Is pelvic floor muscle training effective for symptoms of overactive bladder in women? A systematic review.

BACKGROUND: Overactive bladder (OAB) syndrome can be very bothersome and is associated with impaired quality of life and work productivity. OBJECTIVE: To evaluate the effect of pelvic floor muscle training (PFMT) on OAB symptoms in women. Furthermore, to assess the influence of PFMT on pelvic floor muscle (PFM) function, satisfaction with treatment, side effects, adherence and the quality of exercise reporting. DATA SOURCES: Systematic review of randomized controlled trials (RCTs). Electronic search was conducted on MEDLINE/PubMed, Embase, CINAHL, SciELO, SCOPUS, Web of Science and Physiotherapy Evidence Database (PEDro). The risk of bias was assessed using the PEDro scale. The Consensus on Exercise Reporting Template (CERT) was used to assess the quality of exercise reporting. STUDY SELECTION: Full text RCTs including non-pregnant female participants, investigating PFMT vs inactive control or usual care, other life style modifications or other interventions. SYNTHESIS METHODS: Descriptive analysis. RESULTS: Eleven RCTs were included. There was considerable heterogeneity of PFMT protocols, outcome measures and follow-up periods. Hence, a qualitative analysis was undertaken. PFMT provided a significant reduction of OAB symptoms in five studies with a reduction in urinary frequency (n=1), and urgency urinary incontinence (n=4). PFM function was assessed in three studies, and two studies found improvement in favor of PFMT. LIMITATIONS: A meta-analysis was not possible due to huge heterogeneity of included studies. CONCLUSION: PFMT might reduce OAB symptoms, however, due to many limitations of the published studies it is not possible to clearly determine the effect of PFMT on OAB symptoms and PFM function.

Pelvic floor muscle function and EMG in nulliparous women of different ages: a cross-sectional study.

BACKGROUND: Although aging is considered a risk factor for pelvic floor muscle dysfunction (PFMD), the effect of aging on the function of the pelvic floor muscles (PFM) remains unclear. OBJECTIVE: To compare PFM function and activity in nulliparous women in different age groups. METHODS: This was a cross-sectional study in which 70 women with ages between 18 and 69 years were divided into five age groups for evaluation. Initially, medical histories were taken, and then the PFM function was assessed using digital palpation (Modified Oxford Scale), manometry and surface electromyography (sEMG). The Kruskal-Wallis test was applied to check the differences between the groups. The Spearman correlation coefficient was used to verify the correlations between age and PFM function, manometry values and sEMG. A significance level of 5% was adopted. RESULTS: No significant differences were observed between the different age groups in PFM digital palpation, manometry values and sEMG. There was a low negative correlation between age root mean square and peak of sEMG signals. CONCLUSION: This study found no difference in PFM function and activity between nulliparous women in the five different age groups. Future long-term large prospective studies are required to confirm these findings.

The effects of mode delivery on postpartum sexual function: a prospective study.

OBJECTIVE: To determine the effect of mode of delivery and perineal injury on sexual function at 6 and 12 months postpartum. DESIGN: Prospective cohort study. SETTING: Tertiary women's hospital in Melbourne, Australia. POPULATION: A cohort of 440 primigravid women. METHODS: The Female Sexual Function Index (FSFI) was completed at first visit (7-19 weeks of gestation), and at 6 and 12 months postpartum. MAIN OUTCOME MEASURES: A statistically significant difference in total FSFI or domain scores over time according to mode of delivery or perineal injury. RESULTS: In this cohort 54% of women had a normal vaginal delivery, 21% had an instrumental delivery, and 25% gave birth by caesarean section. No difference was found in total FSFI or domain scores according to mode of delivery over time between antenatal assessment and 12 months postpartum. Pain was decreased in the caesarean group only at 6 months postpartum. All groups showed pain scores at 12 months that were comparable with antenatal levels. For those who gave birth vaginally, 27% had an intact perineum, 50% had an episiotomy, and 6%, 14%, and 3% had first, second, and third-degree tears, respectively. The only differences between groups were found over time according to perineal injury at 6 months in the arousal domain. At 12 months, total FSFI and domain scores were no different to initial scores. CONCLUSIONS: At 12 months postpartum sexual function has returned to early pregnancy levels, irrespective of mode of delivery or perineal injury.
