WALKING MOTION ASSISTANCE DEVICE

Title:

WALKING MOTION ASSISTANCE DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/153025

Kind Code:

A1

Abstract:

A walking motion assistance device of the present invention comprises: a casing mountable to left and right knee ankle foot orthoses; an electric motor; a drive arm having a proximal end and a distal end, the proximal end being rotationally driven around a drive side pivot axis line and the distal end being operatively coupled to a lower thigh frame of the knee ankle foot orthosis, by power of the electric motor; a rotation sensor that detects the drive arm's swing position around the drive side pivot axis line; a walking motion state detection sensor; and a control device. The control device recognizes, as a reference value, a detection signal input from the rotation sensor when the lower thigh is maximally stretched, determines the left and right of the mounted legs on the basis of a detection signal other than the reference value, and selects the left and right of assistance force control data used when the assistance force to be output from the electric motor is calculated.
