Personal electromyographic biofeedback system “MyMyo”

Abstract

Typical EMG measurement system consists of one central device with several channels; which are connected to the central unit with wires. Central device samples data from channels and supplies energy for the channels. It transfers data further to a device providing the user with graphical interface. Connection from central device to user interface device can be with or without wires. Very common drawback of such systems is that the wires limit patient movements; make EMG measurements relatively uncomfortable and they are not available for personal use because of relatively high prices. The goal of this project was to design, construct and test a compact-size, wireless and surface-electrode EMG measurement system. The intention is that device could be used as a single channel wireless EMG acquisition system which uses smartphone as a graphical user interface. Due to its simplicity and low price it is hoped to be available for home, everyday, personal use.
