Dynamic Analysis of Movement for Walking-aid Users

Abstract

This study aims to establish a power-driven walking-aid system with measuring function The system consists of a powered base and a stick By wearing force sensors external forces on the user during the transition from sitting to standing and walking can be recorded in real-time Besides the user’s movement is recorded with a camera and then analyzed with software As for body state recording Kinect system is used to record the user’s movement and identify the corresponding joint positions; force sensitive resistors are placed on the user’s feet to measure the normal force based on the equivalent-area simplification; load cells are installed on the handle of stick to measure the force that the user exerts on the walking-aid system In particular instead of using wired system all measured data are transmitted with two Bluetooth devices to avoid hindering the user’s movement At last based on the measured data OpenSIM is utilized to build up a human musculoskeletal model and then calculate the joint torques and muscle forces respectively The final result shows that the estimated muscle forces and joint torques are at a certain degree of reliability
