Abstract

In this paper, a four-segment musculoskeletal model of the floor and legs is created in AnyBody in which are considered all the muscles and ligaments of the leg and foot. To obtain input this dynamic problem (ground reaction force and path components in the foot during walking) on subjects with normal foot motion analysis and force plate testing has been done. To solve the model and determine the muscle forces is used of the two criteria min-max optimization and fifth order polynomial. For validation, Electromyography testing has been done on the subject. The review results be determined that the min-max optimization criteria than fifth order polynomial optimization criteria estimates closer approximation to the actual muscle activity estimates. Modeling with both criteria min-max and fifth order polynomial, in the anterior tibia muscle activation patterns are weaker than other
