Flatfoot (pes planus) is a common foot deformity, and its causes are mainly related to age, gender, weight, and genetics. Previous studies have shown that custom-made insoles could have a positive effect in improving plantar pressure and symptoms in individuals with flexible flatfeet, but it remains to be explored whether they can still show benefits in daily walking on different slopes.
This study aims to investigate a custom-made insole based on plantar pressure redistribution and to verify its effectiveness by gait analysis on different slopes.
We recruited 10 subjects and compared the peak pressure and impulse in each area between custom-made insole (CI) and ordinary insole (OI) groups.
The results illustrate that CI raises the pressure in T area, improves the ability of the subjects to move forward in the slope walking, which was beneficial to gait stability.
The redistribution of pressure in MF and MH area is promoted to provide active protection for subjects. Meanwhile, CI could decrease the impulse in MF area during uphill and level walking, which effectively reduces the accumulation of fatigue during gait. Moreover, avoiding downhill walking could be able to protect foot from injury in daily life.
扁平足（足弓平坦）是一种常见的足部畸形，其病因主要与年龄、性别、体重和遗传有关。既往研究表明，定制鞋垫可改善柔韧性扁平足患者的足底压力和症状，但在不同坡度的日常行走中是否仍能获益仍有待探讨。
本研究旨在基于足底压力分布设计一种定制鞋垫，并通过不同坡度下的步态分析验证其有效性。
我们招募了 10 名受试者，比较了定制鞋垫（CI）和普通鞋垫（OI）组在各个区域的峰值压力和冲量。
结果表明，CI 增加了 T 区的压力，提高了受试者在斜坡行走中的前进能力，有利于步态稳定性。
MF 和 MH 区域的压力重新分布为受试者提供了主动保护。同时，CI 可减少上坡和平地行走时 MF 区域的冲量，有效减少步态过程中的疲劳积累。此外，避免下坡行走可在日常生活中保护足部免受损伤。
