Fatigue experienced by people with cerebral palsy: a systematic review of assessment tools and decision tree

PurposeTo conduct a systematic review of self- and proxy-report fatigue assessment tools used in studies of people with cerebral palsy (CP) of all ages, and to develop a fatigue assessment tool decision tree for clinicians and researchers.Materials and methodsFive electronic databases (MEDLINE, PsycInfo, CINAHL, Web of Science and Cochrane) were searched to September 2021 to identify studies assessing self-reported fatigue in people with CP of any age. The assessment tools utilised were extracted and two reviewers appraised the tool characteristics, clinical utility and psychometric properties. A decision tree for selecting fatigue assessment tools was constructed.ResultsTen assessment tools were identified across thirty-nine studies, three of which are valid and reliable for assessing fatigue severity and impact in people with CP. A four-level fatigue assessment tool decision tree was constructed. No valid and reliable tool for assessing cognitive fatigue was identified; responsiveness has not been evaluated in any tool for people with CP.ConclusionsPhysical fatigue screening and assessment tools for people with CP are available and are presented in our decision tree, however their utility as outcome measures remains unclear. Cognitive fatigue is understudied and poorly understood, further work is required in this area.
