Detailed Description

Subacromial impingement syndrome is a common cause of shoulder pain. Although exercise therapy is effective, clinical outcomes remain suboptimal. An AI-based digital rehabilitation system can monitor patients' home exercise movements in real time and provide feedback. This study will enroll 93 patients with SIS, who will be allocated by preference into three groups: control (home exercise prescription only), traditional rehabilitation (manual therapy + daily home exercises for 8 weeks), and AI-based rehabilitation (in-clinic sessions + AI-powered home training with remote supervision for 8 weeks). The primary outcome is CMS; secondary outcomes include VAS, active shoulder range of motion, and functional movement assessment. Follow-up occurs at baseline, 4 weeks, 8 weeks, and 1, 2, and 3 months post-intervention.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Traditional Rehabilitation Group
Patients receive in-clinic manual therapy (joint and soft tissue mobilization) twice weekly, plus daily home-based shoulder functional exercises (including ROM, flexibility, rotator cuff and scapular stabilizer strengthening) for 40 minutes per session, lasting 8 weeks.
Other: Traditional Rehabilitation Training
Patients receive in-clinic manual therapy (joint and soft tissue mobilization) twice weekly, plus daily home-based shoulder functional exercises (including ROM, flexibility, rotator cuff and scapular stabilizer strengthening) for 40 minutes per session, lasting 8 weeks.
Experimental: AI-based Rehabilitation Group
Patients receive in-clinic rehabilitation sessions twice weekly (same content as traditional group) and perform daily home training (40 minutes/day for 8 weeks) using the "ShuKangShi" AI digital rehabilitation system.
Other: Home-based Rehabilitation Training Combined with Intelligent Rehabilitation Training
Patients receive in-clinic rehabilitation sessions twice weekly (same content as traditional group) and perform daily home training (40 minutes/day for 8 weeks) using the "ShuKangShi" AI digital rehabilitation system.
Experimental: Control Group
After diagnosis, patients in this arm receive only a home exercise prescription without additional active rehabilitation guidance or manual therapy.
Other: Prescribe home-based rehabilitation prescriptions for home rehabilitation training
After diagnosis, patients in this arm receive only a home exercise prescription without additional active rehabilitation guidance or manual therapy. They perform prescribed home exercises on their own ,Only regular follow-up assessments are conducted (baseline, 4 weeks, 8 weeks, and 1, 2, 3 months post-intervention).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Constant-Murley Shoulder Assessment Scale(CMS)
Time Frame: baseline, 4 weeks, 8 weeks ,1 month,2 month,3 month
he Constant-Murley Shoulder Score (CMS) is used to assess overall shoulder function. As the gold-standard tool for rehabilitation evaluation of rotator cuff injuries, this scale integrates subjective and objective assessments, covering four dimensions: pain (15 points), activities of daily living (20 points), active range of motion (40 points), and muscle strength (25 points), with a total score of 100 points. Scoring criteria: excellent for 80-100 points, good for 70-79 points, fair for 60-69 points, and poor for scores below 60 points.
baseline, 4 weeks, 8 weeks ,1 month,2 month,3 month

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visual Analogue Scale（VAS）
Time Frame: Baseline，0 week，4 week，8 week，1 month ，2 month， 3 month
The Visual Analogue Scale (VAS) is used to evaluate shoulder pain severity. As a common tool for clinical pain assessment, it uses a 100-mm sliding scale with 0 points representing no pain at one end and 10 points representing the most severe pain at the other end. Patients mark the corresponding position on the scale according to their pain perception; higher scores indicate more severe pain.
Baseline，0 week，4 week，8 week，1 month ，2 month， 3 month
Active Range of Motion of the Shoulder-Forward Flexion
Time Frame: Baseline, Week 0, Week 4, Week 8, 1 month, 2 months, 3 months
Measured using a goniometer. The patient actively performs shoulder forward flexion. The range of motion is measured in degrees (°). A larger angle indicates better shoulder mobility.

Active Range of Motion of the Shoulder - Extension
Time Frame: baseline, 0 week, 4 weeks, 8 weeks, 1 month, 2 months, 3 months

Active Range of Motion of the Shoulder - External Rotation
Time Frame: baseline, 0 week, 4 weeks, 8 weeks, 1 month, 2 months, 3 months
