Title:
JOINT EVALUATING DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/085662
Kind Code:
A1
Abstract:
A joint evaluating device (10) is provided with: an inertial sensor unit (30) which is mounted in the vicinity of a joint linking bones on both sides thereof, with the joint axis of the joint and a detection axis parallel to one another, and which detects, as a waveform signal, the movement of the bones of the joint axis of which the range of motion of joint movement is limited, among the joint axes; a load detecting unit (34) which detects a load applied to the joint; a data acquiring unit (21) which, when generation of a load is detected, acquires the waveform signal detected by the inertial sensor unit (30), in the time direction and the intensity direction; and a feature quantity calculating unit (22) which analyzes the waveform signal to calculate a feature quantity for evaluating the quality of movement of the joint. As a result, the behavior of the joint in the direction in which the range of motion is limited is detected in an anatomically meaningful way, and an injury, disability or the like is easily and accurately evaluated and predicted.
