Hacettepe University
27 participants

INTERVENTIONAL
Conditions
Summary
Postoperative rehabilitation after reverse shoulder arthroplasty aims to improve pain control, range of motion, and functional capacity. However, studies examining the effects of strengthening exercises targeting the humeral head depressor muscles are limited. This randomized controlled trial will evaluate the effects of adding a specific strengthening program to standard rehabilitation on pain, range of motion, quality of life, and functional outcomes.
Eligibility
Inclusion Criteria1

Exclusion Criteria1
- Active infection Deltoid muscle insufficiency Inability or unwillingness to comply with randomization Prior shoulder arthroplasty on the same side Unwillingness to participate Inability to read or understand written instructions

Interventions
After randomization and baseline assessments, participants will undergo a standard 6-week postoperative shoulder rehabilitation program, consisting of range-of-motion exercises, scapular stabilization training, and progressive strengthening. No additional depressor muscle-specific exercises will be applied.
After randomization and baseline assessments, participants will receive a 6-week rehabilitation program consisting of conventional postoperative shoulder rehabilitation combined with a specific strengthening protocol targeting the shoulder depressor muscles.
