Abstract
Background and Objectives: Rett Syndrome (RTT) is a development disorder with a known genetic origin that causes a child to lose purposeful use of their hands and develop characteristic stereotypical repetitive hand movements. Through the use of Virtual Reality (VR), the frequency, length, and intensity of therapy sessions can be enhanced, leading to improved upper extremity function.
Methods: The objective was to develop a VR system, namely VR_Color Tracker, specifically tailored for persons with RTT and designed to decrease the characteristic stereotypical repetitive hand movements and increase the use of hands in skilled function. The VR_Color Tracker was created, tested, revised, and retested through the use of a multi-level, iterative development process. Limitations such as technological restrictions and effective tracking were addressed prior to testing with a RTT participant.
Results: A feasibility investigation was carried out, a System Usability Scale (SUS) was completed with the researchers, and the system’s usability was determined to be in the seventieth percentile.
Conclusions: The VR_Color Tracker is feasible to use for an individualized approach to RTT therapy, but more research is needed to determine its clinical efficacy
