To evaluate the effectiveness of an illustrated home exercise guide targeting the pelvic floor muscles in promoting urinary continence during pregnancy.
A randomized clinical trial was performed with 87 participants, evaluated six times during pregnancy and divided into three groups: Gsup, supervised; Gobs, not supervised, and Gref, women who did not perform the home exercises program. A miction diary and perineometry were used to evaluate urinary incontinence (primary outcome) and pelvic floor muscle strength (secondary outcome), respectively. The Kruskal-Wallis test with post hoc Dunn's and chi-square and Z tests with Bonferroni correction were used for continuous variables and proportions, respectively, with the level of significance set at 5%.
At the end of the study, 6.9% of pregnant women in the Gsup and Gobs had urinary incontinence, while 96.6% of Gref women were incontinent. Regarding pelvic floor muscle function, Gsup and Gobs had mean contractions of 10 and 8.9 cmH2O, respectively, while Gref had a value of 4.7 cmH2O. Both results were significant.
An illustrated home exercise guide targeting the pelvic floor muscles is effective in promoting urinary continence during pregnancy, even without permanent supervision.

PURPOSE: To evaluate the effects of electrical stimulation (ES) of the pelvic floor on the urethra of female rats. METHODS: Forty adult rats were divided at random into four groups of ten animals each: Ctrl - without intervention; Sham - not submitted to ES, but with an electrode inserted into the vagina; Exp6 - submitted to six sessions of ES of the pelvic floor, and Exp12 - submitted to 12 sessions of ES of the pelvic floor. At the end of the experiment, all animals were anesthetized and the middle third of the urethra was removed, fixed in Bouin's fluid and processed for histomorphometric study. Sections were stained with hematoxylin and eosin for morphological and morphometric description, and others were stained with picrosirius red for the quantitation of total collagen. The thicknesses of the muscle layer and of the epithelium were determined, in 4 quadrants of the urethra, by performing 20 measurements per animal. The number of blood vessels present in the lamina propria was counted in the four quadrants over an area of 10³ µm² per quadrant and the images were obtained using the image analysis program AxioVision® REL 4.3 (Carl Zeiss). The collagen and muscle fiber ratios in the urethrae were calculated from two images per quadrant of every slice stained with picrosirius red, employing the Imagelab® Program. Data were subjected to analysis of variance (ANOVA) and the Tukey-Kramer multiple comparison test (p<0.05). RESULTS: The morphometry of the collagen, number of blood vessels and thickness of the epithelium showed no significant changes; however, the thickness of the periurethral muscle tissue increased significantly in Exp12 group, compared to the other groups (Exp12*>Exp6==Ctrl==Sham; *p<0.05). CONCLUSION: Prolonged functional electric stimulation of the pelvic floor induced an increase in periurethral muscle thickness in rats.

PURPOSE: To determine anatomical and functional pelvic floor measurements performed with three-dimensional (3-D) endovaginal ultrasonography in asymptomatic nulliparous women without dysfunctions detected in previous dynamic 3-D anorectal ultrasonography (echo defecography) and to demonstrate the interobserver reliability of these measurements. METHODS: Asymptomatic nulliparous volunteers were submitted to echo defecography to identify dynamic dysfunctions, including anatomical (rectocele, intussusceptions, entero/sigmoidocele and perineal descent) and functional changes (non-relaxation or paradoxical contraction of the puborectalis muscle) in the posterior compartment and assessed with regard to the biometric index of levator hiatus, pubovisceral muscle thickness, urethral length, anorectal angle, anorectal junction position and bladder neck position with the 3-D endovaginal ultrasonography. All measurements were compared at rest and during the Valsalva maneuver, and perineal and bladder neck descent was determined. The level of interobserver agreement was evaluated for all measurements. RESULTS: A total of 34 volunteers were assessed by echo defecography and by 3-D endovaginal ultrasonography. Out of these, 20 subjects met the inclusion criteria. The 14 excluded subjects were found to have posterior dynamic dysfunctions. During the Valsalva maneuver, the hiatal area was significantly larger, the urethra was significantly shorter and the anorectal angle was greater. Measurements at rest and during the Valsalva maneuver differed significantly with regard to anorectal junction and bladder neck position. The mean values for normal perineal descent and bladder neck descent were 0.6 cm and 0.5 cm above the symphysis pubis, respectively. The intraclass correlation coefficient ranged from 0.62-0.93. CONCLUSIONS: Functional biometric indexes, normal perineal descent and bladder neck descent values were determined for young asymptomatic nulliparous women with the 3-D endovaginal ultrasonography. The method was found to be reliable to measure pelvic floor structures at rest and during Valsalva, and might therefore be suitable for identifying dysfunctions in symptomatic patients.

