Christopher Watts, Ph.D. – Research

Parkinsonology

The overarching goal of this line of research is to expand human knowledge of how Parkinson’s disease (PD) effects laryngeal function in voice and swallowing to inform the development of more effective treatments to rehabilitate and/or sustain those functions. We are specifically interested in how voice and swallowing impairments manifest in different clinical phenotypes (e.g., subtypes) of PD. Our research investigates how voice and swallowing are influenced by PD tremor phenotype (e.g., tremor dominant vs. non-tremor dominant), age of onset (e.g., late onset vs. younger onset), sex, and years post-onset. A major aim of this research is to increase our understanding of how and why laryngeal function in voice and swallowing is impaired heterogeneously (differently) across the large population of people with PD.

Treatment Outcomes for Voice Disorders

The overarching goal of this line of research is to measure the effectiveness of treatments for voice disorders so that clinicians have access to research which might inform their evidence-based practice. Most recently, we have focused on the effectiveness of Stretch-and-Flow voice therapy, an approach which centers on the control of airflow during speech as a foundation upon which to rebalance the vocal subsystems. This line of applied research utilizes clinical trials and small group designs to measure clinical outcomes after a period of voice treatment (typically 6 to 8 weeks).  A major aim of this research is to determine which treatments provide a meaningful benefit to patient quality of life, improvement in physiological function, and enhancement of perceived communication effectiveness.

Instrumental Measures of Voice and Swallowing

The overarching goal of this line of research is to explore the utility of instrumental measures of voice and swallowing physiology within the context of clinical assessment and treatment. We utilize acoustic, aerodynamic, and electrophysiological instrumentation to assess how the larynx and associated structures function during voice production and swallowing. These measurements are obtained both before and after voice or swallowing treatments. A major aim of this research is to determine which instrumental measures effectively and validly capture changes in physiological function post-treatment.

Watts (Ph.D., Univ. of South Alabama) is the Director (Chair) of the Davies School of Communication Sciences and Disorders in the Harris College of Nursing & Health Sciences at TCU, where he also holds the appointment of tenured Professor. Prior to his arrival at TCU in 2008, Dr. Watts held faculty appointments at James Madison University, the University of South Alabama, and the University of Central Florida. His clinical, research, and teaching interests center on laryngeal function in voice and swallowing, with an emphasis on laryngeal physiology in Parkinson’s disease. Dr. Watts regularly publishes research in the top peer-reviewed scientific journals of communication sciences & disorders, and presents his research at national and international conferences.

Dr. Watts is known for his mentorship of students and quality of research. He has been recognized with the Wassenich Award for Mentoring at TCU, and was twice recognized with the Dean’s Award for Research. His outstanding contributions to research, teaching, and service to the profession were recognized by election as Fellow of the American Speech-Language-Hearing Association in 2015.

In the Davies School of COSD, Dr. Watts teaches graduate courses in Voice Disorders and undergraduate courses in Speech & Hearing Science. He also collaborates in the Voice Clinic on the campus of TCU, a specialty program within the Miller Speech & Hearing Clinic. Dr. Watts has established collaborative relationships with national and international colleagues. His ongoing collaboration with Dr. Ted Mau and his team at the UT Southwestern Medical School has resulted in important clinically focused research utilizing high quality research designs.

Christopher Watts – Overview

2019-03-05T18:12:37-06:00

OVERVIEW

Welcome to the Laryngeal Function Lab – the primary research and teaching lab of Dr. Christopher R. Watts. The purpose of the Laryngeal Function Lab is to create new knowledge and expand existing knowledge related to our understanding of laryngeal function in voice and swallowing with the goal of improving diagnostic and treatment approaches for individuals with laryngeal impairments.  Along with my team of collaborators and students, we investigate laryngeal function in normal and dysphonic (voice impairment) populations and also those with normal swallowing and dysphagia (swallowing impairment).  Recently we have developed an innovative line of research investigating how clinical subtypes of Parkinson’s disease differently impact laryngeal function in voice and swallowing.

The lab is housed within the Miller Speech and Hearing Clinic on the campus of Texas Christian University.

In my program of research I use acoustic, aerodynamic, and electrophysiological technologies to measure laryngeal function during voice production and swallowing. The laryngeal function lab utilizes state-of-the-art technology including:

  • Laryngeal Videostroboscopy
  • Acoustic & Aerodynamic Voice Analysis systems
  • Electromyography and Manometry
