Sensitization and myofascial trigger points in women with any history of endometriosis and chronic pelvic pain, and healthy volunteers

	Pain and current or prior history of endometrisois CPP-any-endo-history (N=23) n (%)	Pain and never history of endometriosis CPP-never-endo (N=6) n (%)	Healthy Volunteers (N=20) n (%)	P-value
Sensitization	20 (87%)	4 (67%)	3 (15%)	<0.001
Regional Allodynia	19 (83%)	4 (67%)	3 (15%)	<0.001
Regional Hyperalgesia	17 (74%)	4 (67%)	1 (5%)	<0.001
Lowered pressure-pain-threshold PPT of supraspinous ligament	11 (48%)	3 (50%)	1 (5%)	0.003
Myofascial-trigger-points TrPs	21 (91%)	6 (100%)	3 (15%)	<0.001
Lowered pressure-pain-threshold PPT of muscles	5 (22%)	0	0	0.018

P-values are from tests for trend comparing pain and current or prior history of endometriosis versus pain and never any history of endometriosis versus CPP-endo-now vs CPP-no-endo-now vs healthy volunteers.

Chronic pelvic pain with any endometriosis history CPP-any-endo-history comprises all women with any history of surgically-diagnosed endometriosis in the past or those diagnosed with endometriosis at the study laparoscopy

PPT = pressure pain threshold

Myofascial TrPs = myofascial trigger points
