Concentric vs Eccentric Full Can Exercise for Partial Rotator Cuff Tears

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, assessor-blinded trial compares two contraction types of the full can exercise added to a standard physiotherapy program for adults with partial supraspinatus tears. Participants are randomly assigned to concentric (lifting) or eccentric (lowering) emphasis over six weeks, with outcomes assessed by a blinded evaluator. All participants receive usual care such as ultrasound, TENS, and rehabilitation exercises three times per week. The study aims to clarify which contraction style better preserves or enhances supraspinatus architecture and clinical outcomes. Recruitment is at Firat University and Fethi Sekin City Hospital in Elazığ, Turkey.
