Scientists at the University of Maryland have shown that focused ultrasound can reduce tremor and improve mobility in patients with Parkinson’s disease. Research published New England Journal of Medicine.
The study included 94 patients with Parkinson’s disease. They were randomly divided into two groups: participants in the control group underwent a sham procedure and those in the experimental group received ultrasound therapy without incision using the Exable Neuro device.
After three months, symptoms improved in 32% of patients in the control group and 70% of patients in the experimental group. For most, the effect of the procedure continued a year later.
Symptoms of Parkinson’s disease include tremors, stiffness, and difficulty with balance and coordination. Sometimes deep brain stimulation (DBS) with surgically implanted electrodes is used for treatment. The procedure carries a small risk of serious side effects, including brain hemorrhage and infection. The scientists’ technique does not require an incision and the patient is conscious during the procedure.
The study was funded by Insightec, manufacturer of Exable Neuro.
