Summary

This study aims to investigate the effects of performing the Bilateral Scapular Retraction with Shoulder External Rotation (BSR-SER) exercise under kinetic chain involvement and unstable surface conditions on trapezius muscle activation. Surface electromyography (EMG) will be used to assess the activity levels of the upper, middle, and lower trapezius muscles. The goal is to determine whether integrating kinetic chain elements and instability can optimize muscle activation patterns in healthy individuals during a commonly used scapular rehabilitation exercise.

BEHAVIORAL

Bilateral Scapular Retraction with Shoulder External Rotation (BSR-SER) Exercise

Participants perform the Bilateral Scapular Retraction with Shoulder External Rotation (BSR-SER) exercise using a resistance band. The exercise is conducted under various conditions including stable and unstable surfaces (using BOSU® balance trainer) and in three different lower limb positions: standing, lunge, and squat. Each condition is randomized, and participants complete all conditions in a crossover design. The intervention aims to evaluate trapezius muscle activation patterns during these exercises using surface electromyography (EMG).
