BACKGROUND: The scratch collapse test is a recently described provocative test for diagnosis of peripheral nerve compression. METHODS: The scratch collapse test was studied prospectively in 24 consecutive patients with a diagnosis of common peroneal nerve compression neuropathy. The diagnosis was confirmed by history, physical examination, and electrodiagnostic testing. Provocative testing by the scratch collapse test and Tinel's sign was performed. RESULTS: The scratch collapse test showed a sensitivity of 0.77 and a specificity of 0.99, while the Tinel's sign showed 0.65 and 0.99, respectively. CONCLUSION: The scratch collapse test is a sensitive and specific provocative test that compares favorably to existing clinical tests and aids in the diagnosis of common peroneal neuropathy.
