Women with diastasis recti abdominis might have weaker abdominal muscles and more abdominal pain, but no higher prevalence of pelvic floor disorders, low back and pelvic girdle pain than women without diastasis recti abdominis

Correlation between self-reported low back pain and morphological changes in abdominal wall muscles

BACKGROUND

Morphological changes in the abdominal wall muscle in diastasis recti abdominis (DRA) patients with low back pain (LBP) symptoms and whether there is a wider interrectus distance (IRD) remain unclear.

OBJECTIVE

The aim of this study was to determine the correlation between DRA severity and LBP and the morphological differences in abdominal wall muscles between patients who presented with symptoms of LBP and those who were asymptomatic.

METHODS

A total of 57 postpartum DRA patients were enrolled, including 21 without LBP, 36 with LBP, and 30 healthy nulliparous women. The numerical rating scale (NRS) was used to evaluate the degree of LBP. The IRD and muscle thickness of the abdominal muscles were measured via an ultrasonography device at the end of a natural breathing cycle.

RESULTS

The abdominal muscles of the rectus abdominis (RA), external oblique muscle (EO), and transversus abdominis (TrA) in the DRA patients were significantly thinner than those in the control group (p< 0.05), whereas the difference in the internal oblique muscle (IO) was not significant (p> 0.05). There were no statistically significant differences in abdominal muscle thickness or the IRD regardless of whether the patients with DRA had LBP symptoms, with similar findings between the NRS score and DRA severity (P> 0.05).

CONCLUSION

In DRA patients within one year postpartum, no significant difference was found in the severity of DRA or abdominal muscles, regardless of whether they were complicated by LBP symptoms. Shortening the IRD alone may not be beneficial for improving LBP symptoms in DRA patients. The relationship between DRA and LBP and the role of the abdominal muscles in postpartum LBP should be interpreted with caution.

Mothers' experiences living with diastasis recti abdominis - an interview study

BACKGROUND

Diastasis recti abdominis (DRA) is a common postpartum condition. Knowledge is scarce on how mothers perceive living with DRA. The interaction between healthcare providers and patients plays a significant role in shaping the healthcare service experience. Women suffering from typical women's diseases tend to experience not being taken seriously or listened to when seeking healthcare. The aim of this study was to explore mothers' experiences living with DRA.

METHODS

Semi-structured individual interviews were conducted with six Norwegian mothers, age 32-41, presenting with a clinically significant DRA. Topics discussed were how the condition is experienced, how it affects different aspects of day-to-day life and experiences with healthcare services. The data was analyzed using systematic text condensation.

RESULTS

DRA had an impact on everyday life among the mothers included in this study. Three major themes emerged: (I) The path to obtaining knowledge and understanding of DRA, (II) DRA - intertwined with health issues and physical limitations and (III) A changed belly - on self-image & social interactions. The mothers experienced uncertainties and frustration when trying to learn about DRA. The limited knowledge of the condition made it hard to differentiate if the experienced symptoms were caused by presence of DRA or from other health issues. Several mothers felt misunderstood.

CONCLUSION

DRA is a multifaceted condition affecting many aspects of day-to-day life in various dimensions, like physical, emotional, and social. This study contributes to a wider understanding of living with DRA, which might guide healthcare professionals in providing support for mothers with this condition.

The Relationship between Abdominal Diastasis and Lumbar Pain Pressure Threshold in Women Who Have Given Birth between the Ages of 30 and 45 Years-An Observational Pilot Study

Background and Objectives: Current evidence confirms that the magnitude of the inter-rectus distance (IRD) is associated with the severity of abdominal pain. Furthermore, evidence exists in the literature about the impact abdominal muscles have on low back pain, lumbopelvic pain, breathing and lumbar abdominal strength; however, no studies analysing the level of association between abdominal diastasis and lumbar pain pressure threshold (PPT) exist. The aim of this study was to analyse the level of association between the rectus abdominis distance and pain pressure threshold in the lumbar spinous processes in women who have given birth between the ages of 30 and 45 years. Secondly, it was to study the level of association between the time elapsed since the last delivery and low back pain in women who have given birth between 30 and 45 years of age. Material and Methods: This was a pilot observational study in which 21 females participated. The abdominal diastasis was measured by ultrasound, the pain pressure threshold was assessed by an algometer and the pain perception by the Mc Gill questionnaire. Results: There was no significant relationship between increased abdominal distance and increased lumbopelvic pain in women who gave birth between the ages of 30 and 45 years. However, there was a correlation between the time that had elapsed since the last delivery and low back pain. Conclusions: there was a correlation between the time that had elapsed since the last delivery and low back pain. Further studies analysing factors that may perpetuate the chronicity of symptoms, such as lifestyle and intrinsic factors, are needed.

The Impact of Exercising on Pelvic Symptom Severity, Pelvic Floor Muscle Strength, and Diastasis Recti Abdominis After Pregnancy: A Longitudinal Prospective Cohort Study

OBJECTIVE

The objective of this study was to evaluate whether early postpartum exercise is associated with changes in pelvic symptom severity, pelvic floor muscle strength, and diastasis recti abdominis (DRA) from 3 to 12 months postpartum.

