PROBLEM TO BE SOLVED: To provide an electro-stimulator which causes less muscle fatigue, and which can efficiently prevent reduction of muscle force.SOLUTION: An electro-stimulator comprises: a control part 3 for applying, as a signal to be applied to a living body S from an electrode part 2, a low output signal which causes muscle fatigue hardly, but has less effect to muscle output, and a high output signal which relatively easily causes muscle fatigue but has large effect to the muscle output, in a time-variant state, to the electrode part 2.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】筋疲労が少なく、効果的に筋力低下を防止することができる電気刺激装置を提供する。【解決手段】電気刺激装置は、電極部2から生体Sに印加される信号として、筋疲労は起こしにくいが筋出力に対し効果が少ない低出力信号と、筋疲労は比較的起こしやすいが筋出力に対し効果が大きい高出力信号とに時間的に分けて電極部2に印加することができる制御部3を有する。【選択図】図1
