Problems solved by technology
Although the movement of the limbs can reflect the activity of the participating muscle groups to a certain extent, it cannot accurately reflect the degree of muscle participation of the animal
The marker itself may affect the trajectory of the limbs, and its sensitivity needs to be improved
As a result, the existing experimental devices for animal gait measurement have a single analysis method and cannot perform animal gait analysis well.

The invention discloses an experimental device and experimental method for measuring animal gait characteristics, the experimental device comprises a running machine, a behavior box, a pressure sensor and a shooting device, the running machine is provided with a running track, the behavior box covers the running track, the behavior box and the running track define an experimental cavity, the experimental cavity is used for bearing an experimental animal, the pressure sensor is arranged on the running track and is used for measuring the stress of four limbs of the experimental animal, and the shooting device is arranged towards the running machine and is used for shooting the motion posture of the experimental animal. According to the experimental device for measuring the animal gait characteristics, the stress information of the four limbs of the experimental animal can be collected while the motion behavior video information of the experimental animal is collected, multi-dimensional experimental animal gait analysis is achieved, and therefore the objectivity of experimental animal motion analysis is improved.
Description
technical field [0001] The invention relates to the technical field of animal experiment equipment, in particular to an experimental device and an experimental method for measuring animal gait characteristics. Background technique [0002] Gait feature analysis is very important for the research and treatment of motor system diseases such as Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, joint disease, etc. Gait feature detection is often used in human cases, and it is especially suitable for animals However, there are few methods for analyzing the relevant gait characteristics of large animals, and there are great limitations. For the detection device of large animals, the camera is generally used to record the movement trajectory of the limbs, and the function of the movement is evaluated by analyzing the posture and motion dynamics of the limbs, joints and ankles. track. Although limb movement can reflect the activity of the participating musc...
