Abstract

It is widely accepted that neural systems for controlling cyclic movements such as walking, running, chewing, and breathing utilize pattern generating neural circuitry. A network of coupled pattern generator units may be used to control such movements in multisegmented skeletal systems. In the work presented here, we use a network of coupled pattern generators as one component in a control system for generating movements using electrical stimulation. The control system is intended for eventual use in Functional Neuromuscular Stimulation (FNS) systems to restore locomotor function to individuals with neurological disorders. Results of computer simulation studies are presented to demonstrate that: (1) the pattern generator component can generate oscillatory patterns over a wide range of model parameter values; (2) the coupling amongst individual pattern generator components can be automatically adjusted to generate specified intersegmental phase lags; and (3) the control system can automatically adjust stimulation parameters to generate a specified movement of a multi-segmented skeletal system.
