The aim of this study is to determine pelvic floor muscle (PFM) function in second trimester women with and without pelvic girdle pain (PGP).
Fifty-five pregnant women with and without PGP were recruited in the second trimester who met inclusion for self-reported pain. Vaginal examination was performed assessing superficial and deep PFM tenderness, contract/relax patterns, and muscle strength.
Fifty-one patients (26 with PGP and 25 without) were included in the final analyses. Significantly more patients in the PGP group had bilateral levator ani and obturator internus tenderness compared with the no pain group (Fisher's exact test (FET) P < 0.001). No other significant group differences were found.
There is an association between PGP and deep but not superficial PFM tenderness in pregnancy. Lack of accompanying PFM dysfunction in PGP during pregnancy may reflect pain duration.
本研究旨在确定妊娠中期有无骨盆带疼痛（PGP）的女性的盆底肌肉（PFM）功能。
招募了55名妊娠中期有或无PGP的孕妇，她们均符合自我报告疼痛的纳入标准。进行了阴道检查，评估浅表和深部PFM压痛、收缩/放松模式以及肌肉力量。
51名患者（26名有PGP，25名无PGP）纳入最终分析。与无疼痛组相比，PGP组中双侧肛提肌和闭孔内肌压痛的患者明显更多（Fisher精确检验（FET）P < 0.001）。未发现其他显著的组间差异。
妊娠期间PGP与深部而非浅表PFM压痛之间存在关联。妊娠期间PGP患者缺乏伴随的PFM功能障碍可能反映了疼痛持续时间。
