On Wichita State University Week: Your tongue matters more than you might think.
Heidi VanRavenhorst-Bell, chair and associate professor in the Department of Human Performance Studies, explores why.
Faculty Bio:
Dr. Heidi VanRavenhorst-Bell has an established interdisciplinary line of research in clinical exercise physiology and orofacial myology. Her work in promoting healthy tongue muscle performance through physical activity has been internationally recognized and showcased on NPR’s Science Friday with Ira Flatow. Her research also includes R&D and product validation in the health & fitness industry. Dr. Bell has developed a systematic network purposed toward bridging the gap between healthcare and fitness. Her entrepreneurial background has further led to three start-up companies, secured intellectual property and established a platform to mentor students aspiring to be the next leaders in the field. Besides serving as Chair and Associate Professor of the Department of Human Performance Studies at Wichita State, Bell is the undergraduate coordinator for Exercise Science, manager of the Human Performance Laboratory, a Faculty Fellow for the Dorothy and Bill Cohen Honors College, and an affiliated faculty member in the Department of Biomedical Engineering.
Transcript:
Eight muscles. One tongue. And it might be the hardest-working muscle group you never think about. That is, unless you bite it. The tongue helps us speak, chew, swallow, and even keep the airway open during sleep. But for more than one in three people, tongue and facial movement patterns don’t work as efficiently as they should—what clinicians call orofacial myofunctional disorders, or OMD.
Here’s the tricky part: in clinic, tongue performance measures are often recorded with tools that capture only a slice of what the tongue does. One challenge is slippage of the oral device within the mouth. The tongue’s anterior and posterior have different muscle fiber composition and functional roles, so even small shifts can change what’s actually measured. We tested and patented an oral-safe anti-slip patch, and participants reported better stability without meaningful changes in the pressure values, which is clinically important. Another area of consideration during assessments is head posture. Research shows even the simplest change in position may shift lingual measures.
Measuring tongue motion and force in real life—not just during brief clinical visits—presents challenges, too. PARROT, a patented research prototype, could address this. Fitting like a palatal mouthpiece, it wirelessly captures spatial positioning of the tongue within the oral cavity, while also mapping how hard and for how long the tongue is pressing against various structures. The scientific goal? Attain objective, repeatable data that can improve screening, guide therapy, and support telepractice.
A deeper physiology question involves fascia, which links human body structures from the tip of the tongue down the tips of the toes. Manipulating fascia and other physiological factors through physical activity and targeted stretching are shown to favor tongue strength or endurance.
So, the next time you swallow, yawn, talk or even exercise… remember: your tongue is doing a quiet biomechanical ballet.
