Postural sway measured using force plate technology is a known risk factor for falls in older adults, but is currently underutilized due to the high cost and lack of portability issues associated with most force plate systems. The Balance Tracking System (BTrackS) is a new force plate that alleviates these barriers and has potential for widespread use. The present study provides important normative data for the BTrackS Balance Test of postural sway that improves its translational value to the field of gerontology.
BTrackS Balance Test postural sway results were accumulated from 6280 community-dwelling individuals across the adult lifespan. Data were assessed for effects of age, sex and body size. Stratified percentile rankings were then calculated.
BTrackS Balance Test results were dependent on age and sex, but not body size. Percentile rankings were, therefore, determined across various age groups for men and women separately, with no consideration of participant body size. A novel interaction was found between the age and sex factors, suggesting enhanced postural sway ability for women that becomes more pronounced with older age.
The results of the present study represent one of the largest sets of normative postural sway data ever published. These data translate directly into the field of gerontology as a tool for determining abnormalities in postural sway, which have been linked to various poor outcomes in older adults, such as high fall risk.

使用测力板技术测量的姿势摆动是老年人跌倒的已知危险因素，但由于大多数测力板系统成本高且便携性差，目前未得到充分利用。平衡跟踪系统（BTrackS）是一种新型测力板，它缓解了这些障碍，具有广泛应用的潜力。本研究为 BTrackS 平衡测试的姿势摆动提供了重要的规范数据，提高了其在老年学领域的转化价值。
从整个成年期的 6280 名社区居住者中积累了 BTrackS 平衡测试的姿势摆动结果。数据评估了年龄、性别和体型的影响。然后计算了分层百分位排名。
BTrackS 平衡测试结果取决于年龄和性别，但与体型无关。因此，分别为男性和女性在不同年龄组确定了百分位排名，而不考虑参与者的体型。发现年龄和性别因素之间存在一种新的相互作用，表明女性的姿势摆动能力增强，随着年龄的增长变得更加明显。
本研究的结果代表了有史以来发布的最大的规范姿势摆动数据之一。这些数据直接转化为老年学领域，作为确定姿势摆动异常的工具，姿势摆动异常与老年人的各种不良后果相关，例如高跌倒风险。老年医学与老年病学杂志 2018；18: 1225-1229。
