The Efficacy of a Treatment Program Focusing on Specific Stabilizing Exercises for Pelvic Girdle Pain After Pregnancy A Randomized Controlled Trial Britt Stuge, MSc, PT*, Even Lærum, PhD†, Gitle Kirkesola, PT‡, and Nina Vøllestad, PhD* Study Design.A randomized controlled trial with strat- ified block design. Objectives.To evaluate a treatment program focusing on whether specific stabilizing exercises for patients with pelvic girdle pain after pregnancy reduce pain, improve functional status, and improve quality of life. Summary of Background Data.The evidence of effec- tiveness of treatment for pelvic girdle pain is weak. Re- cent research has focused on the importance of activation of muscles for motor control and stability of the lum- bopelvic region. To the authors’ knowledge, the efficacy of applying these principles for pelvic girdle pain has not previously been evaluated in a randomized controlled trial. Methods.Eighty-one women with pelvic girdle pain were assigned randomly to two treatment groups for 20 weeks. One group received physical therapy with a focus on specific stabilizing exercises. The other group received individualized physical therapy without specific stabiliz- ing exercises. Assessments were administered by a blinded assessor, at baseline, after intervention and 1 year post partum. Main outcome measures were pain, functional status and quality of life. Results.There were no dropouts. After intervention and at 1 year post partum, the specific stabilizing exercise group showed statistically and clinically significant lower pain intensity, lower disability, and higher quality of life compared with the control group. Group difference in median values for evening pain after treatment was 30 mm on the Visual Analog Scale. Disability was reduced by more than 50% for the exercise group; changes were negligible in the control group. Significant differences were also observed for ph
