Neurophysiology and Somatic Dysfunction


Click to view


Most people think of a muscle injury as a structural problem — damaged fibres, inflamed tissue, restricted joint movement. But what if the most significant and lasting changes after an injury happen not in the muscle itself, but in the nervous system that controls it? This is the central insight of Constanze Rouyer’s elegant and intellectually rich thesis, which draws on neuroscience, proprioception research, and osteopathic theory to argue that canine somatic dysfunction is, at its core, a neurological phenomenon.


Rouyer begins with a precise overview of the neuromuscular system — the interplay of alpha and gamma motor neurons, muscle spindles, Golgi tendon organs, and sensory neurons — and explains how this intricate signalling network maintains posture, coordinates movement, and protects the body from overload. When injury occurs, this system does not simply reset. The muscle spindle, still receiving elevated gamma discharge, begins reporting a contracted state as normal resting length. The central nervous system loses its ability to distinguish dysfunction from homeostasis, effectively locking the compensation in place.


Drawing on the concept of neuroplasticity — “neurons that fire together, wire together” — Rouyer then explains how these maladaptive patterns can become structurally embedded in the nervous system over time, generating chronic pain sensitisation, altered motor control, and postural imbalances that persist long after the original tissue injury has healed. The thesis culminates in a compelling argument for the Functional Technique as a form of neurological rehabilitation — an indirect osteopathic approach that, by following the ease of motion rather than engaging the barrier, gently resets the muscle spindle’s resting reference point and allows the nervous system to relearn what homeostasis feels like. Enriched by Rouyer’s personal observations treating rescue and shelter dogs, this thesis is a thoughtful, evidence-grounded case for a more neurologically informed approach to canine osteopathic care.

Osteopathy Challenges Modern Equine Dentistry

Statistics about equine dental disease are striking. A 1994 survey of 500 equine skulls found evidence of dental disease in 80% of subjects. By 2012, a UK study identified dental irregularities in 95.4% of horses aged fifteen and over — yet only a quarter of owners were aware their horse had a problem requiring attention. Despite decades of routine dentistry, these numbers have barely shifted. Christina Hall, writing for the London College of Animal Osteopathy, asks a provocative question: could the way we approach equine dentistry be part of the problem?


Hall, who practises as both an equine osteopath and a qualified equine dentist in the United States, brings a rare dual perspective to this thesis. Her central argument is that modern equine dentistry operates almost exclusively within an allopathic framework — addressing the visible signs of dental abnormality, from hooks and ramps to ulcerations and malocclusions, without asking why those abnormalities exist in the first place. She contends that the answer almost always lies in immobility somewhere in the body, and that osteopathic assessment is the tool best placed to find it.


The thesis draws on A.T. Still’s four principles of osteopathy to reframe every aspect of dental care. If a horse presents with recurring tongue ulceration, for instance, the standard response is to file the offending tooth surface. But Hall argues the cause is likely restriction at the temporomandibular joint — and that restriction, in turn, may originate in a hoof imbalance, a visceral restriction, or a fascial tension pattern running from the hind limb to the skull. The concept of the ‘six legs’ — the three paired extremities of mandible, forelimbs, and hindlimbs that govern mobility patterns across the horse’s entire body — is introduced as a clinical lens for understanding how restriction in one region cascades throughout the whole.


Hall reserves particular concern for routine dental practices such as prolonged speculum use and head positioning on extended dental stands, arguing that these techniques place the upper cervical spine into hyperextension and impose excessive strain on the apical ligament and the temporomandibular joint disc. With nine of twelve equine myofascial kinetic lines originating or terminating at the skull, the downstream consequences of dental procedures performed in biomechanically unsound positions may be far greater than is currently appreciated. This is a thesis that will challenge the assumptions of every equine professional who reads it.

Fascia and Osteopathy in Dogs

29 Jun 2026 Canine

Fascia, often overlooked, is a foundational structure in the body: a continuous, intricate network of connective tissue that dynamically connects muscles, bones, organs, vessels, and nerves. It functions as a critical communication system influencing movement, posture, immunity, and pain. For canine osteopaths, a deep understanding of fascia is essential.


