Association Between Gait Assessed by Intelligent System and Cognitive Function in Silent Cerebrovascular Disease

This study is a multi-center prospective cohort study. We will continuously recruit subjects with silent cerebrovascular disease aged 60 to 85 years from Shanghai and Guizhou. Data including demographic characteristics, medical history, other concomitant diseases, neurological function assessments, laboratory examinations, imaging examinations, and other clinical data and health economics survey responses will be collected from all subjects. At baseline, all subjects will undergo gait assessment using the intelligent system and cognitive function scale assessment by clinicians. According to the intelligent gait results, the subjects will be divided into normal and abnormal gait groups. All subjects will be observed naturally for 1 year, and all medical behaviors will be recorded. All subjects will be interviewed by telephone for the occurrence of vascular events and changes in medical behaviors at half a year after enrollment and followed up at 1 year after enrollment, including gait evaluation using the intelligent system and cognitive function scale evaluation by clinicians. During the follow-up period, patients can visit the hospital for follow-up at any time when their condition changes.
