abstract: OBJECTIVE To evaluate the feasibility of 8 months of supervised exercise therapy in warm water and its effects on the impact of fibromyalgia on physical and mental health and physical fitness in affected women . METHODS Thirty women with fibromyalgia were r and omly assigned to an exercise therapy group ( n = 15 ) or a control group ( inactive ) ( n = 15 ) . The impact of fibromyalgia on physical and mental health was assessed using the Fibromyalgia Impact Question naire and the anxiety state with State-Trait Anxiety Inventory . Physical fitness was measured using the following tests : Canadian Aerobic Fitness ; h and -grip dynamometry ; 10-metre walking ; 10-step stair-climbing and blind 1-leg stance . RESULTS After 8 months of training , the exercise therapy group improved compared with the control group in terms of physical function ( 20 % ) , pain ( 8 % ) , stiffness ( 53 % ) , anxiety ( 41 % ) , depression ( 27 % ) , Fibromyalgia Impact Question naire total scores ( 18 % ) , State-Trait Anxiety Inventory score ( 22 % ) , aerobic capacity ( 22 % ) , balance ( 30 % ) , functional capacity for walking ( 6 % ) , stair-climbing with no extra weight ( 14 % ) and stair-climbing 10 kg-weighted ( 25 % ) . CONCLUSION Eight months of supervised exercise in warm water was feasible and led to long-term improvements in physical and mental health in patients with fibromyalgia at a similar magnitude to those of shorter therapy programmes The present study tested the hypothesis that perceived exertion during prolonged exercise in hot environments is associated with changes in cerebral electrical activity rather than changes in the electromyogram ( EMG ) of the exercising muscles . Therefore ,  electroencephalogram ( EEG )  in three positions ( frontal , central , and occipital cortex ) ,  EMG , rating of perceived exertion ( RPE ) , and core temperature were measured in 14 subjects during  submaximal exercise in normal ( 18 degrees C , control ) and hot ( 40 degrees C , hyperthermia ) environments .  RPE increased from 11 + /- 1 units at 5 min to 20 + /- 0 units at exhaustion ( 50 + /- 3 min ) in the trial with progressive hyperthermia , whereas exercise in the control trial was maintained with a stable core temperature for 1 h without exhausting the subjects . Altered EEG activity was observed in all electrode positions , and stepwise forward-regression analysis identified core temperature and a frequency index of the EEG over the frontal cortex as the best predictors of RPE . In contrast , there were no significant correlations between RPE and any of the measured EMG parameters ( median spectral frequency , root mean square , or amplitude ) , and the EMG parameters were not different in hyperthermia compared with control . Thus hyperthermia does not seem to affect the activation pattern of the muscles . Rather , the linear correlation among core temperature , EEG frequency index , and RPE indicates that alterations in cerebral activity may be associated with the hyperthermia-induced development of fatigue during prolonged exercise in hot environments Objective : To evaluate the efficacy of a treatment programme for patients with fibromyalgia ( FM ) based on self management , using pool exercises and education . Methods : R and omised controlled trial with a 6 month follow up to evaluate an outpatient multidisciplinary programme ; 164 patients with FM were allocated to an immediate 6 week programme ( n = 84 ) or to a waiting list control group ( n = 80 ) . The main outcomes were changes in quality of life , functional consequences , patient satisfaction and pain , using a combination of patient question naires and clinical examinations . The question naires included the Fibromyalgia Impact Question naire ( FIQ ) , Psychological General Well-Being ( PGWB ) index , regional pain score diagrams , and patient satisfaction measures . Results : 61 participants in the treatment group and 68 controls completed the programme and 6 month follow up examinations . Six months after programme completion , significant improvements in quality of life and functional consequences of FM were seen in the treatment group as compared with the controls and as measured by scores on both the FIQ ( total score p = 0.025 ; fatigue p = 0.003 ; depression p = 0.031 ) and PGWB ( total score p = 0.032 ; anxiety p = 0.011 ; vitality p = 0.013 , ) . All four major areas of patient satisfaction showed greater improvement in the treatment than the control groups ; between-group differences were statistically