Proposal of a computational interface of biofeedback for rehabilitation of victims of stroke

Biofeedback is a method of self-control of physiological responses through training. These biological responses can be the level of muscle tension, skin temperature, brain activity, heart rate or psychophysiological responses that are characterized by the level of anxiety, stress, relaxation or excitement of a person. Through this information, the individual will be able to modify or control any of these behaviors to reach a desired pattern, defined by a specialist of the area. This work presents a proposal of the creation of a computational system in real time for biofeedback with electromyography hardware system. The system will use miofeedback in sessions that will be performed with three types of virtual environments and the personal data of the patients and the data of the sessions obtained can be stored for posterior analysis. It was found that the biofeedback therapies were understood by the volunteers, giving the feedback of the muscle contraction and the sessions were dynamic, because of the use of the three-dimensional virtual environments and music on the therapies. These therapies can be used on the treatment of many pathologies and psychological states and will be used in patients which were victims of stroke.
