Fatigability in Osteoarthritis: Effects of an Activity Bout on Subsequent Symptoms and Activity

摘要

Background.Older adults with osteoarthritis (OA) are more likely to experience increased fatigue following bouts of physical activity than those without OA. The highly “fatigable” nature of this population is problematic as it has been linked to OA severity and decreased function. This study examined the effects of engaging in standardized lab-based physical tasks on subsequent fatigue, pain, and activity in older adults with OA.
