Effect of Kegel Exercises and Prone Position on Uterine Involution Among Postnatal Mothers: A Quasi-Experimental Study


Abstract

Uterine involution is a crucial physiological process during the postpartum period, and delayed involution may lead to complications such as postpartum hemorrhage and infection. Non-pharmacological interventions that enhance uterine contraction and recovery are increasingly emphasized in postnatal care. This study aimed to evaluate the effectiveness of Kegel exercises combined with prone positioning on uterine involution among postnatal mothers. A quasi-experimental pre-test and post-test control group design was adopted. A total of 200 postnatal mothers who had undergone normal vaginal delivery were selected using purposive sampling and allocated into experimental (n = 100) and control (n = 100) groups. The experimental group received structured instruction on Kegel exercises and prone positioning for three consecutive days, while the control group received routine postnatal care. Uterine involution was assessed using fundal height measurement, uterine consistency, and lochia characteristics. Data were analyzed using descriptive and inferential statistics, including paired t-test. The experimental group demonstrated a significant reduction in uterine involution scores from pre-test (5.58 ± 1.21) to post-test (3.41 ± 1.01). The paired t-test revealed a highly statistically significant difference (t = 17.62, df = 99, p < 0.001), indicating enhanced uterine involution following the intervention. Kegel exercises combined with prone positioning are effective, safe, and low-cost interventions that significantly promote uterine involution among postnatal mothers and can be integrated into routine postnatal nursing care.
