Musculoskeletal foot disorders have a high incidence among overweight and obese individuals. One of the important factors causing this high incidence may be plantar fascia and heel pad (HP)-related mechanical changes occurring in these individuals. The aim of the present study was to investigate the plantar fascia and HP stiffness and thickness parameters in overweight and obese individuals and compare these values with those of normal-weight individuals.
This study was carried out in 87 (52 female, 35 male) healthy sedentary individuals between the ages of 19 and 58 years (34 ± 11 years). Participants were subsequently categorized according to body mass index (BMI) as normal weight (18.5 kg/m < BMI < 25 kg/m) or overweight and obese (BMI ≥25 kg/m). Plantar fascia and HP thickness and stiffness were measured with an ultrasonography device using a linear ultrasonography probe.
Overweight and obese individuals had higher HP thickness ( P < .001), plantar fascia thickness ( P = .001), heel pad microchamber layer (MIC) stiffness ( P < .001), and heel pad macrochamber layer (MAC) stiffness ( P < .001), whereas they had lower plantar fascia stiffness ( P < .001) compared with the individuals with normal weight. BMI had a moderate correlation with HP thickness ( P < .001, r = 0.500), plantar fascia thickness ( P = .001, r = 0.536), MIC stiffness ( P < .001, r = 0.496), and MAC stiffness ( P < .001, r = 0.425). A negative and moderate correlation was found between BMI and plantar fascia stiffness ( P < .001, r = -0.439).
Increased BMI causes a decrease in the stiffness of plantar fascia and an increase in the thickness of the plantar fascia as well as the thickness and stiffness of HP. Increased body mass could cause changes in the mechanical properties of HP and plantar fascia.

肌肉骨骼足部疾病在超重和肥胖个体中发病率较高。导致这种高发病率的重要因素之一可能是这些个体中发生的与足底筋膜和足跟垫（HP）相关的力学变化。本研究的目的是调查超重和肥胖个体的足底筋膜和HP的硬度及厚度参数，并将这些值与正常体重个体的值进行比较。
本研究对87名（52名女性，35名男性）年龄在19至58岁（34±11岁）的健康久坐个体进行。随后根据体重指数（BMI）将参与者分为正常体重（18.5kg/m²＜BMI＜25kg/m²）或超重和肥胖（BMI≥25kg/m²）。使用线性超声探头通过超声设备测量足底筋膜和HP的厚度及硬度。
与正常体重个体相比，超重和肥胖个体的HP厚度更高（P＜0.001）、足底筋膜厚度更高（P = 0.001）、足跟垫微腔层（MIC）硬度更高（P＜0.001）以及足跟垫大腔层（MAC）硬度更高（P＜0.001），而他们的足底筋膜硬度更低（P＜0.001）。BMI与HP厚度（P＜0.001，r = 0.500）、足底筋膜厚度（P = 0.001，r = 0.536）、MIC硬度（P＜0.001，r = 0.496）和MAC硬度（P＜0.001，r = 0.425）呈中度相关。BMI与足底筋膜硬度之间存在负向中度相关（P＜0.001，r = -0.439）。
BMI增加会导致足底筋膜硬度降低，以及足底筋膜厚度、HP厚度和硬度增加。体重增加可能会导致HP和足底筋膜力学性能的变化。
