Healthy and Pathological Gait GRAIL Dataset

This dataset contains biomechanical gait data collected from both healthy individuals and patients with pathological gait conditions. Data were acquired using the Gait Real-time Analysis Interactive Lab (GRAIL) system, which integrates an optical motion capture system with an instrumented split-belt treadmill. The dataset supports research on gait analysis, rehabilitation assessment, and clinical decision-making for elderly and pathological populations.本数据集收录了从健康个体与病理步态患者群体中采集的生物力学步态数据。数据采集依托步态实时分析交互实验室（Gait Real-time Analysis Interactive Lab，GRAIL）系统完成，该系统整合了光学运动捕捉系统与分体式测力跑台。本数据集可支撑针对老年群体及病理步态人群的步态分析、康复评估与临床决策相关研究。
