[Research Progress of ICU-acquired Weakness].

ICU-acquired weakness (ICU-AW) is a common complication in the intensive care unit (ICU). The occurrence of ICU-AW directly leads to prolonged ICU stays for critically ill patients, and in severe cases, it continues to affect their quality of life even after discharge. This article provides a comprehensive review of the research progress on ICU-AW based on domestic and foreign studies, aiming to provide a scientific overview of ICU-AW, including its definition, pathophysiology, diagnosis, screening tools, influencing factors, and potential intervention strategies, so as to promote timely planning and implementation of relevant screening and intervention measures.
