: Forward flexed posture is an impairment in body structure commonly seen among older adults and those with pathologies such as ankylosing spondylitis and osteoporosis. Accurate measurement of forward flexed posture is important as it is related to pain, mobility limitations, and falls. Our purpose was to examine the reliability and determinants of forward flexed posture as indicated by tragus-to-wall (TTW) distance: Twenty healthy younger and 20 healthy older adults were included in this secondary analysis of data from a neck strength study. Measurements included the linear distance of TTW standing naturally and with neck retraction, age, gender, body mass index (BMI), and neck retraction strength. Measurements were performed initially by 2 investigators and by the primary investigator 1 week later. Intraclass correlation coefficients (ICCs) (model 3,1) described relative reliability and Bland-Altman plots characterized absolute reliability. A mixed general linear model examined the determinants for TTW distance: Good inter-rater (ICC = 0.811-0.878) and test-retest reliability (ICC = 0.853-0.862) were found in both positions. Bland-Altman plots showed that absolute limits of agreement ranged from - 1.9 to +3.8 cm for inter-rater reliability and -2.4 to +2.6 cm for test-retest reliability. Analysis of TTW determinants demonstrated significant differences between neck positions, dichotomous age groups, and BMI groups (p ≤ 0.001). There was no significant difference based on neck strength.: Our results indicate that TTW distance, measured using a standardized procedure, is a reliable method of quantifying forward flexed posture. TTW distance is greater in relaxed standing, older individuals, and those with greater BMI.
前屈姿势是一种常见于老年人以及患有强直性脊柱炎和骨质疏松症等病症人群的身体结构损伤。准确测量前屈姿势很重要，因为它与疼痛、活动受限和跌倒有关。我们的目的是研究用耳屏到墙（TTW）距离表示的前屈姿势的可靠性和决定因素：20名健康年轻人和20名健康老年人被纳入这项颈部力量研究数据的二次分析。测量包括自然站立和颈部后缩时的TTW线性距离、年龄、性别、体重指数（BMI）和颈部后缩力量。测量最初由2名研究人员进行，1周后由主要研究人员进行。组内相关系数（ICC）（模型3,1）描述相对可靠性，布兰德-奥特曼图表征绝对可靠性。一个混合通用线性模型研究了TTW距离的决定因素：在两个姿势中均发现了良好的评分者间（ICC = 0.811 - 0.878）和重测可靠性（ICC = 0.853 - 0.862）。布兰德-奥特曼图显示，评分者间可靠性的一致性绝对限度为-1.9至+3.8厘米，重测可靠性为-2.4至+2.6厘米。TTW决定因素分析表明，颈部姿势、二分年龄组和BMI组之间存在显著差异（p≤0.001）。基于颈部力量没有显著差异。我们的结果表明，使用标准化程序测量的TTW距离是量化前屈姿势的可靠方法。放松站立时、年龄较大者以及BMI较高者的TTW距离更大。
