Abstract

Although there is evidence suggesting that obesity alters plantar pressure distribution, the specific effects of certain body mass index (BMI) ranges on pedobarographic measures in healty individuals has been poorly investigated. A cross-sectional study with 167 healthy participants was conducted to assess plantar pressure changes across 4 BMI ranges: Under/normal weight (NW), overweight (OW), obese (OB), severe obese (SO). Subjects walked on the Footscan® pressure plate at a self-selected speed, and peak plantar pressure (PPP), load rate, and contact area values were recorded. The foot was divided into 10 zones: hallux (T1), toes 2–5 (T2-5), metatarsals 1–5 (M1-M5), midfoot (MF), medial hindfoot (MH) and lateral hindfoot (LH). PPP underneath M2-M4 was lowest in the NW group (p = 0.011), and although PPP values for the SO group were lower than those for the OW and OB groups, these differences were not statistically significant. Load rate values of M2-M3 were lower in both the NW and SO groups (p = 0.008) compared to the OW and OB groups. In addition, the metatarsal load rate values for the SO group were generally lower than those for the NW group. The total metatarsal contact area of both the NW and SO groups was lower (p = 0.019) than that of the OW and OB groups in both feet. These findings suggest that as BMI increases, PPP, load rate, and contact area in the middle metatarsal region initially increase, stabilize early in obesity, and then decrease at advanced stages, indicating a shift of the load to the midfoot.

体重指数范围对足底摄影评估的矛盾影响

尽管有证据表明肥胖会改变足底压力的分布，但对于某些体重指数（BMI）范围对健康人足底压力测量的具体影响却鲜有研究。我们对 167 名健康参与者进行了一项横断面研究，以评估 4 种体重指数范围的足底压力变化：体重不足/正常（NW）、超重（OW）、肥胖（OB）和严重肥胖（SO）。受试者以自选速度在 Footscan® 压力板上行走，并记录足底压力峰值 (PPP)、负荷率和接触面积值。足部被分为 10 个区域：脚掌（T1）、脚趾 2-5（T2-5）、跖骨 1-5（M1-M5）、中足（MF）、后足内侧（MH）和后足外侧（LH）。西北组 M2-M4 下方的 PPP 值最低（p = 0.011），虽然 SO 组的 PPP 值低于 OW 组和 OB 组，但这些差异在统计学上并不显著。与 OW 组和 OB 组相比，NW 组和 SO 组的 M2-M3 负荷率值均较低（p = 0.008）。此外，SO 组的跖骨负荷率值普遍低于 NW 组。NW组和SO组的双脚总跖骨接触面积均低于OW组和OB组（P = 0.019）。这些发现表明，随着体重指数（BMI）的增加，中跖骨区域的PPP、负荷率和接触面积最初会增加，在肥胖早期会趋于稳定，然后在晚期会减少，这表明负荷转移到了中足。
