Clinicians and footwear manufacturers often advise young children to wear soft-soled footwear when they are first learning to walk. There is limited evidence as to why this advice is given, and if soft-soled shoes are as close to barefoot as thought.
What are the differences in spatiotemporal measures of gait during walking and running in three common types of children's footwear with a soft-soled compared to barefoot in young children?
The study used a quasi-experimental design, with the condition order randomised using a Latin square sequence. Forty-seven children were recruited (2 - 4 years). Participants walked or ran the length of a GAITrite mat in a randomized order for barefoot and soft-soled sneaker, boot and sandal conditions. Linear regression analyses were used to investigate the main effect of each soft-soled footwear compared to bare feet in the different gait parameters.
For walking and running trials, cadence decreased whereas step time and stride length increased in all footwear types compared to the barefoot condition. While wearing sneakers and sandals increased the stance percentage for walking and running trials, compared to barefoot, this difference was only apparent during the running trial for the boots. Likewise, although double support time increased for both the boots and sneakers in walking and running, compared to barefoot, this difference was only observed in the sandals during walking.
This research found that various types of soft-soled footwear impacted gait compared to the barefoot condition, with some differences seen between walking and running trials. These findings challenge the assumption that soft-soled footwear facilitate a similar gait to barefoot walking and running, although the clinical significance of these differences is unknown.
临床医生和制鞋商通常建议初学走路的幼儿穿软底鞋。至于为什么会有这样的建议,以及软底鞋是否像人们认为的那样接近赤脚,目前证据有限。
与赤脚相比,软底鞋在三种常见类型的儿童鞋中的哪一种最接近赤脚,在幼儿行走和跑步时步态的时空测量有何不同?
该研究采用准实验设计,使用拉丁方序列随机化条件顺序。招募了 47 名儿童(2-4 岁)。参与者以随机顺序赤脚和软底运动鞋、靴子和凉鞋在 GAITrite 垫上行走或跑步。线性回归分析用于研究与赤脚相比,每种软底鞋在不同步态参数中的主要影响。
在行走和跑步试验中,与赤脚相比,所有鞋类的步频降低,而步幅时间和步长增加。虽然与赤脚相比,穿运动鞋和凉鞋会增加行走和跑步试验的站立百分比,但这种差异仅在跑步试验中靴子中明显。同样,虽然与赤脚相比,靴子和运动鞋在行走和跑步时的双支撑时间都增加了,但这种差异仅在行走时的凉鞋中观察到。
本研究发现,与赤脚相比,各种类型的软底鞋都会影响步态,行走和跑步试验之间存在一些差异。这些发现挑战了软底鞋可以促进类似于赤脚行走和跑步的步态的假设,尽管这些差异的临床意义尚不清楚。
