Motor speech patterns in Huntington disease.

Objective: Dysarthric speech of persons with Huntington disease (HD) is typically described as hyperkinetic; however, studies suggest that dysarthria can vary and resemble patterns in other neurologic conditions. To test the hypothesis that distinct motor speech subgroups can be identified within a larger cohort of patients with HD, we performed a cluster analysis on speech perceptual characteristics of patient audio recordings.

Methods: Audio recordings of 48 patients with mild to moderate dysarthria due to HD were presented to 6 trained raters.

A modified multimodal communication treatment for individuals with traumatic brain injury.

People living with the effects of traumatic brain injury (TBI) might use augmentative and alternative communication (AAC) due to cognitive-communication disabilities and/or co-occurring motor speech disorders. However, the most effective method for teaching people with TBI to use AAC strategies and resolve communication breakdowns is unknown. Prior research conducted with people with aphasia suggests an integrated multimodal treatment improved the use of AAC to resolve communication breakdowns.
