RESULTS The instruments most frequently used were single-item VAS and Biberoglu and Behrman pain score , while multidimensional inventories were used in few studies .
The results of clinical studies in CPP are more frequently based on one-dimensional measurements .
RATIONALE Many types of  pain assessment are available to research ers carrying out clinical trials in chronic pelvic pain ( CPP ) , ranging from a single-item scale to multidimensional inventories .
AIM Our objective was to investigate which assessment s of pain are more commonly used in clinical trials on CPP .
Efficacy of static magnetic field therapy in chronic pelvic pain: a double-blind pilot study.
OBJECTIVE The aim of the study was to determine the efficacy of static magnetic field therapy for the treatment of  chronic pelvic pain ( CPP ) by measuring changes in pain relief and disability . STUDY DESIGN Thirty-two patients with CPP completed 2 weeks and 19 patients completed 4 weeks of r and omized double-blind placebo-controlled treatment at a gynecology clinic .  Active ( 500 G ) or placebo magnets were applied to abdominal trigger points for 24 hour per day . The McGill Pain Question naire , Pain Disability Index , and Clinical Global Impressions Scale were outcome measures . RESULTS Patients receiving active magnets who completed 4 weeks of double-blind treatment had significantly lower Pain Disability Index ( P < .05 ) , Clinical Global Impressions-Severity ( P < .05 ) , and Clinical Global Impressions-Improvement ( P < .01 ) scores than those receiving placebo magnets , but were more likely to correctly identify their treatment ( P < .05 ) . CONCLUSION SMF therapy significantly improves disability and may reduce pain when active magnets are worn continuously for 4 weeks in patients with CPP , but blinding efficacy is compromised
