Effect of therapeutic exercises on pregnancy-related low back pain and pelvic girdle pain: Secondary analysis of a randomized controlled trial.

OBJECTIVE

To investigate the effect of a supervised, structured exercise programme on the occurrence and severity of pregnancy-related lumbopelvic pain.

DESIGN

Randomized controlled trial.

SUBJECTS

A total of 45 pregnant women were randomly assigned to 2 groups: an experimental group (n = 20; mean age 32.8 (standard deviation (SD) 3.6) years) and a control group (n = 22; mean age 32.2 years (SD 4.9)).

METHODS

Exercise intervention for the experimental group consisted of aerobic and resistance exercises performed bi-weekly from the date of inclusion into the study until the end of pregnancy, together with at least 30 min of brisk daily walks. A numeric rating scale, Roland-Morris Disability Questionnaire (RMDQ), and Pelvic Girdle Questionnaire (PGQ) were used to measure outcomes. The control group received only standard antenatal care.

RESULTS

There were significant differences between the 2 groups on the numeric rating scale, PGQ and RMDQ scores in the 36th week of pregnancy (p = 0.017; p = 0.005; p < 0.001, respectively) in favour of the experimental group.

CONCLUSION

The exercise programme had a beneficial effect on the severity of lumbopelvic pain in pregnancy, reducing the intensity of pain and the level of disability experienced as a result.
