Obesity causes increased loading on the foot which can damage the soft tissue and bone ultimately leading to foot problems. Experimental and computational methods were used to analyse the chain of biomechanical changes in the lower limb due to obesity. The experimental study shows some changes in foot posture and gait where obese subjects were more likely to have pronated feet, smaller joint angles in the sagittal and frontal planes, smaller cadence, and smaller stride length. Anatomically correct finite element models generated on obese subjects showed increased and altered internal and plantar stress. Altered foot posture was identified as a key indicator of increased internal stress indicating the importance of foot posture correction.
肥胖会导致足部承受的负荷增加，这可能会损害软组织和骨骼，最终导致足部问题。实验和计算方法被用于分析肥胖导致的下肢生物力学变化链。实验研究表明，肥胖受试者的足部姿势和步态存在一些变化，他们更有可能出现扁平足，矢状面和额状面的关节角度更小，步频更小，步幅更小。在肥胖受试者身上生成的解剖学正确的有限元模型显示，内部应力和足底应力增加且发生了改变。足部姿势改变被确定为内部应力增加的关键指标，这表明了矫正足部姿势的重要性。
