- During a course of treatment, compared to other exercises, eccentric exercises provide a very small, short term, reduction in pain and no change in function.
BACKGROUND & OBJECTIVE
Systematic reviews of exercise interventions for subacromial impingement syndrome or rotator cuff related shoulder pain (1) indicate that exercise is effective in reducing pain and increasing function (2,3). However, the most effective form of exercise is unknown (2,3). Eccentric exercises, performed when muscles actively lengthen, are commonly used for tendon related pain in other regions, albeit with varying effectiveness (4,5). The authors of this study conducted a systematic review to investigate the effectiveness of eccentric exercise compared with other exercises or interventions on reducing pain and increasing function for people with a clinical diagnosis of “subacromial impingement syndrome”.
If prescribing eccentric exercises, monitor pain reduction closely, progressing loading and integrating goal-specific or functional exercises once progress plateaus.
