Nowadays stroke is the leading cause of disability. Ischemia or haemorrhage in the brain may be counted among the main reasons of cerebro vascular accident which ultimately results in stroke. In the case of stroke victims, it is widely accepted that natural recovery accounts for the motor as well as functional restoration taking place in the first months following the stroke incident. Latest evidence has shown that further development can be achieved if neural organisation is made to order. Incompletely damaged neural pathways can be reinstituted with neurons not normally occupied in an activity can be engaged. There has been a lot of work on power-assisted device therapy and as a result, there is increasingly wide and diverse range of systems. There are variety of actuation methods and control strategies and they are targeted at different disabilities. This review explores the art in rehabilitation exoskeletons for the upper arm and hand. Our view regarding future directions in the area of Rehabilitation Exoskeleton hand.
