Selective Activation of the Infraspinatus During External Rotation Exercises in Participants With Rounded Shoulder Posture

The purpose of this prospective, cross-sectional study was to evaluate the selective activation of the infraspinatus during external rotation exercises in participants with rounded shoulder postures and compare the different exercise positions. The fifteen (7 males and 8 females) participants with rounded shoulder posture were recruited for this study. The EMG activations of the middle trapezius, posterior deltoid and infraspinatus muscles in the dominant limb were recorded during exercises in standing external rotation (SER), side-lying position (SDER), scapular plane (SPER) and muscle architecture-based (MABER) positions.
