Postural and walking instabilities contribute to falls in older adults. Given that shoes affect human locomotor stability and that visual, cognitive and somatosensory systems deteriorate during aging, we aimed to: (1) compare the effects of footwear type on stability and mobility in persons with a history of falls, and (2) determine whether the effect of footwear type on stability is altered by the absence of visual input or by an additional cognitive load. Thirty participants performed standing and walking trials in three footwear conditions, i.e. conventional shoes, minimal shoes, and barefoot. The outcomes were: (1) postural stability (movement of the center of pressure during eyes open/closed), (2) walking stability (Margin of Stability during normal/dual-task walking), (3) mobility (the Timed Up and Go test and the Star Excursion Balance test), and (4) perceptions of the shoes (Monitor Orthopaedic Shoes questionnaire). Participants were more stable during standing and walking in minimal shoes than in conventional shoes, independent of visual or walking condition. Minimal shoes were more beneficial for mobility than conventional shoes and barefoot. This study supports the need for longitudinal studies investigating whether minimal footwear is more beneficial for fall prevention in older people than conventional footwear.
姿势和行走不稳会导致老年人跌倒。鉴于鞋子会影响人类的行走稳定性,且视觉、认知和体感系统会随着年龄的增长而恶化,我们旨在:(1)比较不同鞋类对有跌倒史者稳定性和活动能力的影响,(2)确定在缺乏视觉输入或额外认知负荷的情况下,鞋类类型对稳定性的影响是否会发生变化。30 名参与者在三种鞋类条件下进行了站立和行走试验,即常规鞋、极简鞋和赤脚。结果为:(1)姿势稳定性(睁眼/闭眼时的压力中心移动),(2)行走稳定性(正常/双重任务行走时的稳定裕度),(3)活动能力(计时起立行走测试和星状伸展平衡测试),以及(4)对鞋子的感知(监测矫形鞋问卷)。在站立和行走时,参与者穿着极简鞋比穿着常规鞋更稳定,无论视觉或行走条件如何。与常规鞋和赤脚相比,极简鞋更有利于提高活动能力。本研究支持需要进行纵向研究,以调查在老年人中,极简鞋是否比常规鞋更有益于预防跌倒。
