The present study examined tongue strength and speech characteristics in six individuals with Parkinson disease across two sessions of approximately 20 months. The Iowa Oral Performance Instrument was used to measure tongue strength. In addition, speech samples were recorded and rated for respiration, articulation, resonance, and phonation by five speech-language pathologists experienced in the assessment and treatment of dysarthria. A Wilcoxon signed ranks test was used to compare tongue strength measures across the sessions. Wilcoxon signed ranks tests were also conducted to compare the judges' perceptual ratings over time. Results revealed a significant reduction in tongue strength at the second session. Perceptions of speech characteristics specifically, consonant imprecision, vowel imprecision, rate, and overall speech also demonstrated a consistent pattern of degradation over time, though those changes were not statistically significant. / A Thesis submitted to the Department of Communication Disorders in partial
