A Research Study Exploring How Musculoskeletal Function and the Autonomic Nervous System Relate to Visceral Pain in Women With and Without Dysmenorrhea (Painful Periods).
The Effect of Vaginal Somatovisceral Pain on Hip Extension Mobility and Strength in Women at Mid-cycle With Dysmenorrhea vs. Controls: A Case-control Study
Who can join
Ages 18 to 35 · Women · Healthy volunteers welcome
Full eligibility criteria
Inclusion Criteria: Non-pregnant women, not taking hormonal birth control, between the ages of 18 and 36 who report regular menstrual cycles are eligible for the study Exclusion Criteria: Participants will be excluded if they are currently pregnant or, have given birth within the preceding six months, are breastfeeding, or are undergoing in-vitro fertilization treatments. Exclusions also include those who have had abdominal, lumbar, or pelvic surgery within the preceding 12 months, suffer from a chronic pain condition, have an active genitourinary infection, are incontinent of bowel or bladder, or have been diagnosed with prolapse of a pelvic organ, severe labral pathology, femoral acetabular impingement (FAI), interstitial cystitis, endometriosis, pelvic inflammatory disease, irritable bowel syndrome, or other pelvic pathology. Participants reporting a cycle length of less than 28 days or longer than 35 days, those with a history of sexual assault, and those who are anovulatory without hormonal BC or amenorrheic will also be excluded. \-
About the study
The purpose of this clinical trial is to determine if women with dysmenorrhea demonstrate an increased musculoskeletal and autonomic nervous system response to a painful visceral stimulus compared to controls. A secondary aim is to determine if interoceptive awareness moderates this relationship. The designed methodology aims to elucidate the intricate connections between the interoceptive and musculoskeletal systems in pain perception among female participants, providing valuable insights into the underlying mechanisms of interoceptive pain and functional musculoskeletal changes.
