Abstract :
A simple model representing the quasistatic behavior of skeleton muscle in which the force produced by the muscle is a bilinear function of the muscle length and the neural activation of the muscle is presented. Using two such muscles to represent the biceps and triceps, a biomechanical model of the elbow and forearm is developed. Predictions for the quasistatic maintenance of posture are given. The competence of this model is assessed on the basis of preliminary experimental data
