OBJECTIVE: To investigate the associations between perceived physical function
(self-report) and physical and cognitive performance (objective assessments) in
persons with fibromyalgia (FM). DESIGN: Correlational study. SETTING: Exercise
testing laboratory in Southern California. PARTICIPANTS: Community-residing
ambulatory adults meeting the American College of Rheumatology 1990 criteria for
FM (N=68; mean age, 59.5y). INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES:
Composite Physical Function scale, Senior Fitness Test (3 items), Fullerton
Advanced Balance scale, 30-foot walk, Trail Making Test parts A and B, Digit
Symbol Substitution Test, a composite score of these 3 cognitive measures,
attention/executive function composite, processing speed composite, problem
solving, inhibition, and episodic memory composite. RESULTS: Hierarchical
regression analyses showed that after controlling for age and FM symptoms, better
physical performance (based on assessments, not self-report) was associated with
higher cognitive function in attention/executive function, processing speed,
problem solving, and inhibition. CONCLUSIONS: Researchers should continue to
investigate the relationship between physical and cognitive function in both
clinical and nonclinical populations, as well as explore changes across time.
Because physical activity has been associated with neural improvements, further
research may identify whether particular mechanisms, such as neurogenesis,
synaptogenesis, or changes in inflammatory marker levels, are involved.