PURPOSE: To evaluate changes to the pelvic floor of primiparous women with different delivery modes, using three-dimensional ultrasound. METHODS: A prospective cross-sectional study on 35 primiparae divided into groups according to the delivery mode: elective cesarean delivery (n=10), vaginal delivery (n=16), and forceps delivery (n=9). Three-dimensional ultrasound on the pelvic floor was performed on the second postpartum day with the patient in a resting position. A convex volumetric transducer (RAB4-8L) was used, in contact with the large labia, with the patient in the gynecological position. Biometric measurements of the urogenital hiatus were taken in the axial plane on images in the rendering mode, in order to assess the area, anteroposterior and transverse diameters, average thickness, and avulsion of the levator ani muscle. Differences between groups were evaluated by determining the mean differences and their respective 95% confidence intervals. The proportions of levator ani muscle avulsion were compared between elective cesarean section and vaginal birth using Fisher's exact test. RESULTS: The mean areas of the urogenital hiatus in the cases of vaginal and forceps deliveries were 17.0 and 20.1 cm², respectively, versus 12.4 cm² in the Control Group (elective cesarean). Avulsion of the levator ani muscle was observed in women who underwent vaginal delivery (3/25), however there was no statistically significant difference between cesarean section and vaginal delivery groups (p=0.5). CONCLUSION: Transperineal three-dimensional ultrasound was useful for assessing the pelvic floor of primiparous women, by allowing pelvic morphological changes to be differentiated according to the delivery mode.

PURPOSES: To investigate the effect of an individualized and supervised exercise program for the pelvic floor muscles (PFM) in the postpartum period of multiparous women, and to verify the correlation between two methods used to assess PFM strength. METHODS: An open clinical trial was performed with puerperal, multiparous women aged 18 to 35 years. The sample consisted of 23 puerperal women divided into two groups: Intervention Group (IG, n=11) and Control Group (CG, n=12). The puerperal women in IG participated in an eight-week PFM exercise program, twice a week. The puerperal women in CG did not receive any recommendations regarding exercise. PFM strength was assessed using digital vaginal palpation and a perineometer. The statistical analysis was performed using the following tests: Fisher's exact, c², Student's t, Kolmogorov-Smirnov for two samples, and Pearson's correlation coefficient. Significance was defined as p<0.05. RESULTS: The participants' mean age was 24±4.5 years in IG and 25.3±4 years in CG (p=0.4). After the exercise program, a significant difference was found between the groups in both modalities of muscle strength assessment (p<0.001). The two muscle strength assessment methods showed a significant correlation in both assessments (1st assessment: r=0.889, p<0.001; 2nd assessment: r=0.925, p<0.001). CONCLUSIONS: The exercise program promoted a significant improvement in PFM strength. Good correlation was observed between digital vaginal palpation and a perineometer, which indicates that vaginal palpation can be used in clinical practice, since it is an inexpensive method that demonstrated significant correlation with an objective method, i.e. the use of a perioneometer.

PURPOSE: To investigate the effect of adding biofeedback (BF) to the training of pelvic floor muscles (PFMT) for the treatment of stress urinary incontinence (SUI). METHODS: A prospective pilot study, randomized and controlled with women with SUI without sphincter deficiency, detected by urodynamic study and who performed the correct PFM contraction. Women with neuromuscular disorders and grade III and IV genital prolapse were excluded. Forty women were randomized into a Control Group and BF Group. The PFMT protocol with BF equipment consisted of three sets of ten slow contractions (tonic), with a holding time of six to eight seconds at each contraction followed by a rest period of equal duration. After each sustained contraction, they performed three to four fast contractions (phasic) in the supine and standing position twice a week, for a total of 12 sessions. We evaluated the effect of adding BF to PFMT on quality of life using King's Health Questionnaire (KHQ) regarding urinary symptoms based on a voiding diary and regarding the function of pelvic floor muscles by digital palpation. The evaluation was performed initially and after 12 treatment sessions. Data are reported as mean and standard deviation. The Mann-Whitney test was used for the analysis of homogeneity and to determine differences between groups, and the Wilcoxon test was used to determine possible differences between the times of observation, with the level of significance set at 0.05. RESULTS: A significant decrease in the scores of the domains assessed by the KHQ was observed in the comparison between groups, except for the general health domain (BF Group: 32.8±26.9 versus Control Group: 48.4±29.5, p<0.13). Accordingly, there was improvement in PFM function after treatment in the BF Group, regarding power (4.3±0.8, p= 0.001), endurance (6.0±2.2, p<0.001) and fast (9.3±1.9, p=0.001). When comparing the groups, the BF Group showed a positive result regarding power (BF Group 4.3±0.8 versus Control Group 2.5±0.9, p<0.001), endurance (6.0±2.2 BF Group versus Control Group 2.7±1.9, p<0.001) and fast (BF Group 9.3±1.9 versus Control Group 4.6 ± 3.2, p<0.001). Reduction of nocturnal urinary frequency (1.2±1.2 versus 0.7±0.9, p=0.02) and of effort urine loss (1.5±1.4 versus 0.6±0.8, p=0.001) was observed in the BF Group. CONCLUSION: The addition of BF to the PFMT for the treatment of SUI, applied according to the protocol described, improved PFM function, reduced urinary symptoms, and improved of the quality of life.