METHODS

In this prospective cohort study, 504 participants with and without pelvic symptoms (pelvic girdle pain, stress urinary incontinence, vaginal heaviness) were followed. At 3, 6, 9, and 12 months postpartum, we assessed pelvic symptoms, exercise behavior (by questionnaires), pelvic floor muscle strength (by vaginal palpation), and DRA (by caliper measurement). Based on the 3-months questionnaire, participants were categorized as nonexercisers (n = 105), minimal low-impact exercisers (n = 249), regular low-impact exercisers (n = 117), and high-impact exercisers (n = 32). Between-group differences and within-group changes from 3 to 12 months were calculated using Chi-square tests, Kruskal-Wallis tests, and Friedman analysis of variance.

RESULTS

At 3 months, no differences in symptom prevalence were seen between the groups. Nonexercisers reported higher pelvic girdle pain severity and had weaker pelvic floor muscles. The within-group analysis showed that pelvic girdle pain severity did not change in nonexercisers or high-impact exercisers, but decreased in minimal and regular low-impact exercisers. Stress urinary incontinence increased in nonexercisers from 3 to 12 months, while it remained unchanged in regular low-impact and high-impact exercisers, and decreased in minimal low-impact exercisers. Across all groups, vaginal heaviness and DRA decreased, and pelvic floor strength increased from 3 to 12 months.

CONCLUSION

The study indicates that early low-impact exercising is associated with reduced pelvic girdle pain severity during the first postpartum year. Minimal low-impact exercisers also showed a slight reduction in stress urinary incontinence. Conversely, nonexercisers reported an increase in stress urinary incontinence between 3 and 12 months postpartum.

IMPACT

Physical therapists should encourage women to start with low-impact exercise early after pregnancy.

LAY SUMMARY

This study highlights the positive effects of starting gentle, low-impact exercise early after childbirth to reduce pelvic girdle pain and urinary incontinence.

Pregnant women may exercise both abdominal and pelvic floor muscles during pregnancy without increasing the diastasis recti abdominis: a randomised trial

QUESTION

What is the effect of a 12-week abdominal and pelvic floor muscle exercise program during pregnancy on the inter-recti distance (IRD) in women with diastasis recti abdominis immediately after the 12-week intervention period and at follow-up 6 weeks postpartum?

DESIGN

An exploratory, parallel-group, randomised controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis.

PARTICIPANTS

Ninety-six pregnant women aged ≥ 18 years, either primigravida or multigravida, in gestation week 24 with an IRD of ≥ 28 mm measured at rest and/or a protrusion on initial assessment.

INTERVENTION

The experimental group participated in a 12-week abdominal and pelvic floor muscle exercise program during pregnancy. The control group received no intervention.

OUTCOME MEASURES

Change (mm) in IRD 2 cm above and below the umbilicus at rest from pre-intervention to immediately post-intervention and to 6 weeks follow-up measured with ultrasonography.

RESULTS

The IRD increased for both groups from baseline to immediately after the intervention and decreased from after the intervention to the follow-up at 6 weeks postpartum. The IRD was smallest for both groups at the follow-up. At 2 cm above the umbilicus, the intervention effect was 2 mm (95% CI -2 to 7) immediately after the intervention and -1 mm (95% CI -4 to 3) at follow-up. At 2 cm below the umbilicus, the intervention effect was -5 mm (95% CI -10 to 0) immediately after the intervention and 0 mm (95% CI -4 to 4) at follow-up.

CONCLUSION

Abdominal and pelvic floor muscle training during pregnancy have a negligible effect on the IRD immediately after 12 weeks of intervention and at 6 weeks post-partum.

Clinical and exercise professional opinion of return-to-running readiness after childbirth: an international Delphi study and consensus statement

Female athletes have identified a lack of guidance as a barrier to successfully returning to running postpartum, and existing guidelines are vague. Our aim was to define the current practice of determining postpartum run-readiness through a consensus survey of international clinicians and exercise professionals in postpartum exercise to assist clinicians and inform sport policy changes.A three-round Delphi approach was used to gain international consensus from clinicians and exercise professionals on run-readiness postpartum. Professionals who work with postpartum runners participated in an online survey to answer open-ended questions about the following postpartum return-to-running topics: definitions (runner and postpartum), key biopsychosocial milestones that runners need to meet, recommended screening, timeline to initiate running, support items, education topics and factors that contribute to advising against running. Consensus was defined as ≥75% participant agreement.One hundred and eighteen professionals participated in round I, 107 participated in round II (response rate 90.6%) and 95 participated in round III (response rate 80.5%). Responses indicated that, following a minimum 3-week period of rest and recovery, an individualised timeline and gradual return to running progression can be considered. Screening for medical and psychological concerns, current physical capacity, and prior training history is recommended prior to a return to running.This study proposes recommendations for the initial guidance on return-to-running postpartum, framed in the context of current research and consensus from professionals. Future research is needed to strengthen and validate specific recommendations and develop guidelines for best practice when returning-to-running after childbirth.

