Commercial interactive game consoles including the Nintendo Wii™ and the Sony Playstation Eyetoy™ have been used in stroke rehabilitation with variable success and seemed to be safe, feasible and effective treatment options. The more recently released Xbox Kinect™ game console has superiorities to the others such as not requiring any special controller and having a more sensitive sensor which provides more accurate motion-capturing. However, there is limited evidence on clinical utility of the Xbox Kinect™ in stroke rehabilitation. Currently it has been designed for physically and mentally healthy people just like previous consoles. Therefore, the safety and feasibility of the system should be evaluated in first place before using it as an alternative or adjunctive training method in stroke patients. To the best of our knowledge, no studies have evaluated the clinical feasibility of the Xbox Kinect™ in stroke rehabilitation. The aim of this pilot study was to evaluate the feasibility and safety of the Xbox Kinect™ training of upper extremity in subacute stroke rehabilitation. The secondary aim was to evaluate its efficacy on upper extremity motor and functional recovery.
