The main purpose of the study was to establish a gait speed cut-off value to predict foot pain and the risk of falls among community-dwelling older adults.
In this cross-sectional study, one-hundred and twenty White older women speaking Croatian (mean ± SD age 71.02 ± 6.78 years, height 161.77 ± 6.23 cm, weight 70.29 ± 12.97 kg, body mass index 26.79 ± 4.42 kg/m) were recruited. The prevalence of foot pain was assessed by a single-item question and the risk of falls by the Downtown Fall Risk Index with a proposed cut-off value of "low risk" (<3 points) vs "high risk" (≥3 points) of falls. Self-selected gait speed (the independent variable) was estimated with a pressure platform (Zebris Company, Munich, Germany).
Mean gait speed was 0.95 m/s. Of the total sample, 53.30% and 33.30% reported foot pain and had higher risk of falls. For foot pain and the risk of falls, gait speed cut-off values were 0.88 m/s and 0.85 m/s (area under the curve = 0.80 and 0.83, standard error = 0.043 and 0.043, < 0.001). Sensitivity for foot pain and the risk of falls was 66.20% and 85.90% and specificity was 84.80% and 69.00%. Slower gait speed was associated with higher prevalence of foot pain (OR = 10.92, 95% CI 4.28 to 27.89, < 0.001) and higher risk of falls (OR = 13.59, 95% CI 5.45 to 33.87, < 0.001).
Proposed gait speed values of 0.88 m/s and 0.85 m/s may be used in clinical settings to predict foot pain and the risk of falls among community-dwelling older women.
本研究的主要目的是建立一个步速临界值,以预测社区居住的老年人的足部疼痛和跌倒风险。
在这项横断面研究中,招募了 120 名讲克罗地亚语的白种老年女性(平均年龄 71.02 ± 6.78 岁,身高 161.77 ± 6.23cm,体重 70.29 ± 12.97kg,体重指数 26.79 ± 4.42kg/m)。通过单一问题评估足部疼痛的患病率,通过“Downtown Fall Risk Index”评估跌倒风险,建议“低风险”(<3 分)与“高风险”(≥3 分)的跌倒风险。使用压力平台(德国慕尼黑 Zebris 公司)评估自我选择的步速(自变量)。
平均步速为 0.95m/s。在总样本中,53.30%和 33.30%报告有足部疼痛和更高的跌倒风险。对于足部疼痛和跌倒风险,步速临界值分别为 0.88m/s 和 0.85m/s(曲线下面积分别为 0.80 和 0.83,标准误差分别为 0.043 和 0.043,<0.001)。足部疼痛和跌倒风险的敏感性分别为 66.20%和 85.90%,特异性分别为 84.80%和 69.00%。较慢的步速与更高的足部疼痛患病率(OR=10.92,95%CI 4.28 至 27.89,<0.001)和更高的跌倒风险(OR=13.59,95%CI 5.45 至 33.87,<0.001)相关。
建议将 0.88m/s 和 0.85m/s 的步速值用于临床,以预测社区居住的老年女性的足部疼痛和跌倒风险。
