客观的平衡和步态测量有可能改善对未来跌倒者的预测，因为平衡和步态障碍是常见的前兆。我们使用了配备可穿戴惯性传感器的仪表式站立和行走测试(ISAW)，以最大限度地提高在短测试中评估的平衡和步态范围。我们假设，ISAW对各种步态和平衡域的客观测量将改善跌倒预测，超越跌倒历史，并优于步态速度或步态速度双重任务成本。我们招募了214名高功能老年男性(平均82岁)，其中91名参与者(42.5%)在ISAW测试后的12个月内有一次或多次摔倒。国际田联的测试包括S 30米的站姿，然后是7米走、转身和回程。我们使用17个ISAW指标检验了跌倒的回归模型，包括年龄和跌倒病史，并根据AUC和包括的指标对表现最好的模型进行了表征。与年龄和跌倒病史相比，ISAW测试改善了对未来跌倒和不跌倒的区分(AUC从0.69提高到0.75)。具有1个ISAW测量的模型通常包括姿势摇摆测量，具有2个ISAW测量的模型包括转身测量，具有3个ISAW测量的模型包括步态可变性测量，具有4或5个测量的模型添加步态起始测量。在这个高功能队列中，步态速度和双重任务成本并没有区分跌倒和不跌倒的人。最好的跌倒预测模型支持这样的观点，即老年人可能会因为各种平衡和步态障碍而摔倒。
Objective measures of balance and gait have the potential to improve prediction of future fallers because balance and gait impairments are common precursors. We used the Instrumented Stand and Walk Test (ISAW) with wearable, inertial sensors to maximize the domains of balance and gait evaluated in a short test. We hypothesized that ISAW objective measures across a variety of gait and balance domains would improve fall prediction beyond history of falls and better than gait speed or dual-task cost on gait-speed. We recruited 214 high-functioning older men (mean 82 years), of whom 91 participants (42.5%) had one or more falls in the 12 months following the ISAW test. The ISAW test involved 30 s of stance followed by a 7-m walk, turn, and return. We examined regression models for falling using 17 ISAW metrics, with and without age and fall history, and characterize top-performing models by AUC and metrics included. The ISAW test improved distinguishing between future fallers and non-fallers compared to age and history of falls, alone (AUC improved from 0.69 to 0.75). Models with 1 ISAW metric usually included a postural sway measure, models with 2 ISAW measures included a turning measure, models with 3 ISAW measures included a gait variability measure, and models with 4 or 5 measures added a gait initiation measure. Gait speed and dual-task cost did not distinguish between fallers and non-fallers in this high-functioning cohort. The best fall-prediction models support the notion that older people may fall due to a variety of balance and gait impairments.
