Adults with osteoarthritis (OA) experience fatigue in daily life that
is negatively related to physical activity; however, it is unclear how task
demands affect fatigue and occupational performance. We examined effects of a
cognitive task on subsequent symptoms and activity. METHOD: Adults with knee or
hip OA completed a standardized cognitive task during a lab visit. Objective
physical activity and symptoms were tracked during two home-monitoring periods
(i.e., 4-day period before and 5-day period after the lab visit). Multilevel
modeling was used to compare pretask with posttask fatigue, pain, and activity
levels. RESULTS: Fatigue increased and pain decreased for 2 days after performing
the lab task. The authors found no pretask to posttask changes in activity
levels. At posttask, daily fatigue and activity patterns changed relative to
baseline. CONCLUSION: For adults with symptomatic OA, cognitive task demands may
be an important contributor to fatigue and pain.
