Background: Longer duration of hospitalization and mechanical ventilation contribute to the development of Intensive Care Unit acquired weakness (ICUAW). This condition promotes impairments in cardiovascular and respiratory systems that contributes to the decline of physical and functional status of survivors. Aim: to evaluate muscle strength and functional status of ICU patients and to correlate these measures and length of stay. Methods: 70 critical patients, (54.3% males), mean age of 63.1±8.9 years and length of stay at ICU of 5.4±3 days of admitted in ICU were evaluated through the manual score of muscular strength by Medical Research Council (MRC) and functional status by Functional Status Score (FSS-ICU), Physical Function ICU Test (PFIT) and Functional Independence Measure (FIM-motor domain). Statistical significance was set at p Results: from the total 52.8% and 47.2% presented diagnosis of heart and respiratory diseases, respectively; 27% presented peripheral muscle weakness, MRC Conclusion: Prolonged immobility during hospitalization results in loss of muscle strength and functional capacity. There is positive correlation between muscular strength and functional status, considering FSS-ICU, PFIT and FIM scales. The longer length of stay in ICU, the greater the loss of functional capacity in critical patients. |
