There were no statistically significant differences in attrition rates between the interventions .
In general , adverse effects were poorly recorded , but no serious adverse effects were reported .
The evidence ( rated as low quality ) suggested that moderate- and moderate- to high-intensity resistance training improves multidimensional function , pain , tenderness , and muscle strength in women with fibromyalgia .
The evidence ( rated as low quality ) also suggested that eight weeks of aerobic exercise was superior to moderate-intensity resistance training for improving pain in women with fibromyalgia .
There was low- quality evidence that 12 weeks of low-intensity resistance training was superior to flexibility exercise training in women with fibromyalgia for improvements in pain and multidimensional function .
There was low- quality evidence that women with fibromyalgia can safely perform moderate- to high-resistance training
BACKGROUND Fibromyalgia is characterized by chronic widespread pain that leads to reduced physical function .
Exercise training is commonly recommended as a treatment for management of symptoms .
We examined the literature on resistance training for individuals with fibromyalgia .
Resistance training is exercise performed against a progressive resistance with the intention of improving muscle strength , muscle endurance , muscle power , or a combination of these .
OBJECTIVES To evaluate the benefits and harms of resistance exercise training in adults with fibromyalgia .
We compared resistance training versus control and versus other types of exercise training .
A randomized trial of tai chi for fibromyalgia.
BACKGROUND Previous research has suggested that tai chi offers a therapeutic benefit in patients with fibromyalgia . METHODS We conducted a single-blind , r and omized trial of classic Yang-style tai chi as compared with a control intervention consisting of wellness education and stretching for the treatment of fibromyalgia ( defined by American College of Rheumatology 1990 criteria ) . Sessions lasted 60 minutes each and took place twice a week for 12 weeks for each of the study groups . The primary end point was a change in the Fibromyalgia Impact Question naire ( FIQ ) score ( ranging from 0 to 100 , with higher scores indicating more severe symptoms ) at the end of 12 weeks . Secondary end points included summary scores on the physical and mental components of the Medical Outcomes Study 36-Item Short-Form Health Survey ( SF-36 ) . All assessment s were repeated at 24 weeks to test the durability of the response . RESULTS Of the 66 r and omly assigned patients , the 33 in the tai chi group had clinical ly important improvements in the FIQ total score and quality of life . Mean ( + /-SD ) baseline and 12-week FIQ scores for the tai chi group were 62.9+/-15.5 and 35.1+/-18.8 , respectively , versus 68.0+/-11 and 58.6+/-17.6 , respectively , for the control group ( change from baseline in the tai chi group vs. change from baseline in the control group , -18.4 points ; P<0.001 ) . The corresponding SF-36 physical-component scores were 28.5+/-8.4 and 37.0+/-10.5 for the tai chi group versus 28.0+/-7.8 and 29.4+/-7.4 for the control group ( between-group difference , 7.1 points ; P=0.001 ) , and the mental-component scores were 42.6+/-12.2 and 50.3+/-10.2 for the tai chi group versus 37.8+/-10.5 and 39.4+/-11.9 for the control group ( between-group difference , 6.1 points ; P=0.03 ) . Improvements were maintained at 24 weeks ( between-group difference in the FIQ score , -18.3 points ; P<0.001 ) . No adverse events were observed . CONCLUSIONS Tai chi may be a useful treatment for  fibromyalgia  and merits long-term study in larger study population s.
