摘要
目的利用健康女性足部有限元模型,对穿不同高度高跟鞋的足部生物力学特性进行数值模拟,得到应力和位移变化数据。方法对健康女性受试者的足部断层扫描图像进行三维逆向重建,建立足部皮肤和骨骼的综合有限元模型,分别模拟受试者穿1 cm、2 cm、4 cm、6 cm、8 cm、10 cm等不同高度高跟鞋时足部的应力和位移数据。结果鞋跟高度为0~2 cm时,足部所受位移和应力最小,最大位移为8.42 mm,最大应力为50.3 MPa;当鞋跟高度在4~8 cm时,足部最大变形为8.43~8.45 mm,最大应力51.7 MPa;当鞋跟高度达到10 cm时,足部最大位移增至8.47 mm,最大应力达到61.28 MPa。结论当鞋跟高度超过8 cm时,足部的最大应力和最大位移急剧增加,且最大变形出现在踝关节处。为了保证足部的安全和健康,建议女性选择0~8 cm的高跟鞋,研究结果可同时为临床上足部相关疾病的研究提供科学数据支撑。
Objective Using the finite element model of healthy women’s feet,the biomechanical characteristics of the feet wearing high heels of different heights are numerically simulated,and the stress and displacement change data are obtained.Methods We perform three-dimensional reverse reconstruction of tomographic images of the feet of healthy female subjects,establish a comprehensive finite element model of foot skin and bones,simulate the stress and displacement data of the subject’s foot as wearing high-heeled shoes of different heights such as 1 cm,2 cm,4 cm,6 cm,8 cm,and 10 cm.Results When the heel height is 0 to 2 cm,the displacement and stress on the foot are the smallest,the maximum displacement is 8.42 mm,and the maximum stress is 50.3 MPa.When the heel height is 4 cm to 8 cm,the maximum deformation of the foot is 8.43 mm to 8.45 mm,the maximum stress is 51.7 MPa.When the heel height reaches 10 cm,the maximum displacement of the foot increases to 8.47 mm,and the maximum stress reaches 61.28 MPa.Conclusions When the heel height exceeds 8 cm,the maximum stress and maximum displacement of the foot increase sharply,and the maximum deformation occurs at the ankle joint.In order to ensure the safety and health of the feet,it is recommended that women choose 0 cm to 8 cm high heels.The research results can also provide scientific data support for clinical research on foot-related diseases.
