At-home taVNS for Neurorehabilitation in Parkinson's Disease

United States16 participantsStarted 2026-06-01

Plain-language summary

The goal of this clinical trial is to learn if taVNS works to treat symptoms of Parkinson's Disease in adults. It will also learn about the feasibility and preliminary efficacy of taVNS administered at home by the participant. The main questions it aims to answer are: 1. Is at-home taVNS feasible and effective for treating symptoms of Parkinson's Disease? How often are participants completing the stimulation protocol? What are the side effects of stimulation experienced by participants? How do participants rate the experience of taVNS sessions at home? How do participants' scores on assessments and questionnaires change with taVNS treatments? 2. How does taVNS impact connections between neural networks in the brain of patients with Parkinson's Disease at rest? Participants will: * Have a baseline MRI scan to take images of their brain. * Complete a series of assessments and questionnaires to evaluate their Parkinson's Disease motor symptoms, cognitive and neuropsychiatric symptoms, and other non-motor symptoms. * Have an initial taVNS session where their threshold to perceive the stimulation will be measured. This value will be used to stimulate each participant at a specific dose relative to their individual perception of stimulation. * Be trained on how to use the taVNS device and system and have one 1-hour taVNS session where their vitals will be monitored. * Self-administer 1-hour daily taVNS sessions for 8 weeks at-home, complete tolerability questionnaires, and weekly remote check-ins with study staff. * After 4-weeks of at-home taVNS, participants will come in-person to repeat the questionnaires and assessments from the first visit. * Following the 8 weeks of taVNS sessions, participants will repeat the MRI scan, assessments and questionnaires from visit 1. * Participants will complete questionnaires remotely 1 month following their last taVNS sessions.

Inclusion Criteria: * Issues with walking, balance, and gait as determined by a movement disorders neurologist (a score of equal to or greater than 1 on MDS-UPDRS items 2.12 (walking and balance), and 3.10 (gait)) * Diagnosis of idiopathic Parkinson's Disease based on UK Brain Bank diagnostic criteria * Hoehn and Yahr Stage 2-4 as determined by a movement disorders neurologist * Stable on dopaminergic medications over the past 30 days prior to enrollment in the study Exclusion Criteria: * A history of taVNS in the last 6 months * A history of brain surgery, traumatic brain injury or stroke * Diagnosis of a nervous system disorder besides PD, alcohol or substance use disorder, or unstable cardiovascular conditions * History of myocardial infarction or arrhythmia, bradycardia * A history of other significant gait impairment unrelated to PD (e.g. orthopedic deformities) * Inability to complete gait/ motor assessments (without assistance or assistance devices) * Ear trauma, facial pain, anatomical abnormalities or other barriers preventing earpiece fit * Failure to meet all criteria on a standardized MRI/taVNS safety screening: This includes, but is not limited to, the presence of claustrophobia, implanted electronic devices that are not 3T MRI compatible (e.g., pacemakers), metallic objects or fragments (e.g., bullets), and non-removable hair clips or piercings. * Individuals with a diagnosis of cognitive impairment (MoCA \< 24) that would make them unable to understand and f…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
