In order to better reduce sports injury, a method based on functional motion biological image data is proposed. Through performing functional motion screening test on wushu athletes, including 7 items of test, each athlete is given a score according to the test standard. This paper summarizes the mistakes and deficiencies of common movement patterns of athletes and makes different intervention plans to improve the effect of sports injury screening. The results show that, at P > 0.001 , there was a significant difference, and the experimental group FMS total score (15.02 ± 3.7) was lower than the control group FMS total score (18.51 ± 1.45). The recognition rate of the system is higher than that of the system based on single feature, and the recognition performance is better than that of the standard SVM and KNN recognition methods. It is proved that the design of the system is feasible, reliable, and effective.

Introduction Discuss the application of magnetic resonance imaging in evaluating ankle motion injury. Objective Verify the influencing factors of magnetic resource imaging (MRI) diagnosis based on the linear regression algorithm model. Methods The experimental group was diagnosed by MRI, while the control group was diagnosed by plain X-ray. After that, the mathematical model of the linear regression algorithm was constructed. Results It could be concluded that the MRI detection rate was 85.71%, and the X-ray plain film detection rate was 77.14%. The linear regression model analysis showed that the P-value of cartilage injury, tendon fracture, bone contusion, and soft tissue swelling was greater than 0.05. Conclusions MRI has more advantages in the application of ankle joint diagnosis. And ligament injury and joint effusion are the influencing factors of MRI diagnosis, which can highly indicate the authenticity of the injury in the ankle joint. Level of evidence II; Therapeutic studies - investigation of treatment results.

In order to improve the teaching effect of sports dance, this paper analyzes the traditional dance teaching motion capture, uses sensor motion perception algorithms to capture sports dance motion perception, and designs an intelligent sensor system that can be used for sports dance motion capture. Moreover, this paper combines the digital filter algorithm to design the hardware system structure of the sports dance motion capture system and builds a motion capture system for sports dance teaching based on the digital filter algorithm according to actual needs. In addition, this paper combines the simulation test to evaluate the performance of the system designed in this paper. The research results show that the motion capture system for sports dance teaching based on the digital filtering algorithm proposed in this paper can play an important role in sports dance teaching and effectively improve the efficiency of sports dance teaching.

Background: We aimed to assess the effect of life-cycle management on the satisfaction and health outcomes of children with chronic diseases and their parents, as well as the career benefits of healthcare workers. Methods: Participants were children with chronic diseases who received long-term treatment at the Three Gorges Hospital Affiliated to Chongqing University from January 2021 to November 2022. From the first admission, compare the children's disease onset, satisfaction and professional benefits of medical staff among "Medical and Nursing Integration" + "Internet plus"-based life cycle management group (n = 221, the experimental group), the routine management group (n = 53, the control group 1) and the "Medical and Nursing Integration" group (n = 67, control group 2). Results: The overall satisfaction of children in the experimental group (100 %) was higher than that in the control group 1 (98.11%) and control group 2 (98.51%). The times of second admission and third admission of patients in the experimental group were significantly lower than those in control group 1 were (both P<0.001) and control group 2 (both P<0.01). Nurses' sense of professional benefit, professional identity, and doctor's satisfaction with nurses in the experimental group were significantly higher than those in control group 1 (P<0.05, P<0.01, P<0.001) and control group 2 (all P<0.05). Conclusion: The application of "Medical and Nursing Integration" + "Internet plus"-based life cycle management in chronic disease nursing management can effectively improve the management on pediatric chronic diseases.
