Motor dysfunction seriously affects people’s quality of life, and currently is one of the main health problems facing mankind. Sports and rehabilitation biomechanics focuses on motor dysfunction, providing the theoretical basis for motor function assessment, dysfunction intervention technology and equipment development. In 2024, the biomechanical research of motor dysfunction achieved fruitful results. From 3 aspects, namely, non-contact assessment of motor function, intelligent classification and grading of dysfunction, and neurobiomechanical mechanism of motor dysfunction, this review summarizes the research progress in the past year and discusses the future development direction.
