Abstract

Stroke rehabilitation techniques have gathered an immense attention due to the addition of virtual reality environment for rehabilitation purposes. Current techniques involve ideas such as imitating various stroke rehabilitation exercises in virtual world. This makes rehabilitation process more attractive as compared to conventional methods and motivates the patient to continue the therapy. However, most of the virtual reality based stroke rehabilitation studies focus on patient performing sedentary rehabilitation exercises. In this chapter, we introduce our virtual reality based post stroke rehabilitation system that allows a post stroke patient to perform dynamic exercises. With the introduction of our system, we hope to increase post stroke patient's ability to perform their daily routine exercises independently. Our discussion in this chapter is mainly centered around collaboration of rehabilitation system with virtual reality software. We also detail the design process of our modern user interface for collecting useful data during rehabilitation. A simple experiment is carried out to validate the visibility of our system.

It has been estimated that, around 795,000 people in US suffer stroke each year. Stroke is considered as the 4th largest cause of preventable deaths and also cause of long term disability (Go et al., 2014), (“Stroke Facts | cdc.gov,” n.d.). It should also be noted that each year almost one-fourth, of the total stroke patients, have reported recurrent attack. Studies have shown that, chances of recurrent stroke attacks can be reduced, by performing regular physical activities or exercises recommended by the therapist (“Preventing Another Stroke | Stroke.org,” n.d.),(“Practice Guidelines: AHA/ASA Guidelines on Prevention of Recurrent Stroke - American Family Physician,” n.d.). However, person who had experienced a stroke may incur substantial disability, which in-turn makes them impossible to perform various physical activities. Therefore, various stroke related research activities are focused on system that could assist stroke patient’s to perform their physical activities with ease. Current research studies have introduced various VR related rehabilitation system for patients suffering from stroke (Burdea, 2003; Cameirao et al., 2007; Kizony et al., 2005; Kuttuva et al., 2006; Ma et al., 2007). Although, many techniques available for stroke rehabilitation include VR environment as an attractive feature, very few techniques concentrate on developing a home oriented system.
