Effectiveness of nonpharmacological conservative therapies for chronic pelvic pain in women: a systematic review and meta-analysis.

Chronic pelvic pain in women is common and hard to treat, and clinicians have long debated which nonpharmacological approaches actually help. This systematic review and meta-analysis pooled 38 randomized controlled trials involving 2168 women to compare therapies such as multimodal physical therapy, psychological approaches, acupuncture, and other tissue-based treatments against inert or nonconservative treatments like placebo, usual care, surgery, or medication. The clearest result was for multimodal physical therapy, which reduced pain intensity more than comparison treatments both shortly after treatment and at intermediate follow-up, with high certainty in the short term. Psychological approaches showed no statistically significant difference in pain, though a slight improvement appeared in sexual function.

Evidence for acupuncture was too uncertain to interpret, and only a limited number of trials examined individual tissue-based treatments, leaving many questions about those approaches unanswered.

If you live with chronic pelvic pain, you've probably wondered whether physical therapy, psychological support, acupuncture, or other non-drug treatments actually make a difference. This review gathered evidence from 38 clinical trials involving over 2000 women to look at exactly that question, comparing these approaches against placebo, usual care, or medical and surgical treatments. The strongest evidence supported multimodal physical therapy, which combines several techniques rather than relying on just one.

Women who received it reported meaningfully lower pain both soon after treatment and months later, and the researchers judged this evidence as reliable. Psychological approaches on their own did not show a clear difference in pain levels, though there was a modest improvement in sexual function.

The evidence on acupuncture was too weak and inconsistent to draw any conclusions, and other individual treatments like stretching or electrical stimulation devices simply haven't been studied enough yet to know how well they work. As with any research summary, these findings describe group averages, and individual experiences can vary.

This review pooled 38 randomized controlled trials (2168 women, mean age 35.1) evaluating nonpharmacological conservative therapies for chronic pelvic pain, using PEDro for methodological quality and GRADE for certainty of evidence. Multimodal physical therapy showed the most robust findings, reducing pain intensity relative to inert or nonconservative comparators in the short term (standardized mean difference -1.69, 95% CI -2.54 to -0.85, high certainty) and intermediate term (standardized mean difference -1.82, 95% CI -3.13 to -0.52, moderate certainty), representing large effect sizes. Predominantly psychological approaches showed no statistically significant difference in pain intensity (standardized mean difference -0.18, 95% CI -0.56 to 0.20, moderate certainty), with a small but statistically significant improvement in sexual function (standardized mean difference -0.28, 95% CI -0.52 to -0.04, moderate certainty).

Acupuncture's pooled estimate for pain intensity favored control non-significantly (standardized mean difference 1.08, 95% CI -1.38 to 3.54), and the wide confidence interval precluded any certainty rating. Tissue-based monotherapies were represented by only a limited number of trials, restricting the evidence base considerably.

Overall, the review supports multimodal physical therapy with high certainty for short-term pain reduction, while other modalities remain insufficiently or inconsistently studied.
