The sensor sheet, swallowing activity measuring device and swallowing activity measuring method

摘要

PROBLEM TO BE SOLVED: To provide a sensor sheet configured such that a plurality of electromyogram electrodes and a plurality of vibration pickups can be attached on the surface of an anterior neck region by a single work even if a measurer is not an expert, and to provide a swallowing activity measuring device for calculating muscle activity in the laryngeal based on an electromyogram and vibration measurement results.SOLUTION: A sensor sheet 110 is formed by previously fixing an electromyogram electrode and a vibration pickup to an adhesive sheet so as to match a muscular position to be measured, and is stuck on a subject to record waveform data measured. The recorded results of measurement are subjected to filtering or the like, and then a muscle activity analyzer 130 calculates a start time, a completion time, time duration, an initiation order and a completion order of the muscle activity related to swallowing. The muscle activity analyzer 130 uses the results of measurement of the plurality of vibration pickups for calculating the time when the food and drink pass a larynx, and calculates that the muscle activity is stopped only when the waveform of the electromyogram is successively lowered less than a threshold value beyond a certain period of time.
