1999 Annual Conference of the Biomedical Engineering Society. October 13-16, 1999. The system has been developed as a platform to investigate the effects of nonlinearities on posture adjustment capability and to explore strategies for using adaptive filters to improve system performance. The standing spinal cord injured subject is modeled as an inverted pendulum with a single degree of freedom. The simulation user operates a standard computer input device to differentially control the stimulation applied to a pair of muscles in order to balance the system model.
Visual feedback is provided by a real-time display on the computer monitor.
This simulation system is currently being used in studies to develop and evaluate improved systems for FNS standing and maneuvering. Eric Hartman J. J. Abbas Authors' email addresses are subject to change without notice. Contact the principal investigator if other addresses are invalid.
