Neuromuscular dysfunction is prevalent in critically ill patients, is associated with worse
short-term outcomes, and is a determinant of long-term disability in intensive care unit
survivors. Diagnosis is made with the help of clinical, electrophysiological, and
morphological observations; however, the lack of a consistent nomenclature remains a
barrier to research. We propose a simple framework for diagnosing and classifying
neuromuscular disorders acquired in critical illness.
