Objective To explore the benefits of early pelvic floor rehabilitation exercises on the postpartum recovery of primiparous women with different delivery methods

and to provide reference for their clinical diagnosis and treatment.Methods One hundred cases of primiparous women who delivered in a hospital in Zhengzhou from September 2018 to November 2019 were selected asstudy subjects

and all patients were given early pelvic floor muscle rehabilitation training by the same professional physician after delivery

during which five patients dropped out halfway.Among the 95 patients who completed the pelvic floor rehabilitation exercise

36 patients were in the cesarean section group and 59 patients in the normal delivery group.The clinical outcomes of the two groups were compared;the changes in pelvic floor pressure

pelvic floor muscle systolic pressure

sexual function score and Oxford Acute Severity of Illness Score（OASIS） were compared before and after the rehabilitation treatment in the two groups.Results Before treatment

patients in the cesarean section group had significantly higher pelvic floor resting pressure

pelvic floor systolic pressure

pelvic floor class I muscle fiber and class Ⅱmuscle fiber systolic pressure

sexual function score and OASIS score than those in the parity group

and the differences were statistically significant（P <0.05）.After treatment

the resting pelvic floor pressure

pelvic floor systolic pressure

pelvic floor class Ⅰ muscle fiber and class Ⅱ muscle fiber systolic pressure

sexual function score and OASIS were significantly higher in the 2 groups than before treatment

and the differences were all statistically significant（P <0.05）.The treatment effective rate was 96.61 % for patients in the normal delivery group and 86.11% for patients in the cesarean delivery group

with no statistically significant difference（P>0.05）.Conclusion Early pelvic floor rehabilitation exercises for primiparous women with different delivery methods can promote their pelvic floor function recovery and improve their sexual function

and the effect issignificant and has certain clinical application value.