In this compelling thesis, Christina Schaumann explores the biological and clinical significance of fascia within canine osteopathic practice. Drawing on both pioneering research from the Fascia Research Congress and the foundational tenets of Dr. Andrew Still’s osteopathy, the paper establishes fascia as the structural and physiological element linking all major health models: biomechanical, neurological, respiratory-circulatory, metabolic, and behavioural.


Schaumann clearly explains fascia’s composition—a collagenous fibre network with four distinct layers—and details how its cellular elements, including fibroblasts and myofibroblasts, respond to injury, mechanical stress, and therapeutic intervention. The work addresses how fascial dysfunction leads to common canine issues such as chronic pain, restricted movement, trigger points, and adhesions. It then illustrates how core osteopathic methods, including Myofascial Release, Functional Technique, and Osteopathic Articular Balancing (OAB), directly resolve these problems.


Crucially, the thesis incorporates comparative anatomy research, confirming significant structural parallels between canine and human fascia. This allows for direct application of human fascia science insights to animal patients. Schaumann powerfully asserts that the osteopathic treatment of the fascial system activates the body’s inherent self-healing mechanisms, a central pillar of osteopathic medicine itself.


This thesis offers a clinically grounded and fascinating perspective for dog owners, veterinary professionals, and students of animal therapy, clarifying why a whole-body osteopathic approach is so profoundly effective.

Fascia and Pelvic Diaphragm

26 Jun 2026 Canine

The pelvic floor is rarely the first place a dog owner or even a veterinarian looks when a dog develops incontinence, postural problems, or tail dysfunction. Yet the pelvic diaphragm — a complex musculo-fascial structure forming the caudal boundary of the pelvic cavity — plays a surprisingly central role in a wide range of canine health issues. In this richly detailed thesis, veterinary surgeon and osteopath Dr Chiara Adorini brings this underexplored region into sharp clinical focus.


The thesis opens with a thorough comparative anatomy of the pelvic diaphragm across dogs, humans, and horses, revealing both the structural differences and the shared myofascial logic that makes osteopathic principles transferable across species. In dogs, the levator ani and coccygeus muscles — ensheathed in layers of deep pelvic fascia — form a continuous supportive network for the bladder, rectum, and reproductive organs, and contribute to continence, locomotion, and tail movement.


Drawing on the osteopathic “five-diaphragm model,” Adorini explains how tension or dysfunction in the pelvic diaphragm can cascade upward through the body, influencing breathing, spinal function, and organ health. She then catalogues the clinical dysfunctions that can arise — from perineal hernia and fecal incontinence to lumbosacral pain and post-surgical complications — and the contributing factors: aging, spay/neuter surgery, trauma, and postural imbalances.


Crucially, the thesis outlines a practical toolkit of osteopathic manual techniques — including myofascial release, Osteopathic Articular Balancing, recoil technique, and acupressure integration — and how each can be adapted and applied to restore pelvic function in canine patients. For practitioners working in rehabilitation or integrative veterinary care, this thesis is a clinically valuable and anatomically precise guide.

Osteopathy and Poor Hoof Morphology

22 Jun 2026 Equine

The hoof is often treated as a farriery problem — a question of angles, balance, and correct trimming. But what if poor hoof morphology is not just a foot problem, but a whole-body problem? In this thought-provoking and expertly reasoned thesis, Cheryl Hammerson makes the case that osteopathy and farriery are not separate disciplines, but deeply interconnected partners in equine health.


Anchored in the second principle of osteopathy — that structure and function are interrelated — Hammerson walks the reader through a compelling argument: that the body and the hoof shape each other in a continuous, dynamic feedback loop. When a horse develops pathology in the stifle or hip, compensatory loading patterns over time distort hoof morphology. Conversely, poor hoof structure — long toes, low heels, broken hoof-pastern axes — imposes abnormal forces on the entire musculoskeletal system, generating postural dysfunction, back pain, and eventually lameness.


