Intensive Dysarthria Sessions in Adults and Children With Down Syndrome

This research study is designed to investigate the feasibility and treatment effects of a
behavioral speech treatment in adults and children with Down Syndrome (DS) and dysarthria.
The speech sessions will provide an intensive, articulation-based intervention focused on
increasing effort during speech production via use of "clear speech." A single subject
multiple baselines across subjects design will be employed in a total of six subjects
divided into two groups of three. Changes in dependent measures will be determined by visual
inspection, effect size determination, and time series analysis. The study follows accepted
procedures in rehabilitation treatment and research and there are minimal foreseeable risks
associated with participation.
