PROBLEM TO BE SOLVED: To provide a muscle state measurement sheet which is capable of quantitatively detecting the amplitude or frequency of an evoked mechanomyogram MMG and accurately evaluating the active state of a muscle.SOLUTION: As a pair of stimulation electrodes and a muscle sound sensor face the back face of an insulation sheet at a predetermined interval and adhere closely to the body surface of a muscle, an electrical stimulation position and a position of detecting the muscle sound are constant and it is possible to quantitatively detect the amplitude or frequency of an evoked mechanomyogram MMG, independent of the electrical stimulation position and the muscle sound detection position.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT
