Stability of chronic intrafascicular electrode recordings

Abstract

Intrafascicular electrodes have been implanted in peripheral nerves of cats and have recorded neural activity from a small population of nerve fibers for as long as six months, suggesting that these electrodes can be used on a chronic basis to acquire information about limb position, muscle force and skin contact. Preliminary results suggest that the activity of a small population of nerve fibers can be reliably monitored on a long-term basis using intrafascicular electrodes. They appear to cause little or no permanent damage and so may be suitable for use in an functional neuromuscular stimulation feedback system.< >
