of low back pain increases the risk of further episodes of the condition. The Mensendieck approach combines education and exercise. This approach has been used for many years in Scandinavia and the Netherlands. However, the effects on low back pain have not been evaluated previously in a randomized, controlled trial.
                A total of 77 men and women, mean age 39.6 years (range, 21.2-49.8 years), who had finished treatment for a low back pain episode, were stratified according to incidence of low back pain episodes and symptoms of sciatica over the preceding 3 years. The patients were assigned at random to either the Mensendieck program or a control group. The Mensendieck group received 20 group sessions of exercises and ergonomic education in 13 weeks. At 5- and 12-month follow-up examinations, the patients were assessed for recurrence of low back pain, days of sick leave, low back pain, and functional scores.
                After 12 months, there was a significant reduction in recurrent low back pain episodes in the Mensendieck group compared with the control group (P < 0.05). There was a trend toward fewer days of sick leave because of low back pain in the Mensendieck group, but no significant differences between the groups. There was reduction in pain and improvement in function in both groups, with no significant differences between the groups.
                A secondary prophylaxis Mensendieck exercise program of 20 group sessions significantly reduced the incidence of low back pain recurrences in a population with history of the condition. However, there were no differences between the groups with regard to days of sick leave, low back pain, and function. The long-term outcome results of inpatient and outpatient treatment of low back pain (LBP) were studied in 476 subjects (aged 35-54, 63% men) randomly assigned to three study groups: inpatients (n = 157), outpatients (n = 159), and controls (n = 160). The study included changes in the severity of low back pain, grade and disability, compliance with self-care, data on disability pensions, and days of sickness allowance during a 2.5-year follow-up period. These variables were used as outcome criteria. Pain and disability had decreased significantly in the two treated groups up to the 3-month follow-up. LBP was still a little slighter in the inpatients at the 1.5-year and 22-month follow-ups, but there were no significant differences between the groups in disability caused by LBP. The refresher programme carried out 1.5 years after the first one did not bring about as clear short-term improvement in pain and disability as the first treatment. During the whole 2.5-year follow-up compliance with self-care was better in the two treated groups, especially in the inpatients. Days of sickness allowance had increased somewhat more in the controls than in the inpatients during the follow-up. No differences between the groups were found in the number of disability pensions granted. We conducted a pilot study of a nurse-run telephone self-management programme for elderly people with osteoarthritis (OA). Thirty-two subjects, aged 60 years or more, with a diagnosis of OA were recruited from two hospital rheumatology clinics and were randomized to a control or intervention group. The intervention group received six weekly mailings of OA health education modules, a relaxation audio-tape and six weekly 45 min follow-up telephone self-management sessions. There was a 100% compliance rate in the intervention group, and all subjects completed baseline and three-month interviews; one subject in each group was lost to six-month follow-up. There were no significant differences in self-management between the control and intervention groups. However, at three months there were improvements in the intervention group (relative to baseline) on some outcome measures. The results suggest that the telephone may be a useful tool for reinforcing health-promoting activities for patients. Quadriceps weakness is a risk factor for incident knee osteoarthritis (OA). We describe a randomized controlled trial of effects of lower-extremity strength training on incidence and progression of knee OA.
                A total of 221 older adults (mean age 69 years) were stratified by sex, presence of radiographic knee OA, and severity of knee pain, and were randomized to strength training (ST) or range-of-motion (ROM) exercises. Subjects exercised 3 times per week (twice at a fitness facility, once at home) for 12 weeks, followed by transition to home-based exercise after 12 months. Assessments of isokinetic lower-extremity strength and highly standardized knee radiographs were obtained at baseline and 30 months.
                Subjects in both groups lost lower-extremity strength over 30 months; however, the rate of loss was slower with ST than with ROM. Compared with ROM, ST decreased the mean rate of joint space narrowing (JSN) in osteoarthritic knees by 26% (P = not significant). However, the difference between ST and ROM groups with respect to frequency of knee OA progression in JSN consensus ratings was marginally significant (18% versus 28%; P = 0.094). In knees that were radiographically normal at baseline, JSN >0.50 mm was more common in ST than in ROM (34% versus 19%; P = 0.038). Incident JSN was unrelated to exercise adherence or changes in quadriceps strength or knee pain.
                The ST group retained more strength and exhibited less frequent progressive JSN over 30 months than the ROM group. The increase in incident JSN >0.50 mm in ST is unexplained and requires confirmation. This study examined, in a group of older patients, (a) the effectiveness of an invitation to participate in a program providing individualized physical activity advice in a primary care setting and (b) the changes in self-reported physical activity and symptoms in patients with osteoarthritis (OA).
                Healthy, sedentary community-dwelling men and women aged 60 years or more were invited to participate. Following random allocation, the intervention group received individualized physical activity advice at baseline and at 3, 6, and 12 months followup.
                Of the 299 people who satisfied the study's inclusion criteria, a subgroup of 69 people reported pain and stiffness of the hip or knee at baseline. These patients reported increases in frequency and time of walking and vigorous exercise (all P < 0.001), with no change to OA symptom scores (pain and stiffness), and a small decline in physical functioning was reported at 12 months followup in the control group only (P = 0.027). At the 12-month followup more intervention participants than control participants (P = 0.013) reported a greater intention to exercise.
