Development of LIDAR Based Gait Training System with Gait Assessment

Abstract

Due to the limitations of the clinical gait training and gait assessment devices, the gait training systems with capabilities of gait parameter measurement have been developed so that patients can use these devices in ambulatory condition for daily rehabilitation. This research proposes a wheeled walker equipped with a 2D laser scanner (LIDAR) for a novel prototype of gait training system. Gait parameters such as stride length and step length were concurrently measured based on this developed system and a clinical gait assessment system (Qualisys) in order to investigate the performance of this prototype. It was found that the assessments of these gait parameters were appropriately preformed with the sufficient accuracy. This developed system may effectively enable daily gait training for community use.
