Gu Y, Mei Q, Fernandez J, Li J, Ren X, Feng N - PLoS ONE (2015)

Bottom Line: The center of pressure displacement velocity of bound feet was also greatly reduced with the shortening of trajectories.This suggests that the proprioceptive system adjusts motor function to adapt to new loading patterns while maintaining locomotive stability.A biomechanical understanding of bound feet may assist with prevention, treatment and rehabilitation of bound feet disorders.

ABSTRACT
The custom of bound feet among Chinese women has existed for almost a century. This practice has influenced the daily life of Chinese women, especially during everyday locomotion. The primary aim of this study is to analyze the loading patterns of bound feet. Specifically, the plantar pressure and center of pressure were analyzed for peak pressure, contact area, force time integral, center of pressure displacement velocity and trajectory in the anterior-posterior direction via a comparison with normal feet. The key outcomes from this work were that the forefoot and rearfoot of bound feet bear the whole loading during stance phase. The center of pressure displacement velocity of bound feet was also greatly reduced with the shortening of trajectories. This suggests that the proprioceptive system adjusts motor function to adapt to new loading patterns while maintaining locomotive stability. A biomechanical understanding of bound feet may assist with prevention, treatment and rehabilitation of bound feet disorders.

Mentions: Fig 3-A shows the peak pressure of four anatomical parts (medial and lateral of the rear and forefoot). There is a significant difference between bound and normal feet, with p = 0.000<0.05 of the medial forefoot, p = 0.000<0.05 of the lateral forefoot, p = 0.000<0.05 of the medial rearfoot and p = 0.000<0.05 of the lateral rearfoot.
