Interference reduction in nerve cuff electrode recordings-a new approach
نویسندگان
چکیده
A method is presented to reduce the interference pickup in nerve cuff recordings. The g,ains of differential amplifiers connected to the true tripole nerve cuff arrangement are tuned adaptively to null the residual EMG. Simulation results show that extraction of the neural signal is possible using this method without the need for high order filtering.

Adaptive Interference Reduction in Nerve Cuff Electrode Recordings
Neural signals (ENG) recorded from insulating cuffs fitted with electrodes and placed around nerve bundles may replace artificial sensors in providing feedback signals in functional electrical stimulation (FES) applications. Typical applications include correction of foot-drop, hand grasp in tetraplegic subjects and bladder voiding in certain types of incontinence. Unfortunately, the ENG signal...
متن کاملBioelectric field simulations for studying cuff-electrode interface errors
Ideally, interference in neural measurements due to signals from nearby muscles can be completely eliminated with the use of tripolar nerve cuff electrodes, in combination with appropriate amplifier schemes. In practice the cuff departs from its ideal model leading to cuff imbalance. As a result, the output nerve signal of such amplifiers has been widely reported to be degraded by interference,...
متن کاملSignal-to-noise Ratio of Nerve Signals Recorded with Full and Open Cylinder Cuff Electrodes
Ab-& In this paper, we compared the signal-to-noise ratios (SNRs) of nerve recordings obtained with an open cuff (a 270" cylinder) and a full cylindrical electrode (simulated by lifting the open electrode outside the solution) using an in vitro set-up. The thermal noise was considered as the main source of noise. The SNR with the open cuff was only 52*7% (n=3) less than that of a full cylindric...
متن کاملOn the Spectrum of Nerve Cuff Electrode Recordings
INTRODUCTION In the literature on recording of the electroneurogram (ENG) with nerve cuff electrodes, the influence of the contact configuration and cuff parameters on the amplitude density spectrum is hardly addressed. In contrast, in the literature on electromyography (EMG), the influence of the recording electrode configuration on the EMG spectrum is well recognized, including the dependency...
متن کاملWhole Nerve Recordings with the Spiral Nerve Cuff Electrode
The feasibility of whole nerve recordings from the hypoglossal (HG) nerve is demonstrated in acute cats using the spiral nerve cuff electrode. A good contact between the nerve and the electrodes, provided by the spiral nerve cuff due to its self-coiling property, should improve the signal-tonoise ratio. An instrumentation amplifier with very low input noise characteristics is also utilized. The...
