What is Visceral Osteopathy: principles and clinical approach

Visceral Osteopathy is a specific area of Osteopathy dedicated to the assessment and intervention of the mobility, motility, and function of internal organs (viscera), as well as their biomechanical, fascial, and neurophysiological interrelationships with the musculoskeletal system and the nervous system.

It is based on the understanding of the human body as an integrated functional unit, in which alterations in visceral function, fascial mechanics, or neurovegetative regulatory mechanisms can be associated with adaptations in other systems, even when symptoms manifest at a distance from the initially involved site.

From this perspective, the internal organs are not rigid or static structures. They exhibit continuous adaptive movements, dependent on breathing, posture, variations in intra-abdominal pressure and regulation by the autonomic nervous system, which is responsible for involuntary functions such as digestion, breathing and heart rate.

When this physiological dynamic is altered, adaptations can arise in the supporting tissues, fascia, ligaments, and mesenteries, structures that support and interconnect organs, with potential repercussions on body mechanics, postural control, and pain perception.

A global and functional view of the body

The human body functions as an integrated and interdependent whole. Since its creation in 1874, Osteopathy has studied the influence of the viscera and alterations in their physiology on the origin of pain and musculoskeletal dysfunctions, recognising their close connection with the locomotor system and the nervous system.

This integrative vision was clearly expressed by Andrew Taylor Still, the founder of Osteopathy, when he stated that “man's system is one and indivisible; any alteration in one organ will have repercussions on the whole organism”.

This principle continues to underpin the contemporary osteopathic approach, in which visceral function, neurological regulation, and musculoskeletal mechanics are understood as inseparable components of the same functional system.

Visceral Osteopathy thus fits into a functional and systemic approach, considering the interdependence between anatomical structures and physiological processes.

The clinical assessment doesn't centre on an isolated organ or a specific symptom, but integrates medical history, lifestyle habits, breathing patterns, movement patterns, muscle tone and the response to stress.

Changes in visceral function can influence segmental muscle tone, meaning the muscle tension associated with certain spinal regions, viscerosomatic reflexes, neurological mechanisms linking organs to musculoskeletal structures, and the regulatory processes of the autonomic nervous system.

For this reason, visceral dynamics are considered clinically relevant in cases of persistent musculoskeletal pain, postural changes or functional symptoms, especially when there is no obvious structural explanation.

Visceral mobility and motility

Movement, in all its forms, voluntary and involuntary, is an essential element for the maintenance of tissue function and health.

In Visceral Osteopathy there are two fundamental concepts, although they are interdependent.

• Visceral mobility: It refers to the passive movement of organs in relation to adjacent structures, namely the diaphragm, abdominal wall and spine, during breathing, postural changes and overall body movement. It depends on the integrity of the visceral fascia, suspension ligaments and the ability of tissues to slide against each other.
• Visceral motility: This corresponds to intrinsic rhythmic micromovements in each organ, associated with its physiological activity, local blood perfusion, and modulation by the autonomic nervous system. These micromovements are subtle, but relevant for tissue adaptation and the body's sensory integration.

Osteopathic assessment seeks to identify restrictions, asymmetries, or alterations in these parameters and to understand how they may be contributing to the person's overall clinical picture.

Relationship between viscera, fascia and musculoskeletal system

The viscera are suspended and interconnected by a continuous fascial system, a connective tissue that connects and surrounds all the structures of the body.

The visceral fascia exhibits viscoelastic properties and a high density of mechanoreceptors, sensory receptors sensitive to pressure and movement, playing an active role in force transmission and body perception.

From a functional point of view, internal organs, suspended by fascia and ligaments, require relative mobility to adapt to the body's global movement and respiration.

Changes in this dynamic can influence the distribution of tensions in the global fascial system and the mechanics of different musculoskeletal regions.

In parallel, the high density of sensory receptors present in visceral and fascial tissues allows mechanical stimuli to be integrated at a central level, with potential repercussions on muscle tone, postural control, and the perception of discomfort.

In certain clinical contexts, changes in tension or mobility in a visceral region can be associated with joint restrictions, changes in breathing patterns, changes in muscle tone and compensatory postural adaptations.

