Muscle strength and mobility of individuals with COVID-19 compared with non-COVID-19 in intensive care.

Background: Critical illness may affect muscle strength and mobility.

Objectives: To compare muscle strength, mobility, and in intensive care unit (ICU)-acquired weakness (ICUAW) prevalence among individuals with COVID-19 and other critical illnesses; to identify factors associated with muscle strength, mobility, and length of stay in COVID-19; and to determine the Perme Intensive Care Unit Mobility Score (PICUMS) cut-off point for ICUAW.

Methods: We included individuals aged ≥18 in ICU who require mechanical ventilation.