significant for “ control of symptoms ” , “ psychosocial factors ” , and “ physical therapy ” No change in pain was seen . Conclusion : A 6 week self management based programme of pool exercises and education can improve the quality of life of patients with FM and their satisfaction with treatment . These improvements are sustained for at least 6 months after programme completion OBJECTIVE To evaluate the effectiveness and tolerability of two pool-based physical therapies , stretching and Ai Chi , in fibromyalgia symptomatology and sleep quality . METHODS Eighty-one patients , r and omly assigned to stretching ( n=39 ) or Ai Chi ( n=42 ) , received 18 physiotherapy sessions  and were evaluated at baseline , at treatment termination , and after 4 and 12 weeks of follow-up . Main outcome measures were the Fibromyalgia Impact Question naire ( FIQ ) and the Pittsburgh Sleep Quality Index ( PSQI ) . Secondary outcome measures included the Beck Depression Inventory ( BDI ) , the State and Trait Anxiety Inventory ( STAI ) , and the SF-12 Health Survey ( SF-12 ) . Data analysis was done with repeated measures ANOVA and effect size estimation . RESULTS No differences were found between groups but significant reduction in the FIQ and the PSQI scores were observed in Ai Chi but not in stretching group , with larger effect sizes and longer effect duration on sleep measures . BDI scores decreased in stretching but not in Ai Chi group with small effect sizes . Trait-anxiety scores decreased in both groups also with small effect sizes . The mental component summary of the SF-12 increased only in stretching group with effect sizes moderate to large . CONCLUSIONS Although no global differences were found between groups , Ai Chi significantly improved fibromyalgia symptomatology and sleep quality , whereas stretching only improved subjects ' psychological well-being We investigated whether fatigue during prolonged exercise in uncompensable hot environments occurred at the same critical level of hyperthermia when the initial value and the rate of increase in body temperature are altered . To examine the effect of initial body temperature [ esophageal temperature ( Tes ) = 35.9 + /- 0.2 , 37.4 + /- 0 . 1 , or 38.2 + /- 0.1 ( SE ) degrees C induced by 30 min of water immersion ] , seven cyclists ( maximal O2 uptake = 5.1 + /- 0.1 l/min ) performed three r and omly assigned bouts of cycle ergometer exercise ( 60 % maximal O2 uptake ) in the heat ( 40 degrees C ) until volitional exhaustion . To determine the influence of rate of heat storage ( 0.10 vs. 0.05 degrees C/min induced by a water-perfused jacket ) , four cyclists performed two additional exercise bouts , starting with Tes of 37.0 degrees C. Despite different initial temperatures , all subjects fatigued at an identical level of hyperthermia ( Tes = 40 . 1 - 40.2 degrees C , muscle temperature = 40.7 - 40.9 degrees C , skin temperature = 37.0 - 37.2 degrees C ) and cardiovascular strain ( heart rate = 196 - 198 beats/min , cardiac output = 19.9 - 20.8 l/min ) . Time to exhaustion was inversely related to the initial body temperature : 63 + /- 3 , 46 + /- 3 , and 28 + /- 2 min with initial Tes of approximately 36 , 37 , and 38 degrees C , respectively ( all P < 0.05 ) . Similarly , with different rates of heat storage , all subjects reached exhaustion at similar Tes and muscle temperature ( 40.1 - 40.3 and 40 . 7 - 40.9 degrees C , respectively ) , but with significantly different skin temperature ( 38.4 + /- 0.4 vs. 35.6 + /- 0.2 degrees C during high vs. low rate of heat storage , respectively , P < 0.05 ) . Time to exhaustion was significantly shorter at the high than at the lower rate of heat storage ( 31 + /- 4 vs. 56 + /- 11 min , respectively , P < 0.05 ) . Increases in heart rate and reductions in stroke volume paralleled the rise in core temperature ( 36 - 40 degrees C ) , with skin blood flow plateauing at Tes of approximately 38 degrees C. These results demonstrate that high internal body temperature per se causes fatigue in trained subjects during prolonged exercise in uncompensable hot environments . Furthermore , time to exhaustion in hot environments is inversely related to the initial temperature and directly related to the rate of heat storage Aim Previous systematic review s have found hydrotherapy to be an effective management strategy for  fibromyalgia syndrome ( FMS ) .  