- Physiological responses during performance within a virtual scenario for the rehabilitation of motor deficitsPublication . Cameirão, Mónica S.; Bermúdez i Badia, Sergi; Mayank, Kumar; Guger, Christoph; Verschure, Paul F.M.J.Real-time physiological feedback can be used to modulate a virtual reality (VR) experience. It is not obvious, however, which parameters are most effective in achieving this such as heart rate variability and or the electrodermal response. Here we address this question by assessing the impact of the events generated by a VR based rehabilitation system on the affective state of human users. We show how the Rehabilitation Gaming System (RGS), a tool developed for the rehabilitation of motor deficits following stroke, can be enhanced using the online monitoring of bodily changes that are not under direct voluntary control. We show specific effects of the RGS on the autonomic nervous system and we propose how to use these for the modulation of the emotional state of the subject and performance.
- Using a multi-task adaptive vr system for upper limb rehabilitation in the acute phase of strokePublication . Cameirão, Mónica S.; Bermúdez i Badia, Sergi; Oller, Esther Duarte; Verschure, Paul F.M.J.Nowadays, stroke has become one the main causes of adult disability leading to life-lasting effects, including motor and cognitive deficits. Here we explore the benefits of the use of virtual reality (VR) for the rehabilitation of motor deficits following stroke. We have developed the Rehabilitation Gaming System (RGS), a VR-based apparatus designed for the treatment of the upper extremities. The RGS is a multi-level adaptive system that provides a task oriented training of graded complexity that is online adjusted to the capabilities of the patients. We show results from an ongoing study that evaluates the impact of this system on the recovery of patients in the acute phase of stroke (n=14). The results suggest that the system induces a sustained improvement during treatment, with observed benefits in the performance of activities of daily living.
