Seventy-seven patients with neck pain in the primary health care were included in a prospective, randomized clinical trial and randomly assigned to general exercise, McKenzie treatment, or a control group. Seventy patients completed the treatment; response rate 93% at 12-month follow-up. All three groups showed significant improvement regarding the main outcomes, pain intensity and Neck Disability Index, even at 12-month follow-up, but there was no significant difference between the groups. In all, 79% reported that they were better or completely restored after treatment, although 51% reported constant/daily pain. In the McKenzie group compared with the control group, a tendency toward greater improvement was noted for pain intensity at 3 weeks and at 6-month follow-up, and for post-treatment Neck Disability Index. Significant improvement in Distress and Risk Assessment Method scores was shown in the McKenzie group only. The three groups had similar recurrence rates, although after 12 months the McKenzie group showed a tendency toward fewer visits for additional health care. The study did not provide a definite evidence of treatment efficacy in patients with neck pain, however, there was a tendency toward a better outcome with the two active alternatives compared with the control group. A multicenter, randomized controlled trial with unblinded treatment and blinded outcome assessment was conducted. The treatment period was 6 weeks with follow-up assessment after treatment, then at 3, 6, and 12 months.
                To determine the effectiveness of manipulative therapy and a low-load exercise program for cervicogenic headache when used alone and in combination, as compared with a control group.
                Headaches arising from cervical musculoskeletal disorders are common. Conservative therapies are recommended as the first treatment of choice. Evidence for the effectiveness of manipulative therapy is inconclusive and available only for the short term. There is no evidence for exercise, and no study has investigated the effect of combined therapies for cervicogenic headache.
                In this study, 200 participants who met the diagnostic criteria for cervicogenic headache were randomized into four groups: manipulative therapy group, exercise therapy group, combined therapy group, and a control group. The primary outcome was a change in headache frequency. Other outcomes included changes in headache intensity and duration, the Northwick Park Neck Pain Index, medication intake, and patient satisfaction. Physical outcomes included pain on neck movement, upper cervical joint tenderness, a craniocervical flexion muscle test, and a photographic measure of posture.
                There were no differences in headache-related and demographic characteristics between the groups at baseline. The loss to follow-up evaluation was 3.5%. At the 12-month follow-up assessment, both manipulative therapy and specific exercise had significantly reduced headache frequency and intensity, and the neck pain and effects were maintained (P < 0.05 for all). The combined therapies was not significantly superior to either therapy alone, but 10% more patients gained relief with the combination. Effect sizes were at least moderate and clinically relevant.
                Manipulative therapy and exercise can reduce the symptoms of cervicogenic headache, and the effects are maintained. Head repositioning accuracy (HRA) after full range active motion was evaluated in 60 cervicalgic patients. The mean angular error was 7.7 degrees +/- 3.3 (mean +/- SD) and 82% were outside a threshold value of 4.5 degrees. After randomization 30 patients followed a rehabilitation program based on eye-head coupling (RG) and 30 served as a control group (CG). At 10 week follow-up, a greater gain in HRA was observed in the RG (2 degrees +/- 2.7, mean +/- SD) than in the CG (0 +/- 2.6, mean +/- SD) (p = 0.005). Clinical parameters (pain, drug intake, range of motion, and self assessed functional improvement) were also more improved in the RG than in the CG. These data emphasize the role of a neck proprioception alteration in chronic neck pain and suggest that a rehabilitation program based on eye-head coupling should be included in most medical management of cervicalgic patients. The prevalence of neck muscle pain has steadily increased and especially pain from the descending part of the trapezius muscle has been associated with monotonous work tasks such as computer work. Physical exercise is generally recommended as treatment, but it is unclear which type of training is most effective. Our objective was to determine the effectiveness of specific strength training of the painful muscle versus general fitness training without direct involvement of the painful muscle (leg bicycling) on work-related neck muscle pain.
