Study Voice Tremor in People Treated with Focused Ultrasound for Essential Tremor

(IRB#: IRB_00164533)

Essential tremor is when a part of a persons body such as a hand or arm is unsteady or shaky. Vocal tremor is when people may experience an unsteady or shaky voice. This condition may impact the mouth and throat muscles. This study will test whether people receiving focused ultrasound for treatment of essential tremors show improved voice tremors. People in this study will answer questionnaires and be observed for tremor in the face, jaw, tongue, and throat as well as using audio recordings and participant self-reporting. For those who are willing, the study will also examine the speech structures affected by tremors using nasoendoscopy (a procedure to look inside the throat and nose). Participation in the study requires some visits to a study clinic and completion of other activities will be done over the phone and online to track the health of participants.
