Purpose[edit | edit source]
The scarf test, also known as the cross-body adduction test, is used to assess the integrity of the acromioclavicular (AC) joint.
Technique[edit | edit source]
The test is performed by passively bringing the patient's arm into 90 degrees of forward flexion, with their elbow also flexed to 90 degrees. The examiner then horizontally adducts the flexed arm across the patient's body [1].
This position results in compression of the medial acromial facet against the distal clavicle to provoke symptoms at the acromioclavicular joint [1].
Interpretation[edit | edit source]
This test is considered positive if the maneuver successfully reproduces the patient's symptoms of pain localized over the AC joint, suggestive of AC joint pathology [1].
Validity[edit | edit source]
- Sensitivity = 0.23
- Specificity = 0.82
- +LR = 1.25 / -LR = 0.95