                We conducted a randomized controlled trial and recruited subjects from 7 workplaces characterized by monotonous jobs (e.g., computer-intensive work). Forty-eight employed women with chronic neck muscle pain (defined as a clinical diagnosis of trapezius myalgia) were randomly assigned to 10 weeks of specific strength training locally for the affected muscle, general fitness training performed as leg bicycling with relaxed shoulders, or a reference intervention without physical activity. The main outcome measure was an acute and prolonged change in intensity of neck muscle pain (100-mm visual analog scale [VAS]).
                A decrease of 35 mm (approximately 79%; P<0.001) in the worst VAS pain score over a 10-week period was seen with specific strength training, whereas an acute and transient decrease in pain (5 mm; P<0.05) was found with general fitness training.
                Specific strength training had high clinical relevance and led to marked prolonged relief in neck muscle pain. General fitness training showed only a small yet statistically significant acute pain reduction. To investigate the effect of transcutaneous electrical nerve stimulation (TENS) on acupuncture points and neck exercise in chronic neck pain patients.
                A randomized clinical trial.
                Hospital-based practice.
                Two hundred and eighteen patients with chronic neck pain.
                Subjects were randomized into three groups, receiving either (1) TENS over the acupuncture points plus infrared irradiation (TENS group); (2) exercise training plus infrared irradiation (exercise group); or (3) infrared irradiation alone (control); twice a week for six weeks.
                The values of verbal numeric pain scale, Northwick Park Neck Pain Questionnaire, and isometric neck muscle strength were assessed before, at the end of the six-week treatment, and at the six-month follow-up.
                Results demonstrated that after the six-week treatment, significant improvement in the verbal numerical pain scale was found only in the TENS group (0.60+/-2.54, p = 0.027) and the exercise group (1.57+/-2.67, p < 0.001). Though significant reduction in Northwick Park Neck Pain Questionnaire score was found in all three groups, post-hoc tests showed that both the TENS and the exercise group produced better improvement (0.38+/-0.60% and 0.39+/-0.62% respectively) than the control group (0.23+/-0.63%). Significant improvement (p = < 0.001 to 0.03) in neck muscle strength was observed in all three groups, however, the improvement in the control group was not clinically significant and it could not be maintained at the six-month follow-up.
                After the six-week treatment, patients in the TENS and exercise group had a better and clinically relevant improvement in disability, isometric neck muscle strength, and pain. All the improvements in the intervention groups were maintained at the six-month follow-up. Randomized clinical trial.
                To compare the effects of spinal manipulation combined with low-tech rehabilitative exercise, MedX rehabilitative exercise, or spinal manipulation alone in patient self-reported outcomes over a two-year follow-up period.
                There have been few randomized clinical trials of spinal manipulation and rehabilitative exercise for patients with neck pain, and most have only reported short-term outcomes.
                One hundred ninety-one patients with chronic neck pain were randomized to 11 weeks of one of the three treatments. Patient self-report questionnaires measuring pain, disability, general health status, improvement, satisfaction, and OTC medication use were collected after 5 and 11 weeks of treatment and 3, 6, 12, and 24 months after treatment. Data were analyzed taking into account all time points using repeated measures analyses.
                Ninety-three percent (178) of randomized patients completed the 11-week intervention phase, and 76% (145) provided data at all evaluation time points over the two-year follow-up period. A difference in patient-rated pain with no group-time interaction was observed in favor of the two exercise groups [F(2141) = 3.2; P= 0.04]. There was also a group difference in satisfaction with care [F(2143) = 7.7; P= 0.001], with spinal manipulation combined with low-tech rehabilitative exercise superior to MedX rehabilitative exercise (P = 0.02) and spinal manipulation alone (P < 0.001). No significant group differences were found for neck disability, general health status, improvement, and OTC medication use, although the trend over time was in favor of the two exercise groups.