Diastasis Recti Abdominis Rehabilitation in the Postpartum Period: A Scoping Review of Current Clinical Practice

INTRODUCTION AND HYPOTHESIS

Despite exercise being the standard approach to diastasis recti abdominis (DRA) rehabilitation, there is no consensus on the most effective exercise routine and adjunct modalities for reducing DRA and improving functional parameters. The present study is aimed at investigating evidence for DRA rehabilitation in postpartum women, as well as knowledge gaps and areas for future research.

METHODS

For this scoping review a systematic search was conducted in MEDLINE, AMED, CINAHL, Embase, ScienceDirect, Scopus, and PEDro up to November 2022. Selection criteria included studies investigating exercise therapy interventions both with and without adjunct modalities for postpartum DRA. Sample characteristics, diagnostic criteria, program design, and outcome measures were recorded. Critical appraisal of clinical trials was performed using PEDro classification.

RESULTS

Twenty-eight studies were included: 14 clinical trials, 3 case series, and 11 observational studies. DRA exercises that focused on deep and superficial muscles, pelvic floor muscles, respiratory maneuvers, functional exercises, or alternative interventions (yoga, suspension training, hypopressive exercise) and adjunct modalities showed promising results in reducing the inter-recti distance and related dysfunction. However, there was great variability in diagnostic criteria and methods, DRA severity, time post-birth, and exercise program design.

CONCLUSIONS

Reviewed studies provide valuable insights into exercise therapy, but it is important to recognize their limitations, as variability in diagnostic criteria, sample characteristics, and exercise program design hinder the generalizability of the findings. Further high-quality research is needed to strengthen the evidence in this area and provide reliable recommendations for clinical practice.

Prevalence of lumbopelvic pain during pregnancy: A systematic review and meta-analysis of cross-sectional studies

INTRODUCTION

Lumbopelvic pain (LPP) is common in pregnant women and has a significant negative effect on physical and psychological health. In this study, for the first time, we conduct a meta-analysis to estimate the overall prevalence of LPP among pregnant women and clarify the reasons for the differences in the estimated results.

MATERIAL AND METHODS

A systematic search of four databases (PubMed, Embase, Web of Science and Cochrane Central Register of Controlled Trials) was conducted from inception until October 2022. Two reviewers conducted a methodological quality assessment. Random-effects model analysis was used to estimate the pooled prevalence and the 95% confidence interval. Chi-square tests and I2 -values were used to assess the heterogeneity. Subgroup analysis (according to the participants' continent, age, body mass index [BMI], gestational age and study risk of bias), sensitivity analysis and random-effects meta-regression were used to explore the the sources of heterogeneity.

RESULTS

Of the 1661 unique citations, 38 studies (21 533 pregnant participants) were included in this systematic review and meta-analysis. The overall pooled prevalence of LPP during pregnancy was 63% (95% CI: 0.57 to 0.69), with significant heterogeneity (I2  = 99.1%, P < 0.001). The prevalence differed by participants' continents, 71% (North America), 74% (South America), 63% (Asia), 64% (Europe), 59% (Africa) and 45% (Oceania). The prevalence differed by BMI, 64% (BMI <25), 64% (25 ≤ BMI ≤ 28), and 71% (BMI >28). The prevalence differed by age, 72% (age <25 years), 58% (25 ≤ age ≤ 30 years), and 69% (age >30 years). The prevalence were the same differed by study risk of bias, 63% (both low and moderate risk of bias studies). The prevalence were similar by gestational age, 62% (second trimester) and 63% (third trimester).

CONCLUSIONS

Lumbopelvic pain during pregnancy is common; about three-fifths of pregnant women experience LPP. More prevention and intervention research for lumbopelvic should be conducted in pregnant women with different clinical characteristics.

Predictive Factors for Pregnancy-Related Persistent Pelvic Girdle Pain (PPGP): A Systematic Review