The paper is enriched by real-world case examples, including a detailed account of a show pony whose refusal to jump, aggressive pain response, and postural collapse were traced to severely imbalanced hind hooves. Once the farrier addressed the foot balance and osteopathic treatment restored mobility to the horse’s soft tissues and spine, the pony returned to competition. Three comparative hoof assessment examples — measured with the HoofmApp tool — further illustrate how hoof asymmetry correlates with diagnosed pathology in the opposite limb.


Hammerson also draws on emerging research in human osteopathy and posture science to strengthen the case for equine application. The conclusion is clear: to care effectively for the horse’s hooves, you must care for the whole horse — and that is exactly what osteopathy is designed to do.

Osteopathy’s Systemic Effects in Horses

15 Jun 2026 Equine

Equine osteopathic manual therapy is widely used to improve biomechanics and support rehabilitation, yet its systemic physiological effects have rarely been rigorously measured. In this thesis, Carla Pujadó analyses the findings of a landmark controlled study involving thirty Thoroughbred horses to examine how a single OMT session — using Pascal’s high-velocity, low-amplitude technique — produces measurable changes across three of the body’s most important regulatory systems: the autonomic nervous system, the immune system, and thehypothalamus-pituitary-adrenal axis.


The results are striking. Blood serum cortisol rose significantly in the experimental group immediately after treatment, then declined toward baseline within an hour — a transient HPA axis activation consistent withpatterns observed in human OMT research. White blood cell counts showed a parallel fluctuation, indicating an acute immune response rather than a sustained inflammatory shift. Body temperature increased significantly in treated horses, pointing to autonomic involvement in thermoregulation, while heart rate trends suggested a shift toward parasympathetic dominance, even when changes fell short of statistical significance.


Pujadó situates these findings within ten clinical cases — horses presenting with neurological deficits, pelvic asymmetry, suspensory desmitis, and chronic thoracolumbar pain — demonstrating how the physiological responses documented in the study map onto real-world presentations. The thesis also confronts an uncomfortable gap: despite OMT’s growing clinical use, only one published study examines its systemic physiological effects in horses. Pujadó identifies the methodological, funding, and standardisation barriers that have slowed this research, and makes a compelling case for why closing that gap matters — not just for science, but for the horses practitioners treat every day.

Osteopathy for Behavioral Hurdles

8 Jun 2026 Equine

Every horse carries its physical history in its body. The old falls, the awkward landings, the years spent compensating for an undiagnosed restriction — these experiences accumulate as somatic dysfunctions that quietly shape how a horse handles, moves, and responds under saddle. In this practical and perceptive thesis, Bethany Rice — drawing on more than a decade as a full-time professional trainer before qualifying as an animal osteopath — explores the physical roots of some of the most common and frustrating problems in horses.


The thesis is structured around three categories: handling issues, behavioural problems, and performance limitations. For each, Rice identifies the likely anatomical origins, walks through the clinical reasoning, and outlines an osteopathic treatment approach. Head shyness is traced to atlanto-occipital dysfunction and compression of the poll nerves. Resistance during farriery maps to joint pain, brachial plexus nerve impingement, or sacral and lumbar lesions, depending on which limb is involved. Girthiness reliably points to rib head and thoracic vertebral dysfunction at segments T8-T12. Bucking at canter, a behaviour often managed through training alone, is reframed here as a probable expression of sacral or lumbar neuralgia that worsens as the horse transitions to a different gait.


Performance limitations receive equally detailed treatment. Bit resistance is examined through the lens of the atlanto-occipital joint, C2 dysfunction, and the hyoid apparatus. Preferred bend patterns are categorised as Type 1 or Type 2 lesions — each with a distinct presentation, origin, and treatment pathway. The concept of diagonal synchrony is used to explain why a restriction in one limb produces a corresponding reduction in the contralateral diagonal.


Throughout, Rice makes a clear and compelling argument: that what trainers often interpret as stubbornness or training failure is often the body communicating a need for restoration rather than correction.

