Abstract :
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
