ABSTRACT
AIM: The study aimed at evaluating the effect of posture correction and stretching movements on lordosis and lumbar pain in pregnant women. BACKGROUND: An increased lumbar lordosis during pregnancy is considered one of the most common causes of lumbar pain. METHODS: This quasi-experimental study was performed on 66 pregnant women referred to health centers in Tabriz, Iran, from November 2020 to June 2021. The participants were randomly assigned to the intervention and control groups. The intervention group received training of posture correction movements and stretching exercises during pregnancy from 16 to 18 to 35-37 weeks of pregnancy in six sessions for 45-60 min. The data were collected using a flexible ruler and a visual analog scale. Independent t-tests, repeated measures ANOVA, and ANCOVA tests were used. RESULTS: The mean (standard deviation: SD) of lumbar lordosis increased from 45.12 (2.07) to 54.97 (2.20) in the intervention group at 35-37 weeks and changed from 44.28 (2.03) to 55.54 (3.39) in the control group at 35-37 weeks (adjusted mean difference: -1.24, 95% confidence interval: -2.48 to -0.005, P = 0.04). The mean (SD) of lumbar pain at 28-30 weeks was 2.80 (1.72) in the intervention group and 3.74 (2.23) in the control group (P = 0.09). However, the mean (SD) of lumbar pain at 35-37 weeks in the intervention group 4.38 (2.45) was significantly lower than that in the control group 5.83 (2.96) (P = 0.04). CONCLUSION: This study provides evidence for the potential health benefits of training posture correction and stretching movements on controlling lumbar lordosis and reducing lumbar pain during pregnancy.
