[INTRODUCTION] There are 178 million elderly people and 200 million chronic patients in China. However, the number of rehabilitation therapists in China is relatively small and the level of clinical experience is imbalance. In addition, in clinical treatment, therapists' subjective judgment is the main method, and there is little objective evidence-based medicine. Therefore, based on the current situation, it is urgent to develop an objective and quantitative evaluation system that is easy to operate and standardized. The video motion capture dynamic assessment system is a video capture assessment system jointly developed by China rehabilitation research center, Peking University and SPINE GUARD Musculoskeletal Pain Exercise Rehabilitation Center with independent patent rights. This paper mainly introduces the composition and development of this evaluation system. [SUBJECTS AND METHODS] Video motion capture dynamic assessment system (hereinafter referred to as dynamic assessment system) is mainly composed of a host computer, a computer screen, three cameras and a 3-meter pressure runway. The three cameras of this dynamic evaluation system are respectively located at the front and the left and right sides, and mark points can be taken for the nose tip, shoulder, elbow, wrist, great rotor and so on. At least two markers were selected for each movement, such as neck flexion, and two markers of nasal tip — acromion were selected. The activities angle of the action accurate to 0.01 °, distance will be accurate to 0.01 mm. Moreover, the camera of this system has a feature that prompts patients with a mirror mode to minimize the external influence on patients' subjective consciousness. The operation steps are mainly divided into patient information collection, pressure runway test, SFMA evaluation. [RESULTS] This set of dynamic evaluation system can conveniently screen the following results: (1)It can quickly screen out body asymmetry and changes in body force lines;(2)It can accurately screen out the movement chain and weak chain that have the greatest impact on patients;(3)The deviation of the patient's center of gravity and the static and dynamic distribution of plantar pressure can be observed;These results can quickly lead to treatments. [DISCUSSION] The system has been developed and formulated the corresponding software system, is currently undergoing clinical testing. The whole test process only takes ten minutes, which can conveniently provide reliable, quantitative data analysis, help the therapist quickly find the patient's problems, and save the evaluation time. Therefore, the clinical application prospect of this evaluation system can be expected.
