Gait analysis is the study of animal locomotion, including locomotion of humans. Gait analysis is commonly used 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.
Gait analysis commonly involves the measurement of the movement of the body in space (kinematics) and the forces involved in producing these movements (kinetics).
