Effect of postpartum rehabilitation exercise program(5R system) using visual feedback in Rehabilitative Ultrasound Imaging

This study aimed to evaluate the efficacy of a real-time visual feedback-based postpartum rehabilitation exercise program, known as the 5R system.This study aimed to evaluate the efficacy of a real-time visual feedback-based postpartum rehabilitation exercise program, known as the 5R system.

thirty-nine women who had vaginal deliveries and were within five weeks postpartum participated in the study. Participants were divided into two groups: Group 1 (n=19) engaged in the 5R system program, consisting of a 50-minute session twice a week for six weeks. The 5R system comprises a four-phase rehabilitation exercise program, but this study focused only on the second phase, which included the following exercises: visual feedback training for the rectus abdominis(RA) and transversus abdominis(TrA) using Rehabilitative Ultrasound Imaging(RUSI), strengthening of the hip adductor and iliopsoas, and pelvic movement training. Group 2 (n=20) performed aerobic exercises twice a week for six weeks, with each session lasting 20-35 minutes at an intensity of 50-65%.

Both groups showed significant reductions in inter recti distance(IRD) and body weight (p0.05). Group 1 experienced an increase in muscle thickness of the RA during contraction and relaxation (p0.05). A significant difference in the post-pre change of RA thickness during relaxation was observed between Group 1 and Group 2 (p0.05). Additionally, trunk extension and flexion strength increased significantly in Group 1 (p0.05). In contrast, skeletal muscle mass decreased in Group 2 (p0.05), while hip extension and knee extension strength increased significantly (p0.05).

Appropriate postpartum exercise positively impacts women's physical recovery. The results indicated reductions in IRD and body weight, increases in muscle thickness, and improvements in strength, highlighting the benefits of targeted rehabilitation exercises.

We will learn how to apply visual feedback exercises using RUSI to address diastasis recti in postpartum women. They will also be able to compare the effectiveness of a program that combines strength and aerobic exercises with one that includes only aerobic exercises. This knowledge will enable physical therapists and all professionals in the rehabilitation field to provide appropriate exercise interventions for women after childbirth.
