Our lab conducts research investigating the essential characteristics of oral, pharyngeal and laryngeal motor function as they relates to swallow function across the lifespan in healthy individuals and individuals with various disorders. We are also engaged in treatment efficacy studies. Our studies focus on the following research questions:
- How does oral motor strength and endurance change throughout the lifetime in healthy individuals?
- Do changes in oral motor strength and endurance result in changes in swallow performance?
- What is the impact of OPMD, a rare disease with a high incidence in New Mexico, on oral, pharyngeal and laryngeal function as it relates to speech, voice and swallowing?
- Can we find ways to successfully slow or halt the effects of OPMD on oral, pharyngeal and laryngeal function?
- Is stability a good measure of oral motor function and is it more sensitive to age and/or disease than our current measures?
- What is the efficacy of standard swallow treatments in patients with OPMD?
- Can Pharyngeal Constriction serve as an estimate of pharyngeal strength?
- What is the effect of OPMD on laryngeal movement and voice?
- What is the time course of swallowing, voice and speech deficits in patients with OPMD?
- What is the efficacy of botox as a treatment of UES dysfunction in patients with OPMD?
