Abstract

Background Research has shown loaded exercise to be beneficial for patients with rotator cuff related shoulder pain in terms of improving shoulder function, self-reported disability and pain1,2. The optimal duration for which these patients should complete a loaded exercise programme to achieve beneficial effects remains unclear. Objectives The purpose of this study is to determine if 6 weeks of a supervised shoulder specific exercise programme is as effective as 12 weeks of the same programme, for improving shoulder function, self-reported disability and pain, in patients with rotator cuff related shoulder pain. Methods In this randomised controlled single-blinded study patients with a history of lateral upper arm pain with MRI confirmation of rotator cuff pathology or positive testing on a cluster of clinical rotator cuff tests were included. Patients with a recent history of shoulder surgery or a shoulder fracture were excluded. Participants were randomly assigned to complete either 6 weeks (short group) or 12 weeks (long group) of the exercise programme. Both groups performed the same specific set of loaded exercises daily at home and attended 6 clinic-based group exercise sessions2. Participants were assessed at 6 weeks, 3 and 6 months. Shoulder function was assessed using the Constant-Murley (CM) score. Disability was assessed using the QuickDash and the Shoulder Pain and Disability Index (SPADI). Pain was assessed using a visual analogue scale. Group comparisons were made using univariate generalised linear models. Results 85 patients were included in this study as per Table 1. Within each group shoulder function, self-reported disability and pain improved significantly at 3 months (p Conclusion In the management of patients with rotator cuff related shoulder pain the findings of this study indicate that a 12 week exercise programme results in better outcomes for pain at 3 months and self-disability and shoulder function at 6 months.
