The scratch collapse test is a recently described provocative test for diagnosis of peripheral nerve compression.
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.
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.
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.
CLINICAL QUESTION/LEVEL OF EVIDENCE: Diagnostic, II.
划痕塌陷试验是一种最近描述的用于诊断周围神经压迫的激发试验。
本研究前瞻性地研究了 24 例连续诊断为腓总神经压迫神经病的患者。通过病史、体格检查和电诊断检查来确诊。对划痕塌陷试验和 Tinel 征进行激发性检测。
划痕塌陷试验的敏感性为 0.77，特异性为 0.99，而 Tinel 征的敏感性和特异性分别为 0.65 和 0.99。
划痕塌陷试验是一种敏感和特异的激发试验，与现有临床检查相比具有优势，有助于诊断腓总神经病。
临床问题/证据水平：诊断，II 级。
