Proposal of a simple estimation method of lower limb muscle strength based on function-specific effective muscle theory.

Abstract

In this study, in order to provide standing support that considers muscle strength that varies depending on the individual, the support movement must be changed according to the individual's muscle strength status. Therefore, it is necessary to measure individual muscle strength, and many previous studies used electromyographs to measure lower limb muscle strength. However, because the person using the electromyograph must have expertise in measuring muscle strength, ordinary caregivers cannot easily use it in their nursing homes. Furthermore, measurement is difficult because many electrodes must be attached to the subject's body when using the electromyograph. Therefore, this paper proposes a simple method for estimating lower limb muscle strength based on function-specific effective muscle theory. Using the proposed method, a person without expertise can estimate the muscle strength of 3 versus 6 muscles of the lower limb.
