Endometriosis is a benign gynecological condition where the uterine endometrium is located outside the uterus. The condition affects up to 10% of women of fertile age and up to 70% of women with endometriosis have symptoms with severe pain during menstruation (dysmenorrhea), pain during intercourse (dyspareunia), and/or chronic pelvic pain. Current treatments are dictated by the primary symptom: pain and are limited to surgery and hormonal treatments with often short-lived effects. Advances in the understanding of the condition have expanded to focus on less invasive and non-pharmacological treatments. Systematic reviews and meta-analyses of observational studies have focused on the protective role of physical activity and exercise on the risk of developing endometriosis. The results from these studies have been inconclusive. However, the efficacy of physical activity and exercise on pain among women with endometriosis has not been tested in high-quality randomized controlled trials (RCT).
Due to the complexity of the disease, international clinical guidelines recommend that the treatment of endometriosis-associated pain should come from a multimodal and multidisciplinary perspective. Numerous non-pharmacological treatments have been proposed to alleviate endometriosis-associated pain, such as physical activity. Physical activity was introduced as a factor in the treatment of endometriosis-associated pain over three decades ago, with the possible beneficial effect that physical activity stimulates anti-inflammatory properties that will impede the development of endometriosis and lower the pain. A recent systematic review and meta-analysis found one randomized controlled study that showed no effect of physical activity on endometriosis-associated pain. They concluded that the methodological quality of this study was low, and the need for future randomized controlled studies was warranted. We, therefore, aimed to study the effect of pain education and group-based physical activity versus pain education alone on women with endometriosis-associated pain.

All participants will attend a four-hour pain education session including gynecologist, psychologist, sexologist, and physiotherapist at Akershus University Hospital. The education will be held twice, with half of the participants at the time. The training group will then attend a 60 minutes weekly group training session led by a physiotherapist with specialist training in women's health over a period of four months. In addition, participants will perform a progressive home exercise program performed daily over the same period. The focus will be general strength training using own body weight and cardiovascular fitness (walking, low-impact aerobic exercise), stretching, and relaxation

Endometriosis associated pain
Electronically patient-reported pelvic and genital pain will include a pain body map and pain intensity scale (NRS). We will ask for average pain, worst pain, and conditional pain over the course of one month.
Time frame: Measured at baseline and after 4 months and 12 months
Level of physical activity
Electronically patient-reported physical activity level will be measured using the International physical activity questionnaire-short form (IPAQ-SF). We will analyse MET values and categories of activity in addition to walking
Time frame: Measured at baseline and after 4 months and 12 months
Pelvic floor muscle maximal contraction and resting tension
Pelvic floor muscle maximal contraction and muscular endurance will be measured with manometer using a vaginal balloon catheter Camtech Sandvika Norge AS (cmH2O) will be assessed. This method has demonstrated good validity and reliability, by our research group. Resting tension and the ability to contract using surface electromyography (EMG) will be used with a vaginal probe (Quintet). We will also perform vaginal palpation to assess pain/tenderness and tone. (All women will be instructed on how to correctly perform a pelvic floor muscle contraction prior to assessment).
Time frame: Measured at baseline and after 4 months
Sexual function and sexual pain
Electronically patient-reported assessment using the Female Sexual Function Index (FSFI). We will also use questions adapted from Sahlgrenska University Hospital related to sexual pain. Higher scores indicates more problems. range 0-36
Time frame: Measured at baseline and after 4 months and 12 months
Depression and anxiety
Electronically patient-reported assessment using Hopkins Symptom Check List (SCL-5). Hopkins Symptom Checklist (SCL-5) was used to evaluate psychological distress, a higher score (up to 20) indicating greater psychological distress. range 0-20
Time frame: Measured at baseline and after 4 months and 12 months
Pain with urination
Electronically patient-reported assessment of pain prior to, during or after urination (developed by urologists at Akershus University Hospital). Categories of answers. Alternatives will be yes/no. questions will also cover if the symptom increases during menstruation with alternatives yes, no, sometimes, always
Time frame: Measured at baseline and after 4 months and 12 months
Bowel function
Electronically patient-reported assessment of bowel function including pain and constipation using the Knowles-Eccersley-Scott-Symptom (KESS). Higher scores indicating more problems. range 0-39
Time frame: Measured at baseline and after 4 months and 12 months
Health economy and related quality of life
Electronically patient-reported assessment using health-related quality of life questionnaire (EQ5D). Higher scores indicating better health. Questions also include questions on health care utilisation with categories over the last 4 weeks. Three questions on quality of life will also be included measured on a scale (0-10).
Time frame: Measured at baseline and after 4 months and 12 months
Fear of movement
Tampa scale measuring fair of movement. Fair avoidance with Tampa Scale for Kinesiophobia (TSK-13), which score ranges from 0 - 52, 4 subcategories, "subclinical" (score 13-22), "mild" (score 23-32) "moderate" (score 33-42) and "severe" (score 43-52).
Time frame: Measured at baseline and after 4 months and 12 months
Pain with defecation
Electronically patient-reported assessment of pain prior to, during or after defecation (developed by urologists at Akershus University Hospital). Categories of answers. Alternatives will be yes/no. questions will also cover if the symptom increases during menstruation with alternatives yes, no, sometimes, always
Time frame: Measured at baseline and after 4 months and 12 months
General pain
General pain will be assessed with a body map in addition to self-developed questions. Alternatives will be yes/no. questions will also cover if the symptom increases during menstruation with alternatives yes, no, sometimes, always
Time frame: Measured at baseline and after 4 months and 12 months
