[Research progress in diagnosis and evaluation of intensive care unit-acquired weakness]

Intensive care unit-acquired weakness (ICU-AW) is a common and serious complication in intensive care unit (ICU) with a high incidence of typical systemic and symmetrical muscle weakness, which mainly involves the limbs (proximal more than distal) and respiratory muscles, and can affect the short-term and long-term outcomes among ICU patients, further reduces their quality of life, and seriously delays their return to family and society. At present, the etiology and pathogenesis of ICU-AW are not clear, and the diagnosis methods are different. There is no "gold standard" for the diagnosis of ICU-AW, and there are still great difficulties in early diagnosis or recognition. This paper reviews the progress of ICU-AW diagnosis and evaluation, aiming to provide a reference for clinical practice and scientific research.
