What is a gait analysis training system?

According to the biomechanical principle, the three-dimensional gait analysis system detects and records the data of trunk and joint movement, muscle activity, ground stress, joint moment and work, plantar pressure distribution and oxygen consumption during walking, and compares them with the normal reference range to determine the abnormal key image factors and compensatory changes, thus providing suggestions and references for clinical diagnosis, clinical decision-making and treatment effect evaluation. Three-dimensional gait analysis system includes infrared optical motion capture system, surface electromyography, dynamometer, wearable metabolic monitoring system and a series of advanced equipment. , which can accurately obtain a series of physical parameters of the subjects, is of great significance in the field of gait analysis.

Three-dimensional gait analysis system

Optical three-dimensional motion capture system: the core equipment for measuring patients' gait, which realizes non-invasive and continuous dynamic measurement by monitoring and tracking the position of specific reflection marker points on the target, thus completing the motion capture task in gait analysis and obtaining kinematics data.

Three-dimensional dynamometer: In the gait process, there is a stage called support stage. At this stage, limb bearing will produce significant forces in three directions on the ground, namely, vertical, front and back, inside and outside. When the body changes its position by supporting the lower limbs, the magnitude and direction of these forces will also change. The ground reaction force, torque and power data at this stage can be effectively obtained by three-dimensional dynamometer. The analysis of these data is helpful to understand the mechanism of gait and obtain the accurate mechanical parameters of abnormal gait.

Surface electromyography (SEMG) analysis system: SEMG analysis system determines the period and relative intensity of muscle function by obtaining the electrical signals of muscles, and judges the gait abnormality caused by the change of muscle activity duration and exercise intensity, which is conducive to making a more accurate judgment on the causes of gait abnormality.

In addition to the above three kinds of equipment, some gait laboratories will also be equipped with foot pressure distribution and exercise cardiopulmonary tester to provide more comprehensive information for gait analysis.
