Reduced spontaneous blinking is a recognized Parkinson's disease (PD) feature. In contrast, voluntary blinking has been less studied and might serve as a measurable marker of facial bradykinesia. We tested 31 PD patients and 31 controls. Participants were filmed during conversation and a rapid blinking task. Both tasks were videorecorded to count the number of blinks per second. PD patients had lower blink rates. Rapid blinking accurately discriminated between groups with 77% sensitivity and 71% specificity. To conclude, rapid blinking may be a simple and quantifiable task of facial bradykinesia.
眨眼减少是公认的帕金森病（PD）特征。相比之下，自愿眨眼的研究较少，它可能是面部运动迟缓的可测量标志物。我们测试了 31 名 PD 患者和 31 名对照者。参与者在交谈和快速眨眼任务中被拍摄。两个任务都被录像，以计算每秒眨眼次数。PD 患者的眨眼频率较低。快速眨眼能以 77%的灵敏度和 71%的特异性准确区分两组。总之，快速眨眼可能是一种简单且可量化的面部运动迟缓的任务。
