Introduction And Hypothesis:
This study synthesized the effects of unsupervised behavioral and pelvic floor muscle training (B-PFMT) programs on outcomes relevant to women's storage lower urinary tract symptoms (LUTS) and pelvic floor muscle strength (PFMS).
Methods:
PubMed, CINAHL, Web of Science, and PsycINFO were searched since their inception to August 6, 2019. Randomized controlled trials (RCTs) and quasi-experimental articles that enrolled community women aged 18 years and older and reported storage LUTS outcomes including symptoms, severity, impact, self-reported symptom improvement, and PFMS were screened and extracted. Risk of bias was evaluated, and a narrative synthesis approach was used to synthesize evidence.
Results:
Ten RCTs and three pretest-posttest articles were retrieved. Half of the RCTs had some concerns of bias; the remaining RCTs had high risk of bias. Three pretest-posttest articles had at least some risk of bias. Ten articles aimed to treat urinary incontinence (UI) primarily in middle-aged women, two aimed to prevent UI, and one aimed to improve PFMS in young continent women. Two months post-intervention, UI treatment effectiveness was observed, and cumulative effectiveness was evident in: (1) reduction in the number of incontinent episodes, (2) reduction in the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form and International Consultation on Incontinence Questionnaire-Lower Urinary Tract Symptoms Quality of Life scores, (3) increased patients' global impression of improvement, and (4) improvement of PFMS.
Conclusions:
Unsupervised B-PFMT programs improve outcomes relevant to UI and PFMS in midlife community women who have UI. Their effects on UI prevention and other storage LUTS remain unclear.

The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...