Background and Objectives: To identify the most frequently reported predictive factors for the persistency of pregnancy-related pelvic girdle pain (PPGP) at 3-6 months after childbirth in women with PPGP alone or PPGP in association with pregnancy-related lower back pain (PLBP). Methods: Eligibility criteria: Two authors independently selected studies excluding PPGP determined by a specific, traumatic, gynecological/urological cause or isolated PLBP and studies that did not include the presence/absence of PPGP as the the primary outcome. We, instead, included studies with an initial assessment in pregnancy (within 1 month of delivery) and with a follow-up of at least 3 months after delivery. Data sources: The research was performed using the databases of Medline, Cochrane, Pedro, Scopus, Web of Science and Cinahl from December 2018 to January 2022, following the indications of the PRISMA statement 2021 and the MOOSE checklist. It includes observational cohort studies in which data were often collected through prospective questionnaires (all in English). Study appraisal and risk of bias: Two independent authors performed evaluations of the risk of bias (ROB) using the quality in prognostic studies (QUIPS) tool. Synthesis of results: An in-depth qualitative analysis was conducted because, due to a high degree of heterogeneity in the data collection of the included studies and a lack of raw data suitable for quantitative analysis, it was not possible to carry out the originally planned meta-analyses for the subgroups. Results: The research process led to the inclusion of 10 articles which were evaluated using the QUIPS tool: 5 studies were evaluated as low ROB and 5 were evaluated as moderate ROB. High levels of pain in pregnancy, a large number of positive provocation tests, a history of lower back pain and lumbo-pelvic pain, high levels of disability in pregnancy, neurotic behavior and high levels of fear-avoidance belief were identified as strong predictors of long-term PPGP, while there was weak or contradictory evidence regarding predictions of emotional distress, catastrophizing and sleep disturbances. Discussion: The impossibility of carrying out the meta-analysis by subgroups suggests the need for further research with greater methodological rigor in the acquisition of measures based on an already existing PPGP core predictors/outcome sets.

Effect of exercise on the inter-rectus distance in pregnant women with diastasis recti abdominis: an experimental longitudinal study

OBJECTIVE

To investigate the effect of acute contraction of the pelvic floor muscles (PFM) and abdominal exercises on the inter-rectus distance (IRD) compared to resting values, and differences between gestation weeks 27 and 37, in pregnant women with diastasis recti abdominis (DRA).

DESIGN

Experimental longitudinal design.

SETTING

Physiotherapy clinic, primary health care.

PARTICIPANTS

Thirty-eight pregnant women with DRA ≥ 2.8 cm.

INTERVENTIONS

Two-dimensional ultrasound images of IRD 2 cm above and below the umbilicus were taken at rest and during PFM and abdominal exercises at gestation week 27 and 37. Repeated measures analyses of variance (ANOVAs) with post hoc tests was performed for each exercise for both locations and timepoints.

MAIN OUTCOME MEASURES

Change in IRD.

RESULTS

There was a mean increase of the IRD from rest during a PFM contraction (2 mm, 95% CI: 2, 3), drawing-in (4 mm, 95% CI: 3, 5) and a combination of these (5 mm, 95% CI: 4, 6) There was a mean decrease of the IRD from rest during the headlift (-3 mm, 95% CI: -4, -2), the curl-up (-3 mm, 95% CI: -4, -2) and the diagonal curl up (-4 mm, 95% CI: -5, -3). Effect of time from gestation week 27-37 was a mean increase of 8 mm (95% CI: 6, 9).

CONCLUSION

Pelvic floor and drawing-in exercise increased the IRD, whilst headlift, curl up and diagonal curl up decreased the IRD in pregnant women with DRA at gestation week 27 and 37. CONTRIBUTION OF THE PAPER.

Gestational diabetes mellitus and pelvic floor function 6 weeks postpartum in Chinese women

INTRODUCTION AND HYPOTHESIS

With the significant increase in its incidence, gestational diabetes mellitus (GDM) has received growing attention for its effect on pelvic floor function. This study was aimed at investigating the association of GDM with pelvic floor function and diastasis recti abdominis (DRA) in postpartum women.

METHODS

This is a retrospective cohort study. At 6 weeks postpartum, 1,133 postpartum women with vaginal delivery underwent routine examinations including measurement of the pelvic floor muscle (PFM) strength and endurance, determination of the stress urinary incontinence (SUI) by questionnaire, quantification of pelvic organ prolapse (POP) and assessment of DRA. Statistical analysis was performed using binary logistic regression and multiple linear regression analysis.

RESULTS

One hundred and seventy-six (176) of the 1,133 women were confirmed to be suffering from GDM, with a rate of 15.53% (176 out of 1,133). The age and pre-pregnancy body mass index of the GDM group were significantly higher than those without GDM (p < 0.05). The GDM group was more likely to have smaller gestational age and a higher chance of having to undergo a lateral episiotomy. No statistically significant differences are found in PFM endurance (B: -0.025, p = 0.462) or PFM strength (B: -0.001, p = 0.979) between women with and without GDM. And these two groups are not significantly different in terms of the prevalence of SUI (19.3% vs 20.4%), POP (35.8% vs 37.5%) and DRA (29.0% vs 25.8%; p > 0.05).

CONCLUSIONS

Pelvic floor muscle function and SUI/POP/DRA prevalence of women at 6 weeks postpartum are not significantly affected by GDM.

Curl-up exercises improve abdominal muscle strength without worsening inter-recti distance in women with diastasis recti abdominis postpartum: a randomised controlled trial

QUESTION

What is the effect of a 12-week, home-based, abdominal exercise program containing head lifts and abdominal curl-ups on inter-recti distance (IRD) in women with diastasis recti abdominis (DRA) 6 to 12 months postpartum? What is the effect of the program on: observed abdominal movement during a curl-up; global perceived change; rectus abdominis thickness; abdominal muscle strength and endurance; pelvic floor disorders; and low back, pelvic girdle and abdominal pain?

