Clinical measures of dysarthria in Friedreich Ataxia

Dysarthria in Friedreich Ataxia (FA) is difficult to quantify. This study evaluated a series of performance measures for speech in 22 patients with genetically confirmed FA and 16 age-matched controls. Tests included the PATA examination, the PATAKA examination, the Oral Motor component of the Boston Aphasia examination, the Boston Cookie Theft description task, and the Assessment of Intelligibility of Dysarthric Speech.
