The aim of this study was to evaluate the effect of textured foot orthoses on plantar pressure variables in children with autism spectrum disorders (ASDs). Thirty boys were divided into two groups based on their health status, namely: autism spectrum disorder and healthy matched controls. Plantar pressure data were captured during stance phases of shod walking with and without textured foot orthoses. Remarkably larger peak force under the toe1 and metatarsal1 and peak pressure under the toe1 and toe2-5 regions were observed in the autism group comparing with the healthy group, while lower peak force under the toe1, metatarsal1 and metatarsal2 were seen during walking with textured foot orthoses comparing with the cases of walking without them. The results showed higher values of peak pressure under metatarsal3, metatarsal4 and metatarsal5 for the textured foot orthoses walking against the cases without them. Also, analysis depicted huge reductions from pre-to-posttest for the peak pressure under toe2-5 only cases within the autism group. The reason of observing higher peak values of forces and pressures within their forefoot can potentially be their tendency to walk on their toes comparing against the healthy control children. This causes lower pressure values within all toes and the first metatarsal regions during normal walking with textured foot orthoses than walking without them. The findings revealed that the use of textured foot orthoses reduced peak pressure under toe2-5 only in the autism group. This suggests that the use of such interventions can help boys with ASDs move more safely.
本研究旨在评估纹理足底矫形器对自闭症谱系障碍（ASD）儿童足底压力变量的影响。根据健康状况，30 名男孩被分为两组：自闭症谱系障碍组和健康匹配对照组。在穿鞋和不穿鞋的情况下，分别在站立阶段采集足底压力数据。与健康组相比，自闭症组的脚趾 1 和跖骨 1 下的峰值力和脚趾 1 和脚趾 2-5 区域的峰值压力明显更大，而在穿纹理足底矫形器行走时，脚趾 1、跖骨 1 和跖骨 2 下的峰值力较低。结果表明，在使用纹理足底矫形器行走时，跖骨 3、4 和 5 下的峰值压力更高。此外，在自闭症组中，仅在脚趾 2-5 下的峰值压力在前后测试之间有很大的降低。他们前脚的力和压力峰值较高的原因可能是他们与健康对照组的儿童相比更倾向于用脚尖走路。这导致在使用纹理足底矫形器进行正常行走时，所有脚趾和第一跖骨区域的压力值都低于不使用时。研究结果表明，纹理足底矫形器仅在自闭症组中降低了脚趾 2-5 下的峰值压力。这表明此类干预措施的使用可以帮助 ASD 男孩更安全地移动。
