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 .
Content and Criterion Validity of the Preliminary Core Dataset for Clinical Trials in Fibromyalgia Syndrome
Objective . Increasing research interest and emerging new therapies for treatment of fibromyalgia ( FM ) have led to a need to develop a consensus on a core set of outcome measures that should be assessed and reported in all clinical trials , to facilitate interpretation of the data and underst and ing of the disease . This aligns with the key objective of the Outcome Measures in Rheumatology ( OMERACT ) initiative to improve outcome measurement through a data driven , interactive consensus process . Methods . Through patient focus groups and Delphi processes , working groups at previous OMERACT meetings identified potential domains to be included in the core data set . A systematic review has shown that instruments measuring these domains are available and are at least moderately sensitive to change . Most instruments have been vali date d in multiple language s. This pooled analysis study aims to develop the core data set by analyzing data from 10 r and omized controlled trials ( RCT ) in FM . Results . Results from this study provide support for the inclusion of the following in the core data set : pain , tenderness , fatigue , sleep , patient global assessment , and multidimensional function/health related quality of life . Construct validity was demonstrated with outcome instruments showing convergent and divergent validity . Content and criterion validity were confirmed by multivariate analysis showing R square values between 0.4 and 0.6 . Low R square value is associated with studies in which one or more domains were not assessed . Conclusion . The core data set was supported by high consensus among attendees at OMERACT 9 . Establishing an international st and ard for RCT in FM should facilitate future metaanalyses and indirect comparisons
