Gait analysis system aiming at small animals

Abstract

The invention provides a gait analysis system aiming at small animals (such as mice, cats, chickens, and the like). The gait analysis system comprises a positioning and pressure measuring device, a three-dimensional force measuring device, a track device, a signal processing part and a data analysis and display part, wherein the positioning and pressure measuring device is used for collecting footmarks and contact pressures of a test object in real time; the three-dimensional force measuring device is used for measuring parameters of three-dimensional force, and the like of the test object in still and walking processes; the track device is used for inducing and controlling creeping actions of the test object; the signal processing part is used for carrying out amplification, filtering, analog digital conversion, and the like on caught original signals; and the data analysis and display part is used for further calculating gait parameters of step lengths, step frequencies, center-of-gravity shifts, and the like according to measured data and displaying results. The gait analysis system can quantitatively evaluate the gait of the test object, comprising the gait parameters of the step frequencies, the step lengths, distances among limbs, the pressure, the center-of-gravity shift, and the like, and can measure the gait parameters of the test object in a state of a slope or touchdown only by posterior limbs through the preset track.

Description

Technical field [0001] The invention relates to the field of motor function and rehabilitation testing, and more specifically to a system capable of accurately measuring and analyzing the gait characteristics of small animals (such as rats, cats, chickens, etc.). Background technique [0002] Gait refers to the coordinated relationship of limbs / components in time and space during the movement of people, animals or machines. It is an important parameter of kinematics and behavioral analysis. Gait analysis is a research method that uses the concepts, methods, and methods of biomechanics and known knowledge of anatomy and physiology to analyze the functional state of walking with the help of modern computer technology and graphic image technology. [0003] The human body's gait analysis has a wide range of applications. For example, after a patient's nerve injury or motor system injury, it can be repaired or compensated by a variety of methods, but the effect of the recovery is often ...

Problems solved by technology

[0006] Rat gait analysis devices are widely used in the mechanism, prevention, and treatment of neurosis, cerebral palsy, diabetes, arthritis and other diseases, and can meet the testing of new diagnosis and treatment methods and new drugs for motor nervous system injuries and diseases. Aiming at the shortcomings of the above-mentioned current rat gait analysis devices, such as incomplete measurement parameters, complicated measurement devices, and cumbersome measurement methods, the present invention provides a system for measuring the gait characteristics of small animals, especially rats, which can realize the measurement of small animals. Quantitative evaluation of multiple gait parameters of animals (such as mice, cats, chickens, etc.), including step length, step frequency, step sequence, distance between limbs, pressure, center of gravity offset, etc. The crawling behavior of rats is induced and controlled, and the gait parameters of rats are measured on slopes or in the state of pure hindlimb landing, which reduces the cost and equipment space while ensuring accuracy
