Clinical efficacy of integrated 3D manual pelvic reduction, suspension training, and pelvic belt fixation for postpartum pubic symphysis diastasis.

OBJECTIVE

To evaluate the clinical efficacy of integrating three-dimensional (3D) manual pelvic reduction, suspension training, and pelvic belt fixation in the treatment of postpartum pubic symphysis diastasis (PSD).

METHODS

A total of 136 patients diagnosed with postpartum PSD were randomized into a control group (n = 68) receiving conventional conservative therapy and an intervention group (n = 68) undergoing additional (3D manual pelvic reduction and Redcord suspension training. The primary outcome was pelvic pain assessed by the visual analog scale (VAS). Secondary outcomes included pubic symphysis width (radiographic measurement), functional disability [Oswestry Disability Index (ODI)], quality of life [QoL; 36-Item Short-Form Health Survey (SF-36)], and sleep quality (Pittsburgh Sleep Quality Index (PSQI)].

RESULTS

Post-intervention, the intervention group demonstrated significantly greater improvements in VAS scores, pubic symphysis narrowing, ODI reductions, SF-36 domain score, and global PSQI scores (all P < 0.001) compared to the control group.

CONCLUSION

The combined protocol of 3D pelvic reduction, suspension training, and pelvic belt fixation effectively alleviates pain, restores pelvic alignment, enhances functional recovery, and improves QoL in postpartum PSD patients, representing a potentially promising therapeutic strategy for clinical adoption.
