Title: Simplified Tai Chi for Reducing Fibromyalgia Pain
Brief Summary: Data from two recent Tai chi studies have found that Tai Chi yields symptomatic benefit in patients with fibromyalgia (FM). The purpose of this study is to confirm those findings in a larger randomized, controlled clinical trial in a community-based setting. We also sought to extend this line of inquiry by closely examining Tai chi's effect on physical function, specifically postural stability. Towards these ends, we conducted a single-blind, randomized controlled clinical trial of an FM modified 8-form Yang-style Tai chi program compared to standard education. Subjects in both conditions meet in small groups two times weekly for 60 minutes over 12 weeks.


Options:
A: Inclusion Criteria:

* Age greater than or equal to 18 years
* A diagnosis of fibromyalgia according to American College of Rheumatology criteria
* Moderate to severe pain, as defined by an average 7-day pain score of greater than 4.0 on an 11-point numerical rating scale for pain intensity
* Pain medications must have been stable for at least 14 days.
* Ability to follow the protocol (with reference to cognitive and situational conditions, (e.g. stable housing, ability to attend follow-up visits, motivation and commitment to self practice of CFQ Qigong for 45-60 minutes per day).
* Willing and able to give written informed consent

Exclusion Criteria:

* Presence of clinically significant medical disorder on history or physical exam that would compromise the participants' safety in the trial as judged by the study physician
* Already practicing CFQ Qigong on a regular basis
* Unable to commit to 45-60 minutes of CFQ Qigong practice per day
B: Inclusion Criteria:

* Subjects included adults over 40 years of age or older who met 1990 ACR criteria for the classification of FM. Those criteria include pain in three or more body quadrants (above the waist, below the waist, left of midline and right of midline) including axial pain by self-report for a minimum of three consecutive months.
* Additionally at least 11 of 18 muscle/tendon junction tender points were found to be painful via digital palpation of 4kg over 4 seconds by a trained examiner (Wolfe 1990).

Exclusion Criteria:

* Individuals were excluded if they practiced Tai chi within the past 6 months; - were exercising more than 30 minutes, three times weekly for past 3 months;
* could not independently ambulate without assistive devices;
* were unable to attain MD clearance for exercise within past 3 months;
* were unwilling to undergo random assignment; had cognitive impairment based on score \>3 Pfeiffer Mental Status;
* had significant depressive symptoms based on a score of \>27 on Beck Depression Inventory;
* had BPI pain severity scores less than 3/10, had planned elective surgery during the study period;
* were unwilling to keep all treatments/medications steady throughout the study period;
* were currently enrolled in another study.
C: Inclusion Criteria:

* Meets American College of Rheumatology (ACR) criteria for FM
* Inactive at study entry
* Willing to become more physically active
* Understands and willing to follow study recommendations regarding lifestyle modification
* Able to participate in the study for 2 years
* Agrees to not make any changes to current FM-related treatments

Exclusion Criteria:

* Any comorbidity that may worsen a participant's physical functioning, independent of FM (e.g., significant cardiovascular disease, history of arrhythmias, morbid obesity, autoimmune diseases, uncontrolled or untreated hypertension, significant renal or prostate disease, stroke, seizure disorder, any other significant neurological diseases)
* Significant peripheral neuropathy
* Any current psychiatric disorder that involves a history of psychosis, including schizophrenia, schizoaffective disorder, schizophreniform disorder, delusional disorder, bipolar disorder, or severe personality disorder. Participants with mood disorder are not excluded.
* Alcohol or substance abuse within the 2 years prior to study entry
* Current suicide risk or suicide attempt within the 2 years prior to study entry
* Severe physical disability that may interfere with physical activity
* Currently participates in structured exercise or plans to participate in an exercise program
* Any investigational medications or devices within 4 weeks prior to study entry
* Any expected life change, such as relocation, within the next 2 years that may prevent study participation
D: Inclusion Criteria:

* classification of fibromyalgia based on the criteria of the American College of Rheumatology
* female gender
* aged between 18 and 65 years

Exclusion Criteria:

* not having altered treatment in previous three years
* having signed a term of informed consent
* patients with other rheumatic diseases, painful osteoarticular conditions, uncontrolled cardiopulmonary disease, diseases of the lower limbs or uncontrolled diabetes were excluded
