About this study

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.

Other names: Evaluation of Critical Shoulder Angle, Evaluation of Shoulder Proprioception, Evaluation of Shoulder Disability

Primary outcomes

  1. 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.

Secondary outcomes

  1. 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.

  2. 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.
