MUSCLE ACTIVITY ESTIMATION APPARATUS, MUSCLE ACTIVITY ESTIMATION METHOD, AND MUSCLE ACTIVITY ESTIMATION PROCESSING PROGRAM

摘要

To estimate muscle activity on the basis of biopotential signal measurement at a measurement area to which measurement electrodes for a subject can be constantly stuck.SOLUTION: A muscle activity estimation apparatus according to one embodiment includes: biopotential signal measurement means that measures a first biopotential signal as a biopotential signal of an estimation object side of the muscle activity in a subject, and a second biopotential signal as a biopotential signal of a site that is different from the estimation object site and whose body shape variation by exercise is smaller than that of the estimation object site; signal preprocessing means that calculates root-mean-squares of the first and second biopotential signals respectively and outputs them; extraction mans that extracts a parameter associating preprocessing results of the first and second biopotential signals; and estimation means that estimates the muscle activity of the estimation object site on the basis of the root-mean-square of the second biopotential signal and the parameter.SELECTED DRAWING: Figure 1
