Background: Postpartum period begins immediately after the birth of child as the mother’s body, including the hormone level and the uterus size, returns to non –pregnant state. It is characterized by three distinct phases; initial/acute period, subacute postpartum period and delayed postpartum period. It is a critical stage in which a series of changes occur in a woman. This study aimed to assess the effectiveness of yoga on low back pain intensity, physical and psychological function in postpartum women. However, there is limited evidence examining the effectiveness of yoga in relieving pain and improving physical as well as psychological function in women with postpartum low back pain.

Method: Forty primigravida postpartum women in the age group of 21-26 years were recruited via purposive sampling technique. The participants were randomly allocated in two groups: intervention group (n=20) (pavan muktasana, dandasana, chaturanga dandasana), pranayama (anulom vilom), meditation & control group (n=20) standardised ergonomic advises, postural education, patient education and personalised psychological education was given to the participants in the control group. The outcome measures for pain intensity, physical and psychological function was reassessed on 4^th 8^th & 12^th week

Result: The result of the present study revealed that when both the groups were compared on the basis of their effect size it was observed that intervention group had significant and better results than the control group.
