In 1885, while working at the University of Pennsylvania, Eadweard Muybridge and Francis Dercum used nascent photographic technology to perform the first-ever motion picture study of neurologic patients. To date, our clinical understanding of the Muybridge-Dercum project has been limited to those clinical details included in a handful of contemporaneous publications by Dercum et al. In this study, recently rediscovered clinical notebooks from the Hospital of the University of Pennsylvania's Dispensary for Nervous Diseases were reviewed and found to contain the original clinical records of 9 of Muybridge and Dercum's photographic subjects. These records add new clinical insights into our understanding of this historic photographic study and revive the zeitgeist of a foundational period in the development of neurology as a medical subspecialty in the United States.

1885 年，在宾夕法尼亚大学工作期间，Eadweard Muybridge 和 Francis Dercum 使用新兴的摄影技术对神经系统患者进行了首次电影研究。迄今为止，我们对 Muybridge-Dercum 项目的临床理解仅限于 Dercum 等人在少数同时期出版物中包含的那些临床细节。在这项研究中，对宾夕法尼亚大学医院神经疾病药房最近重新发现的临床笔记本进行了审查，发现其中包含 9 个 Muybridge 和 Dercum 摄影对象的原始临床记录。
