Abstract
An action state estimation apparatus is provided that includes a sampling portion, a statistic calculation portion, an action state model storage, and an estimation calculation portion. The sampling portion samples a displacement measurement signal within a predetermined time and generates displacement measurement data. The statistic calculation portion calculates a statistic of the displacement measurement data. The action state model storage stores an action state model modeled by associating the statistic with a loaded state of a muscle of the test subject. The estimation calculation portion estimates the loaded state by setting the statistic as an input vector and using the action state model.
