This 2009 systematic review by Kuhn evaluates 11 RCTs (level 1–2 evidence) to determine what exercise actually achieves in rotator cuff impingement and to synthesize their protocols into a single evidence-based rehabilitation program for use in future research.
When prescribing conservative treatment for impingement, set realistic expectations — exercise reliably reduces pain and improves function but will not restore strength or ROM on its own, so add manual therapy early and structure a home program the patient can sustain, knowing roughly 1 in 5 will still require surgery within 2–3 years.
