Virtual reality training for stroke rehabilitation

Objective: To evaluate the effectiveness of a 2-D virtual reality (2DVR) programme in the training of people with stroke on how to access and use the station facilities of the Mass Transit Railway (MTR). Method: A flat-screen 2DVR based training programme and a corresponding, typical psycho-educational programme with video modelling were developed for comparison through a research design that involved a randomised control group pre-test and post-test. Results: Twenty and sixteen subjects respectively received 10 training sessions using the 2DVR strategy and a video-based psycho-educational programme. An additional 22 subjects formed the control group. They were assessed by using a behavioural checklist of MTR skills and a newly validated MTR self-efficacy scale. The subjects of both training groups showed a significant improvement in their knowledge, skills and self-efficacy in using the MTR (p < 0.01), whereas, the MTR skills and self-efficacy of the control group remained stable over a four-week interval. Conclusion: Though both training programmes were effective in training the patients with stroke, they demonstrated differential improvements in MTR skills and related self-efficacy. Additional studies are recommended to identify the most effective training procedures for maintaining these skills and the best transfer ratio in the training of VR-based community living skills of people with stroke.