                The results of this study demonstrate an advantage of spinal manipulation combined with low-tech rehabilitative exercise and MedX rehabilitative exercise versus spinal manipulation alone over two years and are similar in magnitude to those observed after one-year follow-up. These results suggest that treatments including supervised rehabilitative exercise should be considered for chronic neck pain sufferers. Further studies are needed to examine the cost effectiveness of these therapies and how spinal manipulation compares to no treatment or minimal intervention. Randomized controlled trial.
                To evaluate whether qigong is more effective than no treatment and not inferior to exercise therapy.
                Lifetime prevalence of chronic neck pain is close to 50%. Qigong is often used by patients, although, the evidence is still unclear.
                Patients (aged 20-60 years) with chronic neck pain (visual analog scale, VAS ≥ 40 mm) were randomized to 1) qigong or 2) exercise therapy (18 sessions over 6 months) or 3) waiting list (no treatment). At baseline and after 3 and 6 months, patients completed standardized questionnaires assessing neck pain (VAS), neck pain and disability, and quality of life (Short Form SF-36 questionnaire, SF-36). The primary endpoint was average pain in the last 7 days on VAS at 6-month follow-up. Statistical analysis included generalized estimation equation models adjusted for baseline values and patient expectation.
                A total of 123 patients (aged 46 ± 11 years, 88% women) suffering from chronic neck pain for 3.2 (SD ± 1.6) years were included. After 6 months, a significant difference was seen between the qigong and waiting list control groups (VAS mean difference: -14 mm [95%CI = -23.1 to -5.4], P = 0.002). Mean improvements in the exercise group were comparable to those in the qigong group (difference between groups -0.7 mm [CI = -9.1 to 7.7]) but failed to show statistical significance (P = 0.092). Neck pain and disability, and SF-36 results also yielded superiority of qigong over no treatment and similar results in the qigong and exercise therapy groups.
                Qigong was more effective than no treatment in patients with chronic neck pain. Further studies could be designed without waiting list control and should use a larger sample to clarify the value of qigong compared to exercise therapy. To evaluate the effectiveness of treatment with collar or physiotherapy compared with a wait and see policy in recent onset cervical radiculopathy.
                Randomised controlled trial.
                Neurology outpatient clinics in three Dutch hospitals.
                205 patients with symptoms and signs of cervical radiculopathy of less than one month's duration
                Treatment with a semi-hard collar and taking rest for three to six weeks; 12 twice weekly sessions of physiotherapy and home exercises for six weeks; or continuation of daily activities as much as possible without specific treatment (control group).
                Time course of changes in pain scores for arm and neck pain on a 100 mm visual analogue scale and in the neck disability index during the first six weeks.
                In the wait and see group, arm pain diminished by 3 mm/week on the visual analogue scale (beta=-3.1 mm, 95% confidence interval -4.0 to -2.2 mm) and by 19 mm in total over six weeks. Patients who were treated with cervical collar or physiotherapy achieved additional pain reduction (collar: beta=-1.9 mm, -3.3 to -0.5 mm; physiotherapy: beta=-1.9, -3.3 to -0.8), resulting in an extra pain reduction compared with the control group of 12 mm after six weeks. In the wait and see group, neck pain did not decrease significantly in the first six weeks (beta=-0.9 mm, -2.0 to 0.3). Treatment with the collar resulted in a weekly reduction on the visual analogue scale of 2.8 mm (-4.2 to -1.3), amounting to 17 mm in six weeks, whereas physiotherapy gave a weekly reduction of 2.4 mm (-3.9 to -0.8) resulting in a decrease of 14 mm after six weeks. Compared with a wait and see policy, the neck disability index showed a significant change with the use of the collar and rest (beta=-0.9 mm, -1.6 to -0.1) and a non-significant effect with physiotherapy and home exercises.
