An increasing amount of evidence shows that cognitive deficits and movement dysfunctions are not separated. Patients with mild cognitive impairment (MCI) can manifest fine motor disorders of the upper extremities. Handwriting is a complex and unique human activity involving both motor and cognitive coordination. Researchers from western countries have discovered that patients with MCI have abnormal handwriting features. However, no relevant studies have been conducted in the Chinese population. Owing to the cross-culture phenomenon of handwriting, the aim of this study is to find new handwriting tasks to demonstrate the differences in handwriting features between elderly patients with MCI and age-matched healthy individuals.
越来越多的证据表明，认知缺陷和运动功能障碍并非相互独立。轻度认知障碍（MCI）患者可能表现出上肢精细运动障碍。书写是一种复杂而独特的人类活动，涉及运动和认知协调。西方国家的研究人员发现，MCI 患者的书写特征存在异常。然而，在中国人群中尚未开展相关研究。由于书写存在跨文化现象，本研究旨在寻找新的书写任务，以展示 MCI 老年患者与年龄匹配的健康个体之间在书写特征上的差异。
