Gait Analysis

Definition

Gait analysis is the systematic study of human and animal locomotion, focusing on how they walk or run. This analysis involves measuring various parameters, including stride length, speed, and body mechanics, to understand movement patterns and identify any abnormalities or inefficiencies. It plays a crucial role in the study of bipedal, quadrupedal, and multi-legged systems, as it helps researchers improve robotic locomotion by mimicking biological movement.
