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.

Trajectories of pain intensity, pain catastrophizing, and pain interference in the perinatal and postpartum period

Introduction

Chronic pain (pain >3 months) is a growing epidemic. Normal pregnancy may give rise to recurrent and sometimes constant pain for women. Women with worse pain symptoms are more likely to report symptoms of anxiety, depression, and/or insomnia during the perinatal period, which may impact labor and delivery outcomes. We examined the relationship between demographic and psychological predictors of pain throughout pregnancy and into the postpartum.

Objectives

To examine trajectories of pain intensity, pain catastrophizing, and pain interference during pregnancy and the early postpartum, and associated sociodemographic predictors of trajectory membership.

Methods

One hundred forty-two pregnant women were assessed at 4 time points for measures of pain intensity, pain catastrophizing, pain interference, and symptoms of insomnia, depression, and generalized anxiety. Women completed the first survey before 20 weeks' gestation and were reassessed every 10 weeks. Surveys were completed on average at 15 weeks', 25 weeks', and 35 weeks' gestation, and at 6-week postpartum. Using latent class mixed models, trajectory analysis was used to determine trajectories of pain intensity, pain catastrophizing, and pain interference.

Results

A 1-class pain intensity model, 2-class pain catastrophizing model, and 3-class pain interference model were identified. Adaptive lasso and imputation demonstrated model robustness. Individual associations with trajectories included baseline symptoms of anxiety, depression, and insomnia, and pain symptomology.

Conclusion

These findings may help to identify women who are at high risk for experiencing pain symptoms during pregnancy and could aid in developing targeted management strategies to prevent mothers from developing chronic pain during their pregnancy and into the postpartum period.

Drivers, barriers, and response to care of Australian pregnant women seeking chiropractic care for low back and pelvic girdle pain: a qualitative case study

BACKGROUND

Pregnancy-related low back and/or pelvic girdle pain is common, with a prevalence rate of up to 86% in pregnant women. Although 19.5% of Australian pregnant women visit a chiropractor for pelvic girdle pain, little is known about the experience of pregnant women who seek this care. The aim of this study was to describe and explore the experiences of Australian pregnant women who seek chiropractic care for their current pregnancy-related low back and/or pelvic girdle pain.

METHODS

A qualitative case study approach with purposive sampling from 27 chiropractic practices was used. A grounded theory approach was informed by a constructivist and interpretivist stance, which provided understanding and meaning to the pregnant women's experiences. Online unstructured interviews were recorded, transcribed, and anonymised. A thematic analysis was subsequently conducted on the primary data. Codes and major themes were developed with the use of critical self- reflection (memos), survey finding triangulation and respondent validation.

RESULTS

Sixteen potential respondents expressed interest in participating. After eligibility screening and data saturation, nine interviews were undertaken. Four key themes were identified: "Care drivers: what drives care seeking?", "Care barriers: what barriers are encountered?", "Chiropractic treatment: what does treatment consist of?" and "Response to care: what response was there to care?".

CONCLUSION

Four key themes: care drivers, care barriers, chiropractic treatment, and response to care support an emergent substantive-level theory in women's care seeking experiences for pregnancy-related back pain and chiropractic care. This theory is that chiropractic care for pregnant women experiencing low back pain and pelvic girdle pain may improve pain and function, while reducing pregnancy-related biopsychosocial concerns. The findings may inform antenatal health providers and the chiropractic profession about pregnant women's experience seeking chiropractic care as well as directing future research.

Relationship Between Location of Pregnancy-Related and Postpartum-Related Back Pain and Limitations of Daily Activities and Work Participation

OBJECTIVE

The aims of this study were to (1) examine if the location of pregnancy-related back pain impacts activities of daily living and absence from work and (2) determine which types of pain were more likely to persist postpartum.

METHODS

This was a secondary analysis of data from an observational cohort study. Data were collected in Ontario between 2013 and 2014. Four pain location groups were identified, including low back pain (LBP), pelvic girdle pain (PGP), combined pain, and mixed pain. Logistic regression models were used to examine the impact of pain location on activity and absence from work. Descriptive analyses explored the association between pregnancy pain location and postpartum pain patterns.

RESULTS

We surveyed 305 pregnant participants and followed up with 80 of these participants up to 6 months postpartum. Data analysis showed approximately a 2-fold increase in interference with employment (outside the home) and self-grooming for those with combined pain compared to those only experiencing LBP. Respondents with PGP and combined PGP and LBP had approximately a 5-fold increased likelihood of absence from work compared to respondents with only LBP; those with a mixture of LBP and PGP had a 13-fold increase in likelihood. Approximately 50% of respondents reported being pain-free, 16% experienced lingering pain, and 38% experienced persistent pain within 6 months postpartum. Those with combined pain during pregnancy continued to have persistent pain up to 6 months postpartum.

CONCLUSION

The results suggest that the location of pregnancy-related back pain is associated with interference in daily activities, an increase in absence from work, and the persistence of postpartum pain. For this cohort, back pain did not always resolve after delivery, and those experiencing pregnancy-related combined pain continued to experience symptoms postpartum.

Validation of self-administered tests for screening for chronic pregnancy-related pelvic girdle pain

Background

Many women develop pelvic girdle pain (PGP) during pregnancy and about 10% have chronic pain several years after delivery. Self-administered pain provocation tests are one way to diagnose and evaluate this pain. Their validity in post-partum women is not yet studied.

The purpose of this study was to evaluate the validity of self-administered test for assessment of chronic pregnancy-related PGP several years after delivery.

Methods

Women who previously have had PGP during pregnancy and who participated in one of three RCT studies were invited to a postal follow up of symptoms including performance of self-administered tests after two, 6 or 11 years later, respectively. In total, 289 women returned the questionnaire and the test-results. Of these, a sub-group of 44 women with current PGP underwent an in-person clinical examination. Comparisons were made between test results in women with versus without PGP but also, in the sub-group, between the self-administered tests and those performed during the clinical examination.

Results

Fifty-one women reported PGP affecting daily life during the last 4 weeks, and 181 reported pain when performing at least one of the tests at home. Those with chronic PGP reported more positive tests (p < 0.001). There was no significant difference between diagnosis from the self-administered tests compared to tests performed during the in-person clinical examination (p = 0.305), either for anterior or posterior PGP. There were no significant differences of the results between the tests performed self-administered vs. during the clinical examination.

Conclusion

A battery of self-administered tests combined with for example additional specific questions or a pain-drawing can be used as a screening tool to diagnose chronic PGP years after delivery. However, the modified SLR test has limitations which makes its use questionable.
