How to Enroll

If you’re interested in learning more about participating:

  1. Contact our team via email at contact@inwresearch.com or by phone at (509) 960-2818.

  2. A member of our team will answer your questions and explain the study in more detail.

  3. If appropriate, we can discuss next steps, including screening and eligibility requirements.

  4. You’ll receive a copy of the informed consent form and have time to review it and decide whether participation is right for you.

  5. If you choose to consent and are determined to be eligible, you may be invited to participate in the study.

Thank you for considering participation. Your involvement helps advance research and improve understanding of Essential Tremor disease.

Why Your Participation Counts

By taking part in a research study, you help scientists and physicians:

  • Learn more about how Essential Tremor begins, affects daily life, and progresses.

  • Test new treatments or approaches that may reduce tremors, improve daily functioning, and improve quality of life.

  • Improve quality of life for other people living with ET now and in the future.

Your involvement may also provide you access to additional monitoring, specialized care, and the satisfaction of contributing to meaningful research.

What Is Essential Tremor (ET)?

Essential Tremor is a neurological disorder characterized by involuntary, rhythmic shaking of parts of the body; most commonly the hands, but also the head, voice, legs, or trunk.


Some key facts:

  • ET is much more common than many people realize (it may affect 7 to 10 million Americans).

  • ET is not the same as Parkinson’s Disease, though it is sometimes confused with it.

  • Symptoms may worsen with age and may interfere with everyday tasks like writing, eating, or drinking.

  • Because ET varies widely from person to person, our understanding is still evolving.

Symptoms of ET

Movement-related symptoms:

  • Tremor in the hands or arms (most common)

  • Tremor of the head or voice in some cases

  • Tremor worsened by movement or when performing tasks

Impact on daily life:

  • Difficulty writing, eating, drinking or using tools

  • Challenges with fine motor tasks (buttoning clothes, tying shoes)

  • Emotional or social effect: frustration, self-consciousness, impact on work or hobbies

How Is ET Treated Today?

  • There is currently no known cure for ET. Research is working toward better understanding and novel treatments.

  • Treatment options aim to reduce tremor severity and improve function: medications, sometimes injections (e.g., botulinum toxin), and in select cases, surgery (e.g., Deep Brain Stimulation) may be considered.

  • Supportive therapies: occupational therapy, adaptive tools and devices, lifestyle adjustments (to compensate for tremor and its impact).

Who Can Join the Study?

Each research study has specific eligibility criteria. Generally, you may qualify if you:

  • Are an adult diagnosed with ET

  • Have tremor symptoms of a certain severity or in certain body parts (depending on protocol)

  • Are able to attend study visits and follow study procedures

  • Meet any study-specific exclusion criteria

Our study team will provide full eligibility criteria at screening. If you’re unsure whether you qualify, please contact our team.

What Does Participation Involve?

When you agree to join our ET research study, you can expect:

  1. Screening Visit: Review of your diagnosis, medical history, tremor symptoms, and medications.

  2. Baseline Visit: Detailed assessments, including tremor severity scales and functional tasks such as writing, drinking, etc.

  3. Follow-Up Visits: Monitor symptoms, treatment effects, and quality of life.

  4. Optional Procedures: Some studies may include additional tests or treatments.

Withdrawal: You may withdraw at any time without penalty, and your regular care will not be affected.

Benefits & Risks

Benefits may include:

  • Close monitoring by tremor-specialists and researchers

  • Access to investigational treatments

  • Contributing to scientific advances that may benefit you and others in the future

Risks may include:

  • Possible discomfort or side-effects from procedures or investigational treatments

All procedures, potential benefits, and risks will be clearly explained during the informed-consent documents.

Frequently Asked Questions

  • No. Study-related procedures and treatments are provided at no cost. Always ask if there are any reimbursements for costs related to participation.

  • That depends on the study design — your informed consent form will specify whether there is a placebo and how you’ll be assigned.

  • Yes. You may withdraw at any time without affecting your regular care.

  • Yes. Your current neurologist or tremor-specialist remains in charge of your regular care; the study team works in collaboration with your healthcare providers.

  • All data is handled securely and de-identified when possible. While absolute confidentiality cannot be guaranteed, strong safeguards are in place.
