Modified Wrist Model

The ¨Wrist Model¨ reported by Gonzalez in Opensim SimTK has 10 degrees of freedom and a total of 23 actuator muscles, with movement in the forearm, wrist, thumb (no flexion) and index. In order to evaluate the complete movements of a real hand in simulation, the model was modified to add the missing degrees of freedom to the thumb, middle, ring and little fingers. This more complete model is used for the simulation of the predicted movements of a hand motion classifier under Matlab for a virtual hand application. The tool ¨Computed Muscle Control¨ (CMC) was used to review the sequence of muscle excitations of these movements. Programs such as rhinoceros, paraview and notepad++ were used to modify figures in .vtp format to read opensim models.
