• Abstract:

  Introduction: Intensive care units (ICUs) provide care for critically ill patients, who often remain immobilized for long periods, increasing the risk of complications such as muscle loss, reduced functionality, and ICU-acquired weakness. In this context, functional assessment and the use of tools such as the Perme Scale are essential for monitoring and early intervention. Objective: To analyze the functionality of critically ill patients and the applicability of the Perme Scale in intensive care units, as well as its relationship with clinical outcomes. Methods: This is an integrative literature review conducted in scientific databases (PubMed, SciELO, LILACS, and Google Scholar), including studies published between 2014 and 2025. Observational studies, reviews, and prospective studies addressing mobility, functionality, and the use of the Perme Scale in adult ICU patients were selected. Data analysis was performed descriptively and categorized into thematic areas. Results: The included studies demonstrated that the Perme Scale is a valid tool for assessing mobility in critically ill patients, with the potential to aid in predicting clinical outcomes such as length of hospital stay and functional recovery. Furthermore, early mobilization was associated with the preservation of functionality and a reduction in physical decline during hospitalization. However, differences in outcomes were identified among specific populations, and methodological limitations were noted in the analyzed studies. Conclusion: The Perme Scale is a relevant instrument for the functional assessment of critically ill patients, contributing to the monitoring of mobility in the ICU. Early mobilization demonstrates a positive impact on functional recovery, although further research is needed to standardize the evidence.
