Paper Abstract:
|
This paper presents a proposal of upper-limb post-stroke rehabilitation using augmented reality combined with the mental
practice. We propose a treatment to improve motor function after a stroke, combining virtual therapy for the affected side
with mental practice. This treatment is intended for use with patients at least 6 months after the stroke with stable motor
deficits and without understanding deficits. Physiotherapists induce patients' mental practices so that they execute the
assigned tasks in the augmented reality environment. In the augmented reality environment, patients can visualize
themselves and their surroundings, just like in a mirror. However, a virtual upper-limb is superimposed over their real
paralyzed upper-limb and the real paralyzed upper-limb is removed from the final image, to avoid phantom upper-limb
visualization. A set of proposed exercises was developed and include low complexity movements as shoulder inflection,
shoulder abduction, shoulder adduction and fist extension, as well as high complexity movements like reach and grasp a
target, drag it to the desired position and release it. We believe that the proposed system can be used to examine the
efficacy of using visual stimuli and motor imagery training in the rehabilitation of hemiparesis. |
