A Mixed Reality-Based Exercise Program for Upper-Limb Post-Stroke Rehabilitation

Gilda Aparecida de AssisAna Grasielle Dionísio CorreaCicero José Nunes VazRoseli De Deus Lopes

This paper describes a proposal of exercises for poststroke rehabilitation of the upper-limb movements using mixed reality combined with mental practice. Physiotherapists induce patients' mental practices so that they execute the assigned tasks in the mixed reality environment. In the mixed 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. The set of proposed exercises include low complexity movements as shoulder infection, shoulder abduction, shoulder adduction, fist extension, and hand grasping as well as high complexity movements like reach and grasp a ball, drag it to the desired position and release it. We be lieve that the proposed system can be used to verify the effectiveness of visual stimuli for post-stroke rehabili tation. The system will allow post-stroke patients and their caregivers to perform the rehabilitation exercises at home. Also, this system will provide physiotherapy students the possibility to repeat medical training.
