老年人不能安全地跨过障碍物，除非他们正确地估计他们的身体能力能够成功地跨过动作。因此，对跨过障碍物的能力的不正确估计（高估）可能导致严重事故，例如老年人的福尔斯跌倒。我们调查了老年人是否倾向于高估跨越能力与年轻人相比，以及这种高估跨越障碍是否与福尔斯有关。三组成年人，60-74岁（n，343），老年-老年（年龄，>74岁; n，151）和年轻（年龄，18-35岁; n，71），进行了我们最初的跨越测试（SOT）。在SOT中，参与者观察7米距离处的单杠，并估计他们可以跨过的最大高度（EH）。估计后，他们进行了真实的SOT试验，以测量实际的最大高度（AH）。我们还确定了在研究前1年内经历过福尔斯的参与者。39名12岁的成年人（11.4%）和49名老年人（32.5%）未能越过EH的标准（高估），而所有年轻人都成功了（低估）。老年人的实际工作能力（AH）与自我估计误差（EH与AH之差）呈显著负相关，表明AH（SOT能力）较低的老年人倾向于高估实际工作能力（EH > AH），反之亦然。此外，过高估计跌倒者SOT能力的参与者比例（28%）几乎是非跌倒者（16%）的两倍，跌倒者的SOT能力明显低于非跌倒者。老年人似乎没有意识到与年龄有关的身体衰退，往往高估了跨越能力。与年龄相关的跨越能力下降，以及更重要的是，对这种能力的高估或减少低估都可能增加福尔斯的潜在风险。
Older adults could not safely step over an obstacle unless they correctly estimated their physical ability to be capable of a successful step over action. Thus, incorrect estimation (overestimation) of ability to step over an obstacle could result in severe accident such as falls in older adults. We investigated whether older adults tended to overestimate step-over ability compared with young adults and whether such overestimation in stepping over obstacles was associated with falls. Three groups of adults, young-old (age, 60–74 years; n, 343), old-old (age, >74 years; n, 151), and young (age, 18–35 years; n, 71), performed our original step-over test (SOT). In the SOT, participants observed a horizontal bar at a 7-m distance and estimated the maximum height (EH) that they could step over. After estimation, they performed real SOT trials to measure the actual maximum height (AH). We also identified participants who had experienced falls in the 1 year period before the study. Thirty-nine young-old adults (11.4%) and 49 old-old adults (32.5%) failed to step over the bar at EH (overestimation), whereas all young adults succeeded (underestimation). There was a significant negative correlation between actual performance (AH) and self-estimation error (difference between EH and AH) in the older adults, indicating that older adults with lower AH (SOT ability) tended to overestimate actual ability (EH > AH) and vice versa. Furthermore, the percentage of participants who overestimated SOT ability in the fallers (28%) was almost double larger than that in the non-fallers (16%), with the fallers showing significantly lower SOT ability than the non-fallers. Older adults appear unaware of age-related physical decline and tended to overestimate step-over ability. Both age-related decline in step-over ability, and more importantly, overestimation or decreased underestimation of this ability may raise potential risk of falls.
