Communication Sciences and Disorders 615
COSD 615. Voice and Resonance Disorders
Prerequisites: Graduate standing and COSD 316 – Hearing Science or permission of the Instructor
Credit Hours: (3)
Advanced study of voice science including motor control, phonation, respiration, resonance, perception, laryngeal anatomy-physiology, and current methods for prevention, assessment, and intervention of voice disorders in children and adults.
Detailed Description of the Content of the Course
The major content of the course will be as follows:
· Laryngeal anatomy, histology and physiology
· Kinematics of phonation
· Theories of speech motor control and phonation
· Ventilatory dynamics
· Psychosocial aspects of voice production
· Sensory physiology
· Voice and speech perception
· Applied voice science
· Pediatric voice disorders: infant cry to puberty
· Adolescent voice disorders: post-puberty to adulthood
· Adult and geriatric voice disorders: adulthood-to-geriatrics
· Assessment of voice disorders
· Surgical interventions
· Current treatment plans and clinical implications
· Cultural and lifespan issues of voice disorders
· Special considerations for care of professional voice
Detailed Description of Conduct of Course
The course may be presented primarily from a lecture format and may consist of weekly demonstrations. Students may also conduct individual and group projects designed to reinforce theory and application. Audiovisual materials (e.g. videotapes & historical films) may be used regularly. Case studies may be used to demonstrate how current methodologies can be applied to clinically diverse populations.
Goals and Objectives of the Course
By the conclusion of the course students will be able to identify and discuss the major theoretical and clinical aspects of voice science, voice and resonance disorders, current instrumentation used to study voice/speech production and perception, and apply these to diagnostic and therapeutic management strategies for all ages.
Students will be assessed on a regular basis and with immediate knowledge of results. Weekly reviews and brief quizzes may be used to monitor progress. Three major tests may be scheduled during the term. Student projects and case studies may be presented during the last two weeks of class.
In accordance with new professional accreditation standards (American Speech Language-Hearing Association, 2003), student performance will be monitored and tracked as part of the department’s Formative Assessment Plan and Compliance Standards. More specifically, student learning will be monitored for each of the content areas listed above (Section 2.a). In-class discussions may identify areas for concentrated instruction. Review/study sessions, and individual and group monitoring may be used to reinforce concepts. The number and frequency of these may be correlated with test performance to assess success and facilitation of learning.
Other Course Information
The course will emphasize the related nature of voice production and disorders to other courses within the curriculum. Cultural, sociolinguistic, neurological and behavioral aspects of communication will be presented in an integrative manner. Ongoing assessment (e.g. periodic and anonymous surveys and peer review) will be used to enhance instruction.
