目的：这项横断面研究的目的是调查足弓畸形的影响，对身体特征，肌肉力量，和运动功能的老年妇女根据存在或不存在的pains.Methods：总体而言，145个社区居住的妇女，年龄在65至90岁，包括在这项研究中。我们测量了足弓高度比（AHR，背高/截断足长），并将AHR值高于、低于或在1.5标准差内的参与者分别分为高足弓组（HAG）、低足弓组（LAG）或正常足弓组（NAG）。我们还比较了（年龄、身高、体重、体重指数（BMI）和骨骼质量指数）、肌肉力量（握力和内在足部力量（IFS））和运动功能结果：运动检查和肌力仅在疼痛时三组间差异有统计学意义;在两步测试中，HAG、NAG和LAG值分别为0.98 cm/cm、1.19 cm/cm和1.18 cm/cm。在HAG、NAG和LAG中，IFS测量值分别为19.2N、24.2N和31.0N。结论：本研究表明，IFS降低影响老年女性高弓足的运动功能。虽然在疼痛评价方面没有显著差异，但HAG显示出最高的平均值，这被认为是导致两步值降低的原因。有研究表明，疼痛时的高足弓与IFS虚弱有关，并可能影响老年女性移动功能的下降。
Purpose:This cross-sectional study aimed to investigate the effects of foot arch deformities on physical characteristics, muscular strength, and motor function in older women depending on the presence or absence of pain.Methods:Overall, 145 community-dwelling women aged 65 to 90 years were included in this study. We measured the foot arch height ratio (AHR, dorsal height/truncated foot length) and classified participants with AHR values above, below, or within 1.5 standard deviations into the high-arched group (HAG), Low-Arched Group (LAG), or normal-arched group (NAG), respectively. We also compared body characteristics (age, height, weight, body mass index (BMI), and skeletal mass index), muscle strength (handgrip strength and intrinsic foot strength (IFS)), and locomotive function (two-step value and gait speed) among the three groups.Results:Locomotive examination and muscle strength showed significant differences among the three groups only in the presence of pain; in the two-step test, HAG, NAG, and LAG values were 0.98 cm/cm, 1.19 cm/cm, and 1.18 cm/cm, respectively. The IFS measured 19.2 N, 24.2 N, 31.0 N, respectively, in the HAG, NAG, and LAG.Conclusion:This study suggests that decreased IFS affects the mobility function of high-arched feet in older women. Although there was no significant difference in the evaluation of pain, HAG showed the highest average value, which is considered to contribute to the decreased two-step value. It has been suggested that a high-arched foot in the presence of pain is associated with IFS weakness and may affect the decline of mobility function in older women.
