This study aimed to investigate the gait pattern of elderly women with and without fall-history, with high and low fear of falling, when exposed to a disturbing factor. Forty-nine elderly women without cognitive impairment agreed to participate. Participants were divided into four groups, considering the history of falls and fear of falling. Three-dimensional gait analysis was performed to assess gait kinematics before and after exposure to the fictional disturbing factor (psychological and non-motor agent). After being exposed to the perturbation, all showed shorter step length, stride length and slower walking speed. Those without fall-history and with high fear of falling showed greater changes and lower Gait Profile Score. The gait changes shown in the presence of a fear-of-falling causing agent led to a cautious gait pattern in an attempt to increase protection. However, those changes increased fall-risk, boosted by fear of falling. www.residentialclinics.gov.br, identifier: RBR-35xhj5.
本研究旨在调查有跌倒史和无跌倒史、跌倒恐惧程度高和低的老年女性在暴露于干扰因素时的步态模式。49名无认知障碍的老年女性同意参与。根据跌倒史和跌倒恐惧程度，将参与者分为四组。在暴露于虚构的干扰因素（心理和非运动因素）之前和之后，进行三维步态分析以评估步态运动学。暴露于干扰因素后，所有人的步长、步幅均缩短，步行速度减慢。无跌倒史且跌倒恐惧程度高的人表现出更大的变化和更低的步态轮廓评分。在存在导致跌倒恐惧的因素时所表现出的步态变化导致了一种谨慎的步态模式，试图增加保护。然而，这些变化增加了跌倒风险，因跌倒恐惧而加剧。www.residentialclinics.gov.br，标识符：RBR-35xhj5。