DESIGN

This was a two-arm, parallel-group, randomised controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis.

PARTICIPANTS

Seventy primiparous or multiparous women 6 to 12 months postpartum, having a single or multiple pregnancy following any mode of delivery, with a diagnosis of DRA (IRD > 28 mm at rest or > 25 mm during a curl-up).

INTERVENTION

The experimental group was prescribed a 12-week standardised exercise program including head lifts, abdominal curl-ups and twisted abdominal curl-ups 5 days a week. The control group received no intervention.

OUTCOME MEASURES

The primary outcome measure was change in IRD measured with ultrasonography. Secondary outcomes were: observed abdominal movement during a curl-up; global perceived change; rectus abdominis thickness; abdominal muscle strength and endurance; pelvic floor disorders; and low back, pelvic girdle and abdominal pain.

RESULTS

The exercise program did not improve or worsen IRD (eg, MD 1 mm at rest 2 cm above the umbilicus, 95% CI -1 to 4). The program improved rectus abdominis thickness (MD 0.7 mm, 95% CI 0.1 to 1.3) and strength (MD 9 Nm, 95% CI 3 to 16) at 10 deg; its effects on other secondary outcomes were trivial or unclear.

CONCLUSION

An exercise program containing curl-ups for women with DRA did not worsen IRD or change the severity of pelvic floor disorders or low back, pelvic girdle or abdominal pain, but it did increase abdominal muscle strength and thickness.

Is Diastasis Recti Abdominis Associated With Low Back Pain? A Systematic Review

BACKGROUND

Low back pain (LBP) is a common cause of disability worldwide; multiple causes and risk factors have been proposed in the genesis of back pain. Some studies reported an association between diastasis recti abdominis (DRA), a surrogate for decreased core strength muscle, and low back pain. We aimed to investigate the relationship between DRA and LBP through a systematic review.

METHODS

A systematic review of the literature of clinical studies in English literature was conducted. PubMed, Cochrane, and Embase databases were used to conduct the search up to January 2022. The strategy included the following keywords: "Lower Back Pain" AND "Diastasis Recti" OR "Rectus abdominis" OR "abdominal wall" OR "paraspinal musculature".

RESULTS

From 207 records initially found, 34 were suitable for full review. Thirteen studies were finally included in this review, with a total of 2,820 patients. Five studies found a positive association between DRA and LBP (5 of 13 = 38.5%) whereas 8 studies did not find any association between DRA and LBP (8 of 13 = 61.5%).

CONCLUSIONS

Of the studies included in this systematic review, 61.5% did not find an association between DRA and LBP whereas a positive correlation was observed in 38.5% of studies included. Based on the quality of the studies included in our review, better studies are warranted to understand the association between DRA and LBP.

The "Mother Load" and Return to Sport: A Case Report of Returning to Professional Netball Following Cesarean Section

Background

Increasing numbers of elite female athletes are competing in professional sport, and many wish to become pregnant and return to competitive sport after childbirth. Athletes have a higher risk of pelvic floor dysfunction (PFD) than non-athletes (54% versus 7%) and there is also an increased prevalence in post-partum women compared to nulliparous women (35% versus 2.8-7.9%). Additionally, PFD has been shown to influence athletic performance. High quality evidence for elite athletes is lacking, and there are no exercise guidelines specifically for these women to prepare or effectively guide their safe return to sport (RTS). The purpose of this case report is to detail the management of an elite athlete who presented following cesarean section (CS) with the goal of RTS within 16 weeks.

Case Description

A 27-year-old primiparous Caucasian professional netballer presented at four weeks post- caesarean section (CS) for RTS screening and assessment of pelvic floor muscle (PFM) function. Assessment included readiness and fear of movement screening, dynamic pelvic floor muscle function, structural integrity of the CS wound, levator hiatal dimensions, bladder neck descent, and early global neuromuscular screening. Measures were collected at four weeks, eight weeks, and six months post-partum. The post-partum athlete demonstrated alterations in pelvic floor muscle function, reduced lower limb power and psychological readiness. A functionally staged dynamic and sport specific pelvic floor muscle training program was implemented and adapted to the patient for her early post-partum timeline.

Results

Rehabilitation strategies were effective in achieving the primary outcome of RTS at 16 weeks post-partum with no adverse events reported at 6 months follow-up.

Discussion

This case highlights the need for a holistic and individualised RTS management approach that includes women's and pelvic health risk factors in a professional athlete.

Can Clinical Postpartum Muscle Assessment Help Predict the Severity of Postpartum Pelvic Girdle Pain? A Prospective Cohort Study

OBJECTIVE

The purpose of this study was to evaluate whether the clinical assessment of pelvic floor muscles and the diastasis recti abdominis could predict the severity of pelvic girdle pain during the first year postpartum.

