Effects of Pelvic Biomechanical Changes on Female Pelvic Floor Dysfunction / 医用生物力学

Pelvic floor dysfunction disease has a high incidence in women after pregnancy. During this special physiological period of women pregnancy, posture of woman pelvis will change, and the pelvic biomechanics will change as well. Such mechanical changes will bring corresponding diseases. The relationship between dynamic changes and occurrence of functional disorders were discussed, the influences of changes in abdominal pelvic mechanics on the pelvic floor after pregnancy were summarized, and the high risk factors of pelvic floor dysfunction （PFD） were investigated, so as to provide the optimal treatment plans and method for pelvic floor rehabilitation treatment.

The relative impact factors of postpartum pelvic floor muscle injury in the region of Tianjin / 天津医药

Objective To investigate the influences of different factors on postpartum pelvic floor muscle injury, and provide clinical evidence to the early prevention of pelvic floor dysfunction (PFD). Methods A total of 65 630 women, who participated the postpartum pelvic floor function screening in Tianjin, from December 2011 to December 2014 were selected in this study. The uniform detect methods was used in this study. The analysis based on the PFD was diagnosed by physi?cians of Women’s and Children’s Health Center in each district. The influences of different factors on postpartum pelvic floor muscle were analyzed. Results There were 19 452 (29.6%) women suffering from postpartum pelvic floor muscle inju?ry, with the abnormal rate 29.6%, which was higher in rural areas than that in urban areas (33.9%vs 27.8%). The abnormal rate was higher in women with junior middle education or below (34.1%) than that in women with senior middle or polytech?nic schooling (30.4%), and women with college or higher education (27.7%). There was a higher abnormal rate in women with vaginal surgery delivery (40.8%) than that in women with natural delivery (32.5%) and women with caesarean section (27.2%). The muscle abnormal rate was higher in women having given two or more than two times of deliveries (34.6% , 31.5%) than those having initial delivery (29.1%). Multiple factor analyses showed that city residency, higher education and less delivery times were protecting factors for postpartum pelvic floor muscle while vaginal surgery was a risk factor for post?partum pelvic floor muscle. Conclusion There is a high incidence of postpartum pelvic floor muscle injury in the region of Tianjin. Analyzing the risk factors and strengthening the management of pelvic floor muscle injury by early prevention or ear?ly treatment would help to reduce the incidence of PFD effectively during pre-pregnancy and perinatal periods.
