What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only This study
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study at Mayo Clinic will see if an Apple Watch can measure how well deep brain stimulation (DBS) controls essential tremor throughout the day. Fifty patients with DBS implants will wear the watch and perform simple tasks while the watch collects movement and heart data. The goal is to find better ways to monitor DBS effectiveness, not to test a new treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to better ways to monitor and adjust DBS therapy using wearable devices, improving tremor control.
What could go wrong
This is a small feasibility study with only 50 participants, so results may not apply to everyone. It's about measuring, not treating, so no direct health benefits.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 50 people

The number the study aims to enrol. It can still change while the study runs.

Started

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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.