METHODS

Between 2018 and 2020, 504 women were recruited to this prospective longitudinal cohort study. At 2 to 3 months postpartum, their pelvic floor muscles and diastasis recti abdominis were assessed using vaginal palpation, observation, and caliper measurement. The participants completed the Pelvic Girdle Questionnaire (PGQ) at 2 to 3, 6, 9, and 12 months postpartum. Mixed-effect models were used to determine how the results of pelvic floor muscle and diastasis recti abdominis assessments predicted the PGQ score. A sub-analysis for middle to high PGQ scores was conducted.

RESULTS

Maximal voluntary pelvic floor muscle contractions ≥3 (Modified Oxford Scale, scored from 0 to 5) predicted a decreased PGQ score (β = -3.13 [95% CI = -5.77 to -0.48]) at 2 to 3 months postpartum, with a higher prediction of a middle to high PGQ score (β = -6.39). Diastasis recti abdominis width did not have any significant correlation with the PGQ score. A sub-analysis showed that a diastasis recti abdominis width ≥35 mm predicted an increased PGQ score (β = 5.38 [95% CI = 1.21 to 9.55]) in women with pelvic girdle pain.

CONCLUSION

The distinction between weak and strong maximal voluntary pelvic floor muscle contractions is an important clinical assessment in women with postpartum pelvic girdle pain. The exact diastasis recti abdominis width, measured in millimeters, showed no clinical relevance. However, a diastasis recti abdominis width ≥35 mm was associated with a higher PGQ score, and further research about this cutoff point in relation to pain is needed.

IMPACT

This study highlights the importance of clinical assessment of pelvic floor muscles in patients with postpartum pelvic girdle pain. A better understanding of the role of this muscle group will enable more effective physical therapist treatment of pelvic girdle pain.

Correlation of Percentage Body Fat, Waist Circumference and Waist-to-Hip Ratio with Abdominal Muscle Strength

Sedentary lifestyle and consumption of high-fat foods have become widespread, especially in the urban population. This leads to a reduction in lean body mass and increased body fat. The correlation between body fat indices and low back pain has been less explored and documented. The aim of this study was to identify the correlation between the percentage of body fat, waist circumference and waist-to-hip ratio and abdominal muscle strength. Percentage of body fat was estimated by using the body composition analyzer method using Tanita BC-545 Innerscan Segmental Body Composition. Waist-to-hip ratio was calculated by dividing the waist circumference by hip circumference. Abdominal muscle (rectus abdominis and external oblique) strength was measured by maximum voluntary isometric contraction as measured by surface electromyography. A positive correlation was observed between waist circumference and the percentage of body fat, while a negative correlation was observed between the average maximum voluntary isometric contraction of rectus abdominis and external oblique muscles and the percentage of body fat. Individuals with a high percentage of body fat tend to have higher fat distribution over the abdominal region and decreased abdominal muscle strength. Therapists should emphasize the use of abdominal muscles in individuals with high body fat in order to reduce the associated risk of the development of poor posture and low back pain.

Efficacy of electro-acupuncture in postpartum with diastasis recti abdominis: A randomized controlled clinical trial

Background

Electro-acupuncture (EA) has promising effects on diastasis rectus abdominis (DRA), defined as a separation of the two muscle bellies of rectus abdominis. To study, there is scant knowledge or scarce high-quality evidence.

Objective

We aimed to evaluate the long-term efficacy and safety of EA in treating DRA during postpartum. It was assumed that the improvement of DRA was more obvious in the EA group than in the control group.

Design

Randomized, controlled, blinded trial (Clinical Trial Registration: ChiCTR2100041891).

Setting

Hangzhou Hospital of Traditional Chinese Medicine in China.

Participants

Females aged 20-45 years without a past medical history of pathological rectus abdominal dissection were recruited from DRA inclusion criteria from 42 days to 1 year postpartum.

Intervention

110 participants were randomly assigned in a 1:1 ratio to a control group with no EA intervention (n = 55), and EA group (n = 55). The EA group received ten sessions of EA combined with physical exercise or only physical exercise for 2 weeks with a 26-week follow-up.

Measurements

Outcomes were assessed at baseline, week 2, and week 26. The primary outcome was the change of the inter recti distance (IRD) and electromyographic evaluation of the pelvic floor. Secondary outcomes included elasticity of linea alba (LA), paraumbilical subcutaneous adipose tissue (SAT) measurement, body mass index (BMI), percentage body fat (F%), dyspepsia symptoms, menstrual symptoms, quality of life (QoL), pain performance of patients with lower back pain, postnatal depression symptoms (PDS), postpartum self-image, and DRA-related symptom assessment including urine leakage, frequency, and urgency, constipation, sexual dysfunction, and chronic pelvic pain.

