Biomechanical Comparison of Human Walking Locomotion on Solid Ground and Sand

Kernkonzepte

This study compares human walking biomechanics on solid ground and sand, revealing significant differences in gait patterns and joint mechanics between the two terrains.

Zusammenfassung

This study explores how human walking differs on solid ground versus sand. It analyzes gait adaptations, joint mechanics, and ground reaction forces to provide insights into locomotion strategies on different terrains. The research highlights the importance of understanding biomechanical responses to varied surfaces for developing assistive devices and enhancing activity recognition systems.

The study collected data from 20 adults walking on solid ground and sand, focusing on kinematic and kinetic profiles. Results showed that walking on sand led to longer strides, wider steps, increased vertical variation in the center of mass, and faster walking speeds compared to solid ground. Joint angles differed significantly between terrains, with distinct adjustments observed in lower extremities during sand walking. Kinetic analysis revealed variations in ground reaction forces and joint moments between terrains.

The research contributes valuable insights into human locomotion adaptations on granular terrain like sand. By providing an experimental dataset for further biomechanical studies, this work enhances our understanding of gait mechanics across different environmental settings.
