Background : Low back pain (LBP) and pelvic girdle pain (PGP) frequently occur during pregnancy, limiting function, quality of life, and potentially leading to chronic pain and risk of long-term disability. Purpose: To conduct a meta-analysis to determine whether exercise is effective, compared with no exercise, for LBP and PGP (LBPGP) in reducing pain and increasing function in pregnant women. To identify the most effective methods of intervention delivery. Methods: A literature search in PubMed, CINAHL, PEDro, and Cochrane databases yielded 101 articles, of which 5 fi t the criteria to be included in this review. Inclusion criteria-pregnant participants with LBP and/or PGP at baseline, managed with a land-based exercise program; articles classifi ed as level of evidence 2b or higher, and written in English within the last 10 years. Exclusion criteria-studies that excluded women with PGP, or those that lacked a nonexercising comparison group. Effect sizes and 95% confi dence intervals, Q statistics, and Z tests were calculated between and within groups for pain and functional ability outcomes and presented in forest plots. Results: The grand effect size was statistically signifi cant for relieving pain and nonsignifi cant for improving function. Four of the 5 studies reported statistically signifi cant improvement in pain and 2 in function. Studies including stability ball exercise and progressive core stabilization showed signifi cantly improved pain and function and had the highest total exercise time. Discussion: To relieve pain and possibly improve function during advancing pregnancy, women with pregnancy-related LBPGP may benefi t from a 10-week program of supervised, functional, progressive core-focused exercise and/ or yoga program, including a home exercise component. LBP, the pain is so severe that it adversely impacts QOL by disturbing sleep, requiring frequent periods of bed rest, and leading to work absences. 5 , 9 Pregnancy-related PGP can also cause major disability and lifestyle changes as a result of signifi cant activity limitations related to walking, standing, sitting, lying down, and changing positions. 1 Long-term outcomes for PR PGP are less favorable as compared to women experiencing PR LBP because those with PGP are less mobile and experience more
