Loss of hand function as a result of upper limb paresis after a stroke
leads to reduced independence. Robotic-assisted therapy with virtual reality
leads to improvements in motor function, but there is a need to improve the
cost-benefit ratio of these therapies. This case series study investigated
augmented reality computer games which provided a rewarded, goal-directed task to
upper limb rehabilitation via a gravity supported reaching task. METHODS: A
computer game was developed to motivate chronic stroke survivors to undertake
gravity supported reaching tasks performed on a table, and a focus group study
investigated the application of this device for rehabilitation. From the focus
group, a simple device was developed to improve the quality of the exercise and a
further focus group study investigated a variety of computer games to determine
motivations for undertaking rehabilitation exercises. RESULTS: Of the four
participants in the case study, two showed improvement in ability to play the
game and in arm function. Participants enjoyed playing a range of computer games
and felt that the system provided a worthwhile exercise. Motivation for undertaking exercise with the system included: intellectual stimulation during
game play, feedback such as game score, gaining physical benefits from the
exercise, the system tolerating varying levels of disability, ability to relate
to the game and ability to use the system in social groups. CONCLUSIONS: A
low-cost device has been developed which increases the exercise of gravity
supported reaching movements, provides goal-directed tasks with rewards and
motivates the user to undertake extended rehabilitation.