                A semi-hard cervical collar and rest for three to six weeks or physiotherapy accompanied by home exercises for six weeks reduced neck and arm pain substantially compared with a wait and see policy in the early phase of cervical radiculopathy. Trial registration Clinical trials NCT00129714. 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. Regular physical exercise is a cornerstone in rehabilitation programs, but adherence to comprehensive exercise remains low. This study determined the effectiveness of small daily amounts of progressive resistance training for relieving neck/shoulder pain in healthy adults with frequent symptoms; 174 women and 24 men working at least 30 h per week and with frequent neck/shoulder pain were randomly assigned to resistance training with elastic tubing for 2 or 12 minutes per day 5 times per week, or weekly information on general health (control group). Primary outcomes were changes in intensity of neck/shoulder pain (scale 0 to 10), examiner-verified tenderness of the neck/shoulder muscles (total tenderness score of 0 to 32), and isometric muscle strength at 10 weeks. Compared with the control group, neck/shoulder pain and tenderness, respectively, decreased 1.4 points (95% confidence interval -2.0 to -0.7, p<0.0001) and 4.2 points (95% confidence interval -5.7 to -2.7, p<0.0001) in the 2-minute group and 1.9 points (95% confidence interval -2.5 to -1.2, p<0.0001) and 4.4 points (95% confidence interval -5.9 to -2.9, p<0.0001) in the 12-minute group. Compared with the control group, muscle strength increased 2.0 Nm (95% confidence interval 0.5 to 3.5Nm, p=0.01) in the 2-minute group and 1.7Nm (95% confidence interval 0.2 to 3.3 Nm, p=0.02) in the 12-minute group. In conclusion, as little as 2 minutes of daily progressive resistance training for 10 weeks results in clinically relevant reductions of pain and tenderness in healthy adults with frequent neck/shoulder symptoms. Trial registration: www.isrctn.org/ISRCTN60264809. In generally healthy adults with frequent neck/shoulder muscle pain, as little as 2 minutes of daily progressive resistance training reduces pain and tenderness.

The effects of group gymnastics on neck pain were studied among 44 women in a printing company. A randomized cross-over design was used with two groups matched according to the work task, frequency of symptoms, and age. The treatment consisted of gymnastics for 45 min once a week for 10 weeks. Neck pain was rated by visual analogue scale and pressure pain sensitivity of the neck muscles was measured with an algometer. The results showed no clear effects of the group gymnastics program. An equal and significant reduction in pain ratings was seen in both groups after the first intervention in the spring. Recurrence of symptoms was seen in both groups in September, and no significant reduction in pain occurred during the second intervention in the autumn. The results suggest a seasonal variation in neck symptoms which has to be considered when planning or evaluating intervention studies. nan To investigate the effects of therapeutic exercises and sleeping neck support contoured pillows on patients with chronic neck pain.
                Using a factorial design in a prospective clinical trial, participants were equally allocated at random to 4 treatment groups in the study: (1) placebo control, of hot or cold packs and massage; (2) sleeping neck support pillow and placebo; (3) active neck exercises and placebo; and (4) combined exercise and sleeping neck support pillow and placebo. Participants were treated by physical therapists over a 6 week period and assessed by masked independent assessors at 0, 3, 6, 12, 24 weeks, and 12 months, with the 12 week assessment being the primary decision time. The primary outcome measure was the Northwick Park Neck Pain Questionnaire (NPQ).
                For the 128/151 (85%) participants tested at 12 weeks, the NPQ descriptive statistics of count, mean (standard deviation) were: Initial: 128, 31.0 (11.3) at Week 12; All: 128, 18.5 (11.6); Control: 34, 18.6 (10.0); Pillow: 32, 21.5 (13.1); Active neck exercises: 29, 20.1 (11.6); and Combined: 33, 14.1 (10.6). Factorial analysis of variance showed that the main effects of Exercise (p = 0.146) and Pillow (p = 0.443) were not statistically significant; but the interaction of Exercise plus Pillow (p = 0.029) was statistically significant and clinically meaningful.
