A major purpose of investigating the plantar pressure in patients with pain or those at risk for skin injury is to reduce the pressure below metatarsal heads, specially first and second metatarsal heads. The aim of this article is to evaluate the effects of the socks structures on the changes in plantar dynamic pressure. In this study, seven socks types with different structures for the sole area were produced. The Gaitview AFA-50 system, a force plate, was used to measure the plantar dynamic pressure of 10 participants. The barefoot plantar dynamic pressure distribution was compared with the plantar dynamic pressure distribution with socks by two independent samples test on various zones of the foot and on different genders using SPSS software. Mann-Whitney tests were used to determine specific significant differences. The obtained results showed that the main trend was to redistribute the plantar dynamic pressure from the higher plantar pressure zones (toe and first through forth metatarsal bone regions) were decreased and as a result the plantar pressure toward the relatively lower pressure zones (fifth metatarsal bone and midfoot regions). In comparison with the barefoot condition, the cross miss structure reduced the mean pressure in the critical region of the foot (first metatarsal) for male and female subjects ( p < 0.05) and also the mock rib structure reduced the mean pressure for female subjects ( p < 0.05). In general, the results suggested wearing the socks because the socks make the plantar pressure redistributed from high to low plantar pressure zones. The results of this research indicated that wearing socks with cross miss and mock rib structures will reduce the mean plantar pressure values in forefoot area in comparison with the barefoot condition.
研究疼痛患者或有皮肤损伤风险患者足底压力的一个主要目的是降低跖骨头下方的压力，特别是第一和第二跖骨头下方的压力。本文的目的是评估袜子结构对足底动态压力变化的影响。在本研究中，制作了七种鞋底区域结构不同的袜子。使用测力板Gaitview AFA - 50系统测量10名参与者的足底动态压力。通过SPSS软件对足部不同区域和不同性别的两个独立样本进行测试，比较了赤足状态下的足底动态压力分布与穿着袜子时的足底动态压力分布。使用曼 - 惠特尼检验来确定具体的显著差异。所得结果表明，主要趋势是将足底动态压力从较高压力区域（脚趾以及第一至第四跖骨区域）重新分布，这些区域的压力降低，结果足底压力朝着相对较低压力区域（第五跖骨和足中部区域）转移。与赤足状态相比，交叉错纹结构降低了男性和女性受试者足部关键区域（第一跖骨）的平均压力（p < 0.05），并且仿肋骨结构降低了女性受试者的平均压力（p < 0.05）。总体而言，结果表明穿着袜子是因为袜子能使足底压力从高压力区域重新分布到低压力区域。本研究结果表明，与赤足状态相比，穿着具有交叉错纹和仿肋骨结构的袜子将降低前足区域的平均足底压力值。