Results

A total of 110 maternal (55 in each group) were recruited. The mean difference in IRD from baseline to week 2 and week 26 in all states of the two groups were reduced compared with those before treatment, with statistical significance (P < 0.05). The mean of IRD at the horizontal line of the umbilicus in the end-expiratory state was smaller in the EA group than in the control group, but the difference was not statistically significant (P > 0.05) at week 2. The mean of IRD at the horizontal line of the umbilicus in head-up and flexed knee state was smaller in the EA group than in the control group, and the difference was statistically significant (P < 0.05) at week 26. Five (9.1%) and thirteen (23.64%) adverse events were reported in EA and control groups, respectively. No serious adverse events were reported.

Limitation

The frequency intensity of EA parameters was selected between 4 and 6 because of individual tolerance differences.

Conclusion

EA is an effective approach to improve IRD, electromyographic evaluation of the pelvic floor, BMI, the elasticity of LA, paraumbilical SAT, and symptoms of DRA, with durable effects at 26 weeks.

Primiparous women's knowledge of diastasis recti abdominis, concerns about abdominal appearance, treatments, and perceived abdominal muscle strength 6-8 months postpartum. A cross sectional comparison study

BACKGROUND

Diastasis recti abdominis (DRA) is a prevalent condition in the postpartum period. To date, there is scant knowledge on how DRA influences physical, mental, and emotional health. This study investigates primiparous women`s knowledge about DRA, concerns about abdominal appearance, and perceived abdominal muscle strength, comparing women with and without reported DRA.

METHODS

This was a cross-sectional comparison study. Data were collected by a web-based questionnaire, mainly through social media in Norway. To be included in the study women had to be primiparous 6-8 months postpartum. The questionnaire contained questions regarding women`s knowledge about DRA, perceived protrusion, received treatment, concerns with abdominal appearance and muscle strength. Abdominal body image was measured through the shape concern questions from The Eating Disorder Examination questionnaire (EDE-Q 6.0). Demographic and other descriptive variables are presented as means with standard deviations (SD) or as frequencies with percentages. Chi-square test of independence and independent sample t-tests were used to compare differences between women with and without abdominal protrusion for categorical and continuous variables, respectively.

RESULTS

Our sample consisted of 460 women. Knowledge about DRA was reported by 415/440 (94.3%) women. A total of 73.3% reported to have been worried during pregnancy about abdominal appearance postpartum. Mean degree of concern about present abdominal appearance was 5.5/10 (SD 2.4). Almost 80% experienced weaker abdominal muscles than pre-pregnancy. Ninety-six women (20.9%) reported a protrusion along the midline of their abdomen. Significantly more women with protrusion reported weaker abdominal muscles than women without protrusion. The most frequent treatment women with protrusion reported were exercises for the abdominal muscles (92.6%). Mean score on the EDE-Q, shape concern questions, was higher in women with reported protrusion (mean score: 2.37 (SD 1.6) than women without protrusion (mean score: 2.14 (SD 1.4), p = 0.175.

CONCLUSION

Primiparous women are concerned about abdominal appearance both during pregnancy and after birth. Those reporting abdominal protrusion are less satisfied with their abdominal appearance and they report weaker abdominal muscles than women without protrusion. This study may contribute to improved knowledge about women`s health concerns, and assessment of DRA should be part of routine follow-up of postpartum women.

The Association between Postpartum Pelvic Girdle Pain and Pelvic Floor Muscle Function, Diastasis Recti and Psychological Factors-A Matched Case-Control Study

There is uncertainty regarding the association between abdominal morphology, pelvic floor function, and psychological factors in women with postpartum pelvic girdle pain (PGP). The aim of this case-control study was to evaluate the differences between women with and without persistent PGP regarding pelvic floor function, diastasis recti, and psychological factors 6−24 weeks postpartum. Pelvic floor manometry, palpation examination of abdominal muscles, the International Consultation on Incontinence Questionnaire Short Form, The Depression, Anxiety and Stress Scale—21, and the Pain Catastrophizing Scale were used. The PGP group presented with lower vaginal resting pressure (p < 0.001), more tenderness (p = 0.018) and impaired voluntary activation of pelvic floor muscles (p ≤ 0.001). Women with pain also had more distortion on the level of the anterior abdominal wall (p = 0.001) and more severe diastasis recti (p = 0.046) when compared to pain-free controls. Lower vaginal resting pressure was the strongest factor explaining PGP (OR 0.702, 95%CI 0.502−0.981). There were no differences in terms of the pelvic floor strength, endurance, severity of urinary incontinence and reported distress between the groups. Women with PGP 6−24 weeks postpartum differ in pelvic floor and abdominal muscle function from the pain-free controls. Vaginal resting pressure may be an important factor in pelvic girdle pain shortly postpartum. Further studies are needed to see a trend in changes over time.

