PURPOSE:To enable the easy and precise mounting of a sensor body to a subject part by connecting an electrode to a snap terminal on the bottom of the sensor body for a muscle measurement device in such a way as to be freely detachable via a snap. CONSTITUTION:There are provided an electrode 9 and an electronic circuit part, and active potential is detected with the electrode 9 fitted to the muscle inspection chart of a subject. The active potential so detected is subjected to a waveform process in the electronic circuit part and a muscle chart is obtained with a muscle measurement device on the basis of the active potential so processed. Snap terminal parts 3 and 4 are provided on the bottom of a sensor body 1 for the muscle measurement device, and the electrode 9 is so connected to the terminal parts 3 and 4 as to be freely detachable via snaps. According to the aforesaid construction, the sensor body 1 can be mounted to the subject simply and precisely and the shift of the electrode 5 rarely occurs during measurement. Also, there is no oscillation of a lead wire between a preamp 2 and the electrode 9, and it is possible to substantially reduce a noise called 'arch fact'. |
