Abstract

A high number of stroke survivors experience limitations in balance and gait abilities. Thus, an improvement in gait ability is an important goal in the rehabilitation of hemiplegic stroke survivors. This study aimed to investigate the effect of using the one-arm motorized walker, a hemi-walker developed to assist hemiplegic stroke survivors in gait training and activities of daily living, on the improvement in gait ability in hemiplegic stroke survivors. Eleven hemiplegic stroke survivors who met the inclusion criteria were included. The participants were instructed to walk thrice using traditional walking aids on a gait mat and then to walk thrice using the one-arm motorized walker. During each walk, spatiotemporal gait parameters, including velocity, cadence, step length, stride length, single support time, and double support time, were evaluated using a gait analysis system. Velocity and cadence significantly increased when the participants walked using the one-arm motorized walker compared to those who used traditional walking aids (p< 0.05), whereas double support time significantly decreased for both the more affected and less affected sides (p< 0.05). However, no significant difference was observed in terms of step length and single support time. The one-arm motorized walker may have a positive effect on the improvement of gait ability in hemiplegic stroke survivors. It can be an effective walking aid for hemiplegic stroke survivors who experience difficulties in independent walking.
