The purpose of this study was to determine if increased weight contributes to increased mean peak plantar foot pressures when foot function, deformity, and structure are controlled. Ten male and nine female volunteers without sensory neuropathy or other systemic disease were evaluated in the study. Using a repeated measures design, peak plantar foot pressures were compared using the Novel Pedar in-shoe pressure measurement system under three conditions. Baseline measurements were made while volunteers wore the standard test footwear, a thin-soled rubber oxford sneaker. The second and third test conditions involved pressure measurements with an additional 9.1 kg (20 lb) and 18.2 kg (40 lb), respectively, of weight evenly distributed in pockets on the front and back of a workout vest. There was a significant increase in mean peak plantar foot pressures under the metatarsal heads, heel, and midfoot for each incremental increase of weight (baseline vs. 9.1 kg, p < .05; 9.1 kg vs. 18.2 kg, p < .05). The authors conclude that increases in weight increased plantar foot pressures for the first metatarsal, lesser metatarsal, midfoot, and heel regions in both men and women.
本研究的目的是确定在控制足部功能、畸形和结构的情况下，体重增加是否会导致足底平均峰值压力升高。本研究评估了10名男性和9名女性志愿者，他们均无感觉神经病变或其他全身性疾病。采用重复测量设计，在三种条件下使用Novel Pedar鞋内压力测量系统比较足底峰值压力。在志愿者穿着标准测试鞋（一种薄底橡胶牛津运动鞋）时进行基线测量。第二和第三个测试条件分别涉及在健身背心的前后口袋中均匀分布额外9.1千克（20磅）和18.2千克（40磅）的重量进行压力测量。随着体重每次增加，跖骨头、足跟和足中部下方的足底平均峰值压力均显著增加（基线与9.1千克相比，p < 0.05；9.1千克与18.2千克相比，p < 0.05）。作者得出结论，体重增加会使男性和女性的第一跖骨、小跖骨、足中部和足跟区域的足底压力升高。
