Vocal Function Exercises For Normal Voice: The Effects Of Varying Dosage, Maria H. Bane

Theses and Dissertations--Communication Sciences and Disorders

The primary purpose of this investigation was to explore the effects of variable doses of home practice Vocal Function Exercises (VFEs) on attainment of pre-established maximum phonation time (MPT) goals in individuals between the ages of 18 and 25 with normal voice. A secondary purpose was to monitor for potentially toxic effects of high doses of VFEs. Three experimental groups completed a six-week VFE protocol and practiced twice daily. The low dose group performed each exercise once, the traditional group twice, and the high dose group four times. Results indicated significant change in VFE MPT for all three groups and …

The Use Of Gesture In Self-Initiated Self-Repair Sequences By Persons With Non-Fluent Aphasia, Eleanor M. Feltner

Theses and Dissertations--Linguistics

This study examines the relationship between types of gestures and instances of self-initiated self-repair (SISR) used by persons with non-fluent aphasia (NFA), which is a type of aphasia characterized by stilted speech or signing (Papathanasiou et al., 2013), in interactions with clinicians. Conversation repairs in this study are assessed using the framework of Conversation Analysis (CA), which is an approach for describing, analyzing, and understanding social interaction (Sidnell, 2010). Previous linguistic studies have demonstrated a distinct preference for the use of gesture during a repair by persons with aphasia (Goodwin, 1995; Klippi, 2015; Wilkinson, 2013). This study draws more conclusive …

Investigating The Efficacy Of Vocal Function Exercises In Improving Vocal Function In Adults Irradiated For Laryngeal Cancers: A Three Part Dissertation, Vrushali Angadi

Theses and Dissertations--Rehabilitation Sciences

Deterioration in voice quality following radiation therapy for the treatment of laryngeal cancers (LC) is well documented in literature. The majority of studies show that these voice problems are long term and in some cases permanent. Deterioration in voice quality, especially over a period of time could lead to significant communication difficulties in daily life or in some cases could even result in loss of profession. Despite the negative effects of radiation therapy on voice quality being well documented, few studies have focused on the efficacy of voice therapy in the irradiated LC population.

The purpose of this study was …

Vocalization Subsystem Responses To A Temporarily Induced Unilateral Vocal Fold Paralysis, Daniel J. Croake

Theses and Dissertations--Rehabilitation Sciences

Healthy voicing is thought to be dependent on a dynamic balance of three interactive subsystems: respiration, phonation, and resonance. Theoretically, multiple patterns of subsystem interactions likely underlie healthy voice production; however surprisingly little quantitative data exists defining the nature of these subsystem production patterns and interactions across individuals.

The central aim of this study was to quantify the interactions of the vocalization subsystems in a non-perturbed and perturbed condition (induced unilateral vocal fold paralysis) in 10 vocally healthy participants. Respiratory inductance plethysmography, laryngeal aerodynamics, and acoustic formant data were used to measure the proportional contributions of, and changes to, the …
