Elevated patellofemoral joint stress is thought to contribute to the development and progression of patellofemoral pain syndrome. The purpose of this study was to determine if running barefoot decreases patellofemoral joint stress in comparison to shod running.
Lower extremity kinematics and ground reaction force data were collected from 22 trained runners during overground running while barefoot and in a neutral running shoe. The kinematic and kinetic data were used as input variables into a previously described mathematical model to determine patellofemoral joint stress. Knee flexion angle, net knee extension moment and the model outputs of contact area, patellofemoral joint reaction force and patellofemoral joint stress were plotted over the stance phase of the gait cycle and peak values compared using paired t tests and standardised mean differences calculated.
Running barefoot decreased peak patellofemoral joint stress by 12% (p=0.000) in comparison to shod running. The reduction in patellofemoral joint stress was a result of reduced patellofemoral joint reaction forces (12%, p=0.000) while running barefoot.
Elevated patellofemoral joint stress during shod running might contribute to patellofemoral pain. Running barefoot decreases patellofemoral joint stress.
研究认为，髌股关节压力升高与髌股疼痛综合征的发生和发展有关。本研究旨在确定与穿鞋跑步相比，赤脚跑步是否会降低髌股关节的压力。
在 22 名受过训练的跑步者进行地面跑步时，收集他们的下肢运动学和地面反作用力数据，分别在赤脚和中性跑鞋的情况下进行。将运动学和动力学数据作为输入变量输入到先前描述的数学模型中，以确定髌股关节的压力。在步态周期的站立阶段绘制膝关节弯曲角度、净膝关节伸展力矩以及接触面积、髌股关节反作用力和髌股关节压力的模型输出，并使用配对 t 检验比较峰值值，并计算标准化均数差值。
与穿鞋跑步相比，赤脚跑步可使髌股关节的峰值压力降低 12%（p=0.000）。赤脚跑步时，髌股关节压力的降低是由于髌股关节反作用力降低（12%，p=0.000）所致。
穿鞋跑步时髌股关节压力升高可能导致髌股疼痛。赤脚跑步可降低髌股关节的压力。
