Background
Gait refers to the coordination of the components of the limbs in time and space during the movement of a human, an animal or a machine, and is an important parameter for the analysis of kinematics and behaviours. Gait analysis is a research method for analyzing the functional state of walking by means of modern computer technology and graphic image technology by utilizing the concept, method and means of biomechanics and known anatomical and physiological knowledge. The gait analysis of human body has a wide application range, such as after the nerve injury or the motor system injury of a patient, the rehabilitation or compensation can be carried out by various means, but how the effect is after the recovery is, the gait analysis of the patient is often used for evaluating. Generally, the new repair or compensation techniques must be tested or verified by animal experiments before they are used clinically, and the specific drugs for treating arthritis and other diseases must be tested by animal experiments. Therefore, the gait analysis of the animals has important practical significance, can evaluate the behavioral ability, the motor function and the cognitive ability of the animals, and has important significance for researching the mechanism, preventing and treating diseases such as neurosis, cerebral palsy, diabetes and the like. Animal gait analysis systems have become important devices for developing relevant scientific research.
