A theoretical model of the electromyographic (EMG) signal has been developed. In the model, the neural pulse train inputs were considered to be point processes which passed through linear, time-invariant systems that represented the respective motor unit action potential. The outputs were then summed to produce the EMG. It was assumed, that in the production of muscle force, the controlled parameter was the number of active motor units, n(t). The model then showed that the EMG can be…

The paper reviews the fundamental components of stochastic and motorunit-based models of the surface electromyogram (SEMG) and the relationship between SEMG and force during natural dynamic movements is much too complex to model in terms of single motor units.

Power Spectrum Analysis

A muscle-structured stimulation model based on anatomical and physiological data is produced and the stimulation results suggested that the behaviour of the third parameter is related to the number of active motor units at the shallow layer of a muscle.

Modeling and Simulation of EMG Signal and H-Reflex in Healthy Human Subject

The purpose was to model the recorded EMG from the FCR muscle in response to both the electrical stimulation and the brain commands during motor imagery, and to capture the qualitative behavior of the H-reflex and how physiological variables change its waveform.

Investigation on parametric analysis of dynamic EMG signals by a muscle-structured simulation model

The authors estimated k parameters up to the fifth order for the surface EMG signals of a masseter muscle during rapid open-close movement of the lower jaw, a ballistic contraction, and fatigue and suggested that the behavior of the third parameter is related to the number of active motor units at the shallow layer of a muscle.

A mathematical model of myoelectric signals obtained during locomotion

An analytical expression for the myoelectric signal was derived using the integral pulse frequency and amplitude modulation (IPFAM) approach. The results indicate that, in the frequency domain, the

Sequential Multistate EMG Signal Processor

Two sequential processors are developed for the EMG signal and it is shown that compared to an optimal Bayes receiver the sequential processor, for a given efror probability, requires, on the average, approximately half the number of samples.