Osteopathy in Early Canine Development: Why the First Weeks Matter Most for Your Puppy’s Lifelong Wellbeing

5 Jun 2026 Canine

A puppy tumbling across the floor looks the picture of uncomplicated health. They bounce, they stumble, they right themselves and tumble again. And yet, beneath that joyful chaos, something quite remarkable — and quite vulnerable — is happening. The musculoskeletal system of a young dog is not simply a miniature version of the adult. It is an actively changing, highly sensitive structure whose early experiences can leave lasting impressions on how that animal moves, compensates, and ages.

For practitioners trained in classical structural osteopathy, early canine development represents both an opportunity and a responsibility. Understanding what is happening in the young dog’s body, and how osteopathic assessment fits into that picture, is knowledge that has real clinical relevance.

The Developing Musculoskeletal System

Canine skeletal development begins in utero, but the growth story continues long after birth. Puppies are born with significant cartilaginous tissue in place of mature bone, and ossification proceeds progressively through the early months and years of life. Growth plates — the physes — remain open until skeletal maturity, which varies considerably by breed. In small breeds, this process may be largely complete by 10 to 12 months. In large breeds this process takes until around 18 months, and in giant breeds up to 24 months — considerably longer than their smaller counterparts

This extended developmental window matters clinically. The growth plates are biomechanically weaker than mature bone, and the surrounding soft tissues. Ligaments, tendons, and joint capsules are still calibrating their tension and elasticity in response to the forces the puppy experiences during normal activity. We know from Wolff’s Law that bone changes its density and architecture in response to the mechanical loads placed upon it. Applied to the growing dog, this means the patterns of movement, posture, and loading established early in life are genuinely formative.

Compressive or torsional forces applied repeatedly to an immature joint can alter its trajectory of development. Conversely, varied, appropriate movement on suitable surfaces encourages healthy proprioceptive development and joint congruency.

What Birth Itself Can Do

It is worth pausing on the birth process specifically, because it is rarely discussed in the context of canine development despite its potential significance.

Whelping places considerable compressive and shearing forces on the neonatal body — particularly through the cranium, cervical spine, and thorax. In difficult or protracted births, these forces are amplified. The cranial bones of a newborn puppy are not yet fully fused; they are designed to be somewhat mobile, allowing passage through the birth canal. This same mobility, however, means the cranial structures can sustain strain patterns that persist beyond the birth process itself.

In clinical practice, some experienced animal osteopaths observe that neonates from difficult whelping such as prolonged labour, assisted extraction, and caesarean delivery can present with asymmetric head carriage, difficulty latching, restricted cervical mobility, or altered suckling patterns. These presentations may seem subtle in the first days of life, but they can have downstream effects on the pup’s ability to feed efficiently, which in turn affects growth, weight gain, and immune status in those critical early weeks.

Craniosacral approaches, used with great care and extremely light contact appropriate to the neonate, can be employed to assess and address such strain patterns. The work done with foals and calves in this area — including documented cases of neonates presenting with neurological-type symptoms following difficult births that resolved following craniosacral intervention — offers useful analogues for the canine patient.

The Early Weeks: Reflex Patterns and Postural Organisation

In the first two to three weeks of life, a puppy’s movement is governed largely by reflexes rather than conscious motor control. The righting reflex, the rooting reflex, and the extensor thrust response all feature prominently. The nervous system is still in rapid development, and the muscular system is building its foundational tone.

During this period, the puppy’s primary physical activities are suckling, sleeping, and crawling through the whelping box. The surface they crawl on, the positioning during sleep, and even the way they are handled can influence early musculoskeletal patterning.

Neonates that spend extended time on very slippery surfaces, for example, may develop excessive abduction of the hind limbs. A presentation sometimes described as “swimmers puppy” is when the hindlimbs splay laterally and the pup cannot achieve the normal crawling and standing postures required for healthy hip and stifle joint development. Addressed early with positional support and appropriate surface management, many of these pups recover well. Left unattended, the consequences for joint development can be significant.

