Abstract Background: Decreasing the endurance of trunk muscles and chronic low back pain are common during pregnancy and postpartum period. Stabilizing exercises activating deep local muscles in coordination with global muscles are recommended for the treatment of pregnancy and postpartum related lumbopelvic pain. The purpose of this study is to investigate the effect of core stability training program on pain, disability and endurance of extensor and flexor trunk muscles in females suffering from chronic low back pain in postpartum. Methods: 24 non-athlete females after 4-weeks of normal delivery participated in this study were divided equally and randomly in control (12 people) and experimental (12 person) group. Experimental group performed regular home exercise therapy for four consecutive weeks (6 sessions per week, each lasting 30 minute a day) in their houses, while patients in the control group did not participate in any specific program. For data collection the Oswestry Questionnaire (OSWQ), VAS scale, McGill and Biering-Sorensen tests were used. For analyzing the data, also, T-test was used. Results: The results of this study showed that in experimental group there is a significant reduction in the pain (p=0.001), disability (p=0.004) and also there is a significant increase in the endurance of flexsor muscles (p=0.031), lateral flexsor (p=0.017) and extensor trunk muscles (p=0.042) than control group in posttest. Conclusions: According to results we can suggest that performing 4-week exercise core stability training can lead to decrease in pain, developing ability and increasing endurance of trunk muscles in females suffering from chronic low back pain during postpartum period.
