Comparison of rates of normal pelvic dynamic pressure and normal electrophysiological function of pelvic floor muscle in primiparous women who received combined spinal-epidural analgesia during labor (n = 143) or no analgesia at all (n = 142).

CSEA, combined spinal-epidural analgesia.
*Defined as 80–150 cmH2O.
**Defined as an International Muscle Strength Detection score of 4 or 5 for both type I and type II fibers.
***Defined as a fatigue degree of 0.
****Chi-squared test
