Almost 45% of all pregnant women and 25% of all women postpartum suffer from pelvic girdle pain and/or low back pain as it has been suggested that increased motion of the three joints in the pelvic ring is one of the causes of back and pelvic pain. The aim: was to investigate the effect of trunk flexion exercise versus extension exercise program on post-natal low back pain. Material and methods: 30 patients with post- natal low back pain, their ages ranged from 25to 35 years old and their body mass index (BMI) wasn{u2019}t exceed than 35kg/m² were enrolled in the study they were randomly assigned into 2 equal groups: flexion and extension exercise group. Visual analogue scale (VAS), Oswestry Disability Index and Tape measurement to measure range of motion of the flexion and extension of the lumbar spine (ROM) were measured for all participants pre- and post-treatment period. Results: There were significant differences regarding VAS and ODI between both groups post treatment. But there was no significant difference between the both groups regarding both flexion and extension ROM post treatment. Conclusion: combination of both flexion and extension exercise program is necessary to improve pain functional disability in patients with post natal low back pain. ER -
