Using virtual reality to advance the understanding and rehabilitation of gait impairments in Parkinson's disease

Abstract

Virtual reality (VR) provides a unique platform to study the complex interactions between an individual's movement and their environment. Although this innovative technology has not yet been widely used in Parkinson's disease (PD) research, it has tremendous potential to advance both our understanding and treatment of gait impairments. In this chapter, we will first outline the variety of virtual reality systems available and contrast the associated advantages and disadvantages that warrant consideration for using virtual reality in experimental and/or therapeutic settings. We will then discuss the utility of VR in the scientific exploration of mechanisms that underlie gait impairments in PD. Finally, we will examine the effectiveness of using VR in a therapeutic setting based on the current research, and provide future directions for therapeutic interventions for gait in PD utilizing virtual reality.
