Human Gait Analysis

Definition

Human gait analysis is the systematic study of human walking patterns to understand the mechanics, efficiency, and characteristics of movement. This analysis involves capturing data through various methods such as video recording, motion capture systems, and force plates, helping to assess bipedal locomotion, identify abnormalities, and inform rehabilitation practices. By examining the intricate dynamics of walking, researchers can also draw parallels to the design and development of legged robotic systems.
