Objective:
The objective of this scoping review is threefold: (1) to describe outcomes of and determinants for physical functioning in pediatric intensive care unit (PICU) survivors evaluated during and/or after their PICU stay, (2) to provide an overview how physical functioning and its associated determinants in this population are reported, measured and classified in accordance with the International classification of Functioning, Disability and Health-Children and Youth framework (ICF-CY) components and (3) to synthesize key gaps in knowledge and research and clinical recommendations related to our review questions.

Introduction:
Optimal physical functioning in children is of major importance in their developmental trajectories and for the prevention and recovery of health problems across lifespan. PICU children are at high risk of poor physical functioning during and after critical illness. A recent overview of the literature, concerning evaluation of physical functioning in PICU survivors according to the ICF-CY components, is lacking.

Inclusion criteria:
This review includes empirical studies reporting outcomes and determinants of physical functioning in PICU survivors evaluated during and/or after PICU stay. All English language studies reporting empirical data will be included with no restrictions set on the types of study designs used.

Methods:
This review will be conducted in accordance with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) statement. To locate studies eligible for inclusion, the electronic databases Pubmed, EMBASE, CINAHL and Cochrane Library will be searched from the earliest records to October 2019. Study selection will be performed by two independent reviewers. Covidence software will be used to screen titles and abstracts as well as the full-text of included studies. Data extraction will be conducted using a customized form. The extracted data will be presented in diagrammatic or tabular form with an accompanying narrative summary.
