Promising tremor device study pulled before it began

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

Inclusion Criteria: * Clinical diagnosis of functional tremor diagnosed by a Mayo Clinic Florida movement disorders specialist. * Must have access to reliable internet video. Exclusion Criteria: * Cognitive impairment (Montreal Cognitive Assessment greater than 26). * Currently taking any of the following medications to treat tremor: primidone, gabapentin, zonisamide, any non-selective beta blocker, any benzodiazepine. * Exposure to tremorgenic drugs or drug with withdrawal states within 30 days prior to the study start. * Direct or indirect trauma to the nervous system within 3 months preceding the onset of tremor. * Known history of other medical or neurological conditions that may cause or explain subject's tremor, including, but not limited to: Parkinson's disease, dystonia, cerebellar disease, traumatic brain injury, alcohol abuse or withdrawal, mercury poisoning, hyperthyroidism, pheochromocytoma, head trauma or cerebrovascular disease within 3 months prior to the onset of essential tremor, multiple sclerosis, polyneuropathy, family history of Fragile X syndrome. * Prior MR-guided focused ultrasound or surgical intervention (e.g., deep brain stimulation, ablative thalamotomy or gamma knife thalamotomy). * Botulinum toxin injection in the 6 months prior to screening. * Use of medication(s) in the past month that might produce tremor or interfere with the evaluation of tremor, such as, but not limited to: CNS-stimulants, lithium, amiodarone, metoclopramide, theophylline, and valproate. * Regular use of more than two units of alcohol per day. * Sporadic use of a benzodiazepine, sleep medication or anxiolytic to improve sleep performance.
