Prisma Health announced this week it now offers focused ultrasound treatment for patients with medication-refractory essential tremor and Parkinson’s disease.
“We’re proud to be the first and only health care system in South Carolina offering this innovative procedure,” said Dr. Erwin Mangubat, chief of neurosurgery at Prisma Health Richland Hospital in Columbia. “This technology allows us to deliver transformative results quickly and safely. It's incredibly rewarding to see patients and families experience such joy.”
Prisma Health neurosurgeons utilize high intensity sound waves—with no surgical incisions—to precisely target deep brain pathways that cause tremors. Each session is performed under Magnetic Resonance Imaging (MRI) guidance allowing for precise targeting, real-time temperature monitoring and immediate confirmation of results. Many patients experience rapid improvement with minimal complications and return home the same day. Mild side effects such as mild numbness, imbalance or headache will typically resolve within days to weeks.
Keith Penwarden, 68, from Leesville, South Carolina, is among the first patients in the state to receive the treatment. He has lived with essential tremor affecting both sides since first developing symptoms at age 50. He describes it as a challenge that affects everyday activities such as filling water bowls for his pets and his ability to hold anything steady in his hands. When he was able to hold a cup of water in his right hand immediately after treatment, “I was shocked. I’ve taken medicines over the years that barely made a difference. Now I can lift a water pitcher with one hand. I hope this can help a lot of people.” Penwarden looks forward to having a second treatment in a few months for his left side.
Focused ultrasound was approved by the U.S. Federal Drug Administration (FDA) in 2022 to treat both sides of the body for patients with essential tremor. Patients may receive treatment on the second side after waiting at least nine months following their first session. Studies show durable tremor reduction lasting for years. This incisionless option is ideal for individuals who have tremor that doesn’t respond to medications, who take blood thinners, are not candidates for deep brain stimulation (DBS), or prefer to avoid brain implants.
