Mediam and Ulnar Nerves Conduction Study

บทคัดย่อ

The study of motor nerve conduction velocity, motor distal latency and sensory distal latency of the median and ulnar nerves was done in 500 Volumteers aged 20-30 yearold, The results were (1)s motor nerve conduction velocity of the mediam and ulnar nerves were 60.16 +3.82 and 64.31+4.14 m/sec, (2) motor and distal latency of the median and ulnar nerves were  3.14 +0.31 and 2.62+0.2 msec, (3) sensory distal latency of the mediam and ulnar nerves were 2.95+0.15 and 2.94+ 0.17 msec, (4) The differents of the motor distal latency between the mediam and ulnar nerves in the same arm were ≤ 1.5 msec, between right and left mediam nerves and between right and lift ulner nerves were ≤0.9 and 0.3 mesc, (5) The diferents of the sensory distal latency between the mediam and ulnar nerves in the same arm was ≤0.4 msec, between right and lift mediam nerves and between right and lift ulnar nerves were ≤ 0.4 and 0.5 msec respectively.
