BACKGROUND: Fear of falling (FoF) is prevalent among older adults, particularly women, and is a known factor increasing fall risk during movement. FoF may naturally arise after the first fall incident as well as long before the first fall occurs. This study examined how FoF intensity affects static balance and transitional locomotor tasks in 81 healthy women aged 60 and older. METHODS: Participants were divided into LOW, MODERATE, and HIGH FoF groups based on their Falls Efficacy Scale-International (FES-I) scores. Static balance was measured by center of pressure velocity (vCOP), while transitional tasks were assessed through transit time (TT), double support period (DSP), and stability times (S1-the time needed to destabilize the body before taking a step and S2- the time required to stabilize the position after taking a step) under unimpeded transition on a flat surface, obstacle clearance, step-up, and step-down conditions. RESULTS: The findings showed no significant differences in static balance (vCOP) across FoF groups. However, the HIGH FoF group took longer to complete transitional tasks, with significantly increased TT, DSP, and S1 compared to the MODERATE group, particularly during obstacle clearance and step-up/down movements. This suggests that individuals with higher FoF take a more cautious approach, prioritizing stability over speed. No significant differences in S2 were found, indicating that FoF does not affect balance recovery after a step. CONCLUSION: The study concludes that while FoF does not impair static balance, it significantly impacts movement initiation and execution in transitional tasks. Prolonged preparation time (S1) in the HIGH FoF group highlights the role of fear in delaying movement. These findings are important for designing interventions to reduce FoF and prevent falls in older adults.
背景:害怕跌倒(FoF)在老年人中普遍存在,尤其是女性,并且是运动期间增加跌倒风险的一个已知因素。FoF可能在首次跌倒事件后自然出现,也可能在首次跌倒发生之前很久就出现。本研究调查了FoF强度如何影响81名60岁及以上健康女性的静态平衡和过渡性运动任务。 方法:根据国际跌倒效能量表(FES-I)得分,将参与者分为低、中、高FoF组。通过压力中心速度(vCOP)测量静态平衡,而过渡性任务则通过在平坦表面上无障碍过渡、越过障碍物、上台阶和下台阶条件下的过渡时间(TT)、双支撑期(DSP)和稳定时间(S1——迈出一步前使身体失去平衡所需的时间,以及S2——迈出一步后稳定姿势所需的时间)进行评估。 结果:研究结果显示,各FoF组在静态平衡(vCOP)方面没有显著差异。然而,高FoF组完成过渡性任务的时间更长,与中等FoF组相比,TT、DSP和S1显著增加,尤其是在越过障碍物和上/下台阶动作期间。这表明FoF较高的个体采取更谨慎的方法,将稳定性置于速度之上。未发现S2有显著差异,表明FoF不影响迈出一步后的平衡恢复。 结论:该研究得出结论,虽然FoF不会损害静态平衡,但它会显著影响过渡性任务中的运动启动和执行。高FoF组较长的准备时间(S1)突出了恐惧在延迟运动方面的作用。这些发现对于设计减少FoF和预防老年人跌倒的干预措施具有重要意义。
