CTS is the most common entrapment neuropathy of the upper limb, caused by compression of the median nerve at the wrist. It's often linked to repetitive hand movements, prolonged wrist flexion, pregnancy, diabetes, and other conditions. We'll show you how to perform the scratch collapse test step-by-step: 1. Patient in standing or sitting position with arms in anatomical position, elbows flexed to 90 degrees, and hands outstretched. 2. Apply bilateral resisted external rotation at the distal forearm. 3. Scratch or swipe over the median nerve at the wrist. 4. Immediately repeat the resisted external rotation test. A positive test is indicated by a brief loss of external rotation strength following the scratch stimulus. The scratch collapse test was originally proposed by Cheng et al. (2008), who reported a sensitivity of 64% and specificity of 99%. However, a 2023 meta-analysis by Jain et al. reported a pooled sensitivity of 29.4% and specificity of 90.4% compared to electrodiagnostic tests. While the test has high specificity, it has limited sensitivity. Its pooled statistical values render its clinical value strong for confirming the presence of carpal tunnel syndrome.
