Electrical stimulation device, training apparatus, and electrical stimulation method

摘要

Provided is an electrical stimulation device including a first to fourth electrodes, and an electrical stimulation generation section which supplies an electrical stimulation signal to each of the first to fourth electrodes. The electrical stimulation generation section supplies, to the first and second electrodes, an electrical stimulation signal according to a first stimulation pattern, and supplies, to the third and fourth electrodes, an electrical stimulation signal according to a second stimulation pattern. The first stimulation pattern is set so that an electrical stimulation signal for changing stimulation intensity according to a first waveform is supplied to the first electrode, and an electrical stimulation signal for changing stimulation intensity according to a second waveform is supplied to the second electrode, the second waveform being increased and decreased in conjunction with the first waveform. The second stimulation pattern is set so that an electrical stimulation signal for changing stimulation intensity according to a third waveform is supplied to the third electrode, and an electrical stimulation signal for changing stimulation intensity according to a fourth waveform is supplied to the fourth electrode, the fourth waveform being increased and decreased in conjunction with the third waveform. The electrical stimulation generation section alternately performs electrical stimulation of the first stimulation pattern and electrical stimulation of the second stimulation pattern.