Growth Phases and the Osteopathic Assessment

As the puppy moves through the rapid growth phase, broadly from weaning at four to eight weeks through to adolescence, the body is in a state of constant flux. Bones lengthen. Muscles adapt to meet new lever lengths. The nervous system refines its proprioceptive mapping of a body that is literally a different shape week to week.

In terms of canine conditioning, the principles that apply to the adult dog apply in modified form to the developing pup: progressive, appropriate challenge of the musculoskeletal system promotes adaptation and resilience, while overload, whether through excessive exercise, inappropriate surfaces, or inadequate recovery, risks injury to vulnerable growth plates and soft tissues.

An osteopathic assessment during this developmental window is not about looking for gross pathology. It is about evaluating the quality of movement, the symmetry of soft tissue tone, the mobility of spinal segments and peripheral joints, and the overall pattern of how the puppy is organising itself in gravity. Minor asymmetries or areas of restriction found at this stage, before compensatory patterns have had months or years to consolidate, are considerably more amenable to treatment than their adult equivalents.

Practitioners should assess through observation of spontaneous movement before hands-on work. Gait, posture, spinal alignment, and the way the pup loads and unloads its limbs all carry information. Palpation follows — soft tissue texture and tension, articular mobility through gentle passive assessment, and the overall quality of tissue in regions that may be under mechanical stress.

Breed-Specific Developmental Considerations

Not all puppies carry the same developmental risk profile, and this is an area where practitioners benefit from genuine breed literacy.

The relationship between selective breeding and musculoskeletal health in dogs is complex and, in some respects, troubling. Breeds selected for extreme conformational features, such as exaggerated angulation of the hindlimb, foreshortened skulls, and disproportionate body length relative to limb length, carry inherent biomechanical vulnerabilities that are present from birth and worsen as the animal grows. For a deeper look at how these breed-related structural characteristics affect health across the life of the dog, the LCAO article Breed Related Health Difficulties in Dogs provides an overview.

For the osteopath, these breed considerations shape the assessment priorities. A Labrador puppy from working lines has a very different growth trajectory and associated risk profile to a French Bulldog or a Basset Hound. Large and giant breeds, where the bone-to-cartilage ratio takes longest to shift, require particular care around exercise loading during rapid growth phases. Chondrodystrophic breeds — those with genetically short limbs and elongated spines — carry elevated intervertebral disc disease risk that begins accumulating in structural terms from early in life.

Assessing these pups with an understanding of breed-specific anatomy, rather than applying a generic template, is essential to clinically meaningful osteopathic work.

What Osteopathy Can Realistically Contribute

There is an important distinction to draw here between what osteopathic care can offer and what it cannot. Osteopathy does not correct genetic structural abnormalities. It cannot alter the shape of a skull or change the angle of a coxofemoral joint that has developed with inherent laxity. What it can do is work with the secondary and compensatory consequences of those structural realities. In the developing puppy, it can help ensure that the body is given the best possible mechanical environment in which to organise itself as it grows.

Specifically, osteopathic treatment in the young dog may address areas of soft tissue tension that are restricting normal joint mobility, restore appropriate spinal segmental movement in regions that have become restricted following birth strain or an early fall, improve proprioceptive input to the nervous system through gentle articular work, and provide the owner or breeder with practical, evidence-informed guidance on exercise, surfaces, and handling.

The referral relationship with the veterinary team is always central. Osteopathy in the developing puppy sits within a collaborative framework. It is not a standalone intervention but one component of holistic developmental care that may also include veterinary imaging, nutritional guidance, and physiotherapy input where indicated.

Practical Guidance for Breeders and Owners

For breeders in particular, osteopathic assessment of a litter during the early weeks, or at least of any pups from a difficult whelping, represents a genuinely proactive approach to canine welfare. The window of greatest developmental plasticity is also the window of greatest opportunity for low-intervention, high-impact care.

