Shoulder and trunk movement and muscle activity during the tennis serve in players with shoulder pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study will recruit about 60 amateur tennis players who train at least 4 hours per week and have an NTRP level of 3.5 or higher. Participants will undergo motion-capture and surface electromyography (EMG) while performing tennis serves to measure shoulder and trunk kinematics and shoulder muscle activation, together with clinical musculoskeletal measurements. Players with subacromial pain syndrome or a history of shoulder pain will be compared to players without such pain to identify movement or activation patterns linked to pain. Exclusion criteria include prior shoulder surgery, recent major trauma, or any current injury that prevents full-skill serving.
