The diseases that lead to abnormal movement of patients are mainly divided into five categories: deformity, muscle weakness, sensory loss, pain and impaired motor control. There are many reasons for these diseases, such as joint contracture and congenital clubfoot, which will lead to deformity. Monitoring and quantitatively recording the abnormal gait behavior of these diseases is of great significance for confirming the specific situation of patients and formulating treatment methods.
Three-dimensional gait analysis system includes a series of advanced equipment, such as infrared optical motion capture system, surface electromyography, dynamometer, wearable metabolic monitoring system and so on. It can accurately obtain a series of physical behavior parameters of the subjects, which is of great significance in the field of gait analysis.
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.
