Diseño y construcción de un monitor electromiográfico basado en la tecnología de los micro-controladores

Abstract

This paper presents the design, construction and installation of a system for the acquisition of electromyographic signals from the muscles of the human body. Electromyography is the electrophysiological study of the neuromuscular system, which registers, by means of electrodes, electrical potentials that occur in skeletal muscles when activated. It is used to check the condition of the nerves that control muscle and it allows to accurately detect the degree of compression or nerve pain; also helps in measuring the speed of movement of an electrical stimulus. For the realization of the electromyogram on the skin surface electrodes are placed, and connected to the amplifier that measures the difference of electrical potential between the electrodes; then this potential is filtered and finally the wave is visualized in the computer.
