nan To assess the effects of acetic acid iontophoresis (AAI) and ultrasound on calcifying tendinitis of the shoulder, and to determine the relation between changes in the radiological measures of calcium deposit (CD) and shoulder function.
                Randomized control trial.
                General community, private practice.
                Twenty-two adults (7 men, 15 women) with a calcifying tendinitis of the shoulder, without associated conditions, stratified according to the type of lesions (X-ray: type I, fleecy appearance: type II, homogeneous), were randomly allocated to an experimental (EXP, n = 11) or to a control (CTL, n = 10) group.
                CTL group, no treatment; EXP group, nine treatments including AAI (5% acetic acid solution via the negative electrode, 5mA galvanic current, 20 minutes) followed by continuous ultrasound (0.8w/cm2, 1MHz, 5 minutes).
                Area and density of the CD, passive shoulder abduction (range of motion [ROM]), pain intensity.
                Significant reduction in the area and density of CD (ANCOVA, p = .01 and .03) over time in the EXP and CTL groups, but no significant difference between groups for any of the variables measured. The decrease in the area of CD in type I lesions (n = 5) was larger (Mann-Whitney U test, p < .01) than in type II (n = 16) lesions. The relation was stronger (rs = .90) between changes in area and density of CD than between ROM and pain (rs = -.67). Correlations were weak (rs = .21 to .41) between radiological and functional changes.
                The reduction in CD area and density likely results from a natural process rather than treatment (AAI and ultrasound); type I lesions (resorptive phase) are more likely to display resorption of the CD than type II lesions (formative phase). Reduction of the CD area does not necessary result in a functional improvement. The aim of this study was to evaluate the efficacy of a physical therapy approach to the treatment of shoulder pain. Subjects. Sixty-six volunteers with shoulder pain believed to be of local mechanical origin were randomly allocated to either a treatment group or a control group.
                Subjects in the treatment group received 1 month of physical therapy aimed at restoring function of their shoulder muscles. Subjects in the control group received no treatment. Outcome measurements of pain intensity, range of motion (ROM), isometric muscle force, functional impairment, and self-perception of improvement were obtained by blinded assessment.
                Subjects in the treatment group showed improvement in pain-free abduction and flexion ROM, functional impairment, and self-perception of improvement. The control group deteriorated slightly over the experimental period in ROM and functional impairment measures.
                These results suggest that the physical therapy approach used in this study is effective in improving shoulder function in subjects experiencing pain of mechanical origin. The results also provide little evidence of spontaneous recovery over a 1-month period. Ultrasound (US) is used widely to treat patients with supraspinatus tendinitis, subacromial bursitis, or adhesive capsulitis (SSA). No double blind studies of US in the treatment of SSA, however, have been conducted. This study was designed to determine whether the addition of US can further decrease pain and increase range of motion in those receiving the usual courses of ROM exercises and nonsteroidal anti-inflammatory drugs (NSAIDs) or ROM exercises in patients with SSA. Twenty patients with SSA were randomized to receive true or sham US three times a week for four weeks. All other aspects of treatment remained constant (ROM exercises and NSAIDs or ROM exercises). The physician, the physical therapist, and the patients were blinded throughout the study regarding the delivery of the true or sham US. Of the multiple variables analyzed (pain, ROM, and function), no significant difference was found between the sham or true US groups. Although the study group was small, the results suggest that US is of little or no benefit when combined with ROM exercises and NSAIDs or ROM exercises in the treatment of SSA. Cost effective treatment is needed for common self limiting rheumatological conditions. Periarthritis of the shoulder is an example. There is no consensus for one type of treatment, though local steroids or physiotherapy are conventionally used. Their cost and efficacy were compared in a prospective randomised observer-blind trial--in essence a medical audit of the treatment of a common rheumatological problem. Sixty two consecutive patients presenting with a painful stiff shoulder were studied. Patients with coexistent diseases like cervical spondylosis or a stroke were excluded. They were randomly allocated to receive local steroids, six weeks' physiotherapy, or both. The three groups were of similar age, sex, and disease severity. Assessments of pain and shoulder movement were made initially, at six weeks, and at six months by a 'blinded' observer. Physiotherapy was given by one therapist and injections by one physician. All three groups showed significant improvements by six weeks, with further improvement at six months. Improvements were identical in all three groups. No treatment gave complications. The costs of