Shoe attrition is inevitable as wearing time increases, which may produce diverse influences on kinematics and kinetics of lower limb joints. Excessive attrition may change support alignment and lead to deleterious impacts on the joints. The study identifies the biomechanical influences of aging shoes on lower limb joints. The shoes in the experiment were manually worn in the lateral heel. Nineteen healthy participants, including thirteen males and six females, were recruited to conduct walking experiments wearing attrition shoes (AS) and new shoes (NS) with a random order. A Vicon motion analysis system was used to collect kinematic data and ground reaction force. Kinematic and kinetic parameters of the hip, knee, and ankle joints were calculated using the Anybody Musculoskeletal Model and compared between the two conditions, AS and NS. The results showed that wearing an attrition shoe decreased the plantarflexion angle and plantarflexion moment of the ankle joint, while significantly increasing the magnitude of the first peak of the knee adduction moment and hip abduction moment and hip internal rotation moment ( < .05). The results of the study implied that wearing attrition shoes is not recommended for those people with knee problems due to increase in medial loading.
随着穿着时间的增加，鞋子磨损是不可避免的，这可能会对下肢关节的运动学和动力学产生多种影响。过度磨损可能会改变支撑对线并对关节造成有害影响。本研究确定了老化鞋子对下肢关节的生物力学影响。实验中的鞋子是在足跟外侧手动穿着的。招募了19名健康参与者，包括13名男性和6名女性，以随机顺序穿着磨损鞋（AS）和新鞋（NS）进行步行实验。使用Vicon运动分析系统收集运动学数据和地面反作用力。使用Anybody肌肉骨骼模型计算髋、膝和踝关节的运动学和动力学参数，并在AS和NS两种情况下进行比较。结果表明，穿着磨损鞋会减小踝关节的跖屈角度和跖屈力矩，同时显著增加膝关节内收力矩、髋关节外展力矩和髋关节内旋力矩第一个峰值的大小（<.05）。研究结果表明，由于内侧负荷增加，不建议有膝关节问题的人穿磨损鞋。
