Subacromial Impingement Syndrome (SIS) is characterized by abnormal scapular motion, including decreased upward rotation, increased internal rotation, and excessive anterior tilting, which impair shoulder and arm function. Integrated scapular rehabilitation combines Instrument-Assisted Soft Tissue Mobilization (IASTM) and postural correction exercises. IASTM detects soft tissue restrictions through multidirectional strokes and enhances the pain threshold of myofascial trigger points (MTrPs) via reflex hyperemia. Postural correction exercises aim to strengthen weakened muscles and stretch tight ones to improve stability and posture. The combination of these interventions may enhance scapular stability and dynamic control. This study aimed to investigate the effects of integrated scapular rehabilitation on scapular kinematics, movement correction, functional improvement, and pain management in tennis athletes with SIS. A two-way repeated-measures ANOVA was used to analyze pre- and post-intervention effects.

Pain (VAS score during the Hawkins test)
Timeframe: Participants were assessed at time points: prior to the intervention (baseline), immediately three weeks after the intervention, and at a one-month follow-up.
