Biomechanical dysfunction of the foot is most common cause of plantar fascia disorder and obesity and increasing age are well-known risk factors. Due to being inexpensive and quick, ultrasound imaging techniques are considered the modality of choice to assess plantar fascia. The aim of this study was to investigate the effect of age and body mass index (BMI) on sonographic findings of plantar fascia in normal population. Ultrasonography was used to measure the plantar fascia thickness of 148 healthy adults (54 males, 36.5% and 94 females, 63.5%) during a period of one year. The age, BMI, and walking distance of each participant were recorded and statistically analyzed. The mean plantar fascia thicknesses at 0.5, 1.0, and 2.0 cm distal to the insertion of the plantar fascia were 1.76 ± 0.32 mm, 2.50 ± 0.50 mm and 2.11 ± 0.41 mm respectively. The mean plantar fascia thickness for individuals ≥45 years and BMI ≥25 were significantly higher (p < .001) compared to individuals <45 years and BMI <25. In a normal population, the thickness of the plantar fascia determined by ultrasound measurement was less than 3 mm. We recommend using the position 1.0 cm distal to the calcaneal insertion of the plantar fascia as the reference point for diagnosing plantar fasciitis. The thickness of plantar fascia was significantly increased with age and BMI whereas gender, walking activity, exercise and running did not seem to affect the plantar fascia thickness.
足部生物力学功能障碍是足底筋膜疾病最常见的原因，而肥胖和年龄增长是众所周知的风险因素。由于超声成像技术价格低廉且操作快速，因此被认为是评估足底筋膜的首选方式。本研究的目的是调查年龄和体重指数（BMI）对正常人群足底筋膜超声检查结果的影响。在一年的时间里，使用超声检查测量了148名健康成年人（54名男性，占36.5%；94名女性，占63.5%）的足底筋膜厚度。记录并统计分析了每位参与者的年龄、BMI和步行距离。在足底筋膜附着点远端0.5厘米、1.0厘米和2.0厘米处，足底筋膜的平均厚度分别为1.76±0.32毫米、2.50±0.50毫米和2.11±0.41毫米。与年龄小于45岁且BMI小于25的个体相比，年龄≥45岁且BMI≥25的个体的足底筋膜平均厚度显著更高（p<0.001）。在正常人群中，通过超声测量确定的足底筋膜厚度小于3毫米。我们建议将足底筋膜跟骨附着点远端1.0厘米处作为诊断足底筋膜炎的参考点。足底筋膜厚度随年龄和BMI的增加而显著增加，而性别、步行活动、锻炼和跑步似乎并未影响足底筋膜厚度。
