Biomechanical Model of the Human Arm
Overview
A biomechanical model of the human arm has been developed to aid in the design
and analysis of controllers for functional electrical stimulation (FES) of
paralyzed muscles.
The model includes the muscles of the elbow, forearm and wrist that tend to become paralyzed in C6-C7 spinal cord injuries, leaving voluntary control of shoulder and scapular motion relatively intact and suitable for use as command signals.
The model represents an average adult arm and is based on data from cadaver measurements reported in the literature and scaled to a single, mean arm size. Particular emphasis has been placed on the accuracy of parameters that are important for control, including the moment arms for muscles that act on multiple degrees of freedom and the range of sarcomere lengths over which each muscle operates.
Sharing and upgrading the model are facilitated by the use of popular modeling and simulation environments. The final model runs in Simulink simulation environment.
