Abstract

Thirty eight patients with carpal tunnel syndrome were studied about the electrodiagnositc aspects at Srinagarind Hospital. The patients were 32 females and 6 males , age range 32-71 years old. Sixty nine median nerves were abnormal showed : 1. Sensory distal latencies are 3.6-6.8 msec., all have normal sensory nerve conduction velocity (NCV) except 2. Motor distal latencies are abnormal 63% and abnormal motor NCV 12% 3. Sensory distal latencies have the relation to the motor distal latencies significantly and can calculate m = 1.0655s – 0.024 (m = Motor distal latency . s = Sensory distal (latency) 4. Electromyography (EMG) of  the abductor pollicis brevis are abnormal 20% . The involvement of the ulnar nerves are found only abnormal sensory distal latency  7%
