Abstract

Functional electrical stimulation has been tested previously for the suppression of pathological tremor. Typically, the tremor is detected using motion sensors, and the stimulation is delivered supra motor threshold activating muscles to oppose the tremulous oscillations. Here we present a novel system that estimates tremor from the recorded electromyography signals and delivers stimulation below the motor threshold, activating sensory nerve fibers. The hypothesis (backed up by the previous studies) is that the generated sensory inflow will modulate the sensory feedback loops and/or project to the supraspinal centers acting on the true tremor sources/generators. The system was tested in two patients suffering from Parkinson disease and one Essential tremor patient, and the results were promising, i.e., tremor was significantly attenuated.
