鞋前跷参数设计对步行生物力学特征的影响:综述与展望OA北大核心CSTPCD

In order to explore the possible effects of different toe spring parameter designs on the biomechanical characteristics of human walking,literature searches were conducted using databases such as PubMed and the China National Knowledge Infrastructure to get articles published over the past 30 years about the influence of the spring parameters on lower limb biomechanics.A total of 486 articles were retrieved,and 16 of them were ultimately included for analysis.The results showed that different design parameters could have an impact on plantar pressure,gait stability,and ankle biomechanics.The apex position can affect ankle dorsiflexion resistance by changing the resistance arm,thereby affecting ankle dorsiflexion torque and subsequently affecting Achilles tendon stress.Altering the forefoot rocker angle could reduce the dorsiflexion angle of the metatarsophalangeal joint,leading to the decreased forefoot plantar pressure.It also helps to mitigate the winding effect and relieve plantar fascia stress.However,smaller apex angles can disrupt gait stability.The benefits of different combinations of parameters for foot and ankle health vary,and it is necessary to further clarify the interactions among these parameters to ensure the application effectiveness of functional footwear design.
