Conditions
Summary
The purpose of this clinical trial is to learn about the Tremor Retrainer smartphone application and Simplified Functional Movement Disorder Rating Scale in patients with functional tremor. The main questions the study aims to answer are: 1. Is the Tremor Retrainer application usable for patients and are there signs that it can help functional tremor? 2. Can a televideo administration of the Simplified Functional Movement Disorder Rating Scale give enough information to use this scale via televideo in future studies?

Interventions
The Tremor Retrainer smartphone application uses the smartphone's built-in accelerometer to calculate a patient's tremor frequency when the smartphone is strapped to the patient's wrist. The application will provide auditory cues to the patient with a treatment frequency at 2/3 the patient's baseline tremor frequency for half a session, then 1/3 the patient's baseline tremor frequency for the second half of the session. Meanwhile, oscillatory movements will be continuously analyzed with frequency calculated and displayed relative to goal frequency, so that the patient receives continuous feedback via a visual dial as to whether they are meeting treatment goals. Intervention will consist of a one-week Tremor Retrainment Protocol.
