Psychological distress and self-rated health status in reproductive aged women with pain: findings from a national, cross-sectional survey

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.

Association of coccygodynia with pelvic floor symptoms in women with pelvic pain

BACKGROUND

Coccygodynia is a painful condition of the tailbone that occurs more commonly in females. The association of coccyx pain with pelvic floor symptoms and the prevalence of coccyx pain in women with pelvic pain has not previously been reported.

OBJECTIVE

To identify the prevalence of coccygodynia in women with pelvic pain and to describe the association of coccygodynia with pelvic floor examination findings and symptoms.

DESIGN

Retrospective cohort analysis.

SETTING

Tertiary medical institution.

PARTICIPANTS

One hundred twenty-seven women presenting for outpatient pelvic floor physical therapy treatment who underwent vaginal and rectal pelvic floor examination.

MAIN OUTCOME MEASURES

Prevalence of coccygodynia, pain scores, association of coccygodynia with other comorbidities and diagnoses, and association of coccygodynia with physical examination findings.

RESULTS

Sixty-three (49.6%) of 127 women with pelvic pain presented with coccygodynia and 64 (50.4%) did not. Women with coccygodynia had significantly higher rates of muscle spasm (50.8% vs. 31.2%, p = .025) higher visual analog scale pain scores (median 5 vs. 3, p = .014), higher rates of outlet dysfunction constipation (31.7% vs. 10.0%, p = .032), and higher rates of fibromyalgia (15.9% vs. 3.1%, p = .014). On pelvic examination, women with coccygodynia were significantly more likely to have sacrococcygeal joint hypomobility (65.1% vs. 14.1%, p < .001), coccygeus muscle spasm (77.8% vs. 17.2%, p < .001), anococcygeal ligament pain (63.5% vs. 9.4%, p < .001), external anal sphincter pain/spasm (33.3% vs. 13.1%, p < .001), and impaired pelvic floor muscle coordination (77.8% vs. 57.8%, p = .016).

CONCLUSIONS

Almost 50% of women seeking pelvic floor physical therapy for pelvic pain had coexisting coccygodynia. These women had higher pain scores, increased pelvic floor dysfunction, and significantly greater abnormal physical exam findings. This study demonstrates a strong link between coccygodynia, pelvic floor symptoms, and pelvic pain and highlights the importance of screening for and identifying coccyx pain when evaluating women with pelvic pain.
