Cardiovascular responses to pelvic floor muscle contraction in healthy women: Prospective study.

OBJECTIVE: Analyze the acute heart rate and blood pressure responses to two protocols of pelvic floor muscles contractions in premenopausal and postmenopausal women. METHODS: Fifty-four women without pelvic floor muscles disorders were eligible and allocated into two groups: premenopausal and postmenopausal. The groups underwent two protocols and the pelvic floor muscle endurance, heart rate, and blood pressure values were monitored. Both protocols included 10 pelvic floor muscles contractions; one series contained contractions lasting 5 s with 5 s of rest between each contraction and the other series contained contractions lasting 10 s with 10 s of rest. RESULTS: In both groups, there was a significant increase in the heart rate during pelvic floor muscles contractions (premenopausal: 71.0 ± 7.3 and 80.3 ± 7.7; postmenopausal: 65.4 ± 6.6 and 73.6 ± 6.6, at rest and contractions peak, respectively) and in systolic blood pressure immediately after the contractions. The observed values during exercise returned to basal values seconds after the contractions. A positive correlation between heart rate and vaginal squeeze pressure (r = 0.45, p = 0.0007 and r = 0.48, p = 0.0003, 5- and 10-s series, respectively) was observed. CONCLUSION: The proposed protocol of isometric pelvic floor muscles contractions caused an increase in heart rate and blood pressure within the normal range and might not represent a cardiovascular risk for healthy postmenopausal women without urinary incontinence and without cardiovascular dysfunctions.

Disability and functioning of women with low-risk pregnancy: Assessment using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0).

OBJECTIVE: To evaluate the disability and functioning of women with low-risk pregnancy in the second and third gestational trimesters. METHODS: A longitudinal observational study was conducted from June 5, 2015, to April 30, 2016, in Family Health Units in the city of Santa Cruz, Rio Grande do Norte, Brazil, involving women who were in the second trimester of pregnancy where the pregnancy had been classified as low-risk. A form was designed specifically for the study to collect sociodemographic, urogynecological, and obstetric data. Functioning and disability were assessed using WHODAS 2.0, and descriptive and inferential statistical analyses were performed. RESULTS: Higher levels of disability were observed in cognition in the second trimester (P=0.021), while mobility and life activities domains had higher scores (higher score meaning the woman was more adversely affected) in the third trimester (P=0.007 and P=0.029). Urinary incontinence in the second trimester affected functioning in participation (P=0.023). Pain affected life activities (P=0.023) in the second trimester and participation in the third trimester (P=0.044); and general functioning (P=0.050 and P=0.025), mobility (P=0.002 and P=0.001), and self-care (P=0.0446 and P=0.023) in the second and third trimesters, respectively. CONCLUSION: The findings showed that, even in a low-risk pregnancy, functioning can be affected in different domains. The identification of impairments to functioning could enable improvement in care. Longitudinal studies involving the first trimester and postpartum are necessary to gain insight into women's disability and functioning during the pregnancy-puerperal period.

Individual and group pelvic floor muscle training versus no treatment in female stress urinary incontinence: a randomized controlled pilot study.

OBJECTIVE: To compare the effects of pelvic floor muscle training (PFMT) performed during group treatment sessions (GT) and individual treatment sessions (IT) to a control group (CG) of women with stress urinary incontinence (SUI). HYPOTHESIS: The group treatment sessions would have better effects compared to individual treatment sessions. STUDY DESIGN: This randomized controlled pilot study included women aged over 18 years, who complained of urinary leakage on stress and who had not undergone physical therapy for SUI before. Forty-nine women were randomly allocated to the PFMT in group treatment session (GT) (n=17), PFMT in individual treatment session (IT) (n=17) and control group (CG) (n=15). The study was carried out in an outpatient physical therapy department in São Carlos, Brazil. Subjects on intervention groups were treated with the same PFMT protocol for 6 weeks, with two 1-h weekly sessions. The GT group carried out the PFMT in group treatment session and IT group in individual treatment session. The CG did not receive any treatment during the corresponding time. They were evaluated before and after treatment for primary outcome, urinary loss, and secondary outcomes, King's Health Questionnaire, pressure perineometry, pelvic floor muscle strength by digital palpation and subjective satisfaction. Participants, evaluator and the physical therapist were not blinded. Forty-five women completed the study and were included in the analysis. The statistical analysis was performed using Wilcoxon test for intragroup analysis and Kruskal-Wallis and Mann-Whitney test for intergroup analysis (p<0.05). RESULTS: In intragroup analysis, there was a significant reduction in urinary loss measured by pad test only in the IT group. For primary outcome, there was a significant difference only after treatment between GT and CG (p<0.0001; effect size -0.91; 95% confidence interval from 0.56 to 5.80) as well as between IT and CG (p<0.0001; effect size -0.90; 95% confidence interval from 0.54 to 5.84). There were differences after treatment in GT and IT groups for secondary outcomes: perineometry, muscle strength and in the domains of the quality of life questionnaire. For the CG group, there were not significant differences in any variables. In intergroup analysis for all variables, there were no differences between GT and IT groups. The two treated groups had similar subjective satisfaction (86%). There were no complaints of adverse effects due to treatment from either group. CONCLUSION: The results indicated similar improvement in clinical variables and in satisfaction with the treatment between IT and GT.
