This was a randomized, 52 week, single blind comparative effectiveness trial. Participants with fibromyalgia were randomly assigned to either supervised aerobic exercise twice weekly for 24 weeks or to one of four tai chi interventions: 12 or 24 weeks of supervised tai chi completed once or twice weekly. We followed participants for 52 weeks. The primary outcome was the change in revised fibromyalgia impact questionnaire (FIQR) total score from baseline to 24 weeks.