Physical Therapy Is an Important Component of Postpartum Care in the Fourth Trimester

ABSTRACT

The objectives of this Perspective paper are to educate physical therapists on their important role in assessing and treating common pregnancy- and delivery-related health conditions and to advocate for their routine inclusion in postpartum care during the fourth trimester. Pelvic floor dysfunction (PFD) and diastasis recti abdominis (DRA) are 2 examples of musculoskeletal disorders associated with pregnancy and childbirth that can have negative physical, social, and psychological consequences. This paper reviews evidence from 2010 through 2021 to discuss the efficacy of physical therapist intervention in the fourth trimester for PFD and DRA. The role of physical therapy in the United States is compared with its role in other developed nations, with the intent of illustrating the potential importance of physical therapy in postpartum care. Evidence shows physical therapy is an effective, low-risk, therapeutic approach for PFD and DRA; however, physical therapists in the United States currently have a peripheral role in providing postpartum care. Lack of awareness, social stigma, and policy barriers prevent women from receiving physical therapist care. Recommendations are made regarding ways in which physical therapists can increase their involvement in the fourth trimester within their community, stimulate policy change, and promote improved postpartum care practices.

IMPACT

This Perspective highlights the valuable role of physical therapist assessment and treatment during the postpartum period for some common musculoskeletal conditions associated with pregnancy and delivery.

Association Among Pelvic Girdle Pain, Diastasis Recti Abdominis, Pubic Symphysis Width, and Pain Catastrophizing: A Matched Case-Control Study

OBJECTIVE

Pregnancy-related pelvic girdle pain (PGP) may persist or occur postpartum and negatively affects women's lives. There is uncertainty regarding the association between the structures of the bony pelvis, diastasis recti abdominis (DRA), pain processing, and PGP and to what extent these factors should be considered during physical therapy. This study aimed to evaluate the differences between women with and without PGP shortly after delivery regarding the separation of a pubic symphysis, DRA, and pain catastrophizing.

METHODS

Women diagnosed with PGP 24 to 72 hours after vaginal delivery were matched to pain-free controls according to age and parity. Ultrasound evaluations of diastasis recti (interrecti distance [IRD]) during rest and curl-up task and pubic symphysis (interpubic width) were performed. The Pain Catastrophizing Scale was used to assess the level of catastrophizing. A special Cox regression model was used to fit a conditional logistic regression for a 1:2 matched case-control study.

RESULTS

Thirty-five women with clinically diagnosed PGP and 70 matched controls were included in the study. The PGP group had a significantly higher pre-pregnancy body mass index than the control group. After adjusting for body mass index in multiple conditional logistic regression, the interpubic distance (odds ratio = 1.64; 95% CI = 1.22 to 2.20) and IRD during curl-up (odds ratio = 2.01; 95% CI = 1.08 to 3.74) were significantly associated with PGP. Pain catastrophizing and IRD at rest were not associated with PGP in univariable or multivariable analysis.

CONCLUSIONS

Pain catastrophizing is similar for women with and without PGP early postpartum. However, the degree of the pubic symphysis and rectus abdominis separation during the curl-up task are positively associated with PGP shortly after delivery.

IMPACT

This study indicates that a reconsideration of the way we look at DRA is warranted. The development of a more comprehensive assessment including objective measurements and a biopsychosocial understanding is needed to inform directions for further postpartum physical therapy.

Efficacy of Acupuncture in Post-partum With Diastasis Recti Abdominis: A Randomized Controlled Clinical Trial Study Protocol

Background: Diastasis rectus abdominis (DRA) is one of the common complications during pregnancy and post-partum, which has psychological and physical effects on post-partum women. Acupuncture, a worldwide alternative therapy, has attracted wide attention in preventing and treating diseases related to pregnancy and childbirth. This study aims to evaluate the efficacy of acupuncture combined with physical training in treating post-partum rectus muscle dissociation.

Methods: This is a randomized, controlled trial of DRA in post-partum conducted at Hangzhou Hospital of Traditional Chinese Medicine Affiliated with Zhejiang University of Chinese Medicine. The primary purpose is to evaluate the effectiveness of acupuncture and physical training on DRA in post-partum women. The study will be conducted from March 2022 to March 2023. The acupuncture group received acupuncture and physical training (n = 48), the sham acupuncture group received sham acupuncture and physical training (n = 48), and the physical training group received physical training (n = 48). These experiments perform once/day, five times a week for 2 weeks, followed up for half a year after the end of the course of treatment. Our tests perform a course of treatment, which includes a total of 10 consecutive treatments. Furthermore, the patient will be followed up for half a year after the treatment. Primary and secondary indicators, including inter recti distance (IRD), linea alba (LA) tension, the MOS item short-form health survey (SF-36), short-form McGill pain questionnaire-2 (SF-MPQ-2), body mass index (BMI), waist-to-hip ratio (WHR), leeds dyspepsia questionnaire (LDQ), menstrual distress questionnaire (MDQ), 10 items of edinburgh post-natal depression scale (EPDS-10), the modified body self-image scale (MBIS), international consultation incontinence questionnaire short-form (ICIQ-SF) and hernia-related quality-of-life survey (HerQles), which will be evaluated before and after treatment and half a year after treatment. Adverse events and side effects during each treatment will be collected and recorded.

Discussion: There is evidence that acupuncture and physical training can treat DRA in post-partum. In this study, we evaluate the effectiveness of acupuncture in post-partum with DRA.
