An affordable, computerized, table-based exercise system for stroke survivors

Loss of hand function as a result of upper limb paresis after a stroke leads to a loss of independence and the strength of the paretic upper limb is strongly related to measures of activity. Robotic-assisted therapy with virtual reality, leads to improvements in motor function, but, there is a need to improve the cost-to-benefit ratio of these therapies. This case series study investigated an augmented reality computer game which provided a rewarded, goal-directed task to upper limb rehabilitation via a reaching task motivated by a computer game. A device was developed to increase the exercise effort for the table-based therapy. Of the 4 participants in the case study, 2 showed improvement in ability to play the game and in arm function. Participants felt that the system provided a worthwhile exercise that they would carry out in a home rehabilitation setting.
