SHOULDER STIFFNESS DETECTION DEVICE AND SHOULDER STIFFNESS DETECTION METHOD

摘要

A shoulder stiffness detection device (10) comprises a plurality of biosignal detection electrodes (211, 212), a detection signal generation unit (30), and a calculation unit (40). The plurality of biosignal detection electrodes (211, 212) are worn at positions separated from each other on skin covering muscles that cause shoulder stiffness in the wearer. The detection signal generation unit (30) uses biosignals each measured by the plurality of biosignal detection electrodes (211, 212) and generates detection signals. The calculation unit (40) uses the detection signals to detect the amount of muscle fatigue and detects shoulder stiffness from the amount of fatigue.
