Abstract Details

2011, Doctor of Philosophy, Case Western Reserve University, Biomedical Engineering.
A flat interface nerve electrode (FINE) is a type of nerve cuff electrode designed to increase spatial selectivity by reshaping a nerve and realigning fascicles inside the nerve trunk. FINE has shown improved fascicular and subfascicular selectivity enabling the activation of many muscles with a single electrode. Despite significant improvement in the spatial selectivity of FINE, a motion control algorithm for Functional Electrical Stimulation (FES) using a FINE has not yet been developed, due to the inherent complexities in neuromuscular skeletal systems and the nerve-electrode interface. In this study, a novel motion control algorithm is presented to overcome these difficulties. The proposed control method does not require an analytical model of the system being controlled. Therefore, this control method is suitable for FES control with a FINE, because finding an accurate model with FINE is extremely difficult. In order to test the performance of the control algorithm, a computational model of the human ankle joint system was developed along with a finite element model of the sciatic nerve. The results indicate that both the ankle and subtalar joint motion could be controlled using a twenty-contact FINE on the sciatic nerve. The proposed controller was also tested in an acute rabbit experimental study, and the result showed good reference trajectory tracking performance within 10% average RMS error. The results in both computational simulation study and animal experiment study show that this novel control method is suitable for the system where a model is not available and where the feedback signals are difficult to obtain.
