The purposes of this study were to compare the effects of flexed head positions on scapular orientation and muscle activity during humeral elevation, and to determine any association of kinematic and electromyographic (EMG) responses. Note: Peak humeral elevation of tasks A to D was summation of peak scapular upward rotation and peak humeral elevation relative to scapula. Another great shoulder elevation stretch is a variation on the simple shrug. Force Couples of The Shoulder: Rotator Cuff Anterior-Posterior.

Significantly higher coordination existed between the rotator cuff and deltoid muscle groups during the initial (Pearson Correlation Coefficient (PCC) = 0.79) and final (PCC = 0.74) stages of shoulder elevation compared to the mid-range (PCC = 0.34) (p = 0.020-0.035). The Mauchly test revealed that the data for scapular ER violated the assumption of sphericity for the effects of both shoulder elevation (P = .01) and elbow position (P < .001). a) scapular winging. Standing active forward elevation produced the highest maximal levels of muscle activation. No shoulder elevation by elbow position interaction was seen for scapular ER (F 28,420 = 1.26, P = .30; Figure 6). Anterior Shoulder Raises. Back.
