Understanding the factors and mechanisms that determine balance in seniors appears vital in terms of their self-reliance and overall safety. The study aimed to determine the relationship between the features of feet structure and the indicators of postural stability in the elderly.
The study group comprised 80 seniors (41F, 39M; aged 75-85 years). CQ-ST podoscope and the CQ-Stab 2P two-platform posturograph were used as primary research tools. The data were analyzed based on Spearman's rank correlation and forward stepwise regression.
Analysis of forward stepwise regression identified the left foot length in females and Clarke's angle of the left foot in men as significant and independent predictors of postural up to 30% of the variance of dependent variables.
Longer feet provide older women with better stability, whereas in men, the lowering of the longitudinal arch results in postural deterioration. In the elderly, the left lower limb shows greater activity in the stabilizing processes in the standing position than the right one. In gerontological rehabilitation special attention should be paid to the individually tailored, gender-specific treatment, with a view to enhancing overall safety and quality of seniors' lives.
就老年人的自立能力和整体安全而言，了解决定其平衡能力的因素和机制显得至关重要。本研究旨在确定足部结构特征与老年人姿势稳定性指标之间的关系。
研究组由80名老年人组成（41名女性，39名男性；年龄在75 - 85岁之间）。主要研究工具为CQ - ST足型仪和CQ - Stab 2P双平台姿势描记仪。数据采用Spearman等级相关性分析和向前逐步回归分析。
向前逐步回归分析确定，女性的左脚长度和男性的左脚克拉克角是姿势的显著且独立预测因素，可解释高达30%的因变量方差。
脚较长能为老年女性提供更好的稳定性，而对男性来说，足纵弓降低会导致姿势稳定性变差。在老年人中，站立时左下肢在稳定过程中的活动比右下肢更活跃。在老年康复中，应特别关注针对个体和性别的个性化治疗，以提高老年人的整体安全性和生活质量。