                An offer of primary care-based physical activity advice, with an emphasis on the benefits for general health (rather than "treatment" for OA), will attract individuals with OA symptoms. Although the present study was unable to demonstrate intervention-control group differences for the majority of outcomes, intention to exercise did appear to be positively influenced. This study investigated factors related to an initial exercise experience to explain exercise maintenance in 120 adults with rheumatoid arthritis or osteoarthritis. Integral secondary analysis was used to incorporate data from a prospective, controlled trial of exercise (Minor et al.: Arthritis Rheum 32:1396, 1989) with data collected at 18 months follow-up. The dependent variable was self-directed exercise (min/wk) reported at 3, 9, and 18 or more months after exercise class participation. Predictor variables included physical, psychosocial, disease, and programmatic factors. The all possible regressions search procedure resulted in three explanatory models (p = .0001). At 3 months the model (R2 = .45) included initial aerobic capacity, depression, and anxiety; and changes in depression and social activity. The 9-month model (R2 = .35) consisted of initial anxiety and physical activity, change in depression, support of friends for exercise, and exercise behavior at prior assessment. At 18 or more months (R2 = .42), model variables were initial aerobic capacity, change in pain, and exercise behavior at the two prior assessments. Neither disease nor program factors appeared as significant. This limited study indicates that factors associated with exercise behavior in this sample are similar to those in the general population; explanatory factors change over time, and changes ascribed to a trial behavior may influence subsequent decision making. Determination of the mode of action of new exercise techniques in different back pain populations is lacking. The effectiveness of supplementing an exercise programme with stabilisation exercises concerning physiological and functional parameters in non-specific back pain patients is unknown.
                Randomised controlled trial, comparing a general trunk muscle endurance exercise approach enhanced with specific muscle stabilisation exercises (S&G group) with a general exercise approach only (G group). 55 patients with recurrent back pain were randomised in S&G group (n=29) and G group (n=26). Both groups received an 8-week exercise intervention and written advice. Paraspinal muscle strength and electromyographic fatigue of the erector spinae and multifidus were measured. Additionally, 3 functional speed tests were assessed. Outcomes were collected pre- and post-intervention.
                No differences were detected for any of the paraspinal fatigue characteristics either within or between groups, apart from a significant decrease in normalised median frequency slope of the erector spinae for the G group. Paraspinal muscle strength and all functional tests have demonstrated significant within-group improvements for both groups, without any between-group differences.
                An 8-week stabilisation exercise-enhanced approach presented equal benefits to a general endurance-based exercise programme for patients with recurrent non-specific back pain. A slightly steeper slope for the erector spinae in the G group was the only electromyographic fatigue alteration noted. Concomitant strength improvement probably reflects neural input changes rather than histochemical muscle changes. Physical exercise alone and not the exercise type was the key determinant for improvement in this patient group. Different types of integrated management programmes have lately been introduced in the treatment of Whiplash Associated Disorders (WAD). In this study regular primary care physiotherapy and physiotherapy management with integrated components of cognitive-behavioural origin was compared in an experimental group study. The predictive value of self-efficacy was also addressed. In all thirty-three patients with chronic WAD were included in the trial. Results revealed no significant differences between groups in self-ratings of disability or pain intensity. However, among the self-reported benefits of treatment, patients in the experimental group reported significantly less pain than did the comparison group. At three months follow-up the experimental group also reported better performance of daily activities. Between group differences in the coping repertoire were found at pre-, post-and three-month follow-up. Generally, patients with high self-efficacy reported less use of 'maladaptive' and passive coping style than less self-efficient subjects at all times. In conclusion cognitive behavioural components can be useful in physiotherapy treatment for patients with chronic WAD, but their contributions are not yet fully understood. Self-efficacy is related to patients' use of different coping styles. Positive long-term outcomes in WAD-patients could therefore be improved by boosting self-efficacy and by teaching patients to use active, adaptive coping strategies. Practice guidelines recommend various types of exercise and manipulative therapy for chronic back pain but there have been few head-to-head comparisons of these interventions. We conducted a randomized controlled trial to compare effects of general exercise, motor control exercise and manipulative therapy on function and perceived effect of intervention in patients with chronic back pain. Two hundred and forty adults with non-specific low back pain 3months were allocated to groups that received 8weeks of general exercise, motor control exercise or spinal manipulative therapy. General exercise included strengthening, stretching and aerobic exercises. Motor control exercise involved retraining specific trunk muscles using ultrasound feedback. Spinal manipulative therapy included joint mobilization and manipulation. Primary outcomes were patient-specific function (PSFS, 3-30) and global perceived effect (GPE, -5 to 5) at 8weeks. These outcomes were also measured at 6 and 12months. Follow-up was 93% at 8weeks and 88% at 6 and 12months. The motor control exercise group had slightly better outcomes than the general exercise group at 8weeks (between-group difference: PSFS 2.9, 95% CI: 0.9-4.8; GPE 1.7, 95% CI: 0.9-2.4), as did the spinal manipulative therapy group (PSFS 2.3, 95% CI: 0.4-4.2; GPE 1.2, 95% CI: 0.4-2.0). The groups had similar outcomes at 6 and 12months. Motor control exercise and spinal manipulative therapy produce slightly better short-term function and perceptions of effect than general exercise, but not better medium or long-term effects, in patients with chronic non-specific back pain. This study compares the outcomes of an individually tailored behavioral medicine intervention (experimental) with physical exercise therapy (control). The experimental intervention was systematically individualized according to each participant's behavioral treatment goals and functional behavioral analyses. One hundred twenty-two patients seeking care at 3 primary health care clinics because of musculoskeletal pain were randomized. Ninety-seven completed the trial. Data were collected at baseline, immediately after treatment, and at a 3-month follow-up. Analyses of data from completers, as well as intention-to-treat analyses, showed that the experimental group experienced lower levels of disability (P = .01), lower maximum pain intensity (P = .02), higher levels of pain control (P = .001), and lower fear of movement (P = .022) as a result of treatment condition. Self-efficacy (P = .0001) and physical performance (P = .0001) increased over time for both groups. Participants in the experimental group generally reported more positive effects after treatment. Treatment fidelity was maintained during the course of the study. Activity can be resumed and pain might be managed by the patients themselves if treatment incorporates the biopsychosocial explanatory model of pain and strategies are tailored according to individual's priorities of everyday life activities and empirically derived determinants of pain-related disability.
