J Occup Environ Med. 2000;42(4):398-409.

Study Design
• EMG Lab at Massachusetts General Hospital, Boston
• 150 Symptomatic Subjects
• DML & F-wave measurements were recorded by a neurologist and the NC-stat System

Key Results
• Correlation of the NC-stat DML to the neurologist DML was 0.94
• Sensitivity 86%; Specificity 90% for Carpal Tunnel Syndrome
• Diagnostic Accuracy of 0.96 (area under ROC curve) for Carpal Tunnel Syndrome as determined by a neurologist
