Abstract
When a thenar muscle is performing a maximum isometric contraction and supramaximal stimulus is applied to median nerve, there is a silent period (pause in electrical activity) in the electromyogram(EMG).
In this paper, a new model of EMG-signal generation including silent period in thenar muscle is proposed. This work was based on anatomical structure of spinal nerve system and characteristics of neuro-physiological data that are related on carpal tunnel syndrome. Also in this paper, to obtain real EMG-signal including silent period from normal subjects without neurological alterations and carpal tunnel syndrome patients.
As a result, if there is the symptom of carpal tunnel syndrome, the EMG-signal, the summation of silent period is in normal silent period. It is possible to see that the summation of silent period is long as the symptom of carpal tunnel syndrome is severe and that there is correlation between carpal tunnel syndrome and silent period.