A few principles worth carrying into practice: ensure whelping surfaces provide adequate traction to support normal postural development, as non-slip bedding material in the first weeks has measurable effects on limb position and hip development. Handle neonates frequently, but with care for the spinal axis and with attention to symmetrical rather than asymmetrical positioning. Monitor feeding patterns closely in the first 24 to 48 hours. A pup that is reluctant to latch, or that consistently favours one side, may warrant early assessment. Introduce varied, appropriate physical challenge as the pup grows — different textures underfoot, gentle inclines, social play — without exposing the immature skeleton to repetitive high-impact loading.

And when in doubt, have the animal assessed. The earlier a compensatory pattern is identified, the less work there is to do.

A Clinical Area Worth Taking Seriously

Early canine development is not a niche concern for breeders alone. Any practitioner working with adult dogs presenting with musculoskeletal complaints, asymmetric gait patterns, or chronic soft tissue restrictions is, in some measure, working with the accumulated legacy of that animal’s developmental history.

Understanding what happens in the first weeks and months of a dog’s life, and what osteopathic care can contribute during that time, deepens clinical practice in ways that benefit animals at every life stage.

Osteopathy and Sport Horse Performance

1 Jun 2026 Equine

What separates a well-trained horse from a truly high-performing one? According to Asia Peruzzetto’s thesis, the answer lies not in genetics or training intensity alone, but in the structural harmony that underpins every stride, jump, and transition. Her comprehensive exploration focuses on the role of osteopathy in equine athletic performance. By integrating biomechanical research, breed-specific anatomy, and clinical evidence, the work makes a strong case for incorporating manual therapy as a fundamental component of sport horse management.


Peruzzetto begins by mapping the diverse physical demands placed on horses across disciplines — from the torsional hock stress of reining to the thoracolumbar strain of dressage collection, the tendon load of flat racing, and the metabolic demands of endurance. The study analyzes how breed morphology influences both athletic capability and injury risk. Specifically, it notes that Thoroughbreds are prone to suspensory inflammation during intense training; European Warmbloods require diligent management of their sacroiliac region; and Arabians competing over long distances need structured, gradual conditioning to safeguard their flexor tendons.


This thesis provides a compelling argument for the multidimensional effects of osteopathy on athletic horses. The evidence presented goes beyond improved joint mobility, drawing on studies that demonstrate osteopathic treatment induces changes in autonomic tone, cortisol regulation, and immune markers. This highlights how manual therapy contributes to the horse’s overall physiological resilience, not just its musculoskeletal health. Key areas where osteopathy offers measurable value include: enhancing post-competition recovery, improving proprioception, and facilitating the early detection of compensatory movement patterns.


The thesis closes with a call for larger, inter-breed comparative studies to consolidate osteopathy’s place within evidence-based equine sports medicine — a field the author clearly intends to shape professionally.

Osteopathy for Riding Problems

26 May 2026 Equine

When a horse resists the aids, tosses its head, or suddenly loses rhythm through a transition, the instinct is often to look at the training. But what if the problem isn’t in the schooling — what if it’s in the body? This is the central question explored in Anne Éfféré’s thoughtful and well-structured thesis, which makes a compelling case that many of the most common riding problems are not behavioural in origin, but physical — and that equine osteopathy offers a meaningful path to resolving them.


Drawing on current research and established osteopathic principles, Éfféré systematically maps the links between specific physical dysfunctions — including musculoskeletal imbalances, joint restrictions in the sacroiliac and cervical spine, and compensatory movement patterns — and the riding problems they cause. A horse labelled stubborn for refusing to bend may simply have cervical spine restrictions. A horse that bucks during transitions
may be communicating discomfort in the sacroiliac region. Without understanding the physical root cause, training corrections not only fail to resolve the problem — they can make it worse.


The thesis also introduces key osteopathic techniques, including structural mobilisation, soft tissue manipulation, Osteopathic Articular Balancing (OAB), and craniosacral therapy, exploring how each addresses specific dysfunctions. Importantly, Éfféré emphasises that osteopathy works best as part of a collaborative approach — one that brings together the practitioner, trainer, and rider to observe, respond, and adapt. A valuable read for anyone working with horses who don’t quite feel right under saddle.
