Some parameters of amplitude, duration, area, conduction velocity, etc, has been used in nerve conduction studies to evaluate nerve functions.

Analysis of the parameters, amplitude, duration and area, of muscle action potentials(MAPS) was done in healthy sixteen men and four women and used median, ulnar, peroneal, and tibial nerves of dominant side.

The amplitudes and areas of MAPS by stimulation at distal were increased, but the durations were decreased campared with those of proximal stimulation. But the differences between distal and proximal stimulation were not significant statistically. The duration was a parameter having most narrow variation among individuals.

And there is a highly significant correlationship(p<0.05) between amplitude and area in the 4 nerves, statistically.

Key Words: Muscle action potential, Amplitude, Duration, Area
