The research on sports injury has long relied on traditional statistical methods, which often have obvious limitations when dealing with high-dimensional, nonlinear and multi-modal data. With the development of artificial intelligence technology, machine learning provides a new way to solve these complex problems. This paper systematically reviews the progress and application of machine learning in sports injury research. Firstly, the development of different machine learning methods in sports injury research was summarized. Secondly, we focus on five core applications of machine learning in the field of sports injury: data feature selection and dimensionality reduction, injury risk prediction, injury symptoms and signs classification, risk monitoring based on wearable devices, and imaging data analysis. Research shows that machine learning models show significant advantages in dealing with complex data patterns, improving prediction accuracy and achieving real-time dynamic intervention. However, research in related fields still faces challenges such as insufficient data quality and quantity, poor model interpretability, and barriers to multidisciplinary cooperation. Through the summary, it can be seen that future research in this field should focus on constructing standardized shared datasets, developing more interpretable models, and strengthening the cooperation and communication between multi-disciplines, and finally promoting the application of machine learning in sports injury prevention, diagnosis and rehabilitation.
Topical non-steroidal anti-inflammatory drugs (NSAIDs) are one of the commonly used drugs in the treatment of sports injury, but their standardized and rational use lacks evidence-based medical guidance. This guideline working group selected clinically important issues, fully collected the opinions of patients and clinical staff, and discussed them with the expert group. Based on the existing literature evidence, the "clinical practice guidelines for topical NSAIDs in the treatment of sports injury" was formulated following the methods and principles of international guidelines. In this guideline, 7 clinical concerns were finally selected, and a total of 22 recommendations were formed. Including the status, indications, contraindications, efficacy, combined application, use in special populations, adverse reactions, and countermeasures of topical NSAIDs in the treatment of sports injury. The purpose of this guideline is to provide evidence for orthopedics, sports medicine, rehabilitation medicine, sports science, and other practitioners in the treatment of sports injury, to promote the more standardized and rational use of topical NSAIDs.