The aim of this systematic review was to summarize the components of hydrotherapy programs used in r and omized controlled trials . Method A systematic review of r and omized controlled trials was conducted . Only trials that have reported significant FMS-related outcomes were included . Data relating to the components of hydrotherapy programs ( exercise type , duration , frequency and intensity , environmental factors , and service delivery ) were analyzed . Results Eleven r and omized controlled trials were included in this review . Overall , the quality of trials was good . Aerobic exercise featured in all 11 trials and the majority of hydrotherapy programs included either a strengthening or flexibility component . Great variability was noted in both the environmental components of hydrotherapy programs and service delivery . Conclusions Aerobic exercise , warm up and cool-down periods and relaxation exercises are common features of hydrotherapy programs that report significant FMS-related outcomes . Treatment duration of 60 minutes , frequency of three sessions per week and an intensity equivalent to 60%–80 % maximum heart rate were the most commonly reported exercise components . Exercise appears to be the most important component of an effective hydrotherapy program for FMS , particularly when considering mental health-related outcomes Introduction Physical therapy in warm water has been effective and highly recommended for persons with fibromyalgia , but its efficiency remains largely unknown . Should patients or health care managers invest in this therapy ? The aim of the current study was to assess the cost-utility of adding an aquatic exercise programme to the usual care of women with fibromyalgia . Methods Costs to the health care system and to society were considered in this study that included 33 participants , r and omly assigned to the experimental group ( n = 17 ) or a control group ( n = 16 ) . The intervention in the experimental group consisted of a 1-h , supervised , water-based exercise sessions , three times per week for 8 months . The main outcome measures were the health care costs and the number of quality -adjusted life-years ( QALYs ) using the time trade-off elicitation technique from the EuroQol EQ-5D instrument . Sensitivity analyses were performed for variations in staff salary , number of women attending sessions and time spent going to the pool . The cost effectiveness acceptability curves were created using a non-parametric bootstrap technique . Results The mean incremental treatment costs exceeded those for usual care per patient by € 517 for health care costs and € 1,032 for societal costs . The mean incremental QALY associated with the intervention was 0.131 ( 95 % CI : 0.011 to 0.290 ) . Each QALY gained in association with the exercise programme cost an additional € 3,947/QALY ( 95 % CI : 1,782 to 47,000 ) for a health care perspective and € 7,878/QALY ( 3,559 to 93,818 ) from a societal perspective . The curves showed a 95 % probability that the addition of the water-based programme is a cost-effective strategy if the ceiling of inversion is € 14,200/QALY from a health care perspective and € 28,300/QALY from a societal perspective . Conclusion The addition of an aquatic exercise programme to the usual care regime for fibromyalgia in women  is cost effective in terms of both health care costs and societal costs . However , the characteristics of facilities ( distance from the patients ' homes and number of patients that can be accommo date d per session ) are major determinants to consider before investing in such a programme . Trial registration Current controlled trials IS RCT N53367487 OBJECTIVE To evaluate the effects of 6 months of pool exercise combined with a 6 session education program for patients with fibromyalgia syndrome ( FM ) . METHODS The study population comprised 58 patients , r and omized to a treatment or a control group . Patients were instructed to match the pool exercises to their threshold of pain and fatigue . The education focused on strategies for coping with symptoms and encouragement of physical activity . The primary outcome measurements were the total score of the Fibromyalgia Impact Question naire ( FIQ ) and the 6 min walk test , recorded at study start and after 6 mo . Several other tests and instruments assessing functional limitations , severity of symptoms , disabilities , and quality of life were also applied . RESULTS Significant differences between the treatment group and the control group were found for the FIQ total score ( p = 0.017 ) and the 6 min walk test ( p < 0.0001 ) . Significant differences were also found for physical function , grip strength , pain severity , social functioning , psychological distress , and quality of life . CONCLUSION The results suggest that a 6 month program of exercises in a temperate pool combined with education will improve the consequences of FM The aim of this study was to evaluate the effectiveness of aerobic exercise in water pool compared with aerobic exercise performed in sea by women with fibromyalgia ( FM ) . A total of 46 patients were r and omly allocated into two groups : pool group ( 23 patients ) and sea group ( 23 patients ) that performed the same aerobic exercise program . Patients were evaluated baseline and after 12 weeks using : VAS , number of tender points , FIQ , SF-36 , PSQI , and BDI . Both groups improved significantly in post-treatment for all the evaluated variables . There were no significant differences between two groups , except for BDI ( F = 2.418 , P < 0.0001 ) . Aerobic exercise program performed in water ( pool or sea ) was effective for patients with FM . However , sea water exercises have been shown to bring more advantages related to emotional aspects . Then , exercise performed sea water ( thalassotherapy ) is an option for effective treatment with low cost for patients with FM OBJECTIVE To measure mood and physical function of individuals with fibromyalgia , 6 and 12 months following 23 weeks of supervised aerobic exercise . METHODS This is a followup report of individuals who were previously enrolled in 23 weeks of l and -based and water-based aerobic exercise classes .  Outcomes included the 6-minute walk test , Beck Depression Inventory ( BDI ) , State-Trait Anxiety Inventory , Arthritis Self-Efficacy Scale ( ASES ) , Fibromyalgia Impact Question naire ( FIQ ) , tender point count , patient global assessment score , and exercise compliance . Outcomes were measured at the start and end of the exercise classes and 6 and 12 months later . RESULTS Analyses were conducted on 29 ( intent-to-treat ) or 18 ( efficacy ) subjects .  Six-minute walk distances and BDI total scores were improved at followup ( all analyses ) . BDI cognitive/affective scores were improved at the end of 23 weeks of exercise ( both analyses ) and at the 12-month followup ( efficacy analysis only ) . BDI somatic scores were improved at 6-month ( both analyses ) and 12-month followup ( intent-to-treat only ) . FIQ and ASES function were improved at all followup points . ASES pain was improved in efficacy analyses only ( all followup points ) . Tender points were unchanged after 23 weeks of exercise and at followup . Exercise duration at followup ( total minutes of aerobic plus anaerobic exercise in the preceding week ) was related to gains in physical function ( 6- and 12-month followup ) and mood ( 6-month followup ) . CONCLUSION Exercise can improve physical function , mood , symptom severity , and aspects of self efficacy for at least 12 months . Exercising at followup was related to improvements in physical function and perhaps mood OBJECTIVES To evaluate the effects of a 16-week exercise therapy in a chest-high pool of warm water through applicable tests in the clinical practice on the global symptomatology of women with fibromyalgia ( FM ) and to determine exercise adherence levels . DESIGN A r and omized controlled trial . SETTING Testing and training were completed at the university . PARTICIPANTS Middle-aged women with FM ( n=60 ) and healthy women ( n=25 ) . INTERVENTION A 16-week aquatic training program , including strength training , aerobic training , and relaxation exercises . MAIN OUTCOME MEASURES Tender point count ( syringe calibrated ) , health status ( Fibromyalgia Impact Question naire ) ; sleep quality ( Pittsburgh Sleep Quality Index ) ; physical ( endurance strength to low loads tests ) , psychologic ( State Anxiety Inventory ) , and cognitive function ( Paced Auditory Serial Addition Task ) ; and adherence 12 months after the completion of the study . RESULTS For all the measurements , the patients showed significant deficiencies compared with the healthy subjects . Efficacy analysis ( n=29 ) and intent-to-treat analysis ( n=34 ) of the exercise therapy was effective in decreasing the tender point count and improving sleep quality , cognitive function , and physical function . Anxiety remained unchanged during the follow-up . The exercise group had a significant improvement of health status , not associated exclusively with the exercise intervention . There were no changes in the control group . Twenty-three patients in the exercise group were exercising regularly 