我们调查了19名帕金森病患者（PD; 14名男性和5名女性）和26名健康对照（13名男性和13名女性）的面部表情。参与者参与了旨在唤起情感面部表情的实验情境，包括观看视频片段和进行对话，并被要求摆出情感姿势和模仿非情感面部动作。表达性的测量与主观评定量表，客观的面部测量（面部动作编码系统），和自我报告问卷。正如预期的那样，PD参与者在实验情况下表现出自发的面部表情减少。PD参与者也比控制组更难做出情绪表情和模仿非情绪面部运动。然而，尽管存在这些困难，PD参与者的整体表现力水平仍然与情感体验和社会背景有关。
We investigated facial expressivity in 19 people with Parkinson's disease (PD; 14 men and 5 women) and 26 healthy controls (13 men and 13 women). Participants engaged in experimental situations that were designed to evoke emotional facial expressions, including watching video clips and holding conversations, and were asked to pose emotions and imitate nonemotional facial movements. Expressivity was measured with subjective rating scales, objective facial measurements (Facial Action Coding System), and self-report questionnaires. As expected, PD participants showed reduced spontaneous facial expressivity across experimental situations. PD participants also had more difficulty than controls posing emotional expressions and imitating nonemotional facial movements. Despite these difficulties, however, PD participants' overall level of expressivity was still tied to emotional experience and social context.
