International Classification of Functioning, Disability, and Health Domains of 60 Physical Functioning Measurement Instruments Used During the Adult Intensive Care Unit Stay: A Scoping Review.

Background: There has been a recent surge in the creation and adaptation of instruments to measure physical functioning (PF) in the intensive care unit (ICU). Selecting the right measurement instrument depends on understanding the core constructs that it measures in terms of the International Classification of Functioning, Disability and Health (ICF) domains.

Purpose: The purpose of this study was to map systematically the ICF domains and subdomains included in the PF measurement instruments used for adult patients during the ICU stay.