                This study shows that the biomedical and the psychosocial perspectives of the experiences and consequences of pain complement rather than contradict each other. Primary health care patients with persistent musculoskeletal pain benefit more from a systematic tailoring of treatments according to biopsychosocial factors than from a physically based exercise intervention. The objective of this study was to determine whether the Arthritis Self-Management Programme (ASMP) improves perceptions of control, health behaviours and health status, and changes use of health care resources. The design was a pragmatic randomized controlled study; participants were allocated to ASMP (Intervention Group) or a 4-month waiting-list Control Group. The Intervention Group completed a 12-month follow-up. In total, 544 people with arthritis were recruited from the community--311 in the Intervention Group and 233 in the Control Group. Main outcome measures included: arthritis self-efficacy, health behaviours (exercise, cognitive symptom management, diet and relaxation) and health status (pain, fatigue, anxiety, depression and positive affect). At 4 months follow-up, the ASMP had a significant effect on arthritis self-efficacy for other symptoms and pain subscales. Performance of a range of health behaviours (cognitive symptom management, communication with physicians, dietary habit, exercise and relaxation) was significantly greater among the Intervention Group. The Intervention Group were significantly less depressed and had greater positive mood. In addition, trends towards decreases on fatigue and anxiety were noted. Physical functioning, pain and GP visits remained stable at 4 months. A similar pattern of findings was found at 12 months follow-up for the Intervention Group. Furthermore, a significant improvement was found on pain and visits to GPs had decreased. Apart from a small improvement on physical functioning among the Intervention Group participants with osteoarthritis 12 months, all effects were independent of the type of arthritis. The findings suggest that the ASMP is effective in promoting improvements in perception of control, health behaviours and health status, when delivered in UK settings. The present study examines the outcome of counselling in physiotherapy based on the Transtheoretical Model (TTM) in a sample of elderly individuals with chronic low back pain.
                In a prospective randomised trial with concealed assignment, elderly individuals with chronic low back pain were allocated to two treatment conditions. Both contained 10 sessions of physiotherapy, each of 20min duration. In addition, the experimental group (EG) received 10min counselling prior to every session based on the TTM, also provided by the physiotherapist, and the control group (CG) underwent a placebo ultrasound treatment with an inactivated device to control for the additional attention given to the EG. Assessments took place prior to the treatment (t1), immediately after termination of the treatment (t2), and at a 6-months follow-up. Outcome measures were physical activity calculated from one-week activity diaries, self-reported functional capacity, and range of motion measured by ultrasound topometry.
                A total of 170 individuals (64% female) with a mean age of 70.3 years (SD=4.4, range 65-84) participated in the study. The retention rate was 90%. At t3, both EG and CG showed increased physical activity and functional capacity, but no change in range of motion. Effect sizes were large. Contrary to our hypothesis, however, motivational training did not result in a better outcome compared with placebo treatment.
                The study does not provide evidence that a short TTM-based motivation programme is superior to placebo treatment regarding adherence to activity recommendations. The purpose of this study was to investigate whether the mode of teaching exercises (use of brochures versus therapist teaching) affects whether patients correctly perform the exercises and whether it affects changes in impairment.
                Eighty-seven patients (33 women, 54 men) with neck pain and low back pain were examined. The average age was 48 years (SD = 12.7, range = 21-67).
                Two groups of patients were analyzed. The supervised (physical therapist-instructed) group (n = 47) exercised under the supervision of a physical therapist, whereas the brochure group (n = 40) received their instructions only from one of three brochures. A rating scale was used to assess the correctness of exercise performance. Muscle status was registered using a standardized procedure for determination of muscle force and length. Pain severity was determined by means of a visual analogue scale.
                On the rating scale evaluating the correctness of exercise performance at follow-up, the patients in the supervised group performed better than the patients in the brochure group. In addition, there was a strong correlation between the quality of exercise performance and decrease in pain.
