Gait analysis is the systematic study of
animal locomotion, more specifically the study of human motion, using the eye and the brain of observers, augmented by
instrumentation for measuring body movements,
body mechanics, and the activity of the muscles. Gait analysis is used to assess, plan, and treat individuals with conditions affecting their ability to walk. It is also commonly used in
sports biomechanics to help athletes run more efficiently and to identify posture-related or movement-related problems in people with injuries.