12 months after completing the program . CONCLUSIONS An exercise therapy 3 times a week for 16 weeks in a warm pool could improve most of the symptoms of FM and cause a high adherence to exercise in unfit women with heightened FM symptomatology . The therapeutic intervention 's effects can be assessed through applicable tests in the clinical practice OBJECTIVE To evaluate the efficacy of a 6-week exercise and educational program for patients with fibromyalgia . METHODS Forty-one subjects were r and omly assigned to the program or served as waiting list controls . Program outcome was assessed with a 6-minute walk test , the Fibromyalgia Impact Question naire , a Self-Efficacy Scale , and a " knowledge " question naire ( based on information provided during the educational sessions ) . Waiting list control subjects subsequently completed the program . Program outcome was reassessed 3 or 6 months post-program . RESULTS The program produced significant improvements in 6-minute walk distance , well-being , fatigue , self-efficacy ( for controlling pain and other symptoms ) , and knowledge . At followup , immediate gains in walk distance , well-being , and self-efficacy were maintained , but gains in fatigue and knowledge were lost . CONCLUSION Short-term exercise and educational programs can produce immediate and sustained benefits for patients with fibromyalgia . The benefits of our program may be due to exercise or education since both interventions were given OBJECTIVE To analyze the long-term efficacy of 2 interventions for female fibromyalgia ( FM ) patients : 1 ) cognitive-behavioral therapy ( CBT ) , and 2 ) a physical exercise (PE)-based strategy . METHODS We conducted a prospect i ve , long-term , r and omized , parallel clinical trial . The outcome variables are physical activity , aerobic capacity , and results of the Fibromyalgia Impact Question naire ( FIQ ) , Short Form 36 , Beck Anxiety and Depression Inventory , Chronic Pain Self-Efficacy Scale , and Chronic Pain Coping Inventory . All were measured at baseline , posttreatment , 6 months , and 1 year . The duration of both treatments was 8 weeks . RESULTS Some items of the FIQ and some strategies to cope with pain improved significantly in both groups after treatment . All variables measuring functional capacity improved significantly in the PE group , whereas only physical activity of the vertebral column improved in the CBT group . There were no differences in anxiety , depression , and self efficacy after treatment in either group . After 1 year of followup , most of the parameters had returned to baseline values in both groups . However , in the PE group , functional capacity remained significantly better . CONCLUSIONS PE and CBT improve clinical manifestations in FM patients only for short periods of time . Improvement in self efficacy and physical fitness are not associated with improvement in clinical manifestations Objective . To follow patients with fibromyalgia six and 24 months after they finished a six-month treatment programme . The programme comprised pool exercise therapy , adjusted to the patients ' limitations , and education based on their health problems . Methods . Twenty-six patients were examined six and 24 months after the completion of the treatment programme  with the Fibromyalgia Impact Question naire ( FIQ ) , SF-36 , the 6-minute walk test , and the Grippit measure . The values obtained at the follow-up examinations were compared with the baseline and post-treatment values . Results . As compared with baseline , symptom severity ( FIQ , SF-36 ) , physical function ( FIQ , SF-36 , 6-minute walk test ) and quality of life ( SF-36 ) still showed improvements six months after the completion of treatment ( p<0.05 ) . Pain ( FIQ , SF-36 ) , fatigue ( FIQ , SF-36 ) , walking ability , and social function ( SF-36 ) still showed improvements 2 years after the completion of the programme as compared with the baseline values ( p<0.05 ) . No significant changes were found for these variables , when the values obtained at the two follow-up examinations were compared with those of the post-treatment examination . Conclusions . Improvements in symptom severity , physical function and social function were still found six and 24 months after the completed treatment programme Objective The aim of this study was to compare pool-based exercise and balneotherapy in fibromyalgia syndrome ( FMS ) patients . Methods Fifty female patients diagnosed with FMS according to the American College of Rheumatism ( ACR ) criteria were r and omly assigned to two groups : group 1 ( n=25 ) with pool-based exercise , and in group 2 ( n=25 ) balneotherapy was applied in the same pool without any exercise for 35 min three times a week for 12 weeks . In both groups , pre- ( week 0 ) and post-treatment ( weeks 12 and 24 ) evaluation was performed by one of the authors , who was blind to the patient group . Evaluation parameters included pain , morning stiffness , sleep , tender points , global evaluation by the patient and the physician , fibromyalgia impact question naire , chair test , and Beck depression inventory . Statistical analysis was done on data collected from three evaluation stages . Results Twenty-four exercise and 22 balneotherapy patients completed the study . Pretreatment ( week 0 ) measurements did not show any difference between the groups . In group 1 , statistically significant improvement was observed in all parameters ( P<0.01 ) except for the chair test at both weeks 12 and 24 . In group 2 , week 12 measurements showed significant improvement in all parameters ( P<0.01 ) except for the chair test and Beck depression inventory . Week 24 evaluation results in group 2 showed significant improvements in pain and fatigue according to visual analogue scale ( VAS ) , 5-point scale , number of tender points , algometric and myalgic scores , and patient and physician global evaluation ( P<0.01 and P<0.05 , respectively ) , while improvements were nonsignificant in morning stiffness , sleep , fibromyalgia impact question naire ( FIQ ) , chair test , and Beck depression inventory parameters in this group . Comparison of the two groups based on the post-treatment ( weeks 12 and 24 ) percent changes and difference scores relative to pretreatment ( week 0 ) values failed to show a significant difference between the groups for any parameter except Beck depression inventory ( P<0.01 ) . Conclusion The results of our study showed that pool-based exercise had a longer-lasting effect on some of the FMS symptoms , but statistical analysis failed to show a significant superiority of pool-based exercise over balneotherapy without exercise . While we believe that exercise is a gold st and ard in FMS treatment , we also suggest in light of our results that balneotherapy is among the valid treatment options in FMS , and further research regarding the type and duration of the exercise programs is necessary OBJECTIVE To evaluate the short- and long-term efficacy of exercise therapy in a warm , waist-high pool in women with fibromyalgia . METHODS Thirty-four women ( mean + /- SD tender points 17 + /- 1 ) were r and omly assigned to either an exercise group ( n = 17 ) to perform 3 weekly sessions of training including aerobic , proprioceptive , and strengthening exercises during 12 weeks , or to a control group ( n = 17 ) . Maximal unilateral isokinetic strength was measured in the knee extensors and flexors in concentric and eccentric actions at 60 degrees /second and 210 degrees /second , and in the shoulder abductors and adductors in concentric contractions .  Health-related quality of life ( HRQOL ) was assessed using the EQ-5D question naire ; pain was assessed on a visual analog scale . All were measured at baseline , posttreatment , and after 6 months . RESULTS The strength of the knee extensors in concentric actions increased by 20 % in both limbs after the training period , and these improvements were maintained after the de-training period in the exercise group . The strength of other muscle actions measured did not change . HRQOL improved by 93 % ( P = 0.007 ) and pain was reduced by 29 % ( P = 0.012 ) in the exercise group during the training , but pain returned close to the pretraining level during the subsequent de-training . However , there were no changes in the control group during the entire period . CONCLUSION The therapy relieved pain and improved HRQOL and muscle strength in the lower limbs at low velocity in patients with initial low muscle strength and high number of tender points . Most of these improvements were maintained long term OBJECTIVE To compare hydrotherapy ( HT ) and conventional physiotherapy ( CP ) in the treatment of fibromyalgia ( FM ) , regarding quality of life ( QOL ) , total sleep time ( TST ) , and total nap time ( TNT ) . METHODS Fifty out patients , all female , 30 - 60 years old , diagnosed with FM , were r and omly assigned to two groups to carry out 3 weeks of treatment with HT or CP . In the beginning and in the end of treatment , patients were evaluated with