                Exercises learned only from a brochure without being monitored by a physical therapist were done properly by only about half of the patients and appeared to result in fewer improvements in impairments. To investigate the therapeutic effects of different muscle-strengthening exercises on the functional status of patients with knee osteoarthritis (OA).
                One hundred thirty-two patients with bilateral knee OA (Altman Grade II) were sequentially divided into 4 random groups (GI to GIV). The patients in group I received isokinetic muscle-strengthening exercise, group II received isotonic muscle-strengthening exercise, group III received isometric muscle-strengthening exercise, and group IV acted as controls. The changes of muscle power of leg flexion and extension were measured with a Kinetic Communicator dynamometer, and patients' functional status was evaluated by visual analogue scale, ambulation speed, and Lequesne index before and after treatment, and at the follow-up 1 year later.
                The results showed that the patients with OA in each treated group had significant improvement in pain reduction, disability reduction, and in walking speed after treatment and at follow-up when compared with their initial status. Isotonic exercise had the greatest effect on pain reduction after treatment, and fewer participants discontinued the treatment because of exercise knee pain. Isokinetic exercise caused the greatest increase of walking speed and decrease of disability after treatment and at follow-up. The greatest muscle-strength gain in 60 degrees /second angular velocity peak torques was found in the isokinetic and isotonic exercise groups. A significant muscle-strength gain in 180 degrees /second angular velocity peak torques was found only in the isokinetic group after treatment.
                Isotonic exercise is suggested for initial strengthening in patients with OA with exercise knee pain, and isokinetic exercise is suggested for improving joint stability or walking endurance at a later time.

                Effectiveness of isokinetic muscle strengthening exercises for treatment of periarticular soft tissue disorders was compared with and without pulsed and continuous US.
                Outpatient exercise program in a Taiwan medical university hospital.
                One hundred twenty subjects with bilateral knee OA (Altman grade II).
                Subjects were randomized sequentially into 1 of 4 groups. Group I received isokinetic muscular strengthening exercises, group II received isokinetic exercise and continuous US, group III received isokinetic exercise and pulsed US treatment, and group IV was the control group.
                Therapeutic effects of isokinetic exercise were evaluated by changes in ambulation speed and the Lequesne index. In addition, changes in knee range of motion (ROM), visual analog scale for pain, and muscle peak torques during knee flexion and extension were compared. Compliance in each group was recorded.
                Each treated group had increased muscle peak torques and significantly reduced pain and disability after treatment and at follow-up. However, only patients in groups II and III had significant improvement in ROM and ambulation speed after treatment. Fewer participants in group III discontinued treatment due to knee pain during exercise. Patients in group III also showed the greatest increase in walking speed and decrease in disability after treatment and at follow-up. Gains in muscular strength in 60 degrees /s angular velocity peak torques were also noted in groups II and III. However, group III showed the greatest muscular strength gains with 180 degrees /s angular velocity peak torques after treatment and follow-up.
                US treatment could increase the effectiveness of isokinetic exercise for functional improvement of knee OA, and pulsed ultrasound has a greater effect than continuous US. To determine the effectiveness of a behavioral graded activity program (BGA) compared with usual care (UC; exercise therapy and advice) according to the Dutch guidelines for physiotherapy in patients with osteoarthritis (OA) of the hip and/or knee. The BGA intervention is intended to increase activity in the long term and consists of an exercise program with booster sessions, using operant treatment principles.
                We conducted a cluster randomized trial involving 200 patients with hip and/or knee OA. Primary outcome measures were pain (visual analog scale [VAS] and Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]), physical function (WOMAC), and patient global assessment, assessed at weeks 0, 13, 39, and 65. Secondary outcome measures comprised tiredness (VAS), patient-oriented physical function (McMaster Toronto Arthritis Patient Preference Disability Questionnaire [MACTAR]), 5-meter walking time, muscle strength, and range of motion. Data were analyzed according to intent-to-treat principle.
                Both treatments showed short-term and long-term beneficial within-group effects. The mean differences between the 2 groups for pain and functional status were not statistically significant. Significant differences in favor of BGA were found for the MACTAR functional scale and 5-meter walking test at week 65.
                Because both interventions resulted in beneficial long-term effects, the superiority of BGA over UC has not been demonstrated. Therefore, BGA seems to be an acceptable method to treat patients with hip and/or knee OA, with equivalent results compared with UC. This study assessed the effectiveness of a single intervention targeting work style and a combined intervention targeting work style and physical activity on the recovery from neck and upper limb symptoms. Computer workers with frequent or long-term neck and upper limb symptoms were randomised into the work style group (WS, n=152), work style and physical activity group (WSPA, n=156), or usual care group (n=158). The WS and WSPA group attended six group meetings. All meetings focused on behavioural change with regard to body posture, workplace adjustment, breaks and coping with high work demands (WS and WSPA group) and physical activity (WSPA group). Pain, disability at work, days with symptoms and months without symptoms were measured at baseline and after 6 (T1) and 12 months (T2). Self-reported recovery was assessed at T1/T2. Both interventions were ineffective in improving recovery. The work style intervention but not the combined intervention was effective in reducing all pain measures. These effects were present in the neck/shoulder, not in the arm/wrist/hand. For the neck/shoulder, the work style intervention group also showed an increased recovery-rate. Total physical activity increased in all study groups but no differences between groups were observed. To conclude, a group-based work style intervention focused on behavioural change was effective in improving recovery from neck/shoulder symptoms and reducing pain on the long-term. The combined intervention was ineffective in increasing total physical activity. Therefore we cannot draw conclusions on the effect of increasing physical activity on the recovery from neck and upper limb symptoms. Chronic pain is a common and frequently disabling problem in older adults. Clinical guidelines emphasize the need to use multimodal therapies to manage persistent pain in this population. Pain self-management training is a multimodal therapy that has been found to be effective in young to middle-aged adult samples. This training includes education about pain as well as instruction and practice in several management techniques, including relaxation, physical exercise, modification of negative thoughts, and goal setting. Few studies have examined the effectiveness of this therapy in older adult samples.
