Passageway modeling between neural signal and muscle activation

This paper deals with an acquisition and recognition of Electromyography (EMG) signals, their processing to get the neural activation, their transformation to muscle activation and the relationship of neural activation to muscle activation. This issue is related to the stability of an EMG-based orthotic control. The EMG signals are recorded with surface electrodes attached to the skin on top of the selected muscles and they reflect the activation of the muscles. The acquired EMG patterns are processed in a manner to remove the non-target patterns. The parameters for processing of EMG signals are suggested to make the signal suitable for calculating muscle activation and muscle force.
