title: Clinical efficacy of electroneurometer screening in carpal tunnel syndrome.
abstract: The authors evaluated the motor latency values of 72 median nerves assessed with the compact, hand-held, battery-powered NervePace Electroneurometer. Results of this test were compared to those of clinical examination, standard electrodiagnostic tests, and median nerve findings of compression at the time of surgery in 23 patients. The motor latency values obtained with an electroneurometer correlated positively with those from routine electromyography (EMG): sensitivity and specificity were calculated for the ability to diagnose carpal tunnel syndrome (CTS) (> 3.9 ms considered abnormal). This study identified a sensitivity of 85.7% and a specificity of 87.5% in predicting CTS, as confirmed by complete EMG and electroconduction studies.