                This is a randomized, controlled trial to assess the effectiveness of a pain self-management training group intervention, as compared with an education-only control condition. Participants are recruited from retirement communities in the Pacific Northwest of the United States and must be 65 years or older and experience persistent, noncancer pain that limits their activities. The primary outcome is physical disability, as measured by the Roland-Morris Disability Questionnaire. Secondary outcomes are depression (Geriatric Depression Scale), pain intensity (Brief Pain Inventory), and pain-related interference with activities (Brief Pain Inventory). Randomization occurs by facility to minimize cross-contamination between groups. The target sample size is 273 enrolled, which assuming a 20% attrition rate at 12 months, will provide us with 84% power to detect a moderate effect size of.50 for the primary outcome.
                Few studies have investigated the effects of multimodal pain self-management training among older adults. This randomized controlled trial is designed to assess the efficacy of a pain self-management program that incorporates physical and psychosocial pain coping skills among adults in the mid-old to old-old range. To assess the effect of a combined exercise and motivation program on the compliance and level of disability of patients with chronic and recurrent low back pain.
                A double-blind prospective randomized controlled trial.
                Physical therapy outpatient department, tertiary care.
                Ninety-three low back pain patients were randomly assigned to either a standard exercise program (n = 49) or a combined exercise and motivation program (n = 44).
                Patients were prescribed 10 physical therapy sessions and were advised to continue exercising after treatment termination. The motivation program consisted of five compliance-enhancing interventions. Follow-up assessments were performed at 3 1/2 weeks, 4 months, and 12 months.
                Disability (low back outcome score), pain intensity, physical impairment (modified Waddell score, fingertip-to-floor distance, abdominal muscle strength), working ability, motivation, and compliance.
                The patients in the motivation group were significantly more likely to attend their exercise therapy appointments (p = .0005). Four and 12 months after study entry there was a significant difference in favor of the motivation group with regard to the disability score (p = .004) and pain intensity (p < or = .026). At 4 months, there was a significant advantage for the motivation group in the fingertip-to-floor distance (p = .01) and in abdominal muscle strength (p = .018). No significant differences were found in motivation scores, self-reported compliance with long-term exercise, and modified Waddell score. In terms of working ability, there was a trend favoring the combined exercise and motivation program.
                The combined exercise and motivation program increased the rate of attendance at scheduled physical therapy sessions, ie, short-term compliance, and reduced disability and pain levels by the 12-month follow-up. However, there was no difference between the motivation and control groups with regard to long-term exercise compliance. To determine whether Tai Chi or hydrotherapy classes for individuals with chronic symptomatic hip or knee osteoarthritis (OA) result in measurable clinical benefits.
                A randomized controlled trial was conducted among 152 older persons with chronic symptomatic hip or knee OA. Participants were randomly allocated for 12 weeks to hydrotherapy classes (n = 55), Tai Chi classes (n = 56), or a waiting list control group (n = 41). Outcomes were assessed 12 and 24 weeks after randomization and included pain and physical function (Western Ontario and McMaster Universities Osteoarthritis Index), general health status (Medical Outcomes Study Short Form 12 Health Survey [SF-12], version 2), psychological well-being, and physical performance (Up and Go test, 50-foot walk time, timed stair climb).
                At 12 weeks, compared with controls, participants allocated to hydrotherapy classes demonstrated mean improvements (95% confidence interval) of 6.5 (0.4, 12.7) and 10.5 (3.6, 14.5) for pain and physical function scores (range 0-100), respectively, whereas participants allocated to Tai Chi classes demonstrated improvements of 5.2 (-0.8, 11.1) and 9.7 (2.8, 16.7), respectively. Both class allocations achieved significant improvements in the SF-12 physical component summary score, but only allocation to hydrotherapy achieved significant improvements in the physical performance measures. All significant improvements were sustained at 24 weeks. In this almost exclusively white sample, class attendance was higher for hydrotherapy, with 81% attending at least half of the available 24 classes, compared with 61% for Tai Chi.
                Access to either hydrotherapy or Tai Chi classes can provide large and sustained improvements in physical function for many older, sedentary individuals with chronic hip or knee OA. Chronic low back pain is a common problem that has only modestly effective treatment options.
                To determine whether yoga is more effective than conventional therapeutic exercise or a self-care book for patients with chronic low back pain.
                Randomized, controlled trial.
                A nonprofit, integrated health care system.
                101 adults with chronic low back pain.
