Overview
This study is a cohort clinical study. Baseline data were collected from cases recruited at pregnancy, and the eligible subjects were grouped into 3 groups according to different delivery position including supine position group, upright position group, and lateral position group. Different delivery positions along with respectively timeand obstetric conditions were recorded at delivery. Pelvic floor function assessments were performed at postpartum.
Interventions
- Behavioral Lithotomy position
Participants in the lithotomy decubitus position group were in the lithotomy position at the second stage of labor of delivery. - Behavioral Lateral Position
Participants in the lateral position group were in the lateral position at the second stage of labor of delivery. - Behavioral Upright Position
Participants in the upright position group were in the upright position at the second stage of labor of delivery.
Primary outcome measures
- Stress urinary incontence (SUI) occurrence at 6 weeks postpartum [Time frame: at 6 (±1) weeks postpartum]
