Claim Text:
1. A muscle support method, comprising: detecting, in a detection mode, a first muscle potential of a first muscle, with a first muscle potential sensor in a sheet member attachable to skin covering the first muscle; calculating, in the detection mode, a first low-frequency component ratio comprising a ratio of an integral value of a low-frequency component of the first muscle potential to an integral value of an entire bandwidth component of the first muscle potential; determining, in the detection mode, whether the first muscle is to be supported, based on the first low-frequency component ratio; detecting, in a support mode, immediately after the detection mode, a second muscle potential of the first muscle; causing a first current, in the support mode, at a start time, between a first electrical muscle stimulation electrode pair in the sheet member and through the first muscle, if the first muscle is to be supported, the start time being determined based on the second muscle potential; and stopping the first current in the support mode, at a second time, the second time being determined based on an average potential of the first muscle detected by the first muscle potential sensor.
