Conclusion The main results included reduction in pain , fatigue , number of tender points , depression , and anxiety , with increased functional capacity and quality of life .
Background Fibromyalgia ( FM ) is characterized by chronic and generalized musculoskeletal pain .
There is currently no cure for FM , but palliative treatments are available .
One type of treatment is strength training ( ST ) .
However , there is a need for more information on optimal training protocol s , intensity , and volume needed to improve symptoms .
The aim of this study was to analyze the effects of ST in the treatment of FM through a systematic review of experimental research .
Controlled, cross-sectional, multi-center study of physical capacity and associated factors in women with fibromyalgia
Background Health and physical capacity are commonly associated with disease , age , and socioeconomic factors . The primary objective of this study was to investigate the degree to which physical capacity , defined as muscle strength and walking ability , is decreased in women with fibromyalgia ( FM ) , as compared to healthy women , who are matched for age and level of education . The secondary aim was to investigate whether muscle strength and walking ability are associated with age , symptom duration , activity limitations and , Body Mass Index ( BMI ) in women with FM and control subjects . Methods This controlled , cross-sectional , multi-center study comprised 118 women with FM and 93 age- and education-level-matched healthy women . The outcome measures were isometric knee-extension force , isometric elbow-flexion force , isometric h and -grip force , and walking ability . Differences between the groups were calculated , and for the women with FM analyses of correlations between the measures of physical capacity and variables were performed . Results The women with FM showed 20 % ( p < 0.001 ) lower isometric knee-extension force , 36 % ( p < 0.001 ) lower isometric elbow-flexion force , 34 % ( p < 0.001 ) lower isometric h and -grip force , and 16 % lower walking ability ( p < 0.001 ) , as compared to the healthy controls . All measures of muscle strength in women with FM showed significant weak to moderate relationship to symptom duration ( rs = − 0.23–0.32 ) and walking ability ( rs = 0.25–0.36 ) . Isometric knee-extension force correlated with activity limitations , as measured using the SF-36 Physical function subscale ( rs=0.23 , p = 0.011 ) . Conclusions Physical capacity was considerably decreased in the women with FM , as compared to the age- and education-level-matched control group . All measures of physical capacity showed a significant association with symptom duration . Knee-extension force and walking ability were significantly associated with activity limitations , age , and BMI . It seems important to address this problem and to target interventions to prevent decline in muscle strength . Assessment s of muscle strength and walking ability are easy to administer and should be routinely carried out in the clinical setting for women with FM.Trial registration Clinical Trials.gov identification number : NCT01226784 , Oct 21 , 2010
