About the trial

What the trial wants to find out

The purpose of this research is to observe the daily loss of benefit from DBS therapy by performing a standardized set of tasks throughout the day while wearing an Apple Watch to collect movement and other physiological data.

The group in the trial

  • Wearable device for tremor assessmentTreatment being tested

    Subjects already implanted with a deep brain stimulation (DBS) system for therapy for essential tremor wear an Apple Watch and complete tremor assessment tasks detailed through the BrainRISE app four times a day for two weeks.

    Treatment: Apple Watch and BrainRISE app
