Her muscle strength indicated ICU-acquired weakness, with a Medical Research Council sum-score (MRC-SS) of 40/60; still she continued with small but consistent improvements and started to participate actively in physical therapy sessions. She was encouraged to mobilize herself with exercises against gravity and was actively transferred to a chair each day with the help of 2 phys Do not include the following keywords: date, oxygenation, soeb, help
