简要总结
This randomized controlled study aims to evaluate the effects of scapular stabilization exercises on pain, shoulder function, and quality of life in patients with subacromial impingement syndrome. Participants will be randomly assigned to either a scapular stabilization exercise program or a conventional shoulder rehabilitation program. Pain, functional outcome measures, and patient-reported quality of life will be assessed at baseline, 4 weeks, and 12 weeks. The study seeks to determine whether adding scapular stabilization exercises provides superior clinical benefit.
详细描述
Subacromial impingement syndrome (SIS) is one of the most common causes of shoulder pain and functional limitation. Scapular dyskinesis plays a key role in the development and persistence of SIS by altering scapulohumeral rhythm and increasing mechanical stress on subacromial tissues. Scapular stabilization exercises are increasingly used to restore normal scapular mechanics, improve muscular control, and reduce pain, but the clinical effectiveness of these exercises compared to conventional rehabilitation programs remains unclear.
This prospective, single-blind randomized controlled study investigates the effects of a scapular stabilization exercise program on pain, functional outcomes, and quality of life in patients diagnosed with SIS. Participants are randomly allocated to either a scapular stabilization group or a conventional shoulder rehabilitation group. Pain (VAS), functional status (QuickDASH and SPADI), range of motion, and quality-of-life measures are assessed at baseline, 4 weeks, and 12 weeks. The study aims to determine whether adding scapular stabilization exercises to standard rehabilitation leads to superior clinical improvement compared to conventional therapy alone.

研究组 & 干预措施
Standard Physiotherapy
Participants in this arm receive standard physiotherapy consisting of electrotherapy, range-of-motion exercises, and stretching. The program is administered three times per week for 12 weeks. No scapular-specific stabilization or mobilization exercises are included. All participants also receive a home exercise program for daily stretching and mobility exercises.
干预措施: Standard Physiotherapy (Other)
Scapular Stabilization + Mobilization-Based Rehabilitation
Participants receive the same standard physiotherapy as the control group, combined with a supervised scapular stabilization and mobilization-based rehabilitation program. This structured 12-week protocol (3 sessions per week) includes passive scapular mobilization (10-12 minutes per session) and a three-phase stabilization exercise progression targeting scapular mechanics, muscle activation, strength, and neuromuscular control. A daily home exercise program is also provided.

结局指标
主要结局
1. Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) Score
时间窗: Baseline, Week 6, Week 12
QuickDASH is an 11-item validated questionnaire that measures physical function and symptoms related to upper extremity disorders. Total scores range from 0 to 100, with higher scores indicating greater disability. The primary outcome is the change in QuickDASH score from baseline to Week 12.
次要结局
- Modified Constant-Murley Score (CMS)(Baseline, Week 6, Week 12)
- Visual Analog Scale (VAS)(Baseline, Week 6, Week 12)
