Gaits constitute the most fundamental and common form of human locomotion and are essential in daily activities. We aimed to investigate gait parameters in medically and cognitively healthy older adults to determine the independent effects of age, physical attributes, and cognition on these parameters.
This retrospective study enrolled healthy older adult participants aged 50 years or older with normal cognition and no neurological symptoms or medical/surgical history that could affect gait. Quantitative gait analysis was conducted via the GAITRite Electronic Walkway, which categorizes gait parameters into spatiotemporal, spatial, temporal, phase, and variability. Gait parameters were compared between sexes across different age groups. The independent effects of age, Mini-Mental State Examination score, and physical characteristics were analyzed via a multiple regression model.
This study included 184 participants with an average age of 72.2 years. After adjusting for age, height, and footwear, only the base width and its variability differed between the sexes. Gait parameters varied significantly among different age groups, revealing multiple interparameter associations. Age was independently correlated with decreased velocity, step and stride lengths, single support time percentage and increased double support time, double support time percentage, and variability parameters, excluding the coefficient of variance of base width. Height was positively correlated with velocity, step and stride lengths, and base width, whereas leg length was negatively associated with cadence and positively associated with temporal parameters of gait.
Gait parameters in healthy older adults were not only associated with age and physical characteristics but also had interparameter correlations.
步态是人类最基本、最常见的运动形式，在日常活动中至关重要。我们旨在研究医学和认知功能均健康的老年人的步态参数，以确定年龄、身体属性和认知对这些参数的独立影响。
这项回顾性研究纳入了50岁及以上的健康老年参与者，他们认知正常，没有可能影响步态的神经症状或内科/外科病史。通过GAITRite电子步道进行定量步态分析，该分析将步态参数分为时空参数、空间参数、时间参数、相位参数和变异性参数。比较了不同年龄组中不同性别的步态参数。通过多元回归模型分析年龄、简易精神状态检查表得分和身体特征的独立影响。
本研究纳入了184名参与者，平均年龄为72.2岁。在对年龄、身高和鞋类进行校正后，仅基础宽度及其变异性在性别之间存在差异。步态参数在不同年龄组之间有显著差异，揭示了多个参数间的关联。年龄与速度降低、步长和步幅缩短、单支撑时间百分比增加以及双支撑时间、双支撑时间百分比和变异性参数增加独立相关，但基础宽度的变异系数除外。身高与速度、步长和步幅以及基础宽度呈正相关，而腿长与步频呈负相关，与步态的时间参数呈正相关。
健康老年人的步态参数不仅与年龄和身体特征有关，而且参数之间存在相关性。
