Abstract

The purpose of this single subject research study was to prove the efficacy of SPEAK OUT! therapy in improving loudness, rate of speech, and quality of life for individuals who have hypokinetic dysarthria due to Parkinson’s Disease. In this A-B-A design, five weeks of SPEAK OUT! therapy was provided twice a week to four individuals with a diagnosis of Parkinson’s disease. Results showed an increase in loudness in conversation and improved quality of life measured by statistical and visual analysis. These findings contribute to the research behind the use of SPEAK OUT! therapy for individuals with HKD due to PD.
