Yorkston, K.M. (1996). Treatment efficacy: Dysarthria. Journal of Speech and Hearing Research, 39(5),S46-S57. Type of Study Treatment efficacy Subjects Many studies with a variety of subjects Diagnoses TBI Parkinson's disease Stroke Amyotrophic lateral sclerosis Cerebral palsy Speech Condition Dysarthria, range of severity Purpose To establish treatment efficacy standards based on studies of speech treatment with various populations. Methods Analysis of group and single-subject experimental designs and case studies. Results Physiological approaches, feedback of acoustic information, rate control, and breath patterning have been used in treating people with TBI. Long-term follow-up is needed because people with TBI change over time. Alphabet boards and palatal lifts are useful in TBI. Outcomes are measured by muscle strength, muscle control, reduction in specific deviant features, and changes in overall features including intelligibility,., speaking rate, and naturalness. Treatment Implications All of the above approaches should be considered in treating TBI patients.   Assessment Treatment Speech Characteristics Books and Book Chapters Instruments Other Links Search Home   To return to the Abstract References, click on Assessment , Treatment  , or Speech Characteristics or use your browser to go Back.
