Subscapularis Strength After Total Shoulder Arthroplasty

Subscapularis Strength After Total Shoulder Arthroplasty

This is a randomized, double-blinded, standard of care-controlled clinical trial. The purpose of this study is to determine the difference in subscapularis strength and function after anatomic Total Shoulder Arthroplasty (aTSA) in patients who receive isolated subscapularis rehabilitation in addition to the standard rehabilitation after surgery at 12-month follow up. Specifically the investigators will measure subscapularis strength utilizing a dynamometer device and subscapularis function utilizing isolated subscapularis physical examination testing: belly-press, bear-hug, and lift-off tests. Additionally, investigators will document secondary outcome measures including shoulder range of motion and Patient Reported Outcome Measure Information System (PROMIS) questionnaire scores.