                12-week sessions of yoga or conventional therapeutic exercise classes or a self-care book.
                Primary outcomes were back-related functional status (modified 24-point Roland Disability Scale) and "bothersomeness" of pain (11-point numerical scale). The primary time point was 12 weeks. Clinically significant change was considered to be 2.5 points on the functional status scale and 1.5 points on the bothersomeness scale. Secondary outcomes were days of restricted activity, general health status, and medication use.
                After adjustment for baseline values, back-related function in the yoga group was superior to the book and exercise groups at 12 weeks (yoga vs. book: mean difference, -3.4 [95% CI, -5.1 to - 1.6] [P < 0.001]; yoga vs. exercise: mean difference, -1.8 [CI, -3.5 to - 0.1] [P = 0.034]). No significant differences in symptom bothersomeness were found between any 2 groups at 12 weeks; at 26 weeks, the yoga group was superior to the book group with respect to this measure (mean difference, -2.2 [CI, -3.2 to - 1.2]; P < 0.001). At 26 weeks, back-related function in the yoga group was superior to the book group (mean difference, -3.6 [CI, -5.4 to - 1.8]; P < 0.001).
                Participants in this study were followed for only 26 weeks after randomization. Only 1 instructor delivered each intervention.
                Yoga was more effective than a self-care book for improving function and reducing chronic low back pain, and the benefits persisted for at least several months. Active physical training is commonly recommended for patients with chronic neck pain; however, its efficacy has not been demonstrated in randomized studies.
                To evaluate the efficacy of intensive isometric neck strength training and lighter endurance training of neck muscles on pain and disability in women with chronic, nonspecific neck pain.
                Examiner-blinded randomized controlled trial conducted between February 2000 and March 2002.
                Participants were recruited from occupational health care systems in southern and eastern Finland.
                A total of 180 female office workers between the ages of 25 and 53 years with chronic, nonspecific neck pain.
                Patients were randomly assigned to either 2 training groups or to a control group, with 60 patients in each group. The endurance training group performed dynamic neck exercises, which included lifting the head up from the supine and prone positions. The strength training group performed high-intensity isometric neck strengthening and stabilization exercises with an elastic band. Both training groups performed dynamic exercises for the shoulders and upper extremities with dumbbells. All groups were advised to do aerobic and stretching exercises regularly 3 times a week.
                Neck pain and disability were assessed by a visual analog scale, the neck and shoulder pain and disability index, and the Vernon neck disability index. Intermediate outcome measures included mood assessed by a short depression inventory and by maximal isometric neck strength and range of motion measures.
                At the 12-month follow-up visit, both neck pain and disability had decreased in both training groups compared with the control group (P<.001). Maximal isometric neck strength had improved flexion by 110%, rotation by 76%, and extension by 69% in the strength training group. The respective improvements in the endurance training group were 28%, 29%, and 16% and in the control group were 10%, 10%, and 7%. Range of motion had also improved statistically significantly in both training groups compared with the control group in rotation, but only the strength training group had statistically significant improvements in lateral flexion and in flexion and extension.
                Both strength and endurance training for 12 months were effective methods for decreasing pain and disability in women with chronic, nonspecific neck pain. Stretching and fitness training are commonly advised for patients with chronic neck pain, but stretching and aerobic exercising alone proved to be a much less effective form of training than strength training. Conducted a treatment-outcome study to investigate the effectiveness of behavioral (BT) or physical therapy (PT) for treating chronic low back pain (CLBP). Thirteen patients received BT; 12 patients received PT. All patients had at least a 6-month history of seeking treatment of CLBP. Prior to treatment patients were assessed in four principal areas of functioning: (1) physical abilities; (2) current physical functioning; (3) psychological and psychosocial functioning; and (4) pain intensity and pain perception. Treatments were conducted in a group (5-8 patients) outpatient setting. Both BT and PT met for 10 weekly 2-hour sessions. BT was designed to address the environmental, social, and emotional influences of the pain experience, depression, and decreased activity from CLBP. PT was based upon traditional rehabilitation theory and was designed to improve low back function. The posttreatment results showed general improvement for patients in both groups, but few treatment-specific differences in outcome measures. The treatment of non-specific chronic low back pain is often based on three different models regarding the development and maintenance of pain and especially functional limitations: the deconditioning model, the cognitive behavioral model and the biopsychosocial model. There is evidence that rehabilitation of patients with chronic low back pain is more effective than no treatment, but information is lacking about the differential effectiveness of different kinds of rehabilitation. A direct comparison of a physical, a cognitive-behavioral treatment and a combination of both has never been carried out so far.
                The effectiveness of active physical, cognitive-behavioral and combined treatment for chronic non-specific low back pain compared with a waiting list control group was determined by performing a randomized controlled trial in three rehabilitation centers. Two hundred and twenty three patients were randomized, using concealed block randomization to one of the following treatments, which they attended three times a week for 10 weeks: Active Physical Treatment (APT), Cognitive-Behavioral Treatment (CBT), Combined Treatment of APT and CBT (CT), or Waiting List (WL). The outcome variables were self-reported functional limitations, patient's main complaints, pain, mood, self-rated treatment effectiveness, treatment satisfaction and physical performance including walking, standing up, reaching forward, stair climbing and lifting. Assessments were carried out by blinded research assistants at baseline and immediately post-treatment. The data were analyzed using the intention-to-treat principle.
