Abstract

Summary

Description: The Physical Function in ICU (intensive care unit) test (PFIT) is a composite measure of muscle strength and physical function that was developed by Australian physiotherapists from a sample of medical-surgical ICU and respiratory weaning unit patients.1 In 2013, the measure was refined to improve clinimetric properties by item reduction to four tasks (sit-to-stand, marching on the spot cadence, shoulder flexion and knee extension strength) and testing of a matrix for converting ordinal to interval scores, resulting in the present PFIT-scored (PFIT-s) version.2 The PFIT-s is accessible, takes approximately 10 to 15 minutes to administer,3 requires minimal equipment (a chair and stopwatch), is available in English and Brazilian Portuguese,4 and is extensively validated.5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15