                Treatment by physiotherapists trained to teach both exercises and the use of a neck support pillow achieved the most favorable benefit for participants with chronic neck pain; either strategy alone was not more effective than a control regimen. Time was an important cofactor. Randomized, double-blind, placebo controlled trial.
                To determine the effect of a C1-C2 self-sustained natural apophyseal glide (SNAG) on cervicogenic headache.
                Cervicogenic headache is a common condition causing significant disability. Recent studies have shown a high incidence of C1-C2 dysfunction, evaluated by the flexion-rotation test (FRT), in subjects with cervicogenic headache. To manage this dysfunction, Mulligan has described a C1-C2 self-SNAG, though no studies have investigated the efficacy of this intervention approach.
                A sample of 32 subjects (mean _ SD age, 36 +/- 3 years) with cervicogenic headache and FRT limitation were randomized into a C1-C2 self-SNAG or placebo group. After an initial instruction and practice visit in the clinic, interventions consisted of exercises applied independently by the subject twice daily at home on a continual basis. FRT range was measured twice, before and immediately after the instruction and practice visit. Headache symptoms were determined by a headache index over time, assessed by questionnaire preintervention, at 4 weeks postintervention, and at 12 months postintervention.
                No differences were found in baseline measures between groups. Immediately after the initial instruction and practice visit performed with the supervision of the therapist, FRT range increased by 15 degrees (SD, 9) for the C1-C2 self-SNAG group (P < .001), which was significantly more than 5 degrees (SD, 5) for the placebo intervention (P < .001). There was also a significant interaction for the variable headache index between group and time (P < .001), indicating that group difference was dependent on time. There was no difference in headache index scores at baseline between groups. Headache index scores were substantially less in the C1-C2 self-SNAG group (mean +/- SD points at 4 weeks, 31 +/- 9; mean +/- SD points at 12 months, 24 +/- 9) compared to the placebo group (mean +/- SD points at 4 weeks, 51 +/- 15; mean +/- SD points at 12 months, 44 +/- 13) at 4 weeks (P < .001) and 12 months (P < .001), with an overall (+/-SD) reduction of 54% (+/-17%) for the individuals in the C1-C2 self-SNAG group.
                These results provide evidence for the efficacy of the C1-C2 self-SNAG technique in the management of individuals with cervicogenic headache. Whiplash-associated disorders are common and incur considerable expense in social and economic terms. There are no known effective treatments for those people whose pain and disability persist beyond 3 months. We conducted a randomized, assessor-blinded, controlled trial at two centres in Australia. All participants received 3 advice sessions. In addition the experimental group participated in 12 exercise sessions over 6 weeks. Primary outcomes were pain intensity, pain bothersomeness and function measured at 6 weeks and 12 months. Exercise and advice was more effective than advice alone at 6 weeks for all primary outcomes but not at 12 months. The effect of exercise on the 0-10 pain intensity scale was -1.1 (95%CI -1.8 to -0.3, p=0.005) at 6 weeks and -0.2 (0.6 to -1.0, p=0.59) at 12 months; on the bothersomeness scale the effect was -1.0 (-1.9 to -0.2, p=0.003) at 6 weeks and 0.3 (-0.6 to 1.3, p=0.48) at 12 months. The effect on function was 0.9 (0.3 to 1.6, p=0.006) at 6 weeks and 0.6 (-0.1 to 1.4, p=0.10) at 12 months. High levels of baseline pain intensity were associated with greater treatment effects at 6 weeks and high levels of baseline disability were associated with greater treatment effects at 12 months. In the short-term exercise and advice is slightly more effective than advice alone for people with persisting pain and disability following whiplash. Exercise is more effective for subjects with higher baseline pain and disability. The aim of this study was to evaluate the effectiveness of qigong compared with exercise therapy and no treatment. Elderly patients with chronic neck pain (>6 months) were randomly assigned to qigong or exercise therapy (each 24 sessions over a period of 3 months) or to a waiting list