University of Virginia researchers are using ultrasound in place of traditional surgery, to help patients who have problems with hand tremors.
Researchers have found that ultrasound can be used to remove a tiny part of the brain that is responsible for the tremors, without the need for anesthesia or invasive brain surgery.
Fifteen people participated in the study, and all of them say they have seen improvement in their tremors. Four of the patients report that they could not complete certain tasks before the procedure, but can complete them now.
The most common side effects reported in the study were unsteadiness or tingling in face or fingers, but these resolved or were mild. One participant reported having a persistent, uncomfortable sensation in their dominant index finger.
