Evaluation of Voice and Voice Disorders: Laryngeal Function Studies

presented by Julie Barkmeier-Kraemer PhD

Accreditation Check:

In 2016, the American Speech-Language-Hearing Association (ASHA) working group on Instrumental Voice Assessment Protocol (IVAP) completed their recommendation of the minimum voice evaluation instrumental methods and measures to be completed during a standard voice evaluation. These recommendations included methods for completing acoustic and aerodynamic measures typically coded as Laryngeal Function Studies (CPT 92520).The focus of this course is to provide a summary of the ASHA IVAP recommended instrumental laryngeal function studies methods and measures. In addition, low tech approaches for conducting acoustic and aerodynamic measures will be presented for those clinicians without access to high tech equipment.

  • Julie Barkmeier-Kraemer PhD, CCC-SLP

    Julie Barkmeier-Kraemer, PhD, CCC-SLP is a speech-language pathologist and professor in the Division of Otolaryngology, Clinic Director for the Voice Disorders Center, and Adjunct Faculty to the Communication Sciences and Disorders program at the University of Utah. Dr. Barkmeier-Kraemer received her M.A. and Ph.D. degrees from the Department of Speech Pathology and Audiology at the University of Iowa and completed postdoctoral work in the area of neurolaryngology with Dr. Christy Ludlow at the National Institutes of Health. Prior to joining the faculty at the University of Utah, Dr. Barkmeier-Kraemer served in the Department of Speech, Language, and Hearing Sciences faculty at the University of Arizona (1997-2011), after which she joined the Neuroscience Graduate Group as well as the Voice-Speech-Swallowing Center team in the Department of Otolaryngology at UC, Davis (2011-2014). She has served on several ASHA committees, including as a past coordinator for ASHA’s SIG 3: Voice and Voice Disorders, during which time she contributed to the development of the Consensus Assessment Protocol for Evaluation of Voice (CAPE-V) and the Classification Manual for Voice Disorders. She co-chaired the ASHA Annual Research Symposium on Neural Regeneration in 2009, served as ASHA’s representative to the AAOHNS Guidelines on Improving Voice Outcomes after Thyroid Surgery and the American Academy of Neurology’s working group for the development of the Essential Tremor Quality Measurement Set, and served on ASHA’s working group for the development of the Core Instrumental Voice Assessment Protocol completed in 2015. She has published numerous book chapters, one workbook, and several publications in scientific and educational journals related to her clinical and research interests in the neural controls of the larynx for respiration, voicing, and swallowing functions. In 2011, she was awarded Fellow of the American Speech-Language-Hearing Association in recognition of her contributions to the profession.

  1. Acoustic Measures

    1. Acoustic Measures

    This chapter will introduce the goals of completing acoustic measures as a component of laryngeal function studies (CPT 92520). Completion of only acoustic measures can be coded to indicate partial completion of laryngeal function studies during a voice evaluation (CPT 92520-52).

  2. Aerodynamic Measures

    2. Aerodynamic Measures

    The purpose of this chapter is to introduce the goals of completing aerodynamic measures as a component of laryngeal function studies (CPT 92520). Completion of only aerodynamic measures can be coded to indicate partial completion of laryngeal function studies during a voice evaluation (CPT 92520-52).
