The main objective of this study is to know if the application of both therapies, neuroscience pain education plus therapeutic exercise will modify pain, catastrophizing and quality of life in endometriosis.
Endometriosis is a chronic and inflammatory gynecological condition characterized by the growth of endometrial- like tissue within and outside the pelvic cavity (uterus).
With current means and diagnostic systems, a prevalence of 10% is estimated, although the evidence warns that with the improvement of early diagnosis, these figures will be much higher in the future. One of the main problems with endometriosis is the late diagnosis, which takes an average of seven years. Added to this is the fact that until a definitive diagnosis, patients live in the adolescent stage with symptoms (around 50% with severe pelvic pain) that cause disability and changes in activity and participation in daily life.
At the social level, endometriosis patients are known to have limitations in academic and work activities, as well as in social participation. All of this causes high economic costs.
Chronic pelvic pain can cause the phenomenon of central nervous system sensitization in which pain processing is altered. Pain catastrophizing significantly affects pain disability and vice versa in endometriosis.
Conventional medical care is based on hormonal, pharmacological, and / or surgical treatment and is carried out on an individualized basis depending on the severity of the treatment and the patient's needs.
The multidisciplinary approach to endometriosis has gained relevance in recent decades and has been considered by leaders in the clinical and research sectors. Within the multidisciplinary team, physiotherapy has gained relevance in recent decades.
The multimodal approach of physiotherapy is the one that the Clinical Practice Guidelines and national and international documents demand with greater relevance. Therapeutic exercise based on the work of the abdominal stabilizing musculature and motor control appears to be effective in the treatment of nonspecific low back pain and in endometriosis-related pain. But there is no 'gold standard' in terms of dosage, considering the individualization of treatments.
In the biopsychosocial care paradigm, and specifically in the approach to pathologies with primary chronic pain, patients tend to be motivated and accompanied toward self-determination to achieve adherence to treatment through health education strategies, adequate information, and personalized and goal-oriented multimodal treatment.
However, today, nonadherence is positioned as a global problem, which is growing as the burden of chronicity of pathologies increases, influencing health outcomes and long-term healthcare costs.
Due to symptomatology especially related to chronic pain in endometriosis and in the context of the biopsychosocial paradigm demanded by the scientific community, the investigators consider pertinent the study of catastrophization and its relationship with quality of life and, therefore, disability, and an intervention that addresses in a multimodal way the physiotherapy treatment for endometriosis.
It is recognized that physiotherapeutic interventions based on therapeutic exercise programs, both individual and group, are most effective when tailored to the needs of everyone. Part of this customization should focus on the barriers that each patient recognizes to treatment adherence.
For this reason, the investigators found that studies that support further research to increase the basic understanding of the factors that act as a barrier to adherence in physical therapy treatments could facilitate the development of strategies to overcome nonadherence. And if the investigators follow international recommendations, these systems should address adherence and compliance to treatment from a multidimensional perspective.
Therefore, the investigators believe that measuring compliance and adherence to treatment in this way in patients with endometriosis would allow to know whether adherence to the proposed exercise programs in the target population and their effectiveness are really related or not to the adherence rates to treatment as suggested in recent publications.
In view of the above, this project aims to examine the relationship between the efficacy of physical therapy treatment in patients diagnosed with endometriosis measured in clinical and quality of life terms with short-term compliance and short- and medium-term adherence rates.

Exclusion Criteria:
Application of a multimodal physical therapy program based on pain education and therapeutic exercise. Sixteen sessions will be carried out. The sessions will be carried out with a frequency of two days a week. Subjects will receive 6 PAIN NEUROSCIENCE EDUCATION (PNE), and 8 weeks (2 times/ week) of therapeutic exercise.
Procedure: PAIN NEUROSCIENCE EDUCATION AND THERAPEUTIC EXERCISE PROGRAM
Usual Care. Application of standard medical treatment. In Spain, the treatment provided is mainly pharmacological, adjusted to the symptomatic profile of theses patients.
Procedure: USUAL CARE
PAIN NEUROSCIENCE EDUCATION 1\. Introduction to the knowledge of pain in the XXI century. Pain as an alarm system. Types of pain. Differences between acute and chronic pain. 3. Chronic pain. Concepts of kinesiophobia, catastrophism and fear avoidance, self-determination and neuroplasticity. 4\. Main pain management tools based on scientific evidence. 5. . Transtheoretical model of change. Adherence to treatment, importance as a determinant in health. 6\. Messages for home. Strategies of active coping in the maintenance stage. THERAPEUTIC EXERCISE PROGRAM 10-min warm-up. Joint mobility exercises with dual task or gamification. 30-min main part. Sequence of balance work between strength and body flexibility dosed according to the specific needs of each participant. 10-min cool down including breathing exercises and motor imagery. Home exercise program: walking (150 minutes in total, 3 days alternating with the face-to-face sessions).
