Re: Dissertation Defense for Talah Wafa

It is my pleasure to announce that Talah T. Wafa, a Ph.D. candidate in the Department of Hearing, Speech and Language Sciences, will defend her dissertation on “A new paradigm in assessing postural stability” on Thursday, July 11th at 10:30 a.m. in College Hall, Room 318. The first forty minutes of the dissertation defense are open to the Gallaudet community.

The purpose of Dr. Wafa's study is to assess the limits of stability (LOS) in a group of healthy volunteers and compare them against the theoretical limits of stability.  Adjusted sensory organization test equilibrium scores (SOT) were then calculated using each participants’ personal LOS to determine significant differences in postural stability scores using both the theoretical and personal limits of stability measures. This study shows personal LOS is a dynamic variable that is affected by mobility and agility, which should be measured routinely as part of a comprehensive balance assessment. In addition, the personal LOS should replace the theoretical LOS in the calculation of SOT equilibrium scores when determining an individual’s risk for fall.  Use of an individual’s personal LOS would undoubtedly result in personal SOT equilibrium scores that better represent multiple aspects of an individual’s personal postural stability and translate a more accurate representation of their discrete postural stability and unique fall risk.  

The members of Dr. Wafa’s dissertation committee are Dr. Matthew H. Bakke, Department of Hearing, Speech, and Language Sciences, co-chair of the dissertation committee; Dr. Carmen C. Brewer, National Institute on Deafness and Other Communication Disorders, National Institutes of Health, co-chair of the dissertation committee, Dr. Chizuko Tamaki, Department of Hearing, Speech, and Language Sciences; Dr. Dragana Barac-Cikoja, Department of Hearing, Speech, and Language Sciences (retired); and Dr. Christopher K. Zalewski, National Institute on Deafness and Other Communication Disorders, National Institutes of Health.

Dr. Wafa began the PhD in Audioligy Program after earning a clinical doctorate in audiology (Au.D) at Gallaudet University.  She has been involved in several research projects investigating the vestibular phenotype in genetic conditions such as NF2 and Usher syndrome. In 2016, she received a postdoctoral research training award from the National Institute on Deafness and Other Communication Disorders (NIDCD) focusing on assessing the vestibular and balance systems of both humans and mice. She has presented at scientific meetings and coauthored several research articles.

Please join me in extending best wishes to Dr. Wafa for her dissertation defense.