Changes in visceral function can also be associated with changes in fascial tension, tissue mobility and neurovascular dynamics, with possible repercussions on other structures in the body.

Musculoskeletal pain of visceral origin

Visceral Osteopathy considers musculoskeletal pain of visceral origin a clinically relevant phenomenon for understanding symptoms that manifest at a distance from the primary site of dysfunction.

One of the main mechanisms involved is referred pain, which results from the convergence of sensory information from the viscera and musculoskeletal tissues at the level of the dorsal horn of the spinal cord, a central area of nerve integration.

Classic models of autonomic neurophysiology describe how visceral and somatic afferents converge on the same spinal neurons, making it difficult for the central nervous system to discriminate the origin of the nociceptive stimulus.

This mechanism can lead to the interpretation of visceral signals as pain localised in musculoskeletal structures such as the dorsal, lumbar or cervical spine, as well as in the shoulder girdle, constituting the neurophysiological basis of referred pain, widely described in the literature (Wilfrid Jänig; Cervero & Laird, 1999).

Under normal physiological conditions, the viscera have low nociceptive sensitivity.

However, processes such as inflammation, distension, ischaemia or local biochemical alterations significantly increase the excitability of visceral afferents, especially type C fibres (Gebhart, 2000).

When this stimulation becomes persistent, central sensitisation phenomena can develop, characterised by an increase in neuronal responsiveness and a reduction in the nociceptive threshold (Woolf, 2011).

In this context, usually non-painful somatic stimuli can be perceived as painful, leading to segmental reflex responses such as increased muscle tone, myofascial rigidity, and altered cutaneous sensitivity in specific metameric territories.

These manifestations do not necessarily reflect structural musculoskeletal pathology, but rather a neurophysiological modulation process sustained by continuous visceral afference, as described in the models of segmental pain and referred pain (Nikolai Bogduk, 2009).

Integrating these autonomic models with contemporary data on visceral mechanotransduction allows us to understand how visceral mechanical or sensory alterations can contribute to persistent musculoskeletal pain states.

The sustained increase in visceral afferent flow to the spinal cord can reinforce viscerosomatic convergence mechanisms, facilitate central sensitisation processes, and perpetuate patterns of segmental pain, muscle stiffness, and associated autonomic changes, as described in the chronic pain literature (Cervero, 2009; Woolf, 2011).

How Visceral Osteopathy works

Visceral Osteopathy intervention is based on an integrative and individualised clinical assessment. It uses soft manual techniques, essentially passive, including myofascial approaches, applied to the abdomen, chest or other relevant regions, according to the clinical assessment.

In general, the intervention seeks to:

• to favour the mobility of organs and their supporting structures;
• reduce tension restrictions in the visceral connective tissue;
• facilitate sliding between fascial planes;
• modulating the sensory information sent to the nervous system;
• support the regulation of the autonomic nervous system;
• contribute to more efficient respiratory and postural mechanics.

Work on respiratory mechanics is of particular relevance, given the functional relationship between the viscera, diaphragm, rib cage, and spine. Respiration constitutes a central element in autonomic regulation and the global mechanical adaptation of the body.

The human body is in constant motion, both voluntary and involuntary. This involuntary movement manifests from cellular processes to the rhythmic activity of the heart, diaphragm, and digestive system. Visceral Osteopathy seeks to respect and support this intrinsic dynamic, promoting functional coordination and neurophysiological adaptation.

Simple clinical examples

In a clinical context, visceral dynamics can be considered relevant in various situations. For example, a person with persistent lower back pain, with no significant structural changes on imaging scans, may present with restrictions in colon mobility or altered respiratory mechanics, associated with fascial tension patterns and increased lumbar muscle tone.

In another example, an individual with recurring neck discomfort and a feeling of tension in the shoulder girdle may show alterations in thoracic mobility and the functional relationship between thoracic viscera, the diaphragm, and the cervical spine, influencing muscle tone regulation and postural control.

These examples don't imply a direct cause-effect relationship, but they show how visceral and fascial adaptations can be integrated into a broader clinical picture, contributing to the persistence of symptoms.

