ET Stigma Response to Tremor Suppression
What this study is about
Essential Tremor (ET) is prevalent, affecting approximately 3% of the adult population. Involuntary shaking of the hands during action is a prominent feature, interfering with feeding and writing and other manual tasks.
View original scientific description
Essential Tremor (ET) is prevalent, affecting approximately 3% of the adult population. Involuntary shaking of the hands during action is a prominent feature, interfering with feeding and writing and other manual tasks. The involuntary movement is visible to observers, some of whom misinterpret the shakiness as manifestation of anxiety or instability, while some other observers attribute it to alcohol or drug use. The psychological effects of resulting stigma on quality of life for people with ET can rival the physical difficulties caused by the condition. For this study, we propose to measure 1 year after effective tremor suppression following thalamotomy with high intensity focused ultrasound changes from baseline in psychological distress and social dysfunction related to ET stigma, and to correlate change from baseline with improvement in functional status related to tremor and in objective measures of tremor severity. We hope to discover that ET stigma is largely reversible when tremor is effectively treated, and we aim to learn what degree of tremor suppression correlates with substantial psychological relief. We will also determine if ET stigma is predominantly helped by unilateral dominant-hand treatment, or if the second side treatment is necessary to accomplish most benefit.
Interventions
PROCEDURE
stereotactic thalamotomy with focused ultrasound
stereotactic thalamotomy with high intensity focused ultrasound, guided by four-tract tractography
Primary outcome measures
ET stigma psychological distress
Time frame: change from baseline before thalamotomy to 12 months after thalamotomy
Psychological distress related to other people's reaction to their tremor.
ET stigma social dysfunction
Time frame: change from baseline before thalamotomy to 12 months after thalamotomy
Social avoidance and maladaptive behaviors related to other people's reaction to tremor.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
