Fatigue effects in muscular control

Abstract

A muscular control model is examined in order to determine possible fatigue effects on the monosynaptic reflex. The muscle dynamics and neural spindle receptors are represented in standard fashion as 4-element viscoelastic models. A theoretical derivation of the afferent spindle output is given. This afferent information from the muscle-spindle and delay effects are incorporated into the feedback loop. Fatigue effects upon system performance and stability are illustrated by means of numerical simulations.<>
