In rTSA phase 3 rehab, what is the primary objective?

• A. Progress Deltoid Exercises
• B. Strengthen Infraspinatus
• C. Increase Subscapularis Endurance
• D. Improve Teres Minor Flexibility

Answer: (A)

In a reverse total shoulder arthroplasty, the mechanics shift so the deltoid becomes the main driver of arm elevation because the rotator cuff’s ability to lift the arm is altered by the prosthesis. Phase 3 rehab prioritizes safely loading and strengthening the deltoid to restore active elevation and functional use of the arm. This focus is essential because the prosthesis relies on the deltoid for elevation, while the other rotator cuff muscles (infraspinatus, teres minor, subscapularis) are not the primary elevators in this setup and may not contribute as reliably to strength gains at this stage. The emphasis is on progressive deltoid strengthening and functional tasks, with other muscle goals addressed as appropriate but not the main objective.
