Objective: The purpose of this study was to conduct a systematic review (SR) of the literature to assess the effectiveness of specific chiropractic care options commonly used for postpartum low back pain (LBP), pelvic girdle pain (PGP), or combination (LBP and PGP) pain.

Methods: A search strategy was developed. Interventions were those manual or other nonpharmacologic therapies commonly used by chiropractors (not requiring additional certifications). The outcomes were self-reported changes in pain or disability self-reported outcomes. We used the Scottish Intercollegiate Guideline Network checklists. Strength of the evidence (excluding cohort studies) was determined using an adapted version of the US Preventive Services Task Force criteria as described in the UK report.

Results: Of the 1611 published articles, 16 were included. These were 5 SRs, 10 randomized controlled trials (RCTs), and 1 cohort study. Postpartum LBP (1 RCT): moderate, favorable strength for spinal manipulation therapy/mobilization. Postpartum PGP (4 RCTs): moderate, unclear strength for exercise; and inconclusive, unclear strength for patient education. Postpartum LBP or PGP (3 SRs and 4 RCTs): inconclusive, unclear strength for exercise, self-management, and physiotherapy; while osteopathic manipulative therapy was inconclusive, favorable.

Conclusion: No treatment option was identified as having sufficient evidence to make a clear recommendation. This SR identified a scarcity of literature regarding chiropractic care and back pain for postpartum women, as well as inconsistency among the terms LBP, PGP, and combination pain.
