摘　　要：目的利用剪切波弹性成像技术比较不同年龄段正常人及足底筋膜炎患者的足底筋膜的厚度和硬度。方法对23名足底筋膜炎患者和30例健康志愿者进行剪切波弹性超声检查,测量足底筋膜跟骨止点及距离跟骨止点1 cm处的厚度和弹性模量值。结果老年组足底筋膜明显比年轻组厚(P=0.005),弹性模量值明显比年轻组小(P=0.000)。足底筋膜炎组足底筋膜厚度明显比老年组厚(P=0.001),弹性模量值明显比老年组小(P=0.000)。足底筋膜炎组的足底筋膜跟骨止点处弹性模量值比距离跟骨止点处1 cm的筋膜弹性值低(P=0.000),而健康志愿者年轻组和老年组的两个位置的弹性模量差异无统计学意义(P=0.172,P=0.126)。结论剪切波弹性成像能定量评估足底筋膜的硬度,足底筋膜的硬度随年龄增加而变小,足底筋膜炎的筋膜硬度较正常筋膜变小。Objective To assess the stiffness and thickness of the plantar fascia using shear wave elastography （SWE） in healthy volunteers of different ages and in patients with plantar fasciitis. Methods The bilateral feet of 30 healthy volunteers and 23 patients with plantar fasciitis were examined with SWE. The plantar fascia thickness and elasticity modulus value were measured at the insertion of the calcaneus and at 1 cm from the insertion. Results The elderly volunteers had a significantly greater plantar fascia thickness measured using conventional ultrasound （P=0.005） and a significantly lower elasticity modulus value than the young volunteers （P=0.000）. The patients with fasciitis had a significantly greater plantar fascia thickness （P=0.001） and a lower elasticity modulus value than the elderly volunteers （P=0.000）. The elasticity modulus value was significantly lower at the calcaneus insertion than at 1 cm from the insertion in patients with fasciitis （P=0.000） but showed no significantly difference between the two points in the elderly or young volunteers （P=0.172, P=0.126）. Conclusion SWE allows quantitative assessment of the stiffness of the plantar fascia, which decreases with aging and in patients with plantar fasciitis.
