Evaluation of the scratch collapse test in peroneal nerve compression.
Plast Reconstr Surg. 2011 Oct; 128(4):933-9.PR

Abstract

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.
