Objective. Explore the ultrasound characteristics of early postpartum Diastasis Recti Abdominis (DRA) and provide effective data support for its clinical diagnosis and treatment. Method. A total of 458 parturients who were diagnosed with DRA in the Chongqing Maternal and Child Health Hospital from December 2017 to September 2020 underwent postpartum ultrasound examinations. All of which were located at four points: 6 cm above the umbilicus (point 1), 3 cm above the umbilicus (point 2), umbilicus (point 3), and 3 cm below the umbilicus (point 4) to detect the interrectus distance (IRD) in the resting and sit-up state of the parturients postpartum and to study the differences in maternal age, weight, and ultrasound diagnosis of IRD at different stages after delivery. Results. The IRD values of the four measurement points in the resting state of the parturient were significantly greater than the IRD values in the sit-up state. And in the resting state, the IRD value ( 4.31 ± 1.07 cm ) of the point 3 region was the largest, and there were significant differences at different stages of the postpartum women. At the same time, the IRD values of points 3 and 4 have significant differences in parturient of different ages. In addition, the IRD values of the four measurement points of overweight women were higher than those of nonoverweight women. Conclusion. The umbilicus is the best ultrasound evaluation point for early postpartum DRA. The IRD value at this point in the resting state can be used as reference data for evaluating early postpartum DRA, which provides a useful reference for rapid postpartum recovery of parturients.

“…The assessor will then perform all measurements at a later stage using the free Microdicom software. All measurements are to be performed by the same assessor (N-MT), a women’s health physiotherapist with 21 years of clinical experience with both specific training and clinical experience in the use of ultrasound imaging of the pelvic floor and abdomen prior to data collection 17 18. Once the offline measurements are completed, the IRD values of all participants, locations and timepoints will be imported into Stata software for statistical analysis, together with the retrieved background data.…”

Effect of a specific exercise programme during pregnancy on diastasis recti abdominis: study protocol for a randomised controlled trial

et al. 2022

Introduction Diastasis recti abdominis (DRA) is a common condition in pregnant and postpartum women. Evidence for the treatment of DRA is both sparse and weak. As this condition occurs during the last two trimesters of pregnancy and there is a paucity of high-quality studies on a pregnant population, we will conduct a randomised trial on the effect of a specific exercise programme during pregnancy on DRA. Methods and analysis This is an exploratory, assessor-blinded, randomised parallel group trial carried out in a primary healthcare setting in a Norwegian city. 100 pregnant women, both primigravida and multigravida, in gestation week 24 presenting with DRA of ≥28 mm will be included. Participants will be allocated to either an intervention group or a control group by block randomisation. The intervention group will participate in a 12-week specific exercise programme. The control group will not participate in any exercise intervention. Data collection will take place prior to intervention, postintervention at gestation week 37, and 6 weeks, 6 and 12 months postpartum. The primary outcome measure will be change in the inter-recti distance, measured by two-dimensional ultrasonography. Data will be analysed and presented in accordance with international Consolidated Standards of Reporting Trials guidelines and analysed according to the intention-to-treat principle. Ethics and dissemination Ethical approval has been obtained by the regional ethical committee (76296), and all procedures will be performed in adherence to the Helsinki declaration. The study has been registered with ClinicalTrials.gov. Results from this study will be presented at scientific conferences and in peer-reviewed scientific journals. Trial registration number NCT04960800; Pre-results.

An increased inter-rectus distance (IRD) can persist after a pregnancy and may be associated with lumbopelvic dysfunction. Ultrasound imaging (USI) is currently the gold standard for measuring IRD; however, no study has explored the need to standardize the transducer angle during these evaluations. The purpose of this study was to determine whether the angle of the ultrasound transducer relative to the underlying abdominal wall has an effect on measurements of IRD in parous women. Ultrasound images of the linea alba (LA) were captured from 15 women, at rest and during a head lift, beginning with images acquired perpendicular to the LA at the midline, then tilted in 5° increments to 15° in both the cranial and the caudal directions. Repeated-measures analyses of variance were used to test for systematic differences in IRD measurements among the transducer angles in both the rest and the head-lift conditions. An α of 0.05 was used for all tests. No significant effect of transducer angle was found in IRD measurements acquired with participants at rest (=1.814; =0.18) or during a head lift (=1.315; =0.28). When using USI, cranial or caudal tilt errors in transducer angle do not appear to pose a problem when measuring IRD.
