A data acquisition and signal processing system for EMG and acceleration signals

A data acquisition and signal processing system was designed to study the EMG (electromyogram) coordination and timing interplay of agonist and antagonist muscles during specific limb movements. The PC-based system collects EMG signals from two channels, corresponding to extensor and flexor muscles of the subject's upper arm. Six other channels are utilized for motion information obtained from two three-axis piezoelectric acceleration transducers attached to the subject's wrist. Based on the collected information, the stimulator (output) side of the system derives suitable stimulation patterns for the subject.<<ETX>>
