Abstract
Back ground: Diastasis recti of the abdominal muscles (DRAM), a common problem in pregnancy and after pregnancy, is separation between the rectus abdominis along the linea alba. The prevalence of DRAM is about 66% in women who were in their third trimester of pregnancy.
Objective: to examine and compare the effects of static and dynamic plank exercise on inter- recti distance (IRD) in women postpartum
Methods: A total of 30 women participated in the study and randomly assigned to static plank group (n=10, mean age=32.4), dynamic plank group (n=10, mean age=34.3) and control group (n=10, mean age=35.7). The dynamic plank group performed 4 exercises (rotational plank, cross plank, spiderman plank and jack plank). Static plank group performed 4 exercises (forearm plank, palm plank, TRX plank and buso ball plank). The IRD was measured by Ultrasound imaging (Supersonic aixplorer mach20, France) into millimeter (mm) at pre and post intervention. Three groups were compared with ANCOVA and then post hoc Bonferroni was used to compare pairwise means.
Findings: There were significant differences in IRD from pre to post test for static (29/0 mm to 27.4 mm) and dynamic (30.1 mm to 27/0 mm) groups. Specifically, the IRD significantly decreased in two exercise groups after plank exercise. It should be noted that percentage of IRD change was 10.33% and 5.51% for dynamic and static groups respectively. The examination of effect sizes indicates small and moderate effect for static and dynamic group respectively. The ANCOVA results indicated that with considering pre-test as covariate, there was significant difference in IRD between dynamic and control group (p<0.001) at post-test. however, there was no significant difference in IRD between static and control group (p=0.087), and static and dynamic group (p=0.420) at post-test.
Conclusion: the results of study indicates that both static and dynamic plank exercise could decrease IRD in women post-partum. However, based on study findings, it seems that dynamic group with adding hip flexion, abduction and rotation movements during plank exercise, which could result in greater activity in abdominal muscles, is more effective in decreasing IRD compared with static plank exercise.
