CONCLUSIONS - Relation between preoperative electromyographic activity of the deltoid and trape

Postoperative shoulder strength after RSA was increased in patients with greater preoperative EMG activity in the middle deltoid and upper trapezius. Preoperative EMG activity of the anterior or middle deltoid muscle was associated with active ROM of flexion or abduction, while EMG activity of the posterior deltoid was associated with the active ROM of external rotation. Therefore, preoperative EMG measurements of these muscles will help to predict the postoperative outcome of RSA and set reasonable post-surgical patient expectations in the preoperative setting.
