Gait analysis is crucial for the detection and management of various neurological and musculoskeletal disorders. The identification of gait events is valuable for enhancing gait analysis, developing accurate monitoring systems, and evaluating treatments for pathological gait. The aim of this work is to introduce the Smart-Insole Dataset to be used for the development and evaluation of computational methods focusing on gait analysis. Towards this objective, temporal and spatial characteristics of gait have been estimated as the first insight of pathology. The Smart-Insole dataset includes data derived from pressure sensor insoles, while 29 participants (healthy adults, elderly, Parkinson's disease patients) performed two different sets of tests: The Walk Straight and Turn test, and a modified version of the Timed Up and Go test. A neurologist specialized in movement disorders evaluated the performance of the participants by rating four items of the MDS-Unified Parkinson's Disease Rating Scale. The annotation of the dataset was performed by a team of experienced computer scientists, manually and using a gait event detection algorithm. The results evidence the discrimination between the different groups, and the verification of established assumptions regarding gait characteristics of the elderly and patients suffering from Parkinson's disease.
步态分析对于检测和管理各种神经和肌肉骨骼疾病至关重要。步态事件的识别对于增强步态分析、开发准确的监测系统以及评估病理性步态的治疗方法非常有价值。本工作旨在引入 Smart-Insole 数据集,用于开发和评估专注于步态分析的计算方法。为此,估计了步态的时间和空间特征,作为病理的初步见解。Smart-Insole 数据集包括来自压力传感器鞋垫的数据,而 29 名参与者(健康成年人、老年人、帕金森病患者)进行了两组不同的测试:直走和转弯测试,以及改良的计时起身和走动测试。一位专门研究运动障碍的神经病学家通过对 MDS-统一帕金森病评定量表的四项进行评分来评估参与者的表现。数据集的注释是由一支经验丰富的计算机科学家团队手动完成的,并使用步态事件检测算法完成。结果证明了不同组之间的区分,以及对老年人和帕金森病患者步态特征的既定假设的验证。
