About this study
Official title: 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.
Read the 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Critical Shoulder Angle
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.
Measured: Baseline (The evaluation will be conducted only once)
Secondary outcomes (2)
Shoulder Proprioception
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.
Measured: Baseline (The evaluation will be conducted only once)
Disability
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.
Measured: Baseline (The evaluation will be conducted only once)

What does the primary outcome measure?
Critical Shoulder Angle (time frame: Baseline (The evaluation will be conducted only once)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2026.
