Sistema electrónico de rehabilitación para personas que padecen la enfermedad neuropática de parálisis facial periférica

Abstract

The development of this research aims to make a peripheral facial paralysis electronic rehabilitation system to help people who suffer from of it neuropathic disease, causing the affected person to be unable to control their own facial muscle movements, since the facial nerve injures the cranial nerves producing facial paralysis. The system starts from muscle contraction by electrostimulation, improving circulation through low frequencies and reactions of dead tissues by applying these electrical impulses, which are applied prior to detecting the state of the muscles in an area of the face with the electromyogram The signal generated by the electrostimulator is given in the form of a monophasic square wave with modulated amplitude to generate the electrical pulses, in addition both the pulse range and the frequency are between 1 to 100 Hz and the coupling phase with which the current is exerted. output is less than 10 mA in order to conserve the amperage that the human body supports. This method of electrical stimulation meets the needs of operation both in time and frequency in the rehabilitation process. The system allows entering time, frequency and pulse data which can be controlled mathematically, omitting all kinds of noise or alteration in the output signals. What contributes to the improvement of the health of patients with facial injuries by presenting itself within the reach of every health center since it is economical, which makes it replaceable with any type of existing machines on the market. To verify the operation and reliability of the system, it was applied to patients at the Bendiciones Rehabilitation Center, where favorable results were obtained.
