Musculoskeletal evaluation of the lower pelvic complex in women with endometriosis: A case-control study.

OBJECTIVE

Use clinical pain measurement tools to investigate and compare the prevalence of pelvic loin disoders in women with and without endometriosis.

STUDY DESIGN

Chronic pelvic pain (CPP) associated with endometriosis has diverse origins, including musculoskeletal factors. Musculoskeletal dysfunction in the pelvic region is theorized to result from sustained muscular contraction, triggered by altered visceral stimuli and adoption of antalgic postures, causing secondary damage to muscles, ligaments, and joints. CPP significantly impacts quality of life, relationships, sexuality, and mental health. However, limited data exists on musculoskeletal impacts of endometriosis and CPP. It was made a case-control study at Maternidade Escola Assis Chateaubriand from August 2017 to January 2021. Evaluated 71 women: 41 in endometriosis group (EG) and 30 in control group (CG). Data collection included sociodemographic questionnaires, musculoskeletal physiotherapeutic evaluations, pain mapping, pressure pain thresholds, kinesiophobia, and disability measurements. Statistical analysis was performed using Spearman's Rho test to determine correlations.

RESULTS

Mean age of participants was 31 years. EG exhibited lower pain threshold variations in lumbopelvic trigger points than CG (P < .05). Significant muscle flexibility differences between groups were observed; EG had reduced flexibility (P < .05). Most common pain areas were hypogastrium in EG (48.78 %) and left lumbar in CG (30 %). EG had higher kinesiophobia values (P = .009). There was a weak association between kinesiophobia-pressure threshold association observed in CG's lumbar pelvic region.

CONCLUSION

Women with Endometriosis and CPP exhibit higher prevalence of musculoskeletal disorder, lower pain thresholds, decreased lumbopelvic muscle range of motion, higher kinesiophobia scores, and increased disability indices with low back pain compared to healthy women.