                For 212 patients, data were available for analysis. After treatment, significant reductions were observed in functional limitations, patient's main complaints and pain intensity for all three active treatments compared to the WL. Also, the self-rated treatment effectiveness and satisfaction appeared to be higher in the three active treatments. Several physical performance tasks improved in APT and CT but not in CBT. No clinically relevant differences were found between the CT and APT, or between CT and CBT.
                All three active treatments were effective in comparison to no treatment, but no clinically relevant differences between the combined and the single component treatments were found. Self-management courses in arthritis have been shown to improve outcomes and to decrease medical resource utilization. We studied the effectiveness of a mail-delivered arthritis self-management program with the potential for extending these effects more broadly.
                Randomized controlled trial of 375 program participants and 434 controls over a 6 month period. Baseline and 6 month data were analyzed for each group and between groups by paired 2 sample t test. The intervention consists of health assessment questionnaires at 3 month intervals, with computer processed recommendation letters and reports individualized to age, diagnosis, education level, disability, pain, medication, and other patient-specific variables.
                At 6 months, outcomes of function (4.7%; 95% confidence limits 2.7, 6.7), decreased pain (9%; 2.8, 15.2), global vitality (7%; 2.8, 11.2), and joint count (28%; 20, 36) were improved in the program group compared with controls (p < 0.01). Exercise (35%; 26, 44) and self-efficacy (14.7%; 9, 20) were increased in the program group but not controls (p < 0.001). Doctor visits/year were decreased by 16% (3, 29) in the program group compared with controls (p < 0.05) and days missed work or confined to home decreased by 52% (-3, 107) in the program group compared with controls (p = 0.06). At one year, patients in the original program group continued to improve, and the control group, provided with the program in the second 6 months, showed improvement similar to the first 6 months of the original program group.
                A mail-delivered arthritis self-management program can positively affect patient outcomes and can decrease medical resource utilization. The aim of the present study was to evaluate the outcome of a behavioral medicine (BM) rehabilitation program and the outcome of its two main components, compared to a 'treatment-as-usual' control group (CG). The study employed a 4x4 repeated-measures design with four groups and four assessment periods (pre-treatment, post-treatment, 6-month follow-up, and 18-month follow-up). The group studied consisted of subjects on sick leave identified in a nationwide health insurance scheme in Sweden. After inclusion, the subjects were randomized to one of four conditions, which were: (1) behavior-oriented physical therapy (PT); (2) cognitive behavioral therapy (CBT); (3) BM rehabilitation consisting of PT+CBT (BM); (4) a 'treatment-as-usual' CG. The treatments were given over a period of 4 weeks, PT and CBT on a part-time basis and BM on a full-time basis. Outcome variables were sick leave, early retirement, and health-related quality of life (measured using the Short Form Health Survey, SF-36). The results showed that the risk of being granted full-time early retirement was significantly lower for females in PT and CBT compared to the CG during the 18-month follow-up period. However, the total absence from work (sick listing plus early retirement) in days over the 18-month follow-up period was not significantly different in the CG compared to the treatments. On the SF-36, women in CBT and BM reported a significantly better health-related quality of life than women in the CG at the 18-month follow-up. No significant differences for men were found on the SF-36 scales. In conclusion, the results revealed gender differences in the outcome of the treatments and that the components of this BM program yielded as good results as the whole program. This 8 week randomized, double blind clinical trial compared the effect of a combined home based progressive exercise program and treatment with the nonsteroidal medication oxaprozin to treatment with oxaprozin alone on pain and physical functioning in older community dwelling patients with unilateral knee osteoarthritis (OA).
                Efficacy variables measured before and after 8 weeks included (1) pain using the Western Ontario McMaster (WOMAC) pain, physical disability, and stiffness subscales and a 10 point visual analog scale (VAS) before and after self-paced walking (SPW) and stepping (SPS) functional tasks; (2) physical function using the time to complete a self-paced 40 m walk (SPW) and 20 cycles of 2 steps (SPS): (3) physical activity level using the Physical Activity Scale for Elderly (PASE); (4) clinical measures of knee functioning (range of motion). One hundred seventy-nine men and women (mean age 74 +/- 6 yrs) with radiographic evidence of mild/moderate medial compartment OA were randomized to either a progressive home based knee exercise program (n = 88) or a control program (n = 89). All patients were given oxaprozin 1,200 mg per os daily.
                We observed significant reduction from baseline in activity related pain (VAS); and improvement in SPW and SPS test time, passive range of motion, and PASE after 8 weeks in both groups. These changes were significantly greater (p < 0.05) in the exercise versus sham group.
                Addition of a progressive exercise program to nonsteroidal antiinflammatory therapy in patients with knee OA can improve measures of activity and activity related pain more than medication alone. To determine the effects of structured exercise programs on self-reported disability in older adults with knee osteoarthritis.
                A randomized, single-blind clinical trial lasting 18 months conducted at 2 academic medical centers.
                A total of 439 community-dwelling adults, aged 60 years or older, with radiographically evident knee osteoarthritis, pain, and self-reported physical disability.
