Abstract

There is a need to consider a new framework for the development of virtual rehabilitation systems that are suitable for routine clinical use. With this in mind, a three-dimensional virtual reality (VR) system -the Surrey Virtual Reality System (SVRS) - that has been developed at the Centre for Biomedical Engineering , with the aim to be used as part of a rehabilitation programme for children with cerebral palsy (CP). Prior to the use of the SVRS with children with CP, opinions on the SVRS were gathered from 13 young adults aged between 19 and 25. The young adults were invited to review static 3D images and then to interact with two VR scenarios. They were then asked to walk on a treadmill at a number of self-selected and self-controlled walking speeds. During the tests, each participant answered a questionnaire that provided feedback on the SVRS and its practicality. The analysis of their opinions shows that the young adults were satisfied with the quality of the SVRS presentation. The results also show the feasibility of an algorithm for a self-controlled treadmill speed based on kinematic marker data with minimal encumbrance to the subject. All the users who used the SVRS were satisfied with the performance and the safety of the SVRS. In conclusion, the SVRS appears to provide a safe and visually acceptable virtual training environment.
