Method for determining the margin of the lower limb muscle strength, and lower limb muscle strength evaluation apparatus used in this

摘要

PROBLEM TO BE SOLVED: To provide a leg strength evaluation method in which the convenience is excellent and the leg strength can be evaluated accurately, and to provide a leg strength evaluation device using the same.SOLUTION: The leg strength evaluation method includes: a step in which an acceleration and an angular velocity that show the movements of an upper-body section and femoral region in a subject H during a posture change from a maximum squat down posture which is a posture in which the subject H squats down as much as possible to a standing posture are acquired by an upper-body section sensor and a femoral region sensor; and a step in which the maximum value max(T(t)) of the sum of the joint moment of a hip joint and a knee joint of the subject H is acquired from the acceleration and the angular velocity of the upper-body section and the femoral region, and the margin degree of the leg strength is calculated based on the maximum value and the reference value Tthat shows a minimum muscular strength necessary for the subject H to stand up from the squatting down posture.
