Endometriosis and manual therapy: an adjunctive role

Endometriosis is an estrogen-driven chronic inflammatory condition in which tissue resembling the endometrium grows outside the uterus, producing pain, adhesion and frequently infertility. Its primary management belongs to gynaecology: hormonal suppression, laparoscopic excision when indicated, pharmacological pain management, and multidisciplinary coordination that often involves pelvic floor physiotherapy, psychology, nutrition and pain medicine. Manual therapy sits at the edge of this picture, with a specific contribution — honestly stated — rather than a primary treatment role.

What manual therapy does not do

Before describing the contribution, the limits must be explicit. Manual therapy does not treat endometriosis. It does not reduce the inflammatory burden, it does not regress endometriotic lesions, it does not replace hormonal or surgical management. A practitioner who positions visceral manipulation as a treatment for endometriosis is overreaching and misleading patients who are already exhausted by years of inadequate care. This is a condition where honest scope is particularly important.

Where manual work contributes

Within the broader care picture, manual therapy has a specific adjunctive role in four dimensions:

Post-surgical rehabilitation. Endometriosis excision surgery — often extensive, involving bowel, bladder or deep pelvic structures — produces predictable post-surgical fascial patterns. Pelvic peritoneum adhesion, diaphragmatic loading from Trendelenburg positioning, abdominal wall fascial restrictions at port sites. Addressing these systematically in the weeks and months after surgery can reduce the residual pain and functional restriction that many patients report despite successful excision.

Chronic pelvic pain with fascial contributors. Even when medical management is in place and endometriotic activity is suppressed, a significant fraction of patients continue to report pelvic pain. Fascial patterns — utero-sacral ligament restriction, pelvic peritoneum loading, obturator internus and levator ani fascial tension, pudendal nerve entrapment patterns — persist after the primary inflammatory driver is reduced and sustain a pain picture that gynaecology alone cannot fully address.

Autonomic dysregulation. Chronic inflammatory pelvic pain produces sustained sympathetic activation and parasympathetic suppression, with consequences that extend beyond the pelvis: gastrointestinal dysfunction, sleep disruption, anxiety patterns. Vagal work at the cervical level and polyvagal-framed autonomic regulation contribute to the broader quality-of-life picture.

Diaphragmatic and visceral envelope work. Many patients with advanced endometriosis show restricted diaphragmatic mobility from chronic pain-driven breathing patterns and from surgical history. Restoring diaphragmatic function has effects that cascade through the abdominal and pelvic visceral envelope.

The clinical sequence

For a patient with confirmed endometriosis and medical management in place, a Barral-trained practitioner typically works through a structured sequence:

Sessions 1–2. Listening-based assessment of the primary territory. Often the utero-sacral region, sometimes the bladder-uterus interface, sometimes a specific surgical site, sometimes the diaphragm as the dominant pattern.

Sessions 3–6. Direct pelvic visceral work on the identified primary, with secondary work on pelvic floor fascia, peritoneum, adjacent nerves (pudendal, obturator) and diaphragmatic release. Coordination with a pelvic floor physiotherapist is often important in this phase.

Sessions 7–10. Consolidation, autonomic regulation, integration with the patient\'s self-management and exercise plan. By this stage, the manual work has either produced meaningful change or it has not — and the honest assessment matters more than the optimistic continuation.

Coordination with the gynaecological team

Responsible manual therapy in endometriosis requires close coordination. The gynaecologist remains the primary clinician. When a pelvic floor physiotherapist is involved, her work is complementary and often shares patients with manual therapy — the two approaches address different aspects of the pelvic picture. The pain specialist, where involved, manages the pharmacological and interventional pain dimensions. The psychologist, where involved, addresses the emotional and cognitive dimensions that chronic pain invariably brings.

The manual therapist\'s contribution is specific, time-limited and honest about its scope. Patients deserve practitioners who know where their work fits and where it stops.

When manual therapy is not appropriate

Manual work should be paused or avoided in specific situations: active inflammatory flare with acute pain requiring medical re-evaluation, recent surgery before clearance from the surgical team, suspected bowel or bladder involvement that has not been medically characterised, and any presentation where continuing manual care would delay a needed medical intervention. This judgement is part of responsible practice and is taught explicitly in the Barral advanced modules.

Research context

Research on visceral manipulation specifically for endometriosis-related pain is limited to case series and small controlled studies with positive signals. Research on manual therapy for chronic pelvic pain more broadly is more developed. Research on post-surgical pelvic rehabilitation, including manual components, supports an adjunctive role in the specific post-excision window. Practitioners should present manual work as adjunctive and be transparent about the evidence base and its limits.

Training path

Practitioners developing endometriosis-focused practice should have VM1, VM2, VM3 and LT1 as a minimum, with NM3 (pelvic nerves), AVMHC (neuroendocrine) and PVMT1 (autonomic) as the extended track. Clinical experience with pelvic populations and coordination with gynaecology and pelvic floor physiotherapy teams matters as much as the technical training. At our Madrid centre these modules form a coherent multi-year pathway for practitioners committing to pelvic pain work.
