The Relationship of Critical Shoulder Angle With Proprioception and Disability in Patients With Subacromial Impingement

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Critical Shoulder Angle
Time Frame: Baseline (The evaluation will be conducted only once)
Critical Shoulder Angle is 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. That will be measured from the MRI images of patients.
Baseline (The evaluation will be conducted only once)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Disability
Time Frame: Baseline (The evaluation will be conducted only once)
The disability will be assessed by using SPADI (Shoulder Pain and disability Index). First part includes 5 questions inquiring pain status. Second part includes 8 questions inquiring activity participation status. Total score ranges between 0-100. Increase of scores reflects higher disability.
Baseline (The evaluation will be conducted only once)
Shoulder Proprioception
Time Frame: Baseline (The evaluation will be conducted only once)

Shoulder proprioception will be evaluated 60° ve 90° ve 120° degrees of shoulder joint active-active, active-passive and passive-active manner.

The Shoulder proprioception will be assessed using a bubble inclinometer.
Baseline (The evaluation will be conducted only once)
