this study will be conducted to determine the impact of postural balance changes on low back pain during pregnancy

Back pain is a major problem in the general population, and it is thought to be even more common in pregnant women who have given birth. It has been hypothesized that this type of pregnancy-related low back pain (LBP) may be related to changes in lumbar posture, perhaps accompanied by stretching abdominal muscles or specific hormonal effects of pregnancy .During pregnancy, many hormonal, anatomical, and musculoskeletal changes occur. These changes alter the postural balance and increase the risk of falls. Falls during pregnancy can cause maternal and foetal injuries. Moreover, the incidence of falls during pregnancy is higher compared to non-pregnant women of the same age. The risk of falls increases with the gestational age, and most falls are experienced in the third trimester. so, this study will be designed to conduct new information about the relation between postural changes and low back pain during pregnancy
