Efficacy of closed loop feedback system with augmented virtual reality visual cues training on gait and functional performance in stroke patients

Abstract

The traditional gait training techniques, which are not based on principles of motor control lack requisites in terms of training intensity, duration and enough practice to have any meaningful carryover effect. Therefore, the aim of this study is to investigate the efficacy closed loop visual cues incorporated augmented reality environment on functional gait and community ambulation in stroke patients. A randomized control trial with control group was designed and 14 subjected were recruited in each group. Four weeks of augmented reality based closed loop visual cue training was given to experimental group. Compared to control group, the Walking speed, cadence, stride length of paretic and non-paretic limb, symmetrical walking and SIS-SF score improved 25.1%, -5.5%, 29.3%, 8.3%, 5.3% and 29.1% respectively. The finding of our study supports the beneficial effect of augmented reality based closed loop visual cue training for improving the gait and functional ambulation in stroke patients.
