"University of Kashan, Kashan, Iran Ailin Talim Khani University of Social Welfare and Rehabilitation Sciences, Tehran, Iran Objectives: The purpose of this study was to compare scapular kinematics during elevation phase of abduction, flexion, and scapular plane elevation phase between fifteen persons with shoulder impingement syndrome (SIS) and thirteen persons without it . Keywords: Scapular kinematics, different humorous angles, shoulders movement planes Submitted: 5 January 2014 Accepted: 27 February 2014 Introduction Shoulder impingement syndrome (SIS) first was described subacromial bursitis (1), but knowledge in SIS pathology was greatly explained by Neer (2) and after by Hawkins (3), as an internal or external compression force on rotator cuff tendons, subacromial bursa, and long head of the biceps tendon under the subacromial arch during arm elevation (4). Several studies illustrated abnormal three dimensional (3-D) scapular kinematics in patients with SIS and put forth a decrease in the scapular upward rotation, and posterior tipping during arm elevation phase of abduction and scapular plane elevation (5, 7, 9, 10). Discussion This study had purposed to compare the scapular kinematics between persons with and without SIS and follow determining whether any group differences were dependent on shoulder movement planes and humerus angles of elevation. The results of this analysis showed significant differences in the scapular position and orientation among patients with SIS as compared to the healthy persons during arm elevation angles below 110˚ abduction and scapular plane elevation, especially upward rotation was significant difference between two groups."
