Study of Motor Nerve Conduction of Normal Radial Nerve

Abstract
|
|
|
The radial nerve is one of the most freqeuntly injured nerves and the clinical localization is not always clear.
Determination of motor nerve conduction velocity of the radial nerve is more difficult than the median or ulnar nerve in upper extremity because of anatomic characteristics.
The present study has been undertaken to determine the normal range of proximal and distal motor nerve conduction velocity of radial nerve by jebsei´s method.
Fifty one healthy Korean subjects (thirty male and twenty one female) were examine. Their ages ranged .14 to 68 in years.
The results obtained were as follows
1. Mean value for the distal motor nerve conduction velocity of radial nerve was 58.9± 5.3m/sec, respectively.
2. Mean value for the proximal motor nerve conduction velocity of xadial nerve was 63. ,6±6. im/sec, respectively.
3. Mean values for the dital latency, middle latency, proximal latency were 2.03±0.32 msec, 5.78±0.61´ msec, respectively.
4. In motor nerve conduction velocity or distal latency, no significant difference were observed between male and female or right and left side.
5. Motor nerve conduction velocity of radial nerve was slow after fifth decade.
6. In motor nerve conduction velocity, there´s no significant difference between radial nerve and median or ulnar nerve.
