Eligibility Criteria:
Inclusion Criteria:~* Provide informed consent~* Patient is over 21 years of age~* Patient has had a significant disabling, medication-refractory upper extremity tremor with no evidence of non-ET central nervous system disease or injury for at least three (3) months prior to implantation of Activa SC, PC, or RC device.~* Patient receives Vim electrode and Activa SC, PC or RC device implants, and recovers fully after surgery.~* Patient is available for study participation after their clinical programming appointments for six months.~Exclusion Criteria:~* Medication related movement disorders.~* Any suspicion of Parkinsonian tremor, including presence of Parkinsonian features such as bradykinesia, rigidity, or postural instability.~* Severe medical co-morbidity including cardiovascular disorder, lung disorder, kidney disease, continuous neurological disease, hematological disease, or frailty that impact tolerability of the surgery as judged by the screening physicians.~* Patient is undergoing a lead revision surgery.

- Gender: ALL
- Minimum Age: 21 Years
- Maximum Age: 90 Years
- Healthy Volunteers: f

Study Arms:
- Subjects with Essential Tremor (Type: EXPERIMENTAL): This cohort will receive deep brain stimulation (DBS) therapy responsively based on the level of their symptoms as detected by wearable EMG and inertia (acceleration) sensors.

Based on this trial design, predict the completion outcome and termination type (if applicable).
