The aim of this study was to compare the smiling behaviour of a group of Parkinson's disease sufferers with a control group of a similar age using a novel microcomputer-based approach, which utilises a mathematical model of the face to quantify facial expression. The findings indicate that the Parkinson's group differed from the control group in the frequency of smiling while watching a series of cartoons and in the degree of mouth opening during smiling. Both groups completed the Levine-Pilowsky Depression questionnaire, and patients with Parkinson's disease had significantly higher depression scores than those of the control group. Significant negative correlations between depression score and frequency of smiling, and depression score and inner eyebrow separation were also found.
本研究的目的是使用一种基于微型计算机的新颖方法，比较一组帕金森病患者与年龄相仿的对照组的微笑行为，该方法利用面部数学模型来量化面部表情。研究结果表明，帕金森病组在观看一系列卡通片时的微笑频率以及微笑时的张口程度与对照组不同。两组都完成了莱文-皮洛斯基抑郁问卷，帕金森病患者的抑郁得分显著高于对照组。还发现抑郁得分与微笑频率以及抑郁得分与眉内侧间距之间存在显著的负相关。
