Effectiveness of physiotherapy and costs in patients with clinical signs of shoulder impingement syndrome: One-year follow-up of a randomized controlled trial.

OBJECTIVES: To investigate the effect of manual physiotherapy and exercises compared with exercises alone in patients with shoulder impingement syndrome one year after inclusion. DESIGN: Randomized controlled trial. SUBJECTS: Patients with shoulder impingement of more than 4 weeks. METHODS: The intervention group received individualized manual physiotherapy plus individualized exercises; the control group received individualized exercises only. Both groups had 10 treatments over 5 weeks; afterwards all patients continued their exercises for another 7 weeks at home. Primary outcomes were the Shoulder Pain and Disability Index and Patients' Global Impression of Change. The Generic Patient-Specific Scale was used as secondary outcome. Costs were recorded in a log-book. RESULTS: Ninety patients were included in the study and 87 could be analyzed at 1-year follow-up. Both groups showed significant improvements in all outcome measures, but no difference was detected between the groups. Only costs differed significantly in favour of the control group (p = 0.03) after 5 weeks. CONCLUSION: Individualized exercises resulted in lower costs than manual physiotherapy and showed a significant effect on pain and functioning within the whole group after one year. Exercises should therefore be considered as a basic treatment. Due to the progressive improvement that occurred during the follow-up period with individualized exercises further treatments should be delayed for 3 to 4 months.

Influence of fear-avoidance beliefs on disability in patients with subacromial shoulder pain in primary care: a secondary analysis.

BACKGROUND: Little information exists about the role of fear-avoidance beliefs and catastrophizing in subacromial pain syndrome. OBJECTIVE: The purpose of this study was to investigate the associations among pain, catastrophizing, fear, and disability and the contribution of fear-avoidance beliefs to disability at baseline and at 3-month follow-up. DESIGN: A cross-sectional and longitudinal analysis was conducted. METHODS: Baseline demographic and clinical data, including fear-avoidance beliefs and catastrophizing, of 90 patients were assessed for this analysis. Disability was measured with the Shoulder Pain and Disability Index at baseline and at 3-month follow-up. First, bivariate and partial correlations were calculated among pain, fear-avoidance beliefs, catastrophizing, and disability, based on the fear-avoidance model. Second, the contribution of fear-avoidance beliefs to disability at baseline and at 3-month follow-up was examined with hierarchical regression analyses. RESULTS: Correlations between clinical variables and disability were largely in line with the fear-avoidance model. Regression analyses identified a significant contribution of fear-avoidance beliefs to baseline disability but not to disability at 3 months. LIMITATIONS: Patients with subacromial pain syndrome were studied; therefore, the results should be transferred with caution to other diagnoses. A modified version of the Fear-Avoidance Beliefs Questionnaire was used, which was not validated for this patient group. CONCLUSIONS: Fear-avoidance beliefs contribute significantly to baseline disability but not to disability change scores after 3-month follow-up. Duration of complaints and baseline disability were the main factors influencing disability change scores. Although the results help to improve understanding of the role of fear-avoidance beliefs, further studies are needed to fully understand the influence of psychological and clinical factors on the development of disability in patients with subacromial shoulder pain.

Physiotherapy in patients with clinical signs of shoulder impingement syndrome: a randomized controlled trial.

OBJECTIVE: To investigate the effect of individualized manual physiotherapy and exercises compared with individualized exercises alone in patients with shoulder impingement syndrome. DESIGN: Randomized controlled trial. SUBJECTS: Patients with shoulder impingement of more than 4 weeks' duration. METHODS: Patients in the intervention group were treated with individually adapted exercises and examination-based physiotherapy. Controls were treated with individually adapted exercises only. Both groups had 10 treatment sessions over a period of 5 weeks and subsequently continued their exercises at home for another 7 weeks. Results were analysed at 5 and 12 weeks after the start of the study. Primary outcome measures were: Shoulder Pain and Disability Index, and Patient's Global Impression of Change. Secondary outcome measures were: mean weekly pain score; Generic Patient-Specific Scale; and Patients' Satisfaction with Treatment. RESULTS: A total of 46 patients were randomized to the intervention group and 44 to the control group. Although both groups showed significant improvements, there was no difference between groups for the primary and secondary outcomes at any time. Only the results for mean pain differed at 5 weeks in favour of the intervention group. CONCLUSION: Individually adapted exercises were effective in the treatment of patients with shoulder impingement syndrome. Individualized manual physiotherapy contributed only a minor amount to the improvement in pain intensity. However, further research is necessary to confirm these results before definite recommendations can be made.

