Impact of exercise on musculoskeletal pain and disability in the postpartum period: a systematic review and meta-analysis.

Musculoskeletal pain in the low back, pelvis, or both is common after childbirth, yet how much exercise actually helps during that first postpartum year hasn't been clearly settled. This systematic review and meta-analysis pooled 37 studies from 15 countries, covering nearly 3,800 postpartum women, comparing exercise programmes against no exercise or against other exercise approaches. Programmes built around trunk-strengthening exercises, done without additional treatments, were linked to greater reductions in lumbopelvic pain severity and related disability, with a similarly favourable pattern for general bodily pain.

The certainty of this evidence was rated moderate, meaning the direction of benefit is reasonably trustworthy but not beyond doubt. Evidence on kinesiophobia, fear of movement due to expected pain, was too limited and inconsistent to draw a conclusion. The main caveat is that individual comparisons often relied on a handful of small trials, so these pooled results should be read as encouraging patterns rather than settled facts.

If you're dealing with low back or pelvic pain after having a baby, you're not alone, and researchers wanted to know whether exercise programmes actually help during that first year postpartum. This review combined findings from 37 studies involving almost 3,800 women across 15 countries, comparing those who did structured exercise, mostly core and trunk strengthening, against those who didn't. The results suggest that exercise focused on strengthening the trunk muscles was linked to lower pain severity and less pain-related disability in the lower back and pelvis, compared with not exercising.

A similar pattern showed up for general bodily pain. Researchers rated this evidence as moderately certain, meaning it's a reasonably solid signal but not proof beyond question. What wasn't clear from this research is whether exercise changes fear of movement after childbirth, since the evidence on that point was too limited and mixed to say either way.

It's also worth remembering that many of the underlying studies were small, so these findings describe a trend worth understanding rather than a guaranteed outcome for any individual.

This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.

This review pooled 37 studies (n=3,769) from 15 countries examining exercise interventions for postpartum musculoskeletal pain, including low back pain, pelvic girdle pain, lumbopelvic pain, and general bodily pain, as well as kinesiophobia. Exercise-only interventions, largely trunk-strengthening protocols, were compared against no-exercise controls. Moderate certainty evidence from four randomised controlled trials (n=210) showed a mean difference of -2.21 points on a 0-10 Visual Analogue Scale for lumbopelvic pain severity favouring exercise, and six trials (n=296) showed a standardised mean difference of -1.17 for related disability, a large effect size, with wide but consistently favourable confidence intervals.

Bodily pain findings from two trials (n=318) followed a similar direction. These are moderate-certainty pooled estimates drawn from a modest number of trials per outcome, so residual heterogeneity and risk of bias in individual studies likely persist despite the overall grading. Evidence regarding kinesiophobia was explicitly described as limited and inconclusive, reflecting either sparse trial data, inconsistent measurement, or both.

Clinicians should interpret the pain and disability findings as a reasonably consistent but not definitive signal, given the small trial counts underlying several pooled estimates.
