Abstract

A diagnostic test combining the sensitivity of the Semmes-Weinstein monofilament measurement and the specificity of the wrist flexion provocational test has been evaluated in a group of 21 patients (33 hands) with electrodiagnostically verified carpal tunnel syndrome and 30 asymptomatic hands (controls). Semmes-Weinstein monofilament testing consisted of several sensory threshold measurements obtained by the application of force-calibrated Semmes-Weinstein monofilaments to each digit in the hand with the wrist in neutral position. The quantitative provocational diagnostic test employed Semmes-Weinstein measurements obtained with the wrist both in the neutral and flexed positions. The sensitivity (82%) and specificity (86%) of the combined test were calculated. It was more sensitive and specific than the wrist flexion test alone and more specific than the Semmes-Weinstein sensibility test. The combined test is recommended as the most accurate and sensitive quantitative clinical test for median nerve compression evaluated by the authors to date.
