Information is limited about the relationships between clinical measures of static foot posture and peak plantar pressures under the medial column of the foot. The purpose was to examine these relationships during static standing and walking.
A single-group exploratory design using correlation and regression was used to determine relationships. Ninety-two healthy volunteers participated. Clinical measures of static foot posture including arch index, navicular drop and navicular drift were obtained during static standing. Peak plantar pressures under the hallux, medial forefoot, medial midfoot, and medial rearfoot were obtained during standing and walking.
Static foot posture was related to peak plantar pressures during standing and walking, but the strengths of relationships ranged from poor to fair. During standing, navicular drop was correlated (P≤0.05) with hallux (r=0.29) and medial forefoot (r=-0.17) pressures, while arch index (r=-0.17) and navicular drift (r=0.25) were correlated (P≤0.05) with hallux pressure. During walking, arch index, navicular drop and navicular drift were correlated (P≤0.05) with hallux and medial forefoot pressures (r range -0.30 to 0.41), while arch index (r=-0.15) and navicular drop (r=0.16) were correlated (P≤0.05) with medial midfoot pressure. Regression models predicted (P≤0.05) hallux (R(2)=0.08) and medial midfoot (R(2)=0.05) pressures during standing, and hallux (R(2)=0.18), medial forefoot (R(2)=0.07), and medial rearfoot (R(2)=0.05) pressures during walking.
In healthy participants, lower arch foot postures are associated with greater pressures under the hallux and medial mid-foot and lower pressures under the medial forefoot, but the strength of these relationships may be only poor to fair.
关于静态足部姿势的临床测量指标与足底内侧纵弓下的峰值足底压力之间的关系，相关信息有限。本研究旨在探讨静态站立和行走过程中的这些关系。
采用单组探索性设计，运用相关性和回归分析来确定两者之间的关系。92名健康志愿者参与了研究。在静态站立时获取静态足部姿势的临床测量指标，包括足弓指数、舟骨下降和舟骨偏移。在站立和行走过程中获取拇趾、前足内侧、中足内侧和后足内侧的峰值足底压力。
静态足部姿势与站立和行走过程中的峰值足底压力相关，但相关强度从弱到中等。站立时，舟骨下降与拇趾（r = 0.29）和前足内侧（r = -0.17）压力呈相关性（P≤0.05），而足弓指数（r = -0.17）和舟骨偏移（r = 0.25）与拇趾压力呈相关性（P≤0.05）。行走时，足弓指数、舟骨下降和舟骨偏移与拇趾和前足内侧压力呈相关性（P≤0.05）（r范围为 -0.30至0.41），而足弓指数（r = -0.15）和舟骨下降（r = 0.16）与中足内侧压力呈相关性（P≤0.05）。回归模型预测（P≤0.05）了站立时拇趾（R² = 0.08）和中足内侧（R² = 0.05）的压力，以及行走时拇趾（R² = 0.18）、前足内侧（R² = 0.07）和后足内侧（R² = 0.05）的压力。
在健康参与者中，足弓较低的足部姿势与拇趾和中足内侧下方较高的压力以及前足内侧下方较低的压力相关，但这些关系的强度可能仅为弱到中等。
