Functional electrical stimulation (FES) involves the application of electrical current to the muscles or the nerve supplying the muscle of spinal cord injured individuals inorder to elicit a functional response. A number of researchers have used FES for the restoration of mobility in Spinal Cord Injured (SCI) individuals. However, the clinical application of FES for mobility in SCI individuals has been limited due to the complexity of the motor control problems and limitations of the FES hardware and controller software. At the University of Sydney we are currently trialing a new FES implant for the development of mobility. In order to develop practical mobility control solutions with this implant, accurate models of the movement response to FES must be developed. In my research I am applying genetic programming to the development of both the FES models and controllers. In this seminar I will introduce FES and the implant system we are using. I will then explain why and how I am applying genetic programming to this research problem, and what results have been obtained so far.