the SF-36 question naire to measure QOL and the sleep diary for TST and TNT . Data analyses were blind . RESULTS All 24 HT patients increased 1h in TST compared to 19 CP patients . TNT decreased in the HT group . QOL improved for the two groups in all domains when pre- and post-intervention were compared , but there was no difference between groups . CONCLUSION HT is more effective than CP to improve TST and to decrease TNT in FM patients OBJECTIVES To compare the cognitive function performance in patients with fibromyalgia ( FM ) with respect healthy controls and to evaluate the short-term efficacy of exercise therapy in a warm , chest-high pool on pain and cognitive function in women with FM . METHODS Sixty middle-aged women with FM were r and omly assigned to either an exercise training group ( n = 35 ) to perform 3 sessions per week of aquatic training ( 32 degrees C ) including mobility , aerobic , strengthening , and relaxation exercises for 16 weeks , or a control group ( n = 25 ) . Twenty-five healthy women matched for age , weight , body mass index , and educational and physical activity levels were recruited .  Pain was assessed in patients using a syringe calibrated like a pressure dolorimeter , and a visual analog scale . The severity of FM was evaluated using the Fibromyalgia Impact Question naire . Cognitive function was measured in healthy individuals and patients using several st and ardized neuropsychological tests . All patients were measured at baseline and post-treatment . RESULTS At baseline , the healthy group evidence d cognitive performance that was significantly superior to the group of patients with FM in all of the neuropsychological tests . The exercise group significantly improved their pain threshold , tender point count , self-reported pain , severity of FM , and cognitive function , while in the control group the differences were not significant . CONCLUSION An exercise therapy three times per week for 16 weeks in a warm-water pool is an adequate treatment to decrease the pain and severity of FM well as to improve cognitive function in previously unfit women with FM and heightened painful symptomatology OBJECTIVE To compare the clinical effectiveness of aerobic exercise in the water with walking/jogging for women with fibromyalgia ( FM ) . METHODS Sixty sedentary women with FM , ages 18 - 60 years , were r and omly assigned to either deep water running ( DWR ) or l and -based exercises ( LBE ) . Patients were trained for 15 weeks at their anaerobic threshold .  Visual analog scale of pain , Fibromyalgia Impact Question naire ( FIQ ) , Beck Depression Inventory , Short Form 36 Health Survey ( SF-36 ) , and a patient 's global assessment of response to therapy ( PGART ) were measured at baseline , week 8 , and week 15 . Statistical analysis included all patients . RESULTS Four patients dropped out from each group . Both groups improved significantly at week 15 compared with baseline , with an average 36 % reduction in pain intensity . For PGART , 40 % of the DWR group and 30 % of the LBE group answered " much better " at posttreatment . FIQ total score and FIQ depression improvements in the DWR group were faster ( week 8) than the LBE group and kept improving ( week 15 ; P < 0.05 ) . Only the DWR group showed improvements in SF-36 role emotional ( P = 0.006 ) . No significant between-group differences were observed for peak oxygen uptake and other outcomes . CONCLUSION DWR is a safe exercise that has been shown to be as effective as LBE regarding pain . However , it has been shown to bring more advantages related to emotional aspects . Aerobic gain was similar for both groups , regardless of symptom improvement . Therefore , DWR could be studied as an exercise option for patients with FM who have problems adapting to LBE or lower limbs limitations OBJECTIVE To evaluate the effect of exercise on mood and physical function in individuals with fibromyalgia . METHODS Subjects were r and omly assigned to an exercise ( EX ) or control ( CTL ) group . EX subjects participated in 3 30-minute exercise classes per week for 23 weeks . Subjects were tested at entry and at 6 , 12 , and 23 weeks . Tests included the Beck Depression Inventory ( BDI ) , 6-minute walk , State-Trait Anxiety Inventory ( STAI ) , Mental Health Inventory ( MHI ) , Fibromyalgia Impact Question naire ( FIQ ) , Arthritis Self-Efficacy Scale ( ASES ) , and a measure of tender points and knee strength . RESULTS Fifty subjects ( 27 EX , 23 CTL ) completed the study , and 31 ( 15 EX , 16 CTL ) met criteria for efficacy analyses . In efficacy analyses , significant improvements were seen for EX subjects in 6-minute walk distances , BDI ( total , cognitive/ affective ) , STAI , FIQ , ASES , and MHI ( 3 of 5 subscales ) scores . These effects were reduced but remained during intent-to-treat analyses . CONCLUSION Exercise can improve the mood and physical function of individuals with fibromyalgia PURPOSE To evaluate the effects of a 12-wk period of aquatic training and subsequent detraining on health-related quality of life ( HRQOL ) and physical fitness in females with fibromyalgia . METHODS Thirty-four females with fibromyalgia were r and omly assigned into two groups : an exercise group , who exercised for 60 min in warm water , three times a week ( N = 17 ) ; and a control group , who continued their habitual leisure-time activities ( N = 17 ) . HRQOL was assessed using the Short Form 36 question naire and the Fibromyalgia Impact Question naire . Physical fitness was measured using the following tests : Canadian Aerobic Fitness , h and grip dynamometry , 10-m walking , 10-step stair climbing , and blind one-leg stance . Outcomes were measured at baseline , after treatment , and after 3 months of detraining . RESULTS After 12 wk of aquatic exercise , significant positive effects of aquatic training were found in physical function , body pain , general health perception , vitality , social function , role emotional problems and mental health , balance , and stair climbing . After the detraining period , only the improvements in body pain and role emotional problems were maintained . CONCLUSION The present water exercise protocol improved some components of HRQOL , balance , and stair climbing in females with fibromyalgia , but regular exercise and higher intensities may be required to preserve most of these gains OBJECTIVE To evaluate whether changes in muscle strength due to 32 weeks of supervised aquatic training predicted improvements on health-related quality of life ( HRQOL ) . METHODS Thirty women with FM aged 50.8 + /- 8.7 years were r and omly assigned to an experimental group ( n = 15 ) , performing 3 weekly sessions of 60 min of warm-water exercise ; or to a control group ( n = 15 ) . HRQOL was evaluated using the Short Form 36 Health Survey ( SF-36 ) . Maximal unilateral isokinetic strength was measured at 60 degrees/s and 210 degrees/s in the knee extensors and flexors in concentric action and at 60 degrees/s in knee extensors eccentric action . Postural balance was evaluated using the one-leg stance , eyes closed . RESULTS After 32 weeks of water exercise therapy , statistically significant improvements occurred in concentric knee flexors and extensors strength at 60 degrees/s , in eccentric knee extensors and in postural balance . The treatment led to additional improvements in physical function , role physical problems , body pain , general health , vitality , role emotional problems and mental health dimensions of SF-36 . Gains in the concentric knee flexors strength predicted improvements in role of physical problems , whereas those in concentric knee extensors did the same for mental health and role emotional problems . Gains in eccentric knee extensors strength predicted improvements in postural balance . CONCLUSIONS A long-lasting exercise therapy in warm water produced relevant gains in muscle strength at low velocities of movements , some of which predicted improvements in physical problems , emotional problems , mental health and balance . TRIAL REGISTRATION International St and ard R and omized Controlled Trial Number IS RCT N53367487 , information available in http://www.controlled-trials.com/IS RCT N53367487 The CONSORT statement is used worldwide to improve the reporting of r and omised controlled trials . Kenneth Schulz and colleagues describe the latest version , CONSORT 2010 , which up date s the reporting guideline based on new method ological evidence and accumulating experience . To encourage dissemination of the CONSORT 2010 Statement , this article is freely accessible on bmj.com and will also be published in the Lancet , Obstetrics and Gynecology , PLoS Medicine , Annals of Internal Medicine , Open Medicine , Journal of Clinical Epidemiology , BMC Medicine , and Trials
target: Due to the low method ological rigor , the results were insufficient to demonstrate statistical and clinical differences in most of the outcomes
background: Objective : To assess the effectiveness of aquatic physical therapy in the treatment of fibromyalgia .
