Summary

This study looks at how people with lower limb amputations naturally adjust their walking before going up or down slopes and stairs. Researchers will use machine learning to analyze these movement patterns. The goal is to create smarter prosthetic legs that can anticipate changes in terrain, making walking safer and easier. The study involves 70 participants, including both amputees and healthy volunteers.
