Abstract

An Assistive Passive Pelvic Device for Gait Training and Rehabilitation Using Locomotion Dynamic Model

Highlights

  • There are a large number of people who are suffer from disability in walking because of occurring some injuries such as spinal cord injury and stroke

  • In former research works, the desired trajectory of motion of lower legs had been estimated for subject, in present simulation work, we provide real desired trajectories using gait pattern of subject obtained in a gait analysis laboratory

  • We study the effect of device on optimum pelvic rotations by varying the determined values of some geometrical and inertia parameters of subject employing the orthosis during gait on treadmill

Summary

Introduction

There are a large number of people who are suffer from disability in walking because of occurring some injuries such as spinal cord injury and stroke. Pietrusinski et al [6] designed a Robotic Gait Rehabilitation (RGR) trainer, which apply corrective force fields to the pelvis depending on patient’s efforts based on deviations from normal pelvic motion. We present an innovative application of optimized passive elements (such as masses and springs) in design of a pelvic assistive device to assist and/or improve the human gait. This device would be connected to the pelvis and move it in an appropriate trajectory during the gait cycle. 4170 An Assistive Passive Pelvic Device for Gait Training and Rehabilitation Using Locomotion Dynamic Model