What the osteopath assesses in practice

The assessment in Visceral Osteopathy is always global and individualised. In addition to specific observation and palpation, the osteopath integrates different dimensions of the person, namely:

• Detailed clinical history and evolution of symptoms: It includes analysing the onset of complaints, their evolution over time, aggravating or alleviating factors, relevant medical history and previous interventions. This information makes it possible to contextualise the symptoms and understand the body's adaptation patterns.
• Lifestyle habits, diet, stress levels and sleep quality: These are everyday factors that directly influence the regulation of the autonomic nervous system, digestive processes, the inflammatory response and the ability of tissues to recover, and can interfere with the expression of symptoms.
• Breathing patterns and diaphragm mobility: Breathing assessment makes it possible to observe the coordination between the ribcage, diaphragm and abdomen. Changes in these patterns can influence visceral mobility, posture, autonomic regulation and the distribution of tension in the fascial system.
• Posture and movement patterns: The way the person positions themselves and moves on a daily basis is analysed, identifying compensations, asymmetries and protective strategies that may be associated with the persistence of pain or dysfunction.
• Segmental muscle tone and joint mobility: The presence of increased or decreased muscle tone in specific spinal segments is assessed, meaning the degree of activation of certain muscle groups, as well as joint mobility. These changes may reflect neuromuscular adaptations and viscerosomatic reflex mechanisms, associated with the integration between the nervous system, internal organs, and the musculoskeletal system.
• Quality of fascial tissue and visceral mobility: Elasticity, sliding capacity, and fascial tissue response are observed, as is the relative mobility of organs. Changes in these parameters can reflect mechanical and sensory adaptations relevant to the overall clinical picture.

The assessment is not limited to identifying local restrictions, but seeks to understand how the body organises itself, compensates and adapts to different internal and external stimuli.

Clinical situations where Visceral Osteopathy may be considered

In certain clinical contexts, Visceral Osteopathy can be integrated as part of a global and individualised approach. Some examples of situations in which visceral dynamics may be clinically relevant include:

• persistent or recurrent musculoskeletal pain;
• low back pain and chest pain with no clear structural cause;
• neck pain and headaches associated with postural or respiratory changes;
• abdominal discomfort or a feeling of abdominal discomfort;
• slow digestion, postprandial heaviness or functional constipation;
• heartburn and gastroesophageal reflux, in the context of altered diaphragmatic mechanics;
• functional changes of the hepatobiliary system;
• menstrual pain associated with pelvic or abdominal tension patterns;
• symptoms in which stress and the regulation of the autonomic nervous system seem to play an important role.

Clinical background

These frameworks do not imply that the origin of symptoms is exclusively visceral, nor that there is a direct cause-and-effect relationship. Each situation must be assessed individually. Their clinical relevance is analysed on a case-by-case basis, integrating osteopathic assessment with the clinical history, lifestyle habits and the overall context of the person, especially when there are persistent, recurrent or structurally difficult-to-explain symptoms, and appropriate medical referral whenever necessary.

In this context, Visceral Osteopathy is part of a responsible clinical approach and does not replace medical assessment whenever there are warning signs or suspicions of organic pathology. Situations such as fever, unexplained weight loss, severe or progressive pain, neurological changes, digestive haemorrhages or persistent vomiting require priority in the appropriate medical screening.

A person-centred approach

At the heart of the intervention is always the person, their story, and the unique way their body adapts. Visceral Osteopathy is based on a thorough assessment of medical history, lifestyle habits, and the biopsychosocial context, recognising that each body responds uniquely to the demands of daily life, stress, and life experiences.

Osteopathic intervention seeks to support the body's intrinsic self-regulation mechanisms, creating conditions for more efficient functional adaptation, respecting its limits and its intrinsic capacity for functional reorganisation. An integrated osteopathic approach considers, in an articulated way, the musculoskeletal system, the visceral system, and the nervous system, respecting the uniqueness of each person.

At Integrativa, Visceral Osteopathy consultations are integrated into a global clinical approach. This intervention is complemented by Clinical Psychoneuroimmunology, allowing us to frame factors such as sleep, physical exercise, a healthy diet, stress regulation, and relaxation strategies, with the aim of supporting the body's self-regulation, preventing symptom recurrence, and promoting the maintenance of results over time.
