A new study shows that pulses of minimally invasive ultrasound waves improve the quality of life for people living with Parkinson's disease by immediately and significantly reducing tremors.

The study involved a minimally invasive procedure that offers significant benefits over some other treatments that carry higher risks.

Dr. Federico Bruno, a radiologist in the Department of Biotechnological and Applied Clinical Sciences at the University of L'Aquila in Italy, led the research.

The procedure uses a technology called magnetic resonance-guided focused ultrasound (MRgFUS) that works by focusing sound energy beams to eradicate a small part of the thalamus in the brain.

Although a procedure called deep brain stimulation has been successful in some people, it carries potential risks, such as bleeding and infections.

Deep brain stimulation requires a surgical procedure, which involves a surgeon implanting a small electrode into the brain. The implant connects with a pacemaker-like device in the chest.
