帕金森病患者说话时语调单调，音调和强度略有变化。本研究的目的是找出这些语言的变化是否可以解释主要是由运动障碍。即运动不能和发音器官的僵硬，或者情绪处理的改变是否起了额外的作用。对16例轻度PD患者和16例健康对照者（HQ）进行比较。基频（音高）和强度（响度）被确定为：（1）在非情绪语音中达到的最大上限和下限值（发声能力），（2）在要求的情绪语调（中性、悲伤、快乐）中说“安娜”时使用的上限和下限值（生产任务），或（3）模仿专业说话者时使用的上限和下限值（模仿任务）。虽然组没有显着差异，他们的发声能力，患者表现出显着较小的音高和强度范围比HC在生产任务。然而，在模仿任务中，范围再次相似。这些结果表明，情绪处理的改变有助于PD的言语变化，特别是关于情绪韵律，除了运动障碍。(C)2008年，《社会运动》创刊。
Patients with Parkinson's disease (PD) tend to speak monotonously with minor modulation of pitch and intensity. The goal of this study was to find out whether these speech changes can be explained mainly by motor impairment. i.e. akinesia and rigidity of the articulatory apparatus, or whether alterations of emotional processing play an additional role. Sixteen patients with mild PD and 16 healthy controls (HQ were compared. Fundamental frequencies (pitch) and intensities (loudness) were determined as (1) maximal upper and lower values achieved in nonemotional speech (phonation capacity), (2) upper and lower values used when speaking "Anna" in emotional intonation (neutral, sad, happy) as requested (production task), or (3) when imitating a professional speaker (imitation task). Although groups did not significantly differ in their phonation capacity, patients showed a significantly smaller pitch and intensity range than HC in the production task. In the imitation task, however, ranges were again similar. These results suggest that alterations of emotional processing contribute to speech changes in PD, especially regarding emotional prosody, in addition to motor impairment.
