- Abstract
Stroke is a neurological problem that may cause severe sensorimotor impairments. Motor recovery is an important goal for neurorehabilitation. Virtual Reality (VR) provides positive and dynamic individual-task interaction. Nevertheless, the use of VR as an intervention technique in rehabilitation raises the question about the similarity of sensory-motor perception between real and virtual environments. This similarity between real and virtual environments could be explored in neurorehabilitation. This research compared brain activity and arm movement during virtual and real dart throwing tasks between stroke patients and healthy subjects. The participants included two stroke patients and two healthy individuals. During evaluation participants performed 15 trials during a real dart throwing task, and 15 trials during a virtual dart throwing task. Stroke patients performed the tasks with the paretic upper limb. The brain activity was captured with an Emotiv EPOC® system (portable EEG system with 14 sensors + 2 references). The brain activity data was supported on power spectral analysis of Beta waves at 22 Hz, and Gamma waves at 40Hz. Data revealed similarities on brain activity between virtual and real dart game tasks, with activation of the primary motor cortex in the right cerebral hemisphere (FC6), for both stroke and healthy participants.
