To examine the effectiveness of physical therapy intervention for treating diastasis recti abdominis (DRA) in the postpartum population, with emphasis on transverse abdominis (TRA) exercise and kinesiotaping.
Pilot randomized controlled trial.
DRA may be linked to lumbopelvic and gynecological health problems, and there is limited evidence describing effective noninvasive treatments of DRA in postpartum women.
Thirty women, 6 to 12 weeks postpartum with a palpable separation of the rectus abdominis muscles (32.03 ± 4.33 years old; number of births = 2.30 ± 1.34), were randomly assigned to TRA exercise intervention (n = 10), kinesiotaping intervention (n = 8), TRA exercise and kinesiotaping combination intervention (n = 5), or control (n = 7). The primary outcome was inter-recti distance (IRD), measured via ultrasound imaging. Secondary outcomes of low back pain and pelvic floor dysfunction were measured via validated questionnaires (Pelvic Floor Distress Inventory [PFDI-20] and Roland-Morris Disability Questionnaire). Data are presented as means ± standard deviation.
The largest changes in IRD were observed for the TRA exercise–only and TRA exercise + taping groups. There was no statistical difference in IRD change between the TRA exercise–only and TRA exercise + taping groups. Both groups with TRA exercise components were statistically different from the taping-only group and the control group in IRD change.
Based on our preliminary data, exercise targeting the TRA may be an effective treatment method for reducing IRD. Further studies that include a larger patient population, particularly those with low back pain and pelvic floor dysfunction, are needed to replicate these findings and to establish a standardized exercise protocol for DRA.
