Applied Evaluation Research Of Children’s Exoskeleton For Rehabilitation Training

At present,exoskeleton robots have been applied on a certain scale in the field of adult rehabilitation,but they have not formed a large-scale application scale in children’s rehabilitation fields such as cerebral palsy,and there is a lack of mature children’s exoskeleton robots in the market,and the research on exoskeleton robots on children’s motor ability is also very preliminary,lack of exoskeleton robots on children’s gait and motor function evaluation.Therefore,this paper studies the movement function and gait influence of AIDER child exoskeleton robot in walking state,in order to verify whether the child exoskeleton robot is feasible for children’s ground gait training,and whether the gait biomechanical change accords with the characteristics of normal healthy gait change.The main contents include the following aspects:Based on the mechanism of joint movement and gait biomechanics,the evaluation indexes were selected from the whole exoskeleton man-machine system and the joint motion characteristics of wearable children,then construct an evaluation parameter system.From the point of view of the exoskeleton man-machine system as a whole,this paper explores the movement stability of the exoskeleton system,the passivity of the human-machine system,the characteristics of kinematic and dynamic parameters,and the gait symmetry when children wear the exoskeleton for walking training.From the perspective of the wearer,explore the motion stability,symmetry and difference of the lower limb joints of children walking with exoskeleton robot.A more complete evaluation framework is built for the actual verification of the movement function of the evaluation index system in the walking state of the child exoskeleton robot.Based on the established evaluation index system of child exoskeleton robot,the motion function of AIDER child exoskeleton robot in walking state is verified systematically.According to the selected index parameters and evaluation purposes,design an experimental plan.Use the Vicon three-dimensional gait analysis system and force plate to collect the gait data,kinematics and dynamics of the experimental children under the two conditions of not wearing and wearing AIDER children’s exoskeleton robot,then process,calculate,statistics and analyze the data collected by the experiment.According to the gait analysis theory and the functional characteristics of the exoskeleton robot system,this paper selects different evaluation index systems from two aspects and establishes a complete evaluation system for the walking function of the children’s exoskeleton robot system,and conducts experimental verification based on the actual system.Through the calculation and analysis of various evaluation indicators,the application evaluation of the walking function of AIDER children’s exoskeleton robot is realized,and it is verified that the children’s exoskeleton robot is feasible for children’s ground gait training,which can provide reference data for the follow-up improvement of AIDER children’s exoskeleton robot in walking function and clinical gait correction experiment in children with cerebral palsy.
