Application of Surface Electromyography in Knee Joint Sports Injury Rehabilitation

Abstract

Knee joint sports injuries are common and significantly impact patients' daily activities and athletic abilities. Effective rehabilitation methods are crucial for restoring knee joint function. Surface electromyography (sEMG), a technology for monitoring muscle activity, has seen widespread use in rehabilitation medicine in recent years. This study aims to explore the application of sEMG in knee joint sports injury rehabilitation, particularly its role in rehabilitation assessment, training effect monitoring, and the development of personalized rehabilitation plans. By reviewing the basic principles of sEMG and its signal characteristics and combining them with the rehabilitation goals and strategies for knee joint injuries, this paper analyzes practical applications and outcomes of sEMG in rehabilitation. The study indicates that sEMG can effectively evaluate knee joint function and muscle activity, monitor rehabilitation training in real-time, and support the creation of personalized rehabilitation plans. Case studies demonstrate sEMG's significant advantages in optimizing the rehabilitation process and enhancing treatment efficacy. However, challenges such as signal noise and equipment cost remain, necessitating further research and technological improvements to advance the application and development of sEMG in rehabilitation medicine.
