言语和手势的产生都需要多个发音器官的精确协调。共济失调后构音障碍的特征已被充分记录，但对共济失调对手语的影响知之甚少，手语使用手和手臂作为发音器官。这是第一个研究共济失调性构音障碍的手语使用者。这项研究的新颖之处在于肢体被用于语言和非语言运动。值得注意的是，标志生产赤字大致类似共济失调性构音障碍，而非语言运动赤字类似于先前报道的共济失调性肢体运动。
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.
