Â鶹´«Ã½Physical Therapy and Dental Medicine research shows promise for people with Parkinson disease

Â鶹´«Ã½

A recently published study from student researchers at the Â鶹´«Ã½ showed that wearing a specially designed mouthpiece could improve symptoms for those suffering from Parkinson disease.

Â鶹´«Ã½Doctor of Physical Therapy Program Class of 2015 graduates Hillary Lane, PT, D.P.T., Megan Cutter Woodbrey, PT, D.P.T., and Lindsey Rose, PT, D.P.T., published the results of their study, titled “Exploring the Effects of Using an Oral Appliance to Reduce Movement Dysfunction in an Individual With Parkinson Disease: A Single-Subject Design Study." It appears in the January 2017 issue of the Journal of Neurologic Physical Therapy. The project was conducted in collaboration with David Arghavani, D.D.S., formerly of the Â鶹´«Ã½College of Dental Medicine, and Michael Lawrence of the Â鶹´«Ã½Motion Analysis Lab. It was supervised by Jim Cavanaugh, PT, Ph.D., in the Department of Physical Therapy and was funded by the Westbrook College of Health Professions.

To conduct the study, Lane, Woodbrey, and Rose used sophisticated equipment in the Â鶹´«Ã½Motion Analysis Lab to examine the gait, balance, and strength of an individual with Parkinson disease. In one condition, the participant completed several tasks while wearing a custom-made mouthpiece designed and fabricated with help from Arghavani. In the other condition, the participant completed the same tasks without the mouthpiece. The participant also wore the device for one month during his usual activities. The results showed that while wearing the mouthpiece, the participant experienced subtle improvements in walking, balance and strength. The study provided preliminary support for the idea that a custom-made mouthpiece might reduce some of the movement problems experienced by people with Parkinson disease. More rigorous and extensive research is most certainly needed to better understand the effect of the mouthpiece and the extent to which it might serve as a useful and practical intervention for people with Parkinson disease.