control. Patients completed standardized questionnaires at baseline and after 3 and 6 months. The main outcome measure was average neck pain on the visual analogue scale after 3 months. Secondary outcomes were neck pain and disability (NPAD) and quality of life (SF-36). One hundred seventeen patients (age, 76 +/- 8 years, 95% women) were included in the intention-to-treat analysis. The average duration of neck pain was 19.0 +/- 14.9 years. After 3 months, no significant differences were observed between the qigong group and the waiting list control group (visual analogue scale mean difference, -11 mm [CI, -24.0; 2.1], P = .099) or between the qigong group and the exercise therapy group (-2.5 mm [ - 15.4; 10.3], P = .699). Results for the NPAD were similar (qigong vs waiting list -6.7 (-15.4; 2.1), P = .135; qigong vs exercise therapy 2.3 (-6.2; 10.8); P = .600). We found no significant effect after 3 months of qigong or exercise therapy compared with no treatment. Further studies should include outcomes more suitable to elderly patients, longer treatment, and patients with less chronic pain.
                In a randomized controlled study, we evaluated whether a treatment of 24 qigong sessions over a period of 3 months is (1) superior to no treatment and (2) superior to the same amount of exercise therapy in elderly patients (age, 76 +/- 8 years, 95% women) with long-term chronic neck pain (19.0 +/- 14.9 years). After 3 and 6 months, we found no significant differences for pain, neck pain, disability, and quality of life among the 3 groups. Evidence indicates that supervised home exercises, combined or not with manual therapy, can be beneficial for patients with non-specific chronic neck pain (NCNP). The objective of the study is to investigate the efficacy of preventive spinal manipulative therapy (SMT) compared to a no treatment group in NCNP patients. Another objective is to assess the efficacy of SMT with and without a home exercise program.
                Ninety-eight patients underwent a short symptomatic phase of treatment before being randomly allocated to either an attention-group (n = 29), a SMT group (n = 36) or a SMT + exercise group (n = 33). The preventive phase of treatment, which lasted for 10 months, consisted of meeting with a chiropractor every two months to evaluate and discuss symptoms (attention-control group), 1 monthly SMT session (SMT group) or 1 monthly SMT session combined with a home exercise program (SMT + exercise group). The primary and secondary outcome measures were represented by scores on a 10-cm visual analog scale (VAS), active cervical ranges of motion (cROM), the neck disability index (NDI) and the Bournemouth questionnaire (BQ). Exploratory outcome measures were scored on the Fear-avoidance Behaviour Questionnaire (FABQ) and the SF-12 Questionnaire.
                Our results show that, in the preventive phase of the trial, all 3 groups showed primary and secondary outcomes scores similar to those obtain following the non-randomised, symptomatic phase. No group difference was observed for the primary, secondary and exploratory variables. Significant improvements in FABQ scores were noted in all groups during the preventive phase of the trial. However, no significant change in health related quality of life (HRQL) was associated with the preventive phase.
                This study hypothesised that participants in the combined intervention group would have less pain and disability and better function than participants from the 2 other groups during the preventive phase of the trial. This hypothesis was not supported by the study results. Lack of a treatment specific effect is discussed in relation to the placebo and patient provider interactions in manual therapies. Further research is needed to delineate the specific and non-specific effects of treatment modalities to prevent unnecessary disability and to minimise morbidity related to NCNP. Additional investigation is also required to identify the best strategies for secondary and tertiary prevention of NCNP.
                ClinicalTrials.gov: NCT00566930. The study was a randomized, controlled trial with blinded outcome assessment. A 6-week intervention was followed up directly afterwards and after 12 months.
                The purpose was to evaluate the preventive efficacy of a neck/shoulder exercise regimen for neck pain in air force helicopter pilots.