The treatment provided is mainly pharmacological, adjusted to the symptomatic profile of theses patients. Conventional medical care is based on hormonal, pharmacological and/or surgical treatment and is carried out on an individualized basis depending on the severity of the disease and the patient's needs, especially in matters of desire to become pregnant. Surgical treatment is carried out when pharmacological therapy (hormonal or anti-inflammatory) is ineffective or involves adverse events.
Change from Self-report Pain magnitude
Magnitude of chronic pain: Chronic pain grading scale. Likert-type scale with 8 items that are evaluated between 0 and 10 for items 2, 3, 4, 6, 7 and 8. Item 1 collects the number of days with pain in the last six months. Item 5 rates the impediment to the performance of usual tasks in the last three months, and can be evaluated between none and 90. The higher the score, the greater the chronic pain involvement. If the score is zero, the patient will be rated as having no pain. Chronic pain will be of low interference with grade I (low intensity) or grade II (high intensity) or of high interference with grade III (moderately limiting) or grade IV (severely limiting). Persistence will be graded as non-persistent or persistent pain.
Time frame: At the start of the study (at baseline, 0 week), 1 month and 2 months after the start of the intervention (4 and 8 weeks), 1 month from the last session (12th week), 3 months from the last session (20th week) and 6 months from the last session (32th week
Treatment Compliance
Self-report of the person responsible for managing attendance at the group sessions in the experimental group. Participants who attend 80% or more of the sessions will be considered compliant.
Time frame: From enrollment to the end of treatment at 8 weeks
Treatment adherence (Maintenance of the therapeutic exercise program at home )
Adherence to treatment (experimental group), measured by visual analogue scale (VAS) included in the patient diary, in terms of: Maintenance of treatment at home: number of days that the proposed exercise is performed (100% being 2 times a week). Each patient will complete the VAS scale monthly. Participants with a score equal to or greater than 8 points out of 10 on the VAS scale will be considered to have high adherence.
Time frame: From the end of the intervention at 8 weeks (starting at week 9) to the end of treatment at 32 weeks.
Changes from Self-report pain catastrophizing
Catastrophizing thoughts in the face of pain: Pain Catastrophizing Scale (PCS). Pain catastrophizing is a construct that is related to a negative and exaggerated orientation towards painful stimuli. The scale, validated in Spanish, is a list of 13 statements that describe different thoughts and feelings that may be related to pain in the dimensions of rumination, magnification and hopelessness. The person indicates the degree to which he/she has such thoughts or feelings by rating them between 0 (not at all) and 4 (all the time). The theoretical range of the instrument is between 13 and 62, with higher values indicating a higher index of catastrophizing.
Time frame: At the start of the study (at baseline, 0 week), 1 month and 2 months after the start of the intervention (4 and 8 weeks), 1 month from the last session (12th week), 3 months from the last session (20th week) and 6 months from the last session (32th week
Change from Self-report specific quality of life
Specific quality of life: Endometriosis Health Profile (EHP-30+23) questionnaire Spanish version. The questionnaire is composed of two parts. Part 1 with 30 itmens and part 2 divided into five subscales: pain, control and helplessness, emotional well-being, social support and self-image. For part 1 and each subscale a total score is created as a percentage of the maximum possible score. 0 is considered the best possible health status and 100 the worst.
Time frame: At the start of the study (at baseline, 0 week), 1 month and 2 months after the start of the intervention (4 and 8 weeks), 1 month from the last session (12th week), 3 months from the last session (20th week) and 6 months from the last session (32th week
Changes in self-reported general quality of life
Overall Quality of Life: EUROQOL-5 Dimensions- 3 Levels (EQ-5D-3L). It is a standardized instrument that measures health outcomes and is applicable to a wide range of diseases and treatments. It provides a simple descriptive profile and a single index of health status. The EQ-5D-3L covers 5 dimensions of health: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is assessed in 3 categories (no problems; moderate problems; extreme problems). The assessment consists of measuring each of the 5 domains in one of the 3 categories. In this work we use, as in our reference study, the validated Spanish version of the EQ-5D-3L in its current version for the adult population. EQ-5D © 2025 EuroQol Research Foundation.
Time frame: At the start of the study (at baseline, 0 week), 1 month and 2 months after the start of the intervention (4 and 8 weeks), 1 month from the last session (12th week), 3 months from the last session (20th week) and 6 months from the last session (32th week
Exercise-related adverse events
Possible occurrence of pain, frequency of flares and fatigue, measured qualitatively in narrative text through patient diary.