treatment varied: an injection of triamcinolone cost 2.10 pounds; a six week course of physiotherapy cost 48.50 pounds; combination treatment cost 50.60 pounds. Patients expect treatment for a painful stiff shoulder. The results show that local steroid injections are as effective as physiotherapy alone or a combination. They provide rapid treatment and are less expensive. In the uncomplicated case a local steroid injection is the most cost effective treatment. The potential benefit of magnetotherapy was investigated in 47 consecutive outpatients with periarthritis of the shoulder. Using a controlled triple-blind study design, one group of patients received hot pack applications and passive manual stretching and pulley exercises; the other group received the same therapy plus magnetotherapy. Treatment was administered three times a week. For a maximum of three months, a standardized treatment protocol was used. There was no significant improvement in pain reduction or in range of motion with electromagnetic field therapy. After 12 weeks of therapy, the patients who received magnetotherapy showed mean pain scores of 1.5 (+/- .61 SD) at rest, 2.2 (+/- .76 SD) on movement, and 1.9 (+/- .94 SD), on lying, compared to scores for the control group of 1.4 (+/- .65 SD), 2.2 (+/- .7 SD), and 1.9 (+/- .95 SD), respectively. Linear pain scale scores improved from 71 to 21 for both groups. At 12 weeks the gain in range of motion was mean 109 degrees +/- 46.8 in patients receiving electromagnetic field therapy, compared to 122 degrees +/- 33.4 for the controls (not significant). At entry, the functional handicap score was 53.5 for both groups. At 12 weeks, it was 24 for the magnetotherapy group and 17 for the control group (difference not significant). In conclusion, this study showed no benefit from magnetotherapy in the pain score, range of motion, or improvement of functional status in patients with periarthritis of the shoulder. Although ultrasound therapy is used to treat calcific tendinitis of the shoulder, its efficacy has not been rigorously evaluated. We conducted a randomized, double-blind comparison of ultrasonography and sham insonation in patients with symptomatic calcific tendinitis verified by radiography. Patients were assigned to receive 24 15-minute sessions of either pulsed ultrasound (frequency, 0.89 MHz; intensity, 2.5 W per square centimeter; pulsed mode, 1:4) or an indistinguishable sham treatment to the area over the calcification. The first 15 treatments were given daily (five times per week), and the remainder were given three times a week for three weeks. Randomization was conducted according to shoulders rather than patients, so a patient with bilateral tendinitis might receive either or both therapies.
                We enrolled 63 consecutive patients (70 shoulders). Fifty-four patients (61 shoulders) completed the study. There were 32 shoulders in the ultrasound-treatment group and 29 in the sham-treatment group. After six weeks of treatment, calcium deposits had resolved in six shoulders (19 percent) in the ultrasound-treatment group and decreased by at least 50 percent in nine shoulders (28 percent), as compared with respective values of zero and three (10 percent) in the sham-treatment group (P=0.003). At the nine-month follow-up visit, calcium deposits had resolved in 13 shoulders (42 percent) in the ultrasound-treatment group and improved in 7 shoulders (23 percent), as compared with respective values of 2 (8 percent) and 3 (12 percent) in the sham-treatment group (P=0.002). At the end of treatment, patients who had received ultrasound treatment had greater decreases in pain and greater improvements in the quality of life than those who had received sham treatment; at nine months, the differences between the groups were no longer significant.
                In patients with symptomatic calcific tendinitis of the shoulder, ultrasound treatment helps resolve calcifications and is associated with short-term clinical improvement. nan Forty-two patients with frozen shoulder were followed up closely for eight months. They were all taught pendular exercises and randomly allocated to one of four treatment groups: (a) intraarticular steroids, (b) mobilisations , (c) ice therapy, (d) no treatment. This study has shown that there is little long-term advantage in any of the treatment regimens but that steroid injections may benefit pain and range of movement in the early stages of the condition.
The small sample sizes, variable methodological quality and heterogeneity in terms of population studied, physiotherapy intervention employed and length of follow up of randomised controlled trials of physiotherapy interventions results in little overall evidence to guide treatment. There is evidence to support the use of some interventions in specific and circumscribed cases. There is a need for trials of physiotherapy interventions for specific clinical conditions associated with shoulder pain, for shoulder pain where combinations of physiotherapy interventions, as well as, physiotherapy interventions as an adjunct to other, non physiotherapy interventions are compared. This is more reflective of current clinical practice. Trials should be adequately powered and address key methodological criteria such as allocation concealment and blinding of outcome assessor.
