Impacts of Application of Virtual Reality on Gait and Balance for Stroke Patients

Kaohsiung Medical University Chung-Ho Memorial Hospital17 enrolled

Overview

The goal of this clinical trial is to learn about effects of virtual reality combined with conventional therapy on the balance, gait, and quality of life in stroke patients in the subacute and chronic stages. The main questions it aims to answer are: • Virtual reality combined conventional therapy interventions can improve the gait, balance and functional status of stroke patients or not? Participants will asked to do about 3 tasks in virtual reality intervention * Walk in the flat ground * Cross the obstacle on the ground * Cross to moving obstacles

The investigators referred to the scenes designed by previous studies to develop the three virtual environments employed in this study and made slight modifications according to Taiwan's conditions. Google Earth Virtual Reality (Google Inc., Mountain View, California, U.S., 2017) was uesd for the first and second task and Street Champ Virtual Reality (Zynk Software Srl , Cluj, Romania, 2016) was used for the third task. Time constraints, terrain changes, and moving obstacles were set to increase the difficulty of the walking task. The speed obtained by the 10-m walking pretest was used as the training benchmark. The participants had to complete a task three times to proceed to the next level. For Patient Registries: on-site audit.The subjects were referred from the rehabilitation Clinic of Kaohsiung Municipal Ta-Tung Hospital

Outcomes

Primary Outcomes

Walking pace

Use the 10 meters walking test to show the outcomes that presents in m/s.

Time frame: Measure changes from baseline walking pace tested before the intervention to one week after completion of all interventions.

Walking endurance

Use the 6 minutes walking test to show the outcomes that calculate the distance in meters.

Time frame: Measure changes from baseline walking distance tested before the intervention to one week after completion of all interventions.

Balance test

Use the Berg Balance Scale to show the balance outcomes. It consists of 14 items scored 0 to 4 for a total of 56 points. A higher score means lower fall risk.

Time frame: Measure changes from baseline Berg Balance Scale score tested before the intervention to one week after completion of all interventions.

Activities-specific balance confidence scale

Use the Chinese version of the activities-specific balance confidence scale to show the outcomes.It consists of 15 items every item score on 0 to 100. 0 means no confidence to perform the tasks, 100 means fully confidence to finish tasks.

Time frame: Measure changes from baseline score of Chinese version of the activities-specific balance confidence scale tested before the intervention to one week after completion of all interventions.
