Establishment of normative value of multiple segments motor nerve conduction velocity of bilateral median nerve and ulnar nerve / 中国康复医学杂志

ABSTRACT

Objective: To establish normative value of multiple segments motor nerve conduction of bilateral median nerve and ulnar nerve, including motor nerve conduction velocity (MCV)、latency (LAT)and amplitude (AMP). Method: Two hundred normal volunteers were divided into 5 groups according to different ages. Median nerve was examined at multiple points palm, wrist, elbow, axilla and Erb's. Ulnar nerve was examined at multiple points wrist, below elbow, above elbow, axilla and Erb's. The values of segmental MCV, LAT and AMP were recorded. Result: Gender and sidedness had no effect on MCV, LAT and AMP of median nerve and ulnar nerve. However, age had significant effects on MCV, LAT and AMP of median nerve and AMP of ulnar nerve. Conclusion: The examination of multiple segments motor nerve conduction of bilateral median nerve and ulnar nerve possess important value in diagnosis.
