Stroke Rehabilitation: Virtual Reality works

In this interesting meta-analysis about the effects of virtual reality technology on the functional outcome of upper limb motor weakness after stroke, Saposnik G et al mentioned that Virtual reality (VR) technology is a novel adjunctive therapy that could be applied in neurorehabilitation. (Stroke. 2011; 42:1380-1386). Eleven of 12 studies showed a significant benefit toward VR for the selected outcomes. The results showed that among observational studies, there was a 14.7% improvement in motor impairment and a 20.1% improvement in motor function after VR. The authors concluded their meta-analysis by stating that VR and video game applications are novel and potentially useful technologies that can be combined with conventional rehabilitation for upper arm improvement after stroke.
