Pittsburgh Review

In Pittsburgh, a new medical procedure offers promising results for stroke recovery. Neurologic injuries from strokes affect nearly 800,000 Americans each year, often leading to lost motor functions. A fresh therapeutic approach at Allegheny Health Network's (AHN) Allegheny General Hospital is providing hope for patients to regain control of their arms and hands.

The Vivistim Paired Vagus Nerve Stimulation (VNS) System, approved by the FDA, aids stroke survivors by transmitting light electrical impulses to the vagus nerve. This nerve extends from the brainstem through the neck and into the body. Stimulating it may help form new brain pathways, potentially enhancing strength and function more quickly than standard rehabilitation alone.

Alexander Whiting, MD, a neurosurgeon and the director of epilepsy surgery at AHN's Neuroscience Institute, spearheaded the first use of this procedure for stroke recovery in Western Pennsylvania. "The VNS implant acts like a ‘turbo boost’ for the brain," Dr. Whiting stated, emphasizing the technology's ability to accelerate the natural recovery process. He noted, "This is the first time we’ve been able to significantly change the trajectory of stroke recovery beyond the standard rehabilitation timeline."

Scott Pavlot, 66, from Wexford, Pennsylvania, is among the initial patients to undergo the procedure. Following an ischemic stroke on February 12, 2024, Pavlot experienced severe left-side paralysis. His stroke coincided closely with his birthday when he received a new bass guitar. "I got a brand-new bass for my birthday and only got to play it for one day before the stroke," Pavlot recalled, expressing his determination to maximize his recovery with the Vivistim treatment.

Traditional stroke rehabilitation relies on repetitive exercises to invoke brain neuroplasticity, which naturally facilitates self-rewiring. However, many patients experience a stagnant recovery after two to three months, a challenge this new system aims to overcome. The Vivistim System involves implanting a pacemaker-like device in the chest, connected via a wire to the vagus nerve in the neck. Patients can activate the device during therapy or everyday activities.

Since his operation in September 2024, Pavlot regained movement and strength in his left arm and hand, allowing him to play music again. "The difference has been huge," he remarked about his improved hand control. Dr. Whiting noted, "Once the device is implanted, patients use a handheld magnet to activate it during rehabilitation exercises and daily activities."

The American Stroke Association reports that ischemic strokes result from an obstruction in the blood vessels supplying the brain. It accounts for around 87% of strokes. For patients who have lost arm and hand mobility, this advancement empowers them to regain self-sufficiency and hope. "For many stroke survivors, losing function in their hand means losing their ability to feed themselves, dress, or do the things they love," said Dr. Whiting.

Reflecting on his progress, Pavlot emphasizes the importance of perseverance. "You can’t be defined by a stroke," he stated. "This isn’t the end of my story — it’s just a new chapter."
