BACKGROUND
Hallux valgus (HV) is one common deformity of the human foot. Metatarsal pain, gait deviation and foot function disorder may occur when HV is severe.
RESEARCH QUESTION
It was hypothesized that a 12-week minimalist shoes running intervention among mild and moderate hallux valgus males may alter foot morphology and plantar pressure distribution during walking and running.
METHODS
The foot morphology and plantar pressure data, in this study, were collected from eleven participants using the Easy-Foot-Scan (EFS) and Novel EMED force plate.
RESULTS
Compared to pre-intervention sessions, the hallux abductus angle and forefoot width decreased significantly with increased metatarsal waist girth in the post-intervention session. The peak pressure, maximum force and force time integral in the first metatarsal reduced significantly due to the distribution of plantar pressure to the central foot regions.
SIGNIFICANCE
The findings suggest that minimalist shoes may deform forefoot morphology and neutralize loading concentration for mild and moderate hallux valgus.
背景
拇外翻（HV）是一种常见的足部畸形。当拇外翻严重时，可能会出现跖骨疼痛、步态偏差和足部功能障碍。
研究问题
研究假设，对轻度和中度拇外翻男性进行为期12周的极简主义跑鞋干预，可能会改变他们行走和跑步时的足部形态和足底压力分布。
方法
在本研究中，使用Easy-Foot-Scan（EFS）和Novel EMED测力板，从11名参与者那里收集足部形态和足底压力数据。
结果
与干预前相比，干预后拇外展角和前足宽度显著减小，同时跖骨腰围增加。由于足底压力向足部中央区域分布，第一跖骨的峰值压力、最大力和力-时间积分显著降低。
意义
研究结果表明，极简主义跑鞋可能会使前足形态变形，并中和轻度和中度拇外翻的负荷集中情况。
