Wearable Sensor for Responsive DBS for ET

The purpose of this study is evaluate the effectiveness and safety of a possible new treatment for Essential Tremor (ET) using external wearable sensors, which have the capability of recording acceleration and Electromyography (EMG). This therapy is called Responsive Deep Brain Stimulation (R-DBS). R-DBS systems will communicate with a computer, and apply stimulation when the computer detects patterns associated with tremor. This detection will suppress pathological activity and improve or alleviate the tremor. Currently, DBS is approved for the treatment of ET; however, stimulation is delivered continuously even when tremor or other symptoms are absent. Continuous DBS can lead to unwanted side effects such as stuttering and gait\\balance problems. On the other hand, R-DBS will turn on only if activity associated with ET from the external sensors is detected.
