Device and method for evaluating animal gaits

Abstract

The invention discloses a device and a method for evaluating animal gaits. The device comprises a driving gear and a driven gear, wherein the driving gear and the driven gear are connected through a conveying belt to form a transmission relation; the device further comprises a first winding cylinder which is installed on the driving gear and is coaxial with the driving gear, a walking cylinder which is installed on the driven gear and is coaxial with the driven gear, and gait recording paper. Wherein the gait recording paper is installed on the first winding drum in a winding drum mode, the free end of the gait recording paper is wound on the walking drum, and the free end of the gait recording paper extends out of the bottom of the animal walking drum. The device is simple and low in manufacturing cost, has no limitation on sites and evaluators, and can be used by simple training; moreover, the animal footprints on the gait recording paper are analyzed by the device, so that objective recording and quantification of gait parameters can be obtained in detail, and the marching gait of the animal can be evaluated.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and in particular relates to a device and method for evaluating animal gait. Background technique [0002] Gait analysis (gait analysis) is an inspection method to study walking regularity. It aims to reveal the key links and influencing factors of abnormal gait by means of biomechanics and kinematics, so as to guide rehabilitation evaluation and treatment. The parameters of gait analysis include the following categories: gait cycle parameters (such as support terms and swing terms), kinematic parameters (such as time parameters, distance parameters, time-space parameters), dynamic parameters (such as ground reaction force, moment , body center acceleration, lower limb muscle activity during walking), EMG activity parameters and energy parameters (such as energy metabolism parameters, mechanical energy parameters, oxygen valence), etc. At present, gait analysis is mostly used in h...

Problems solved by technology

First of all, the subjects of the current mainstream gait assessment tools are all human beings, which require the active cooperation of the subjects, and the lack of gait assessment tools for animals makes it difficult to carry out animal research on gait analysis; Tools for assessing the progress of animals, which can accurately record and form objective data, are expensive, while low-priced or laboratory-made assessment tools are not objective enough and the available data is very single and limited
