is the systematic study of animal locomotion
, ( more specific as a study of human walking) 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 asses, plan and treate individuals with conditions affecting their ability to walk. It is also commonly used in sports such as athletics to help athletes run more efficiently and to identify posture-related or movement-related problems in people with injuries.
The study encompasses quantification
, i.e., introduction and analysis of measurable parameters of gaits
, as well as interpretation, i.e., drawing various conclusions about the animal (health, age, size, weight, speed, etc.) from its gait.
