Abstract：
BACKGROUND: Functional bladder outlet obstruction (BOO) in women is postulated to be caused by pelvic floor muscle (PFM) dyssynergia or increased tone. The aim of the present review was to investigate the effect of PFM relaxation training on PFM tone and female BOO symptoms.
METHODS: This was a narrative review using an open search strategy on PubMed with the search terms \"Bladder outlet obstruction\" AND \"female\" AND (\"pelvic floor muscles\" OR \"Kegel\"). The risk of bias of the randomized controlled trials (RCTs) was scored with the Physiotherapy Evidence Database (PEDro) scale (0-10).
RESULTS: Only three RCTs were found. All three RCTs compared different types of exercise, and no trial compared relaxation training with no or sham treatment. None of the trials reported the effect between groups on the reduction of PFM tone. There was a tendency toward positive effect of PFM relaxation training to improve BOO symptoms in women. PEDro score varied between 4 and 7. Few studies yielded information on the immediate effect of any type of PFM relaxation technique on PFM tone.
CONCLUSIONS: Few RCTs have been conducted on the effect of PFM relaxation training on PFM tone and functional female BOO symptoms. There is an urgent need for RCTs with high methodological and interventional quality in addition to basic research on mechanisms of different relaxation techniques on PFM activity.

摘要：
背景：据推测，女性的功能性膀胱出口梗阻（BOO）是由盆底肌（PFM）协同失调或张力增加引起的。本综述的目的是研究PFM放松训练对PFM音调和女性BOO症状的影响。
方法：这是一个叙述性综述，使用PubMed上的开放式搜索策略，搜索术语“膀胱出口梗阻”和“女性”和（“盆底肌肉”或“凯格尔”）。使用物理治疗证据数据库（PEDro）量表（0-10）对随机对照试验（RCT）的偏倚风险进行评分。
结果：仅发现三项随机对照试验。所有三个随机对照试验都比较了不同类型的运动，没有试验将放松训练与无或假治疗进行比较。没有试验报道组间对PFM音调降低的影响。PFM放松训练对改善女性BOO症状有积极作用的趋势。PEDro评分在4和7之间变化。很少有研究得出有关任何类型的PFM弛豫技术对PFM音调的直接影响的信息。
结论：关于PFM放松训练对PFM音调和功能性女性BOO症状的影响，很少进行随机对照试验。除了有关不同松弛技术对PFM活性的机制的基础研究外，迫切需要具有高方法学和介入质量的RCT。
