Virtual reality based rehabilitation seems to be as effective on walking speed, balance and mobility compared to standard rehabilitation regimen in people with stroke. 

It is widely accepted that a high dosage of task-oriented exercises is favourable in rehabilitation after stroke. Virtual reality simulates real-world activities in which the user has the sense of being present in and in control over this simulated environment. Because virtual reality based rehabilitation incorporates more task-oriented exercises compared to standard rehabilitation it is assumed to be more beneficial.
