RESUMEN
INTRODUCTION AND HYPOTHESIS: Pregnancy is associated with an increase in pelvic floor dysfunction. Yoga, an ancient Indian practice involving asanas (physical postures), pranayam (breathing patterns) and meditation, can help women to control their pelvic floor muscles. However, the literature to support yoga as a remedy for pelvic floor dysfunction is lacking. We hypothesized that yoga could be an important method in improving pelvic floor dysfunction in pregnancy. METHODS: In a randomised control study, 200 pregnant women matched for age, weight, parity and physical activity were randomised at the 13- to 20-week period of gestation into two groups: group I (n = 100, undergoing yoga therapy) and group II (n = 100, given usual antenatal care). A trained instructor provided two physical sessions, each lasting for 60 min and further online sessions for 5 days a week for 3 months. The Pelvic Floor Distress Inventory (PFDI-20) questionnaire was used to assess the primary outcome at recruitment, 32 weeks (antenatal), 1 week and 6 weeks post-partum in both groups. RESULTS: In the 200 women randomised and matched for age and parity, there were no complications seen throughout the pregnancy and none of the patients was lost to follow-up in either group. The proportion of women exhibiting a decline in PFDI-20 scores was greater in group 1 (24%) than in group 2 (8%). The mean difference of scores between recruitment and 6 weeks post-partum was statistically significant (p value = 0.0026). CONCLUSIONS: Yoga in pregnancy significantly improves pelvic floor dysfunction in an easy manner with no proven adverse effects.
