Clinical Trial Summary

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.

Recruitment information / eligibility

• Status: Enrolling by invitation
• Enrollment: 50
• Est. completion date: August 2024
• Est. primary completion date: August 2024
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Patients with well-classified essential tremor, who are already receiving regular DBS therapy at Mayo Clinic for their movement disorder.

• Ability to understand study procedures and to comply with them for the entire length of the study and use study devices as outlined in protocol.

• Patient agrees to perform daily tasks in BrainRISE app and consents to the study collecting video and audio recordings during those tasks.

• Proficient in the use of a smart phone.

Exclusion Criteria:

• Cognitive or psychiatric condition rendering a patient unable to cooperate with data collection, or to manage and recharge smart watch and tablet computer devices.

• Presence of open or healing wounds near monitoring sites (infection risk).

• Inability or unwillingness of individual or legal guardian/representative to give written informed consent.

• Tremor

Intervention

Device:
• Apple Watch
The smartwatch will collect data including accelerometry, heart rate, activity, move time, exercise time, stand time, steps, walking and running distance, heart rate variability, respiratory rate, six-minute walk, and flights climbed. During sleep, the smartwatch will collect daily nighttime physiologic data such as time in bed, average sleep time, sleep efficiency, wake after sleep onset, nocturnal heart rate, and nocturnal respiratory rate.

Other:
• BrainRISE app
The app will play a prerecorded video, which will walk participants through tasks which include holding your arms in different postures, repeating different vowel sounds and phrases as prompted, and tracing different patterns on the phone screen. The tasks are video and audio recorded while being completed. Completing the tremor assessment tasks will take about 10 minutes.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Acquire high-quality physiological signal characteristics from movement disorder patients.	Acquisition of high-quality physiological signals from 50 subjects with movement disorders over the course of two weeks and up to thirty subjects over one day with 90% compliance rate as determined by the number of study tasks completed by participants.	12 Months
Primary	Acquire high-quality physiological tremor signals from movement disorder patients.	Measured by wrist accelerometry, which tracks the acceleration of the patients' wrists and is reported in m/sec^2 on a scale where 1.0 = 9.8m/s^2.	12 Months
Secondary	Subject feedback	Subject comfort, compliance, and convenience during the data collection as determined by a post-study assessment asking patients to rate their experience on a scale of 1-5 from hardest and most inconvenient to easiest and least inconvenient.	12 Months
