Objective

This is a single-center, open-label study designed to evaluate the feasibility, safety, and preliminary efficacy of cerebellar adaptive deep brain stimulation (aDBS) in adults with spinocerebellar ataxia type 6 (SCA6). A total of 5 participants will be enrolled.

Participants will undergo surgical implantation of deep brain stimulation (DBS) leads targeting the motor interposed nucleus of the cerebellum. The leads will be connected to one or two implantable pulse generators capable of delivering stimulation to deep brain structures and recording neural activity.

Participants will complete up to 18 in-person study visits over a 24-month follow-up period. During these visits, neural signals will be recorded under varying behavioral tasks and stimulation conditions.

Early study visits will be used to identify optimal stimulation parameters and neural biomarkers associated with disease state. These biomarkers will subsequently be used to implement adaptive DBS, in which stimulation amplitude is automatically adjusted in response to recorded neural activity.

Study outcomes will include assessments of safety and feasibility of cerebellar aDBS, as well as preliminary evaluation of its effects on clinical measures.

Participate in a study

Here are some general steps to consider when participating in a research study:

  1. Step
    1

    Contact the research team

    Call or email the research team listed within the specific clinical trial or study to let them know that you're interested. A member of the research team, such as the researcher or study coordinator, will be available to tell you more about the study and to answer any questions or concerns you may have.

    Get screened to confirm eligibility

    You may be asked to take part in prescreening to make sure you are eligible for a study. The prescreening process ensures it is safe for you to participate. During the prescreening process, you will be asked some questions and you may also be asked to schedule tests or procedures to confirm your eligibility.

  3. Step
    3

    Provide your consent to participate

    If you are eligible and want to join the clinical trial or study, a member of the research team will ask for your consent to participate. To give consent, you will be asked to read and sign a consent form for the study. This consent form explains the study's purpose, procedures, risks, benefits and provides other important information, such as the study team's contact information.

  4. Step