PURPOSE: to evaluate the prevalence of urinary symptoms and association between pelvic floor muscle function and urinary symptoms in primiparous women 60 days after vaginal delivery with episiotomy and cesarean section after labor. METHODS: a cross-sectional analysis was conducted on women from an out patient clinic in São Paulo state, Brazil, 60 days after delivery. Pelvic floor muscle function was assessed by surface electromyography (basal tone, maximal voluntary contraction and mean sustained contraction) and by a manual muscle test (grades 0-5). In an interview, the urinary symptoms were identified and women with difficulty to understand, with motor/neurological impairment, pelvic surgery, diabetes, restriction for vaginal palpation and practicing exercises forpelvic floor muscles were excluded. The χ2 and Fisher Exact test were used to compare proportions and the Mann-Whitney test was used to analyze mean differences. RESULTS: 46 primiparous were assessed on average 63.7 days postpartum. The most prevalent symptoms were nocturia (19.6%), urgency (13%) and increased daytime urinary frequency (8.7%). Obese and overweight women had 4.6 times more of these symptoms (PR=4.6 [95%CI; 1.2-18.6; p value=0.0194]). Stress urinary incontinence was the most prevalent incontinence (6.5%). The mean values found for the basic tone, maximal voluntary contraction and sustained contraction were: 3 µV, 14.6 µV and 10.3 µV. Most of the women (56.5%) had grade 3 muscular strength. There was no association between urinary symptoms and pelvic floor muscle function. CONCLUSION: the prevalence of urinary symptoms was low 60 days postpartum and there was no association between pelvic floor muscle function and urinary symptoms.

PURPOSE: to evaluate the effect of pelvic floor muscle training (PFMT) on female sexual dysfunctions. METHODS: twenty-six women with a diagnosis of sexual dysfunction (sexual desire, arousal, orgasmic disorders and/or dyspareunia) were included in a clinical trial with a before/after approach . The assessment was carried out before, during (after five sessions) and at the end of the treatment (after ten sessions) by two-digit palpation (assessment of pelvic floor muscle, PFM, strength), intravaginal electromyography (EMG) (capture of PFM contraction amplitudes) and Female Sexual Function Index (FSFI, a questionnaire for the evaluation of sexual function). The women underwent PFMT in different positions for ten sessions (once or twice a week). For statistical analysis, absolute and relative frequencies were used for clinical characteristics and PFM strength. The Friedman test was used to compare the FSFI domain scores and EMG values, the Students t-test was used to determine the association between these values and the characteristics of the women, and the Wilcoxon test for percent modification of the EMG. The Mann-Whitney test permitted us to compare these values with clinical characteristics. The Spearman correlation test was used to correlate the EMG values with mean total score. Results were considered statistically significant if p<0.05. RESULTS: a significant improvement (p<0.0001) of FSFI scores was observed at the end of treatment compared to the values observed before and in the middle of treatment. Regarding the EMG, the amplitudes of tonic and phasic contractions increased significantly during treatment (p<0.0001). Pelvic floor strength increased, which 69% of the women presenting grade 4 or 5 at the end of treatment, with a total improvement of sexual complaints. CONCLUSIONS: the PFMT improved muscle strength and electromyography contraction amplitudes, with improved sexual function, indicating that this physiotherapy approach may be successfully used for the treatment of female sexual dysfunctions.
