患有脚趾畸形的老年人已被确定跌倒的风险增加。然而，人们对可能导致这种风险增加的生物力学变化知之甚少。因此，本研究的目的是确定患有拇外翻和较小脚趾畸形的老年人与没有脚趾畸形的人相比是否表现出不同的步态、平衡和足底压力特征。对 312 名社区居住的老年男性和女性进行了拇外翻和小脚趾畸形的评估。使用 GAITrite (R) 系统测量时空步态参数，使用摇摆计评估两个表面上的姿势摇摆，并使用 Emed-AT4 压力板测量动态足底压力分布。结果表明，尽管脚趾畸形对时空步态特征或姿势摇摆没有影响，但患有拇外翻的老年人 (n = 36) 和较小脚趾畸形 (n = 71) 的前足足底压力模式发生了改变。这些发现表明，脚趾畸形会改变行走时脚下的重量分布，但脚趾畸形和跌倒之间的关系可能是由时空步态参数变化或姿势摇摆受损以外的因素介导的。 (C) 2011 Elsevier B.V. 保留所有权利。
Older people with toe deformities have been identified as having an increased risk of falling. Little is known, however, about the biomechanical changes that might contribute to this increased risk. Therefore, the purpose of this study was to determine whether older people with hallux valgus and lesser toe deformities displayed different gait, balance and plantar pressure characteristics compared to individuals without toe deformities. The presence of hallux valgus and lesser toe deformities were assessed for 312 community-dwelling older men and women. Spatiotemporal gait parameters were measured using the GAITrite (R) system, postural sway was assessed on two surfaces using a sway-meter and dynamic plantar pressure distribution was measured using an Emed-AT4 pressure plate. The results indicated that, although there were no effects of toe deformities on spatiotemporal gait characteristics or postural sway, older people with hallux valgus (n = 36) and lesser toe deformities (n = 71) were found to display altered forefoot plantar pressure patterns. These findings suggest that toe deformities alter weight distribution under the foot when walking, but that the relationship between toe deformities and falls may be mediated by factors other than changes in spatiotemporal gait parameters or impaired postural sway.
