在四组男性受试者中研究了韵律障碍：肌萎缩性侧索硬化症（ALS）和轻度可懂性障碍受试者，ALS和更严重的可懂性丧失受试者，小脑疾病受试者和神经学正常对照组。韵律障碍的评估与感知评级和声学措施有关的持续时间，f（0），和强度内的音调单位的会话样本的调节。可懂度降低和韵律障碍不一定在所有科目同样受损，它的结论是，这些是构音障碍的严重程度的补充指标。与神经系统正常的对照组相比，临床组倾向于减少音调单位的总持续时间，在音调单位中产生更少的单词，并且使用更小的f（0）变化。并对构音障碍的韵律评估提出了建议。
Dysprosody was studied in four groups of male subjects: subjects with amyotrophic lateral sclerosis (ALS) and mild intelligibility impairment, subjects with ALS and a more severe intelligibility loss, subjects with cerebellar disease, and neurologically normal controls. Dysprosody was assessed with perceptual ratings and acoustic measures pertaining to the regulation of duration, f(0), and intensity within tone units of conversational samples. Intelligibility reduction and prosodic disturbance were not necessarily equally impaired in all subjects, and it is concluded that these are complementary indices of severity of dysarthria. Compared to the neurologically normal control group, the clinical groups tended to decrease the overall duration of tone units, produce fewer words in a tone unit, and use smaller variations in f(0). Recommendations are offered for the assessement of prosody in dysarthria.
