On-Line Electromyographic Signal Processing System

An on-line electromyographic signal (EMG) processing system using a microcomputer is described. It allows real-time diagnostic aid, interference electromyogram acquisition and processing, and signal-base constitution. It includes a preprocessing unit, microprocessor based, with specialized routines (segmentation of motor unit action potentials (MUAP) in multiunit records, programmable sample frequency and duration recording, as well as specific multichannel operation), graphic display microcomputer with hard copy, mass storage, and force experimental setup (strain gauge connected to digital voltmeter).
