摘要：

目的利用健康女性足部有限元模型，對(duì)穿不同高度高跟鞋的足部生物力學(xué)特性進(jìn)行數(shù)值模擬，得到應(yīng)力和位移變化數(shù)據(jù)。方法對(duì)健康女性受試者的足部斷層掃描圖像進(jìn)行三維逆向重建，建立足部皮膚和骨骼的綜合有限元模型，分別模擬受試者穿1 cm、2 cm、4 cm、6 cm、8 cm、10 cm等不同高度高跟鞋時(shí)足部的應(yīng)力和位移數(shù)據(jù)。結(jié)果鞋跟高度為0～2 cm時(shí)，足部所受位移和應(yīng)力最小，最大位移為8.42 mm左右，最大應(yīng)力為50.3 MPa左右；當(dāng)鞋跟高度在4～8 cm時(shí)，足部最大變形位于8.43 ～8.45 mm之間，最大應(yīng)力位于51.7 MPa左右；當(dāng)鞋跟高度達(dá)到 10 cm時(shí)，足部最大位移增至8.47 mm，最大應(yīng)力達(dá)到61.28 MPa。結(jié)論當(dāng)鞋跟高度超過(guò)8 cm時(shí)，足部的最大應(yīng)力和最大位移急劇增加，且最大變形出現(xiàn)在踝關(guān)節(jié)處。為了保證足部的安全和健康，建議女性選擇0～8 cm的高跟鞋，研究結(jié)果可同時(shí)為臨床上足部相關(guān)疾病的研究提供科學(xué)數(shù)據(jù)支撐。

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 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 when 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 0-2 cm, the displacement and stress on the foot are the smallest, the maximum displacement is about 8.42 mm, and the maximum stress is about 50.3 MPa; when the heel height is 4-8 cm, the maximum deformation of the foot is 8.43 mm to 8.45 mm, the maximum stress is about 51.7 MPa; when the heel height reaches 250px, 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.
