Abstract：
OBJECTIVE: Investigate effects of integrated training for pelvic floor muscles (PFM) with and without transabdominal ultrasonography (TAUS) imaging-guided biofeedback in postpartum women with pregnancy-related pelvic girdle pain (PPGP).
METHODS: Three-arm, single-blinded randomized controlled trial SETTING: University laboratory PARTICIPANTS: Fifty-three postpartum women with PPGP randomized into stabilization exercise with TAUS-guided biofeedback (BIO+EXE), exercise (EXE), and control (CON) groups.
METHODS: The BIO+EXE and EXE groups underwent an 8-week exercise program, with the BIO+EXE group receiving additional TAUS-guided biofeedback for PFM training during the first 4 weeks. The CON group only received a pelvic educational session.
METHODS: Primary outcomes included self-reported pain (numeric rating scale) and disability (pelvic girdle questionnaire). Secondary outcomes included functional tests (active straight leg raising [ASLR] fatigue, timed up-and-go, and 6-meter walking tests) and muscle contractibility indicated by muscle thickness changes for abdominal muscles and bladder base displacement for PFM (ultrasonographic measures).
RESULTS: The BIO+EXE group had lower pain [1.8 (1.5) vs. 4.4 (1.5), mean difference -2.6, 95% confidence interval (CI) -3.9 to -1.2] and disability [14% (10) vs. 28% (21), mean difference -14, 95% CI -25 to -2] and faster walking speed [3.1 seconds (1) vs. 3.3 seconds (1), mean difference -0.2, 95% CI -1.0 to -0.2] than the CON group. The EXE group only had lower pain intensity compared to the CON group [2.7 (2.0) vs. 4.4 (1.5), mean difference -1.7, 95% CI -3.1 to -0.4]. No significant differences were observed among groups in timed up-and-go, ASLR fatigue, or muscle contractibility.
CONCLUSIONS: Integrated training for PFM and stabilization with TAUS-guided biofeedback seems to be beneficial for reducing pain and disability in postpartum women with PPGP. CONTRIBUTION OF THE PAPER.

摘要：
目的：研究盆底肌肉综合训练（PFM）联合或不联合经腹超声（TAUS）成像引导的生物反馈对妊娠相关的盆腔带疼痛（PPGP）产后妇女的影响。
方法：三臂，单盲随机对照试验设置：大学实验室参与者：53名患有PPGP的产后妇女随机进入TAUS指导的生物反馈（BIO+EXE）的稳定运动，练习（EXE），和对照组(CON)。
方法：BIO+EXE和EXE组进行了为期8周的锻炼计划，BIO+EXE组在前4周内接受额外的TAUS指导的生物反馈进行PFM训练。CON小组仅接受了骨盆教育。
方法：主要结果包括自我报告的疼痛（数字评定量表）和残疾（骨盆带问卷）。次要结果包括功能测试（主动直腿抬高[ASLR]疲劳，定时向上和向上，和6米步行测试）以及由腹部肌肉的肌肉厚度变化和PFM的膀胱底部位移指示的肌肉收缩性（超声检查）。
结果：BIO+EXE组疼痛较低[1.8（1.5）vs.4.4(1.5),平均差-2.6，95%置信区间(CI)-3.9至-1.2]和残疾[14%(10)与28%（21），平均差-14，95%CI-25至-2]和更快的步行速度[3.1秒（1）vs.3.3秒(1),与CON组相比，平均差-0.2，95%CI-1.0至-0.2]。与CON组相比，EXE组仅具有较低的疼痛强度[2.7（2.0）vs.4.4(1.5),平均差异-1.7，95%CI-3.1至-0.4]。在定时上行和上行的组间没有观察到显著差异，ASLR疲劳,或肌肉收缩性。
结论：采用TAUS指导的生物反馈进行PFM和稳定化综合训练似乎有利于减轻PPGP产后妇女的疼痛和残疾。论文的贡献。
