Abstract	Speech and sign production both require precise coordination of multiple articulators. The characteristics of dysarthria following ataxia have been well-documented, but less is known about the consequences of ataxia for sign language, which uses the hands and arms as articulators. This is the first study to examine ataxic dysarthria in a sign language user. What is novel in this research is that the limbs are employed for both linguistic and non-linguistic movements. Notably, sign production deficits broadly resembled ataxic dysarthria, while non-linguistic movement deficits were similar to those previously reported for ataxic limb movement.
