An elecroestimulation system synchronized with movement for active rehabilitation

Motor rehabilitation is one of the aspects which have great impact in the treatment of injuries, as they prevent that temporary disability due to an accident or illness, become permanently disabled. There are different types of motor rehabilitation carried out depending on the type of lesion and the patient characteristics; they can be grouped into passive rehabilitation, when exercises are performed with the help of the therapist, and active rehabilitation, when the patient must performs the exercises all alone. In passive rehabilitation, different tools are used to help patients, one of them is electrostimulation. Electrostimulation however is currently used before or after the exercises prescribed by the therapist. This paper describes a system that generates percutaneous electrical stimulation signals, which can be used, while the patient gets a session of active rehabilitation, increasing the efficiency of the exercises performed by him. Partial results of this research will allow handling a specific type of electrostimulation for different bending angles for the lower limb.
