In June 2017 researchers from Norway published their review of the scientific literature to assess the effect of aerobic exercise in adults with fibromyalgia. A total of 13 studies involving 839 individuals were included in the review. Results showed that aerobic exercise probably improved health related quality of life. In addition, there was low-quality evidence to suggest that aerobic exercise may slightly decrease pain intensity and also slightly improve physical function. However, there appeared to be little evidence to show that aerobic exercise may lead to a difference in fatigue and stiffness.
