MIAMI – A new device is offering fresh hope to stroke survivors, helping them regain strength and mobility in their arms and hands.
For millions of people who have lost the ability to perform simple tasks like dressing, eating, or hugging loved ones, this breakthrough could be life-changing.
Arlet Lara, a 50-year-old former math teacher, knows this struggle well. Several years ago, a stroke left her with debilitating weakness in her left arm and hand — the one she relies on for everyday activities like writing and eating.
“It has been a roller coaster of emotions. The stroke is a life-changing experience. As a math teacher, I would say it turned my life 180 degrees,” Lara said.
Now, thanks to a tiny implant, Lara is seeing improvement.
Dr. Robert Starke, co-director of endovascular neurosurgery at Jackson Memorial, explains that the device, called the Vivistim system, works by stimulating the vagus nerve in the neck. The electrode is connected to a small battery implanted in the chest, which helps enhance the effectiveness of physical therapy sessions.
“It can be turned on and off and specifically activated during therapy sessions to increase stimulation to the brain, which helps with coordination and movement in the upper extremities,” Dr. Starke said.
Lara is the first patient in South Florida to receive the Vivistim implant, and just a few weeks into her therapy, she’s already seeing positive changes.
“We hope she will go from limited function to nearly normal hand function, so she can carry out all her daily activities,” Dr. Starke added.
Lara describes herself as a “work in progress.” Her goals include writing and tying her shoes, but she remains optimistic that with the help of the device, her determination, and the support of her family, she will continue to improve.
“I’m eager to drive again, to eat with my left hand. I’m already holding a utensil. I’m clumsy, and I make a mess at home, but my family is very supportive and understanding,” she said.
The Vivistim Implant: How It Works The implant procedure is relatively quick, and patients typically go home the same day. While it can take 6 to 12 months to see significant improvements in strength and mobility, progress can continue for years afterward, giving patients like Lara hope for a brighter, more independent future.
