平衡不良和平衡障碍是福尔斯的主要预测因素。本研究的目的是确定基线定量静态躯干摇摆测量在预测287名社区居住的非痴呆老年美国人（平均年龄76.14 ± 6.82岁; 54%为女性）的意外福尔斯事件中的临床有效性。使用SwayStar™装置测量躯干摇摆，并将其量化为前后（俯仰）和内外（侧倾）平面中的角位移（以度为单位）。在一年的随访期内，66名老年人（23%）报告了福尔斯事件。在考克斯比例风险模型中，前后角位移是老年人发生福尔斯的强预测因子（校正年龄、性别、教育、RBANS总评分、医学合并症、老年抑郁量表评分、感觉障碍、步态速度和过去1年内跌倒史的风险比（aHR）= 1.59; p = 0.033），而内外平面的角位移不能预测福尔斯（aHR = 1.35; p = 0.276）。我们的研究结果揭示了定量躯干摇摆，特别是前后角位移，在预测老年人的事件福尔斯的意义。
Poor balance and balance impairments are major predictors of falls. The purpose of the current study was to determine the clinical validity of baseline quantitative static trunk sway measurements in predicting incident falls in a cohort of 287 community-dwelling non-demented older Americans (mean age 76.14 ± 6.82 years; 54% female). Trunk sway was measured using the SwayStar™ device, and quantified as angular displacement in degrees in anterior-posterior (pitch) and medio-lateral (roll) planes. Over a one-year follow-up period, 66 elders (23%) reported incident falls. Anterior-posterior angular displacement was a strong predictor of incident falls in older adults in Cox proportional hazards models (hazard ratio adjusted for age, gender, education, RBANS total score, medical comorbidities, geriatric depression scale score, sensory impairments, gait speed, and history of fall in the past 1 year ((aHR) = 1.59; p = 0.033) whereas, angular displacement in the medio-lateral plane was not predictive of falls (aHR = 1.35; p = 0.276). Our results reveal the significance of quantitative trunk sway, specifically anterior-posterior angular displacement, in predicting incident falls in older adults.
