An evaluation method, device, and system for a human motor capacity. The method comprises: acquiring, by means of multiple inertial sensors (74), motion posture data of a human body part under test, wherein the part under test comprises at least one joint, and the multiple inertial sensors (74) are fastened, according to a predetermined human motion model, to body members in connection with the joint (110); calculating, according to the motion posture data, a rotation angle of the at least one joint (120); and determining, according to the rotation angle of the at least one joint, a motor capacity of the part under test (130).
