Although previous evidence has shown that deviated foot structure and function are associated with falls, little is known of the association between foot rotations and falls in apparently healthy older adults. Therefore, the main purpose of the study was to determine the associations between foot rotation and falls. In this cross-sectional study, we recruited 120 older women (mean±SD; age 71.01±6.77 years; height 158.92±21.41 cm; weight 70.29±12.97 kg; body-mass index 26.79±4.42 kg/m2). Foot rotations were assessed by using pressure platform (Zebris manufacturer, Munich, Germany), while the risk of falls was assessed by using Downtown Fall Risk Index questionnaire. Correlations and multiple regression models were applied to calculate the associations. In unadjusted model, higher foot rotation was associated with higher risk of falls (β = 0.14, p<0.001 for both feet). In a model adjusted for age, body-mass index, foot pain and fitness index, higher foot rotation remained associated with higher risk of falls (β = 0.10, p<0.001 for both feet). Our study shows that older adults with higher foot rotation are at higher risk of falls. Special interventions aiming to correct for deviated foot function in older women are warranted.
虽然先前的证据表明足部结构和功能的异常与跌倒有关，但对于足部旋转与健康老年人跌倒之间的关系知之甚少。因此，本研究的主要目的是确定足部旋转与跌倒之间的关系。在这项横断面研究中，我们招募了 120 名老年女性（平均±标准差；年龄 71.01±6.77 岁；身高 158.92±21.41cm；体重 70.29±12.97kg；身体质量指数 26.79±4.42kg/m2）。通过压力平台（Zebris 制造商，慕尼黑，德国）评估足部旋转，通过市区跌倒风险指数问卷评估跌倒风险。应用相关性和多元回归模型来计算关联。在未调整模型中，较高的足部旋转与较高的跌倒风险相关（双脚的β=0.14，p<0.001）。在调整年龄、身体质量指数、足部疼痛和健康指数的模型中，较高的足部旋转仍与较高的跌倒风险相关（双脚的β=0.10，p<0.001）。我们的研究表明，足部旋转较高的老年人跌倒风险更高。有必要针对老年女性足部功能异常进行特殊干预。
