客观的。根据平均首选脚部放置位置建立平衡测试的标准化站立位置，并将其与现有标准进行比较。设计。横断面研究。背景。事实证明，脚的方向会对平衡测试期间获得的结果产生显着影响，因此需要标准化的脚定位。不幸的是，目前的建议似乎并没有解决“不舒服”或“不自然”的足部位置对稳定反应控制的潜在影响的担忧。方法。本研究通过对年龄从 19 岁到 97 岁的 262 名受试者（89 名男性，173 名女性）的足部轨迹进行测量，确定了首选站立宽度和足部角度的集中趋势和方差。结果。结果显示，尽管由于性别或年龄（小于或等于 50 与 > 60）造成的平均差异很小，但不同受试者的首选站立宽度和角度存在很大程度的差异。平均首选脚部位置是脚跟中心之间的距离为 0.17 m，脚长轴之间的角度为 14 度。现有的站立位置标准远远超出了首选脚部放置的范围。结论。各种首选的脚放置位置清楚地强调了平衡测试过程中标准化的必要性。与现有标准相比，基于平均偏好的标准将减少“不舒服”或“不自然”脚部位置的潜在影响。
Objective. To establish a standardized stance position for balance testing based on average preferred foot placement, and to compare this to existing standards.Design. Cross-sectional study.Background. It has been shown that the orientation of the feet can have a marked influence on the results obtained during balance testing, prompting the need for standardized foot positioning. Unfortunately, current recommendations do not appear to address concerns a bout the potential effects of 'uncomfortable' or 'unnatural' foot positions on the control of stabilizing reactions.Methods. The present study identifies the central tendency and variance of the preferred stance width and foot angle, measured from foot tracings in 262 subjects (89 male, 173 female) ranging in age from 19 to 97 years.Results. Results revealed a great degree of variability in preferred stance width and angle across subjects, although mean differences due to gender or age (less than or equal to 50 versus > 60) were small. The average preferred foot position was 0.17 m between heel centres, with an angle of 14 degrees between the long axes of the feet. Existing standards for stance position lie well outside the range of preferred foot placement.Conclusions. The wide range of preferred foot placements clearly highlights the need for standardization during balance testing. A standard based on average preference would reduce potential effects of 'uncomfortable' or 'unnatural' foot positions, in comparison to existing standards.
