The equipment of the gait analysis system consists of a dynamic multi-dimensional force plate, pressure distribution, electronic track, physiological surface electromyography acquisition and analysis system, and kinematic three-dimensional image analysis system; the gait analysis system mainly A behavioral detection device used to detect the animal nerve center and guide the movement of the animal's limbs. When the animal moves in the gait movement area, the movement posture and the reaction of the limbs are collected through a computer to collect a series of data as a scientific research tool for the study of rehabilitation exercise. instrument.

Gait analysis system is mainly used to detect the animal nerve center and guide the movement of the animal's body and limbs. When the animal moves in the gait movement area, the movement posture, and A series of data on the reaction of the limbs are collected through the computer and used as a scientific research instrument for studying rehabilitation exercises.
The three-dimensional gait analysis system mainly consists of a three-dimensional motion capture system, a three-dimensional force plate, a wireless surface electromyograph, and plantar pressure. The three-dimensional gait analysis system collects the precise three-dimensional coordinates of each joint point of the human body during walking, the pressure between the sole of the foot and the supporting surface (vertical, left and right, and front and rear forces), and combines it with the EMG collected by the surface electromyography system The signal is processed through professional gait analysis software for three-dimensional reconstruction and model analysis to obtain the gait parameters of the human body during movement.
The role of gait analysis system
Human movement is the rhythmic contraction of more than 1,000 muscles controlled by the nervous system, driving more than 200 bones to move cooperatively around more than 100 joints result. Although life science research has made great progress in recent years, it is still far away from simulating the process of brain control of limb movements. Therefore, researchers in rehabilitation medicine and sports science generally use observation of macroscopic movements of human limbs to diagnose human motor function diseases and evaluate human body movements. Rehabilitation process, guide physical training and selection.
The gait analysis system is the most commonly used equipment for detecting macroscopic movements of human limbs. We mainly study the technology and devices for gait analysis through image processing of human movement images obtained by ordinary cameras. The content involves the detection and analysis technology of human body movement trajectory, ground branch reaction force and surface electromyography signal, as well as the method of assessment of rehabilitation process, etc.
Expand knowledge: Application conditions
Environments such as hospitals and sports training grounds are very different from laboratory environments. Therefore, For a gait analysis system to move from the research field to the application field (such as hospital clinical diagnosis), it must meet certain conditions:
1. Easy to operate: non-gait system research professionals, such as general doctors and nurses It can be used with a little training, and ideally anyone can operate it.
2. The output results are intuitive, easy to understand and save.
3. The execution time is faster to shorten the patient examination time (preferably no more than 5 minutes).
4. Can provide more parameters.
5. The cost is low and the operating expenses are also low.
6. It is more convenient to install, calibrate and transport.
7. Widely adaptable, suitable for measurements of walking, running and jumping from children to adults.
8. It requires sufficient measurement range and sensitivity, good linearity, less hysteresis effect, higher sampling rate, spatial resolution, pressure resolution and signal-to-noise ratio, etc. In addition, it also requires good repeatability. , stable performance.
9. There are fewer obstacles to the subject's movement and it is close to the natural movement state.
