Brief Summary

With this study it will determined that the effect of critical shoulder angle which will be obtained from the MRI images of patients with Subacromial Impingement Syndrome on proprioception and disability level.

Detailed Description

Critical shoulder angle (CSA) is defined as the intersection angle between two lines which are drawn from inferior border of glenoid cavity to superior border of glenoid cavity and from inferior border of glenoid cavity to inferolateral border of acromion. Higher CSA is accepted a predisposing factor for degenerative shoulder diseases. Increase in CSA means more shear forces reflects on shoulder joint which also causes overload on the RC tendon. Increase of degeneration in shoulder joint may cause decreased proprioception. As a result of degeneration, the level of disability will be increased. At the end of this study, the relationship among critical shoulder angle, proprioception and disability could be more clearly interpreted.
