Abstract

Abstract
Background: A loss of glenohumeral internal rotation has been associated with altered kinematics of the glenohumeral and the scapulothoracic joint.
Aim of Study: To evaluate the association between Ac-romio-humeral distance (AHD), gleno-humeral internal rotation deficit GIRD).
Methods: 40 impingement patients (from 25 to 45 years old), participated in this study,They were evaluated by ultra-sonography for acromio-humeral distance(AHD), digital goniometer for gleno-humeral internal rotation deficit (GIRD).
Results: This study showed a positive significant relation between gleno-humeral internal rotation difict (GIRD) and acromio-humeral distance (AHD), GIRD increase, AHD decrease.
Conclusion: Glenohumeral internal rotation deficit, de-crease acromiohumeral distance and lead to compression of the rotator cuff and subacromial bursa in this limited space in patients with shoulder impingement syndrome.
