Shockwave therapy associated with progressive exercises in rotator cuff tendinopathy: a clinical trial protocol.

The aim of the present study is to determine whether adding shockwave therapy (SWT) to a progressive exercise program improves shoulder pain and function in individuals with rotator cuff tendinopathy (RC tendinopathy). Ninety patients diagnosed with rotator cuff tendinopathy will be randomly allocated into two groups: active SWT plus a progressive exercise program or placebo SWT plus a progressive exercise program. Primary outcomes will be measured using the Constant-Murley Score function questionnaire and by assessing patient-reported pain intensity with the numerical pain rating scale. The secondary outcomes will be measured using the Global Perceived Effects Scale and Shoulder Pain and Disability Index. All the outcomes will be measured immediately after the end of treatment and at 3-month follow-up.
