Patients coming from emergency department started a rehabilitative treatment during their hospitalization in ICU. Patients transferred from an external ICU started the rehabilitation in neurorehabilitation department. Aim of the study is to evaluate if an early rehabilitation, started since the acute stage of the damage, is able to reduce the decannulation time in this group of patients.
