“…Most previous studies show that PFM strength decreases after the first vaginal delivery 7 ) . Kım et al 20 ) concluded that pelvic floor muscle contractions induce significantly different vaginal pressures between subjects with nulliparous and vaginal delivery histories, but no significant difference in vaginal pressure was induced between their vaginal delivery group and cesarean delivery group. In the present study, we compared the PFM strength in women who had 1–3, 4–6, and more than 6 deliveries.…”

[Purpose] The purpose of this study was to analyze the pelvic floor muscle (PFM) activity after vaginal birth, and the effect of parity on PFM strength and quality of life (QoL) in women with urinary incontinence. [Subjects and Methods] Patients (n=241) who gave birth vaginally and experienced urinary incontinence were divided into three groups: group 1 consisted of women having 1–3 children, group 2 consisted of women having 4–6 children, and group 3 consisted of women having more than 6 children. All patients underwent detailed examination of the PFM. The Turkish version of the self-administered Incontinence Quality of Life Instrument (I-QoL) questionnaire was used to evaluate the effects of stress urinary incontinence on participants’ QoL. [Results] Comparison of PFM strengths showed a significant intergroup difference. Group 1 showed significantly higher PFM strength scores than those of groups 2 and 3. I-QoL scores related to stress incontinence showed a significant intergroup difference. As number of deliveries increased, quality of life decreased. Comparison of PFM strengths and I-QoL scores related to stress incontinence showed a significant intergroup difference. [Conclusion] Increasing the awareness of PFM training in women will reduce potential postpartum incontinence due to a weak PFM strength; and will increase quality of life.

“…During vaginal childbirth, the PFMs, nerves, and connective tissue are forcibly stretched, compressed, and bruised 8 ) . During vaginal delivery, the PFMs are extended, triggering fatal damage to the perineum 5 ) , and weakening of the contraction force of the PFMs due to vaginal birth can cause disabilities 9 ) . Kisner and Colby 8 ) listed pregnancy and delivery, constipation and the associated inability to empty the bowel, chronic cough, and overweight as causes of weakening of the PFMs.…”

[Purpose] The purpose of this study was to compare the effect of childbirth delivery method on vaginal pressure and abdominal thickness during the Valsalva maneuver (VAL). [Subjects] Thirty healthy female volunteers (26–39 years of age) were selected for this research. Their delivery histories were: nulliparous 10, vaginal delivery 10, and Cesarean delivery 10. None of the participants had a history of incontinence. [Methods] In the crook-lying position, a perineometer probe was inserted into the vagina and the transducer was placed transversely on the right side of the body during the Valsalva maneuver. [Results] There were significant differences in the thickness of the transverses abdominis (TrA) between in all the groups rest and the Valsalva maneuver, and there were significant differences in the internus oblique (IO) in the nulliparous group. During the Valsalva maneuver, there were significant differences in the TrA between the nulliparous group and the vaginal delivery group, and there were significant differences in the IO between the nulliparous delivery group and the vaginal delivery group, and between the nulliparous group and the Cesarean section group. Delivery history changed vaginal pressure, and there were significant differences between the nulliparous group and the vaginal delivery group, and between the nulliparous group and the Cesarean delivery group. [Conclusion] Pregnancy and delivery method may affect pelvic floor and abdominal muscles during the Valsalva maneuver.

“…It has been reported that women with one or more deliveries or vaginal and/or multiple PFM lacerations are more likely to develop dysfunctions in this muscle group 6 , 7 ) . Kim et al 8 ) observed lower PFM pressure in young women who had normal deliveries when compared with their nulliparous counterparts, but there was no difference in PFM function between women with a history of normal deliveries and those who underwent cesareans. A study conducted with 27,900 women showed that the correlation between parity and PFM function is strong in women of reproductive age; however, there are uncertainties regarding repercussions in other periods of the female cycle 6 , 9 , 10 ) .…”

Influence of parity, type of delivery, and physical activity level on pelvic floor muscles in postmenopausal women

et al. 2016

[Purpose] The aim of the present study was to assess the influence of parity, type of delivery, and physical activity level on pelvic floor muscles in postmenopausal women. [Subjects and Methods] This was an observational analytic cross-sectional study with a sample of 100 postmenopausal women, aged between 45 and 65 years, divided into three groups according to menopausal stage: hysterectomized and early and late postmenopause. Patients were assessed for sociodemographic and gyneco-obstetric factors and subjected to a muscle strength test and perineometry. Descriptive statistics, ANOVA, Kruskal-Wallis and multiple regression were applied. [Results] The results showed homogeneity in sociodemographic and anthropometric characteristics. There was no difference in pelvic floor muscle function among the three groups. Type of delivery, parity and physical activity level showed no influence on muscle function. [Conclusion] The findings demonstrate that parity, type of delivery, and physical activity level had no influence on pelvic floor muscle pressure in postmenopausal women. One hypothesis to explain these results is the fact that the decline in muscle function in postmenopausal women is related to the female aging process.