                Neck pain is a significant medical problem in modern military aviation. Research shows neck-muscle dysfunction in subjects with various neck disorders. So far, evidence for neck exercise as prevention or early intervention is sparse, and few trials use randomized controlled design.
                Sixty-eight helicopter pilots on active flying duty with or without neck pain were randomly assigned to a supervised neck/shoulder exercise regimen or a control group receiving no such regimen. The key outcome was change in the prevalence of neck pain cases at the 12-month follow-up, rated for the previous week and the previous 3 months. Secondary outcomes included neck-flexor surface electromyographic activity during active craniocervical flexion and pain-related fear regarding physical activity. In addition, a secondary regression analysis included preintervention predictors that may be associated with change in prevalence of neck-pain cases at the 12-month follow-up.
                Eighty-two percent (56/68) of the participants assigned at random completed the intervention and provided data at month 12. Regression analysis showed a reduction in the prevalence of neck pain cases in the exercise group, which was significant for pain ratings during the previous week, OR = 3.2 (95% CI = 1.3-7.8), and previous 3 months, OR = 1.9 (95% CI = 1.2-3.2). Electromyographic activity at the highest contraction level was significantly reduced in the exercise group, P < 0.05, whereas no between-groups effect emerged for pain-related fear. Results from the secondary analysis showed that general strength training for more than 1 hour per week before the intervention predicted reduction in prevalence of pain at follow-up.
                A supervised neck/shoulder exercise regimen was effective in reducing neck pain cases in air force helicopter pilots. This was supported by improvement in neck-flexor function postintervention in regimen members. However, no effect emerged for pain-related fear. General strength training before the intervention predicted reduction in prevalence of pain at follow-up. To evaluate the effect of acupuncture combined with physiotherapy in comparison with acupuncture and physiotherapy performed alone in different parameters; pain intensity, muscle tension, functional disability and muscle strength in the treatment of tension neck syndrome (TNS).
                A prospective, comparative clinical trial.

                TNS can occur in computer users. Acupuncture has been one alternative treatment in physiotherapeutic rehabilitation of musculoskeletal disorders.
                Forty-six patients with TNS. Interventions: Patients were allocated into three groups: Group-1 received physiotherapy (therapeutic exercises) combined with acupuncture; Group-2, acupuncture alone, and Group-3, physiotherapy alone; over a period of 10 weeks, with one or two sessions weekly.
                All patients had completed the protocols and were assessed using a visual analogue scale for pain intensity (VASpain) and muscle tension (VASmt), the Neck Disability Index: Brazilian Portuguese version for functional disability, and the cranio-cervical Flexion Test for isometric neck muscle strength (INMS); in the periods before treatment (baseline), after 10 weeks of treatment, and after 6 months of follow-up.
                All groups showed significant improvement (p < 0.001) in these parameters after 10 weeks of treatment and after 6 months of follow-up. Group-1 was superior to Group-3 in pain and functional disability improvements (p<0.05); and Group-1 was superior to both Group-2 (p < 0.01) and Group-3 (p < 0.05) in INMS. After 6 months of follow-up, the improvements of all groups were maintained (p < 0.05).
                The data suggested that acupuncture effect may facilitate and/or enhance physiotherapy performance in musculoskeletal rehabilitation for tension neck syndrome.
Low to moderate quality evidence supports the use of specific cervical and scapular stretching and strengthening exercise for chronic neck pain immediately post treatment and intermediate term, and cervicogenic headaches in the long term. Low to moderate evidence suggests no benefit for some upper extremity stretching and strengthening exercises or a general exercise program.  Future trials should consider using an exercise classification system to establish similarity between protocols and adequate sample sizes. Factorial trials would help determine the active treatment agent within a treatment regimen where a standardized representation of dosage is essential. Standardized reporting of adverse events is needed for balancing the likelihood of treatment benefits over potential harms.
