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

•Women with Endometriosis and CPP have more musculoskeletal disorders of the PLC than women without Endometriosis.•Women with Endometriosis and CPP have a lower pressure pain threshold than women without Endometriosis.•There is a decrease in the range of motion in the muscles of the PLC of women with Endometriosis compared to healthy women.•There is a higher score in the kinesiophobia questionnaire in the presence of low back pain.•There is a higher index of physical disability in the presence of low back pain. Use clinical pain measurement tools to investigate and compare the prevalence of pelvic loin disoders in women with and without endometriosis. 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. Mean age of participants was 31 years. EG exhibited lower pain threshold variations in lumbopelvic trigger points than CG (P
