Virtual Reality Rehabilitation for Individuals With Lower Limb Amputation

A custom designed Virtual Gait Retraining System (VGRS) is being adapted for balance and mobility rehabilitation in individuals with transtibial amputation. The system is composed of a treadmill that can simulate different environmental situations such as walking up stairs and hills and going around curves. The treadmill is synchronized with an immersive display and an avatar of the user. The combination of variable terrain and visual feedback is extremely promising as a means for amputee patients to achieve improved functional mobility after gait training. The proposed work is relevant to public health because it is the first step in developing a novel rehabilitation system that will use visual feedback for gait training in amputees and others with pathological gait disorders. The research is pertinent to the mission of the Department of Veterans Affairs which is committed to improve the quality of life of Veterans with disability.
