Understanding the form and function in Chinese bound foot from last-generation cases

Area of Science:

• Biomechanics
• Anthropology
• Paleopathology

Background:

• The biomechanics of typically developed feet are well-documented.
• The Chinese bound foot, an extinct cultural practice, represents a unique model of atypical foot development and adaptation.

Purpose of the Study:

• To investigate the morphological and functional adaptations of the Chinese bound foot.
• To analyze gait, bone density, and joint changes resulting from foot binding.

Main Methods:

• Statistical shape modeling for foot morphology and posture analysis.
• Gait analysis to assess plantar loading distribution.
• Finite element simulation and bone remodeling prediction for bone density adaptation.

Main Results:

• Bound feet showed increased arch height, vertical calcaneus, and altered metatarsal size compared to typical feet.
• Altered foot structure shifted load transfer through the tibia, talus, and calcaneus, reducing medial-lateral motion.
• Increased bone density and stress were observed at the talus-calcaneus articulation, with enhanced bone growth in related joints.

Conclusions:

• Foot binding significantly reshaped foot structure and altered biomechanical loading patterns.
• The study provides insights into bone resorption and adaptation mechanisms under unique mechanical stresses.
• Understanding these adaptations can inform studies on bone remodeling in response to diverse loading environments.
