Principal Investigator: Wendy M. Murray, PhD Co-Principal Investigator: Richard F. Weir, PhD Project Category: Other - 2005 Objective: The specific aim of this work is to embed a musculoskeletal model of the upper extremity in the controller of a multifunction prosthetic hand. Research Plan: In this development project, we propose to use a biomechanical model of the upper extremity to provide a link between individual forearm muscle activity and the motors of an artificial hand. We will use myoelectric (EMG) signals of the extrinsic muscles of the hand as inputs to a forward dynamic simulation of natural hand and wrist motions. The output of the simulations (joint angles, velocities, accelerations, and muscle forces at the wrist, thumb, and fingers) will, in turn, be used to control the associated joints in a multi-function hand prosthesis. Work Accomplished: We were notified that this project received a fundable score in January 2006. We have completed all administrative items requested and we are awaiting funding to initiate this project. Expected Outcome: We aim to develop a novel control algorithm for multifunction artificial hands based on forward dynamic simulation of the intact biomechanical system.
