Effects of Myofascial Chain Tension Modulation Combined With Scapular Corrective Exercise on Scapular Movement Performance and Functional Outcomes in Tennis Players With Subacromial Impingement Syndrome

36 participantsStarted 2026-02-01

Plain-language summary

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.

Inclusion criteria

. a VAS score greater than 3 during the Hawkins test (indicating mild to moderate pain),
. at least two positive results among the Hawkins test, Neer test, and painful arch test, and
. a positive result on the mSAT. Only participants who fulfilled all three criteria were enrolled in the study.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

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.