                An aerobic exercise program, a resistance exercise program, and a health education program.
                The primary outcome was self-reported disability score (range, 1-5). The secondary outcomes were knee pain score (range, 1-6), performance measures of physical function, x-ray score, aerobic capacity, and knee muscle strength.
                A total of 365 (83%) participants completed the trial. Overall compliance with the exercise prescription was 68% in the aerobic training group and 70% in the resistance training group. Postrandomization, participants in the aerobic exercise group had a 10% lower adjusted mean (+/- SE) score on the physical disability questionnaire (1.71 +/- 0.03 vs 1.90 +/- 0.04 units; P<.001), a 12% lower score on the knee pain questionnaire (2.1 +/- 0.05 vs 2.4 +/- 0.05 units; P=.001), and performed better (mean [+/- SE]) on the 6-minute walk test (1507 +/- 16 vs 1349 +/- 16 ft; P<.001), mean (+/-SE) time to climb and descend stairs (12.7 +/- 0.4 vs 13.9 +/- 0.4 seconds; P=.05), time to lift and carry 10 pounds (9.1 +/- 0.2 vs 10.0 +/- 0.1 seconds; P<.001), and mean (+/-SE) time to get in and out of a car (8.7 +/- 0.3 vs 10.6 +/- 0.3 seconds; P<.001) than the health education group. The resistance exercise group had an 8% lower score on the physical disability questionnaire (1.74 +/- 0.04 vs 1.90 +/- 0.03 units; P=.003), 8% lower pain score (2.2 +/- 0.06 vs 2.4 +/- 0.05 units; P=.02), greater distance on the 6-minute walk (1406 +/- 17 vs 1349 +/- 16 ft; P=.02), faster times on the lifting and carrying task (9.3 +/- 0.1 vs 10.0 +/- 0.16 seconds; P=.001), and the car task (9.0 +/- 0.3 vs 10.6 +/- 0.3 seconds; P=.003) than the health education group. There were no differences in x-ray scores between either exercise group and the health education group.
                Older disabled persons with osteoarthritis of the knee had modest improvements in measures of disability, physical performance, and pain from participating in either an aerobic or a resistance exercise program. These data suggest that exercise should be prescribed as part of the treatment for knee osteoarthritis. Behavioral and health status outcomes of an unreinforced, self-help education program for arthritis patients taught by lay persons were examined in 2 ways: a 4-month randomized experiment and a 20-month longitudinal study. At 4 months, experimental subjects significantly exceeded control subjects in knowledge, recommended behaviors, and in lessened pain. These changes remained significant at 20 months. The course was inexpensive and well-accepted by patients, physicians, and other health professionals. This study assessed the impact of a low cost, multicomponent physical activity intervention for older adults with lower extremity osteoarthritis.
                A randomized controlled trial compared the effects of a facility-based multiple-component training program followed by home-based adherence (n = 80) to a wait list control group (n = 70). Assessments were conducted at baseline and at 2 and 6 months following randomization. The training program consisted of range of motion, resistance training, aerobic walking, and education-group problem solving regarding self-efficacy for exercise and exercise adherence. All training group participants developed individualized plans for posttraining adherence.
                Relative to the persons in the control group, individuals who participated in the exercise program experienced a statistically significant improvement in exercise efficacy, a 48.5% increase in exercise adherence, and a 13.3% increase in 6-min distance walk that were accompanied by significant decreases in lower extremity stiffness at 2 and 6 months. Program participants also experienced a significant decrease in lower extremity pain and a borderline significant improvement in efficacy to adhere to exercise over time at 6 months (p =.052). In contrast, persons in the control group deteriorated over time on the efficacy and adherence measures and showed no change on the other measures. No adverse health effects were encountered.
                These benefits indicate that this low-cost intervention may hold great promise as one of a growing number of public health intervention strategies for older adults in the United States with osteoarthritis. To compare a group exercise programme known as the Back to Fitness programme with individual physiotherapy for patients with non-specific low back pain from a materially deprived area.
                This was a randomized controlled trial including 237 physiotherapy patients with back pain lasting more than six weeks. Participants were allocated to either the Back to Fitness programme or to individual physiotherapy, and followed up at three months and 12 months after randomization. The main outcome measure was the Roland Disability Questionnaire. Secondary measures were: SF12, EQ5D, Pain Self-Efficacy Scale. Health care diaries recording patients' use of health care resources were also collected over a 12-month period.
                There were no statistically significant differences in change scores between groups on the primary outcome measure at three months (CI - 2.24 to 0.49) and at 12 months (CI - 1.68 to 1.39). Only minor improvements in disability scores were observed in the Back to Fitness group at three months and 12 months respectively (mean change scores; - 0.89, - 0.77) and in the individual physiotherapy arm (mean change scores; - 0.02, - 0.63). Further analysis showed that patients from the most severely deprived areas were marginally worse at three month follow-up whereas those from more affluent areas tended to improve (CI 0.43 to 3.15).
Interventions such as supervised or individualised exercise therapy and self-management techniques may enhance exercise adherence. However, high-quality, randomised trials with long-term follow up that explicitly address adherence to exercises and physical activity are needed. A standard validated measure of exercise adherence should be used consistently in future studies.
