Positive outcomes were reported for pain , health-status and tender point count .
There is strong evidence for the use of hydrotherapy in the management of FMS
Hydrotherapy is often used in the treatment of  fibromyalgia syndrome ( FMS ) , however there has been limited evaluation of its effectiveness .
The aim of this systematic review was therefore to examine the effectiveness of hydrotherapy in the management of FMS .
Responsiveness of fibromyalgia clinical trial outcome measures.
OBJECTIVE To assess the responsiveness of the Fibromyalgia Impact Question naire ( FIQ ) , patient ratings of pain intensity , number of tender points , and total tender point pain intensity score to perceived changes in clinical status in patients with fibromyalgia ( FM ) . METHODS Using data from a r and omized  placebo controlled study evaluating efficacy of magnetic therapy in patients with FM , the ability of primary outcomes to detect clinical ly meaningful changes over a 6 month period was assessed by : ( 1 ) degree of association between outcome change scores and patient global ratings of symptom change ( Spearman rank-order correlations ) ; ( 2 ) ability of these scores to discriminate among groups of patients whose perceived health status had changed to varying degrees ( ANOVA ) ; ( 3 ) ability of these scores , individually and jointly , to discriminate between patients who had reported improvement and those who did not ( logistic regression ) ; ( 4 ) effect size , st and ardized response mean , and Guyatt 's statistic were calculated to quantify responsiveness . RESULTS Correlations showed the outcome measures were moderately responsive to perceived symptomatic change . For FIQ , pain intensity ratings and number of tender points , differences in change scores between globally improved and unchanged groups and between globally improved and worsened groups were significant ; for total tender point pain intensity , the globally improved differed from worsened group . FIQ outperformed the other measures in discriminating between patients who reported improvement from those who did not . Summary statistics were consistent with discriminatory analyses , indicating the measures were sensitive to improvement , but relatively unresponsive to decline . CONCLUSION The FIQ was the most responsive measure to perceived clinical improvement and we recommend its inclusion as a primary endpoint in FM clinical trials
Positive outcomes were reported for pain , health-status and tender point count .
