The atrophy of the muscles of foot is generally observed in case of flat-foot. But how can it be testified by means of electromyographic impression, and what form of impression do the muscles show?
I have examined the clectromgogram of musculus abductor hallucis and musculus flexor hallucis longus in standing position, by means of the measurement of the electric discharge of the neuromuscular unit.
The results obtained are as follows:
1) The sway of the discharge intervals of the neuromuscular unit of the flat-foot is wider than of the normal one.
2) The discharge intervals in case of the flat-foot are shorter than those of the normal one.
These results, I suppose, reveal the fact that the foot muscles of the flat-foot patients should more easily be tired than those of normal ones.
