NORMAL FINDINGS OF MEDIAN NERVE COUDUCTION STUDY IN SINA HOSPITAL

Abstract

Because of high prevalence of upper limbs pain and carpal tunnel sndrome and the need of proofing of diagnosis by nerve conduction study (NCS) testing of edian nerve is one of the most common exams in electro-diagnostic centers. In interpretation of findings of nerve conduction study; presence of a normal range for findings is one of the most important points."nMaterials and Methods: In this study we obtained the findings of nerve conduction study of median nerve in 60 normal persons."nResults: The mean of motor distal latency was 3.09 ms (SD: 0.35). The mean of sensory distal latency measured to peak of response was 3.04 ms (SD: 0.28) with increasing age; mean of motor and sensory distal latencies increased. Most of findings had no significant difference with other references."nConclusion: There is no problem in using of the normal ranges of the other countries for Iranian patients.
