UNASSIGNED: Twenty asymptomatic participants with planus (n = 23 feet) and rectus (n = 17 feet) foot types were enrolled. Several parameters of static foot structure (arch height index, arch height flexibility, first metatarsophalangeal joint flexibility, and first ray mobility) were measured. Participants were further stratified into groups with nonhypermobile (n = 26 feet) and hypermobile (n = 14 feet) first rays. First ray mobility ≥8 mm was used to define \"first ray hypermobility\". Generalized estimating equations, best-fit regression lines, and stepwise linear regression were used to identify significant differences and predictors between the study variables.
UNASSIGNED: Overall, 86% of subjects categorized with first ray hypermobility exhibited a planus foot type. Arch height flexibility, weightbearing first ray mobility, and first metatarsophalangeal joint flexibility showed no significant between-group differences. However, weightbearing ray mobility and first metatarsophalangeal joint laxity were associated with partial weightbearing first ray mobility, accounting for 38% of the model variance.
UNASSIGNED: The planus foot type was found to be associated with first ray hypermobility. Furthermore, weightbearing first ray mobility and first metatarsophalangeal joint laxity were predictive of partial weightbearing first ray mobility, demonstrating an interaction between the translation and rotational mechanics of the first ray.
UNASSIGNED: Association of first ray hypermobility with foot type and first metatarsophalangeal joint flexibility may help understand the sequela to symptomatic pathologies of the foot.
UNASSIGNED:招募了20名无症状的扁平疣(n=23英尺)和直肌(n=17英尺)足部类型的参与者。静态足部结构的几个参数(足弓高度指数,拱形高度的灵活性,第一跖趾关节的灵活性,和第一射线迁移率)进行测量。参与者进一步分为非超移动(n=26英尺)和超移动(n=14英尺)第一射线组。第一射线迁移率≥8mm用于定义“第一射线超迁移率”。广义估计方程,最佳拟合回归线,和逐步线性回归用于确定研究变量之间的显著差异和预测因素。
未经评估:总的来说,86%的被归类为第一射线过度活动的受试者表现出扁平足类型。拱门高度灵活性,负重第一射线迁移率,和第一meta趾关节的柔韧性在组间没有显着差异。然而,负重射线迁移率和第一meta趾关节松弛与部分负重射线迁移率相关,占模型方差的38%。
未授权:发现扁平足类型与第一射线过度活动有关。此外,负重第一射线迁移率和第一meta趾关节松弛是部分负重第一射线迁移率的预测因素,展示了第一射线的平移和旋转力学之间的相互作用。
UNASSIGNED:第一射线过度活动与足部类型和第一掌趾关节灵活性的关联可能有助于了解足部症状性病变的后遗症。
