概括

在不同环境下进行的步行分析显示,行走速度和步伐长度因发作持续时间而异,但关节运动保持一致. 标准化实验室外数据收集对于准确的比较至关重要.

科学领域:

生物力学生物力学
步态分析步态分析
可穿戴式传感器穿戴式传感器

背景情况:

步行动力学在不同环境和人群中存在差异,包括那些患有膝关节关节炎的人.
与受控实验室设置相比,实验室外行走数据具有不同的特征.
步行时间对步态分析和实验室外数据的标准化细分的影响尚不清楚.

研究的目的:

根据步行时间和环境,调查步行动力学上的差异.
为了比较年轻人,老年人和膝关节骨关节炎的老年人的步态.
确定设置或发作持续时间是否会影响不同年龄和健康群体的步态参数.

主要方法:

十个年轻人,十个老年人和十个患有膝关节关节炎的老年人参与了这项研究.
在实验室内进行的步态分析之后,在实验室外使用四个IMU (惯性测量单位) 进行了行走.
走路速度,脚步长度和关节运动范围 (ROM) 计算了长 (>60秒) 和短 (≤60秒) 的实验室外和实验室内条件.

主要成果:

步行速度和步伐长度受到设置和发作持续时间的显著影响,在实验室内更大.
在关节,膝关节或脚关节的运动范围 (ROM) 之间没有发现任何显著的差异.
