Can an Actigraph be Used to Predict Physical Function in Intensive Care Patients?

This study aims to investigate whether an actigraph, measuring in-hospital activity, used for a week after discharge from the ICU at Zealand University Hospital Køge, can predict physical function at three-month follow up. The hospital activity will be measured with actigraphy, a measurement tool that quantifies activity level. The activity will be measured for 7 days after ICU discharge. The actigraph is to be worn as a bracelet. The physical function will be measured with Chelsea Critical Care Physical Assessment Tool (CPAx). CPAx is assessed at ICU discharge and after three months.
