About this trial
The objective of this study is to compare the effects of image-guided programming algorithm using various image segmentations vs standard clinical programming on reduction of tremor and patient satisfaction.

Trial outcomes
Primary outcomes
Tremor severity as measured by accelerometry
1\. The Xsens MTw Awinda accelerometer will be used to measure tremor severity. Measurements will be taken at baseline (DBS off) and after each stimulation setting. The accelerometry data can be objectively measured by quantifying the frequency and amplitude of the tremors and has been shown to correlate with the CRST.
Secondary outcomes
Clinical measure of tremor severity - CRST
Clinical measure of tremor severity - CRST
Other outcomes
3. Patient Global Impression of Change (PGIC) Scale
PGIC is a 7-point scale depicting a patient's rating of overall improvement. Patients rate their change as "very much improved," "much improved," "minimally improved," "no change," "minimally worse," "much worse," or "very much worse.
4. Quality of Life in Essential Tremor Questionnaire (QUEST)
The Quality of Life in Essential Tremor Questionnaire (QUEST) is a 30-item scale developed for patients with ET to measure the impact of ET on perceived quality of life (QOL), including activities of daily living that are affected by ET, such as the ability to read and write. The 30 items contribute to five scales: Physical/ADL, Psychosocial, Communication, Hobbies/Leisure, and Work/Finances. The score on each scale is expressed as a percentage of the total score possible, with a higher score indicating greater dissatisfaction with that domain of QOL
