Abstract:
Objective:To explore the effects of pelvic-abdominal mechanics exercises during pregnancy on improving pelvic floor function in primiparous women during the perinatal period.Methods:A single-center prospective study selected 200 primipara of singleton pregnancies with prenatal care and delivery established at Shanghai Tongren hospital from June 2022 to June 2023 as the study subjects. Participants were divided into two groups: the exercise group (100 cases) and the control group (100 cases) by using a random number table method, five participants dropped out of the study due to reasons such as follow-up failure. Ultimately, the exercise group consisted of 97 cases, while the control group consisted of 98 cases. Participants who engaged in pelvic-abdominal mechanics exercises for at least 3 months, exercising once a week, were included in the exercise group. Those who did not engage in exercise were included in control group. Comparing the two groups in terms of pregnancy discomfort symptoms, delivery outcomes, postpartum pelvic floor electromyography results, postpartum quality of life, and pelvic floor disease incidence. The statistical methods utilized included independent t-test, Pearson chi-square test, Fisher′s exact test, and Mann-Whitney U test. Results:In the late stage of pregnancy, the VAS score for low back pain was 5.05±1.22 in the exercise group and 5.47±1.55 in the control group, with a statistically significant difference ( t=2.090, P<0.05). The PFDI-20 score was 23.33±8.41 in the exercise group and 25.76±8.34 in the control group, with a statistically significant difference ( t=2.026, P<0.05). The PFIQ-7 score was 19.21±7.69 in the exercise group and 26.66±6.19 in the control group, with a statistically significant difference ( t=6.851, P<0.05). There was no statistically significant difference in sleep quality and incidence of urinary incontinence between the two groups in late pregnancy ( t=1.252, P=0.396, P>0.05). In terms of childbirth outcomes, the exercise group had a vaginal delivery rate of 81.44% (79 cases), while the control group had a rate of 64.28% (63 cases), with a statistically significant difference (χ 2=9.022, P<0.05). The duration of the second stage of labor was (42.68±21.38) minutes in the exercise group and (50.54±21.33) minutes in the control group, with a statistically significant difference ( t=2.178, P<0.05). At 42 days postpartum, the evaluation of pelvic floor function showed that the vaginal pressure in the exercise group was 62.19±10.04, while in the control group it was 52.68±15.55, with a statistically significant difference ( t=-5.074, P<0.05). The MOS grading in the exercise group was 3.82±1.26, whereas in the control group it was 2.34±1.55, with a statistically significant difference ( t=-7.355, P<0.05). In terms of the incidence of postpartum pelvic floor disorders, the occurrence of pelvic organ prolapse was 7.22% in the exercise group and 12.24% in the control group, with no statistically significant difference (χ 2=1.402, P>0.05). The occurrence rate of stress urinary incontinence was 13.4% in the exercise group and 30.61% in the control group, with a statistically significant difference ( P=0.015, P<0.05). Conclusion:Pelvic-abdominal mechanics exercises may have some advantages in reducing symptoms related to perinatal pelvic floor dysfunction, enhancing pelvic floor function, and preventing the occurrence of pelvic floor disease.
