Patients that leave intensive care for intermediate care present compromised muscle strength and functionality. In this context, our main objective was to describe the correlation between functional independence and handgrip strength in adult patients at intermediate care unit (IMCU). This was an analytical, correlational, and prospective study that compared patients admitted to IMCU after a stay of more than 24 hours in intensive care, with invasive or non-invasive ventilatory support. We used Barthel index (BI) and hand dynamometry at admission/discharge from IMCU. In total, 69 patients were included, 62.3% were men, with an average age of 63 years and a stay in intermediate care of five days. On admission to IMCU, 31.9% had complete dependence and 66.7% severe dependence. The most compromised categories were "bathroom use" and "stairs". On the other hand, "dressing" was the one with the greatest improvement (admission 24.6%, discharge 82.5%). A positive correlation [(r=0.4) and (p=0.000)] was identified between functionality and grip strength at admission and was maintained at discharge [(r=0.6) and (p=0.000)]. We identified a positive correlation between BI scores and handgrip strength, remaining stronger at IMCU discharge.
