Self-managed loaded exercise versus usual physiotherapy treatment for rotator cuff tendinopathy: a pilot randomised controlled trial

Objectives Rotator cuff tendinopathy is a common source of shoulder pain characterised by persistent and/or recurrent problems for a proportion of sufferers. The aim of this study was to pilot the methods proposed to conduct a substantive study to evaluate the effectiveness of a self-managed loaded exercise programme versus usual physiotherapy treatment for rotator cuff tendinopathy. Design A single-centre pragmatic unblinded parallel group pilot randomised controlled trial. Setting One private physiotherapy clinic, northern England. Participants Twenty-four participants with rotator cuff tendinopathy. Interventions The intervention was a programme of self-managed loaded exercise. The control group received usual physiotherapy treatment. Main outcomes Baseline assessment comprised the Shoulder Pain and Disability Index (SPADI) and the Short-Form 36, repeated three months post randomisation. Results The recruitment target was met and the majority of participants (98%) were willing to be randomised. 100% retention was attained with all participants completing the SPADI at three months. Exercise adherence rates were excellent (90%). The mean change in SPADI score was 23.7 (95% CI 14.4 to 33.3) points for the self-managed exercise group and 19.0 (95% CI 6.0 to 31.9) points for the usual physiotherapy treatment group. The difference in three month SPADI scores was 0.1(95% CI 16.6 to 16.9) points in favour of the usual physiotherapy treatment group. Conclusions In keeping with previous research which indicates the need for further evaluation of self-managed loaded exercise for rotator cuff tendinopathy, these methods and the preliminary evaluation of outcome offer a foundation and stimulus to conduct a substantive study.
