Comparison of median nerve conduction parameters from the index and middle fingers in carpal tunnel syndrome: Toward a standardized electrophysiological evaluation protocol

Key Points

• To evaluate the effectiveness of middle finger peak latency and interdigit latency in diagnosing carpal tunnel syndrome (CTS).
• Comparison of median nerve conduction parameters from index and middle fingers
• Assessment of peak latency and interdigit latency
• Analysis of standard electrodiagnostic protocols
• Middle finger peak latency showed superior diagnostic value over index finger recordings.
• Incorporating middle finger peak latency improved early detection of CTS.
• Interdigit latency differences contributed to better classification of the syndrome.
