Early Speech Deterioration In Amyotrophic Lateral Sclerosis: A Case Study Of Newscaster Donna Britt, Emily Watkins

LSU Master's Theses

Abstract

Purpose: The aim of this study is to detect and track speech changes using acoustic and perceptual measures in an individual (a local newscaster) with amyotrophic lateral sclerosis (ALS) using data from before her diagnosis, around the time of her diagnosis, and after her diagnosis.

Methods: Six time points, ranging from 37 months around her diagnosis, were analyzed from one speaker with ALS. Three acoustic parameters were measured: articulation rate, acoustic vowel space, and the slope of the second formant. Additionally, two experts with more than 10 years of experience perceptually analyzed the speech samples on 17 characteristics using …

Evaluating The Relationship Between Diadochokinesis And Severity Of Dysphagia As It Relates To Forced Vital Capacity In Individuals With Amyotrophic Lateral Sclerosis, Arthur Franklin Knack

Wayne State University Dissertations

Purpose: To determine if the severity of dysphagia, as determine by Penetration Aspiration Scale (PAS) ratings and pharyngeal residue scale ratings in individuals with ALS, can be predicted through performance on diadochokinesis (DDK) and force vital capacity (FVC) measures.

This study was designed to evaluate differences in performance of clinical measures and objective swallowing severity ratings between individuals with ALS and a Control group of similar age. The goal of this study was to attempt to develop a clinical assessment battery that can predict swallowing impairment in ALS patients. In addition, potential predictive relationships between dysphagia ratings and other commonly …
