INTRODUCTION: Peak alpha frequency (PAF), an electroencephalography measure, has gained interest due to its association to pain-related neural processes in both healthy and clinical populations. In healthy groups, PAF derived from the senso…

Approximately 1 in 4 women with chronic pelvic pain (CPP) report persistent pelvic pain after hysterectomy. Centralized symptoms-fatigue, multisite pain, and sleep disturbance, quantified using the Fibromyalgia Survey Score (FSS)-often co-o…

BACKGROUND: Despite widespread agreement that high-tone pelvic floor dysfunction is highly prevalent among women with pelvic pain, there is no consensus regarding standardized assessment strategy or diagnostic criteria. Furthermore, there a…

IMPORTANCE: Endometriosis is a chronic, estrogen-dependent, inflammatory disease defined by endometrial-like tissue (lesions) outside the uterine lining. It affects up to 10% of women worldwide, and 9 million women in the US, during reprodu…

We evaluated inflammatory markers among 389 surgically confirmed endometriosis cases and 505 controls from the Women's Health Study: From Adolescence to Adulthood (A2A) cohort. Participants reported dysmenorrhea, acyclic pelvic pain, dyspar…

OBJECTIVE: Nociplastic pain is pain primarily driven by the central nervous system and, unlike nociceptive pain conditions, is thought to be refractory to peripherally directed therapies. Nociplastic pain is also associated with hypersensit…

Chronic overlapping pain conditions (COPCs) refer to conditions that have similar central nervous system pathophysiologic mechanisms driving widespread pain as well as common comorbid symptoms such as fatigue and problems with sleep, memory…

Cover: The cover image is from the Clinical Article Validation of a simple body map to measure widespread pain in urologic chronic pelvic pain syndrome: A MAPP Research Network study by Clemens JQ, Locke K, Landis JR, et al. Neurourol Urody…

Background Dyspareunia and restriction of sexual activity are often reported by patients with chronic pelvic pain, but less is known about which conditions or factors contribute most to these symptoms. Methods This is a cross-sectional stud…

BACKGROUND: Noninvasive biomarkers that predict surgical treatment response would inform personalized treatments and provide insight into potential biologic pathways underlying endometriosis-associated pain and symptom progression. OBJECTI…

Ten Chronic Overlapping Pain Conditions (COPCs) are currently recognized by the National Institutes of Health Pain Consortium (eg, irritable bowel syndrome, chronic migraine headache, and chronic low back pain). These conditions affect mill…

PURPOSE: In patients with urologic chronic pelvic pain syndrome (UCPPS), the presence of widespread pain appears to identify a distinct phenotype, with a different symptom trajectory and potentially different response to treatment than pati…

Exploring the relationship between nociplastic pain and the severity and impact of pelvic pain symptoms could lend insight into the heterogeneous symptom presentation and treatment response that complicates management of chronic pelvic pain…

Dysmenorrhea is characterized by high rates of transition to chronic pain. In a previous study using structural equation modeling, we demonstrated that several symptom domains associated with the emerging concept of nociplastic pain can be …

Pelvic pain in women with endometriosis is attributed to neuroinflammation and afferent nociceptor nerves in ectopic and eutopic endometrium. The hypothesis that uterine nociception is activated by IL-1β, a prominent cytokine in endometrios…

BACKGROUND: Potential impact on sexual function is an often-cited concern for many patients considering hysterectomy. The existing literature indicates that sexual function remains stable to slightly improved for most patients who undergo h…

Chronic pelvic pain (CPP) is multifactorial in etiology and heterogeneous in presentation. Identification of all pain contributors is essential for successful management. Chronic overlapping pain conditions (COPCs) are a specified group of …

BACKGROUND: Our aims were to describe characteristics of sexual function prior to and 6months following benign hysterectomy in patients with three common surgical indications, and to identify preoperative factors that influence the magnitud…

We described trends in pelvic pain characteristics over 2 years of follow-up among adolescents and adults with and without endometriosis participating in the longitudinal observational cohort of the Women's Health Study: From Adolescence to…

BACKGROUND: Chronic pelvic pain is a debilitating problem that afflicts 15% to 20% of women in the United States. Although more than 200,000 hysterectomies are performed annually for the treatment of chronic pelvic pain, previous studies in…

Chronic overlapping pain conditions (COPCs) are a set of painful chronic conditions characterized by high levels of co-occurrence. It has been hypothesized that COPCs co-occur in many cases because of common neurobiological vulnerabilities.…
