This paper investigated on the electrophysiological aspects of masseter muscle in patients with progressive muscle dystropy.
These Findings were as follow:
From the electromyogram of masseter muscle obtained by surface electrodes, it was recognized that the muscle activity showed low amplitude action potential, prolonged interval of pulse occuring, low frequency component on EMG power spectrum, small integral count and prolonged duration of silent period.
From these findings, it was suggested that the muscle atrophy in masseter muscle according to partial disappear of muscle fiber was appeared similarly to skeltal muscles.
