The purpose of this research was to describe the variability of forward head posture in healthy older women, and to investigate the influence of age on variability.
This cross-sectional descriptive study included 187 healthy community-dwelling women volunteers ranging in age from 65-96 years. The forward head posture (FHP) measurement was derived from a sagittal photograph. The subjects were asked to perform a series of standing activities, and the photograph was taken while the subjects were performing these activities. Data analysis included descriptive analysis, FHP measurement analysis for normalcy, one-factor ANOVA with FHP by age group, post-hoc Tukey analysis, and trend analysis for the age-FHP relationship.
Three age-group normative FHP means were identified: 48.84 degrees (SE 0.97) for the 65-74 year old group, 41.20 degrees (SE 0.78) for the 75-84 year old group, and 35.60 degrees (SE 1.76) for the 85+ year group. Significant differences were found in the FHP between these age groups. A subsequent trend analysis demonstrated a linear relationship between age and the FHP, with older women demonstrating a more severe FHP.
Age-associated variability in the FHP of healthy elderly women has been identified. The FHP values determined by this research may serve as normative guidelines for clinicians when conducting postural assessments, and in clinical decision-making regarding possible interventions.
本研究旨在描述健康老年女性头部前倾姿势的变异性，并探讨年龄对变异性的影响。
这项横断面描述性研究纳入了187名年龄在65至96岁之间、居住在社区的健康女性志愿者。头部前倾姿势（FHP）测量值来自矢状面照片。受试者被要求进行一系列站立活动，并在其进行这些活动时拍摄照片。数据分析包括描述性分析、FHP正常性测量分析、按年龄组对FHP进行单因素方差分析、事后Tukey分析以及年龄与FHP关系的趋势分析。
确定了三个年龄组的FHP标准均值：65至74岁组为48.84度（标准误0.97），75至84岁组为41.20度（标准误0.78），85岁及以上组为35.60度（标准误1.76）。这些年龄组之间的FHP存在显著差异。随后的趋势分析表明年龄与FHP之间存在线性关系，老年女性的FHP更为严重。
已确定健康老年女性FHP中与年龄相关的变异性。本研究确定的FHP值可为临床医生进行姿势评估以及在关于可能干预措施的临床决策时提供标准指导。
