This study aimed to evaluate the distribution of foot pressure with the most frequently used orthopedic shoes and demonstrate the effect of offloading philosophy on the pressure distributions of rocker bottom or heel support shoes applied unilaterally or bilaterally.
Three bilateral and four unilateral, a total of seven shoe designs with sensors included in the insole were tested by the same subject in a standard acquisition protocol. Two of the unilateral and one of the bilateral shoes had heel support, while others had a rocker bottom design. A descriptive analysis was performed for each shoe and compared to a reference value obtained from a standard shoe.
Shoes with an offloading heel resulted in a greater reduction in pressure on the forefoot than other models. All other shoes increased pressure on the first metatarsophalangeal joint. Heel offloading models performed the best in forefoot offloading, and bilateral heel offloading shoes performed the best in first metatarsal offloading, with the highest scores of 83% and 82%, respectively.
This study showed that orthopedic shoes sold in pairs could reduce pressure on the forefoot at a comparable level to unilateral shoes. It supports their use to limit the disadvantages of single orthopedic shoes, such as limb length discrepancies.
本研究旨在评估最常使用的矫形鞋的足底压力分布,并展示单侧或双侧应用减载理念对鞋跟支撑或鞋跟支撑鞋的压力分布的影响。
在标准采集协议中,由同一位受试者测试了带有传感器的 7 种共 3 双双侧和 4 单侧鞋设计。其中 2 只单侧鞋和 1 只双侧鞋具有鞋跟支撑,而其他鞋具有鞋底翘起设计。对每种鞋进行描述性分析,并与标准鞋获得的参考值进行比较。
具有鞋跟卸荷功能的鞋可使前足压力降低得更多,而其他鞋则会增加第一跖趾关节的压力。所有其他鞋子都增加了第一跖骨的压力。具有卸荷鞋跟的模型在前足卸荷方面表现最佳,双侧鞋跟卸荷鞋在第一跖骨卸荷方面表现最佳,得分分别为 83%和 82%。
本研究表明,成对出售的矫形鞋可以以可与单侧鞋相媲美的水平降低前足压力,这支持了它们的使用,可以限制单只矫形鞋的缺点,例如肢体长度差异。
