Gait analysis

Definition

Gait analysis is the systematic study of human and animal locomotion, focusing on the mechanics of walking or running. This analysis involves measuring various parameters such as speed, stride length, and joint angles to understand movement patterns, which is crucial in fields like robotics for designing legged locomotion systems that mimic biological movement.
