Helping Parkinson’s Patients Swallow Easier

While lodging at a Gainesville hotel during the filming of the hit movie Doc Hollywood in the fall of 1990, actor Michael J. Fox experienced his first symptoms of early onset Parkinson’s disease. Now, 15 years later, the Michael J. Fox Foundation for Parkinson’s Research has awarded UF Communication Sciences and Disorders Professor and Chair Christine Sapienza a $280,000 clinical discovery grant to examine the outcome of a strength-training program on the swallowing muscles of patients with Parkinson’s disease.
“Patients with Parkinson’s have difficulty swallowing and, as the disease progresses, the dysfunction gets worse and worse,” Sapienza says. “When you can’t swallow, you can aspirate—which can lead to a lung infection.” Aspiration pneumonia is the number one cause of death among patients with Parkinson’s, and while medications can help alleviate other symptoms of the illness, they do not substantially improve the muscles involved with swallow function. “While we are waiting for a cure for Parkinson’s, we need to help them deal with swallow dysfunction now and work to improve not only the quality of life, but longevity.”
Sapienza and colleagues Paul Davenport, a professor in the Department of Physiological Sciences, and Danny Martin, a professor in the Department of Physical Therapy, have developed a patent-pending handheld device that trains the expiratory muscles, and have created an accompanying training program that is easy to follow and complete at home. Once participants receive preliminary training on how to use the device, they are free to exercise with it on their own. “You can’t go to the gym and work out your breathing and swallowing muscles,” Sapienza says. “So this is basically a weightlifting device for your respiratory and swallowing muscles.”
From previous research completed by Sapienza and colleagues, the device is already known to improve expiratory muscle strength, toning the muscles needed for exhaling. The new grant will fund a two-year study to document whether the device also cross-trains the suprahyoid muscles used for swallowing.
Using x-ray technology, Sapienza and colleagues at the Gainesville VA Medical Center, Nan Musson and Jay Rosenbek, will record before and after images of participants’ swallow—capturing as many as 60 frames per second—to analyze whether strength training improves their ability to swallow. They will analyze swallow function during a variety of tasks, including the ability to swallow foods of different thicknesses. They also will examine other issues, including variability of swallow function in Parkinson’s disease.
The invention already has been tested on healthy adults, a subset of whom are musicians, as well as those with voice disorders and multiple sclerosis patients. Sapienza hopes, if proven effective, the device will be found applicable to a number of illnesses. “It’s Parkinson’s today, other neurological disorders tomorrow.”
