Does Undergoing a Prehabilitation Protocol Aimed at Optimizing Scapulothoracic Mobility and Strengthening Improve Internal Rotation After Reverse Shoulder Arthroplasty?

Difficulty with internal rotation (IR) after reverse shoulder arthroplasty (RSA) is common. Current rehabilitation protocols may not optimize IR. The investigator's objective is to assess the impact of prehabilitation focused on IR strengthening and mobility on RSA outcomes. The investigators will perform a prospective, randomized control trial to achieve the specific aim: assessing range of motion, strength, patient-reported outcomes, and activities of daily living requiring internal rotation between control and prehabilitation cohorts, with the prehabilitation patients receiving 6 weeks of treatment.
