This is a pilot randomized controlled trial of Tai Chi for fibromyalgia. We plan to enroll 60 patients with fibromyalgia over a two year period. Participants are randomized to either a Tai Chi program or an attention control intervention. Assessments are performed at baseline, week 12 and week 24. This study will provide preliminary data on the potential acceptability and safety of Tai Chi for FM and will help guide the design of a future large-scale study of the efficacy of this alternative therapy.
