Scapular Position and Orientation during Abduction, Flexion and Scapular Plane elevation Phase

Results: Scapular upward rotation during 30 , 60 , and 90 of abduction, and initial angle of scapular plane elevation were significantly different between groups (P < 0.05). Posterior tipping was significantly decreased in patients with SIS at the initial angle of flexion (P =0.015). Lateral translation at 90 , and 110 of abduction (P =0.015, and P=0.012, respectively) were lesser in patients .
