Fatigue in XXXX : an integrative review.

@entity1 @entity3777 @entity1295 @entity191 @entity2727
Fatigue, one of the most prevalent and underassessed nonmotor symptoms in @entity1 with @entity191 ( @entity191 ), is reported to be a major cause of disability and reduced quality of life. The purpose of this review was to systematically examine the scientific literature and report how @entity1295 is defined and measured and what interventions are used to treat it. A synthesis of the current literature will expose the current state of the science of @entity1295 in @entity191 , propose areas for future research, and offer practice implications. An integrative review of the literature was conducted. The electronic databases CINAHL, Psychinfo, and PUBMED were searched using the keywords " @entity3777 ," "measurement," "interventions," "treatment," and " @entity2727 ." One hundred fourteen articles were found. Nineteen studies met review criteria. No universal definition of @entity1295 in @entity191 was found, making it difficult to measure. However, central, physical, mental, and peripheral fatigues were described. Six scales were found that measure @entity1295 in @entity191 ; only one specific to @entity191 , the Parkinson Fatigue Scale, measured physical @entity1295 . Seven studies reported interventions to treat @entity1295 and were categorized as medication, exercise, and alternative interventions. None of these interventions had a significant effect on @entity1295 . Findings showed that (a) there is a lack of a universally accepted definition of @entity1295 because of its subjective nature, (b) existing @entity1295 measurement tools do not measure all types of @entity1295 in @entity191 , and (c) no intervention had a significant effect on @entity1295 . There is a need to define and explore @entity1295 further using qualitative methods. Further development of instruments to measure @entity1295 in @entity1 , younger onset, and older adults with @entity191 is needed. A focus on @entity1 -centered interventions to reduce @entity1295 in @entity1 with @entity191 is a research priority.