Effectiveness of individualized physiotherapy on pain and functioning compared to a standard exercise protocol in patients presenting with clinical signs of subacromial impingement syndrome. A randomized controlled trial.

BACKGROUND: Shoulder impingement syndrome is a common musculoskeletal complaint leading to significant reduction of health and disability. Physiotherapy is often the first choice of treatment although its effectiveness is still under debate. Systematic reviews in this field highlight the need for more high quality trials to investigate the effectiveness of physiotherapy interventions in patients with subacromial impingement syndrome. METHODS/DESIGN: This randomized controlled trial will investigate the effectiveness of individualized physiotherapy in patients presenting with clinical signs and symptoms of subacromial impingement, involving 90 participants aged 18-75. Participants are recruited from outpatient physiotherapy clinics, general practitioners, and orthopaedic surgeons in Germany. Eligible participants will be randomly allocated to either individualized physiotherapy or to a standard exercise protocol using central randomization. The control group will perform the standard exercise protocol aiming to restore muscular deficits in strength, mobility, and coordination of the rotator cuff and the shoulder girdle muscles to unload the subacromial space during active movements. Participants of the intervention group will perform the standard exercise protocol as a home program, and will additionally be treated with individualized physiotherapy based on clinical examination results, and guided by a decision tree. After the intervention phase both groups will continue their home program for another 7 weeks. Outcome will be measured at 5 weeks and at 3 and 12 months after inclusion using the shoulder pain and disability index and patients' global impression of change, the generic patient-specific scale, the average weekly pain score, and patient satisfaction with treatment. Additionally, the fear avoidance beliefs questionnaire, the pain catastrophizing scale, and patients' expectancies of treatment effect are assessed. Participants' adherence to the protocol, use of additional treatments for the shoulder, direct and indirect costs, and sick leave due to shoulder complaints will be recorded in a shoulder log-book. DISCUSSION: To our knowledge this is the first trial comparing individualized physiotherapy based on a defined decision making process to a standardized exercise protocol. Using high-quality methodologies, this trial will add evidence to the limited body of knowledge about the effect of physiotherapy in patients with SIS.

Effects of physiotherapy in patients with shoulder impingement syndrome: a systematic review of the literature.

OBJECTIVE: To critically summarize the effectiveness of physio-therapy in patients presenting clinical signs of shoulder impingement syndrome. DESIGN: Systematic review. METHODS: Randomized controlled trials were searched electronically and manually from 1966 to December 2007. Study quality was independently assessed by 2 reviewers using the Physiotherapy Evidence Database (PEDro) scale. If possible, relative risks and weighted mean differences were calculated for individual studies, and relative risks or standardized mean differences for pooled data, otherwise results were summarized in a best evidence synthesis. RESULTS: Sixteen studies were included, with a mean quality score of 6.8 points out of 10. Many different diagnostic criteria for shoulder impingement syndrome were applied. Physio-therapist-led exercises and surgery were equally effective treatments for shoulder impingement syndrome in the long term. Also, home-based exercises were as effective as combined physiotherapy interventions. Adding manual therapy to exercise programmes may have an additional benefit on pain at 3 weeks follow-up. Moderate evidence exists that passive treatments are not effective and cannot be justified. CONCLUSION: This review shows an equal effectiveness of physiotherapist-led exercises compared with surgery in the long term and of home-based exercises compared with combined physiotherapy interventions in patients with shoulder impingement syndrome in the short and long term; passive treatments cannot be recommended for shoulder impingement syndrome. However, in general, the samples were small, and different diagnostic criteria were applied, which makes a firm conclusion difficult. More high-quality trials with longer follow-ups are recommended.
