Description

Functional Electrical Stimulation (FES) is a technique for restoration of lost motor functions of paralyzed muscles. The authors have been studying a creation method of stimulus data by using Artificial Neural Network (ANN) which mimics the musculoskeletal system of paralyzed patients. "Direct inverse modeling" that we adopt as a learning method of ANN cannot be applied to a redundant object such as the musculoskeletal system. Hence a constraint is used for the resolution of kinematic redundancy. In this paper, we study the performance of the constraints with a musculoskeletal simulator that includes synergistic and/or antagonistic muscles.
