Abstract
Aim: This study proposed to detect sensitivity of different electrophysiological techniques in early diagnosis of Carpal Tunnel Syndrome (CTS) compared to the standard technique as Median Sensory Latency.

Methods and Instrument: The present study included 70 hands (40 hands with clinical evidence of idiopathic CTS and 30 hands as control group). The following tests were done for both groups: 1- Sensory nerve conduction study: median nerve, ulnar nerve, median versus ulnar latency difference between second and fifth digits, median versus ulnar latency difference (ring finger) 2- Motor nerve conduction study: median nerve, ulnar nerve, median versus ulnar motor latency difference.

Findings: The most sensitive (92%) two tests were median-ulnar sensory latency difference recorded from second and fifth digits and median-ulnar sensory latency difference recorded from fourth digit, while median-ulnar motor latency difference and median motor latency showed lowest sensitivity (61, 53%) respectively.

Conclusion: Median-ulnar sensory latency difference recorded from digit two and digit five and that recorded from digit 4 have highest sensitivity for early detection of CTS.
