The equipment of gait analysis system mainly consists of multi-dimensional force measuring table, pressure distribution, and electronic runway for dynamics; surface electromyography acquisition and analysis system for physiology; and three-dimensional image analysis system for kinematics.
Mainly used in ergonomics, biomechanics, rehabilitation medicine, sports medicine, physiology, clinical rehabilitation, muscle/movement analysis, gait analysis, bio-engineering, animation, game production, three-dimensional dynamics and other fields, the industry outlook is promising.
Gait analysis system, mainly used to detect the animal nerve center, to guide the animal body limbs movement behavior detection device, the animal in the gait movement of the region on the movement of the movement posture, and limbs response situation, through the computer to collect a series of data, as a research instrument for the study of the rehabilitation of movement.
The three-dimensional gait analysis system is mainly composed of three-dimensional motion capture system, three-dimensional force measurement platform, wireless surface electromyography, plantar pressure. The three-dimensional gait analysis system collects the precise three-dimensional coordinates of each joint point of the human body in the process of walking.
The pressure between the plantar foot and the supporting surface (vertical, left-right, front-back three directions of force), and combined with the EMG signals collected by the surface electromyography system, through the professional gait analysis software for three-dimensional reconstruction and modeling analysis, so as to get the human body's gait parameters during movement.
Application conditions of gait analysis system
The environment of hospitals, sports training grounds and other environments is very different from the laboratory environment, therefore, a set of gait analysis system from the research field into the application field (such as clinical diagnosis in hospitals), must have certain conditions:
1. Easy to operate: non-gait system research Professionals, such as general doctors, nurses with a little training will also be used, ideally anyone can operate.
2, the output results are intuitive, easy to understand and save.
3. Faster execution time to shorten the examination time (ideally no more than 5 minutes).
4, can provide more parameters.
5. Lower cost and running expenses.
6, easier to install, calibrate and transport.
7, a wide range of adaptability, suitable for children to adults from walking, fast running and jumping and other measurements.
8, the requirements of adequate measurement range and sensitivity, good linearity, less hysteresis effect, higher sampling rate, spatial resolution, pressure resolution and signal-to-noise ratio, in addition to the requirements of good repeatability, stable performance.
9, less obstacles to the action of the subject, close to the natural state of motion.
