Purpose
[edit | edit source]
The Clunk Test is used to identify a superior anterior and posterior glenoid labral tear of the shoulder joint.
Technique[1][2][edit | edit source]
- The patient lies in supine position with affected shoulder slightly over the edge of the bed.
- The examiner places one hand on the posterior aspect of the GH joint while the other hand holds the bicondylar aspect of the humerus above the elbow.
- the examiner then fully abducts the arm over the patient's head while pushing anteriorly on the humeral head and simultaneously externally rotating the arm.
Outcome: A positive test is produced by the presence of a catch, snap, clunk, or grinding sound. It indicates a labral tear.[2]
Evidence[3][4][5][6][edit | edit source]
The sensitivity and specificity of the Clunk Test has been reported by only one study[3]. The study has shown Clunk Test to have a sensitivity of 0.440% and a specificity of 0.68%[3].
- Sensitivity (95% CI): 0.440
- Specificity (95% CI): 0.680
- +LR (95% CI): 1.4
- -LR (95% CI): 0.8
- Accuracy (%): 57.0
