Karagiannakis D, et al. - This trial encompassed the determination of the possible alterations in the activation of periscapular muscles of healthy female volleyball players with scapular asymmetry, in the resting position. There did not appear to be any impact on the EMG activity of periscapular muscles (serratus anterior (SA), upper trapezius (UT) and middle trapezius (MT)) during the execution of a close chain exercise in the study cohort, with the scapula of the dominant side in a more protracted and depressed resting position.
