Vagus nerve stimulation by electrical signals for controlling cerebellar tremor

摘要

A neurostimulator system for alleviating cerebellar tremor associated with multiple sclerosis, for instance, comprises a programmable electrical pulse generator. The programmable electrical pulse generator is programmed to generate electrical signals with the following parameters: a current magnitude of about 1 mA or less, a stimulation signal on-time to signal off-time ratio in the range of 2:1 to 1:1.8, signal on-times and off-times in the range of about 10 seconds to about 5 minutes, a signal frequency below 15 Hz, and a pulse width within the range of 50 μs to 300 μs. Other embodiments are disclosed and claimed.
