本研究的目的是探讨高、正常和低足弓足结构个体的第一跖趾关节（MTP）运动和灵活性以及足底负荷。高、正常和低牙弓的无症状个体（n=61）参与了本研究。足部结构采用踝外翻指数（MVI）和足弓高度指数（AHI）进行量化。第一MTP关节的灵活性进行了测量，使用一个专门构造的夹具。行走时拇趾、第一和第二跖骨下的峰值压力使用足压计进行评估。采用Bonferroni调整事后比较的单因素ANOVA评估组间MVI、AHI、第1节MTP早期和晚期坐立和站立关节灵活性、背屈峰值（DF）以及拇趾、第1和第2跖骨下峰值压力的差异。逐步线性回归被用来确定预测的拇趾负荷。在MVI（F2，56=15.4，p<0.01）、第1次MTP坐立（F2，57=3.7，p=0.03）和站立（F2，57 = 3.7，p=0.03）的晚期灵活性方面发现了显著的组间差异。事后比较表明，第一MTP后期灵活性坐在低拱的个人相比，高拱结构显着更高，和第一MTP后期灵活性站在低拱的个人相比，正常的拱结构显着更高。逐步回归分析表明，MVI和第一MTP联合早期灵活性在坐解释约20%的变化，在拇峰压力。我们的研究结果提供了客观的证据表明，个人与低弓显示增加第一MTP关节晚期灵活性与正常的弓结构的个人相比，后足对齐和第一MTP关节灵活性影响拇趾负荷。
The purpose of our study was to examine 1st metatarsophalangeal (MTP) joint motion and flexibility and plantar loads in individuals with high, normal and low arch foot structure. Asymptomatic individuals (n=61), with high, normal and low arches participated in this study. Foot structure was quantified using malleolar valgus index (MVI) and arch height index (AHI). First MTP joint flexibility was measured using a specially constructed jig. Peak pressure under the hallux, 1st and 2nd metatarsals during walking was assessed using a pedobarograph. A one-way ANOVA with Bonferroni-adjusted post-hoc comparisons was used to assess between-group differences in MVI, AHI, Early and Late 1st MTP joint flexibility in sitting and standing, peak dorsiflexion (DF), and peak pressure under the hallux, 1st and 2nd metatarsals. Stepwise linear regression was used to identify predictors of hallucal loading. Significant between-group differences were found in MVI (F2,56=15.4, p<0.01), 1st MTP late flexibility in sitting (F2,57=3.7, p=0.03), and standing (F2,57=3.7, p=0.03). Post-hoc comparisons demonstrated that 1st MTP late flexibility in sitting was significantly higher in individuals with low arch compared to high arch structure, and that 1st MTP late flexibility in standing was significantly higher in individuals with low arch compared to normal arch structure. Stepwise regression analysis indicated that MVI and 1st MTP joint early flexibility in sitting explain about 20% of the variance in hallucal peak pressure. Our results provide objective evidence indicating that individuals with low arches show increased 1st MTP joint late flexibility compared to individuals with normal arch structure, and that hindfoot alignment and 1st MTP joint flexibility affect hallucal loading.
