🐴 THE HORSE THAT JUST LACKED ENERGY...

This horse was presented with a fairly simple description from the owner which ordinarily would be presumed to be personality. But all consultations give very big clues and my job is; does it match what I find. Sometimes its so glaringly YES!!...........

"He just doesn't seem to have much get up and go."

No obvious lameness.

No dramatic behavioural issues.

Just a horse that felt flat, lacked impulsion and seemed to run out of energy far sooner than expected.

One of the things that caught my eye during assessment was the visible indentation running across the last few ribs.

📸 This horse demonstrates that line particularly well.

From an osteopathic perspective, this region is fascinating because it sits at the crossroads of the respiratory, fascial, musculoskeletal and visceral systems.

The thoracic diaphragm attaches directly to the internal surfaces of the last six or seven ribs.

When the diaphragm becomes restricted, held in an inspiratory pattern, or develops asymmetrical tension, its constant pull can literally draw the ribs inward or prevent their normal outward expansion.

The result can be a visible indentation or "draw line" through the lower rib cage.

The diaphragm is also anchored to the upper lumbar spine through the diaphragmatic crura.

If the lumbar spine becomes restricted, the crura lose their ability to move normally.

This increases tension within the diaphragm.

The diaphragm then increases tension through the ribs.

The ribs alter how they move.

And a self-perpetuating loop of restriction develops.

A closed loop of tension.

But here's where it gets even more interesting...

Because this area isn't influenced only by muscles and fascia.

It's also one of the major meeting points between the diaphragm, lumbar spine, abdominal wall, autonomic nervous system and visceral structures.

And that may explain why some horses don't simply look stiff...

They look tired.

👇

The full case study explores:

• why diaphragm restriction may reduce respiratory efficiency
• how some horses waste energy simply holding tension
• the link between the diaphragm, vagal tone and recovery
• why visceral tension may contribute to these patterns
• what I found in this particular horse

🐴 THE BUMP BETWEEN YOUR HORSE'S EARS MAY BE TELLING YOU MORE THAN YOU THINK

Most horse owners have felt it.

That prominent area at the top of the poll between the ears.

Anatomically, this region is formed by the external occipital protuberance and the nuchal crest.

When I'm assessing a horse, one of the things I pay attention to is whether this area feels symmetrical.

Not because I'm looking for a diagnosis.

And not because I believe the poll is always the source of the problem.

But because, in my experience, the poll often acts as a barometer for the rest of the horse.

What makes this area particularly interesting is that it serves as the anchor point for some of the horse's most important structural and neurological connections.

The nuchal ligament attaches here before running all the way to the withers, helping support the weight of the horse's head and neck.

Directly beneath this region sit the deep suboccipital muscles, including muscles involved in constantly informing the brain where the head is positioned in space.

Many of you will also have seen my past posts on the Myodural Bridge.
I will repeat again soon.

This is where connective tissue links some of these deep muscles directly to the dura mater surrounding the spinal cord.

For me, that's one of the reasons this area becomes so interesting.

Because when I find tension, asymmetry or restriction here, I'm not automatically assuming the problem started at the poll.

I'm asking whether the poll is reflecting something happening elsewhere.

After all, if the horse is compensating through the thoracic sling, ribcage, diaphragm, lumbar spine, pelvis or hindlimbs, those forces have to be managed somewhere.

Quite often, the poll is one of the places where that story becomes visible.

Some horses feel remarkably even.

Others feel as though one side is fuller, higher or positioned more caudal, even more prominent or carries noticeably more tension than the other.

What interests me isn't the shape itself.

It's what I find alongside it.

Can the horse bend equally in both directions?

Does one rein feel heavier than the other?

Is there resistance through the contact?

Does the horse brace through the neck and shoulders?

Can the first ribs move freely? Vascularity & neurologically significant

How is the hyoid apparatus functioning?

What are the TMJs doing?

Can the diaphragm expand and recoil efficiently?

Can the sacrum rock normally during movement?

Because one thing I repeatedly find is that horses often reveal their compensation patterns at the poll long before owners realise they are looking at a whole-body issue.

The horse that struggles with lateral flexion.

The horse that falls through one shoulder.

The horse that leans on one rein.

The horse that struggles with transitions.

The horse that never quite feels comfortable in self-carriage.

The horse that has had the saddle checked, the teeth done, the hocks medicated and yet still doesn't feel completely right.

Those are often the horses that make me look very carefully at this region.

Not because I think the poll is always the cause.

But because it can be an incredibly useful clue.

For horse owners, here's a simple question:

If one side of this area feels fuller, tighter or different from the other, what else do you notice?

🔹 Does your horse bend more easily one way?

🔹 Do they prefer one canter lead?

🔹 Do they lean on one rein?

🔹 Do they struggle with transitions?

🔹 Do they consistently fall through one shoulder?

🔹 Do they feel different to ride on one rein compared with the other?

Sometimes the answer isn't in the poll itself.

Sometimes the poll is simply showing us where to start looking.

👇 Have a feel of your own horse and let me know what you find.

🐴 WHAT IF THE HEAD TILT ISN'T IN THE HEAD?
Lack of FORWARD? UNHAPPY ridden horse?.....

A recent case reminded me why I love looking at the horse as a whole system rather than chasing individual symptoms.

Betty arrived following extensive veterinary investigations.

Her owner had been left with a horse showing:

▪️ Intermittent head tilt when ridden
▪️ An unusual eye roll
▪️ Previous episodes of bolting under saddle
▪️ A history of recurrent colic
▪️ Significant dental pathology requiring ongoing treatment

The dental disease was severe enough to require CT investigation and a long-term management plan. The affected teeth will take time to recover as horses continually erupt their teeth throughout life.

Given the head tilt and eye rolling, I asked for additional structures to be reviewed via her vet team before I would assess her.

The veterinary team investigated and ruled out significant pathology affecting structures such as the temporohyoid region, hyoid apparatus, cranial cervical spine, tympanic bullae and other areas associated with vestibular function.

Once I had that cleared by the vets, Betty came to stay with me for an intensive rehabilitation package.

And this is where things became interesting.

Years earlier, Betty had sustained a major trauma to the front of her chest after being kicked.

There is still a visible defect beneath the manubrium of the sternum today.

So rather than asking:

❓ "Why is the head tilting?"

I started asking:

❓ "How has this horse organised her entire body around that trauma?"

What I found was a remarkable chain of compensation.

The sternum was rotated.

The first ribs were fixed in opposite patterns.

The thoracic inlet was heavily restricted.

Both scapulothoracic junctions were comprised, one in a compensation pattern another in a decompensation pattern.

The hyoid apparatus was pulled left.

The cranial base had lost normal motion.

The diaphragm was significantly more reactive on the left.

The linea alba through the underside of the abdomen felt like a rope.

The sacrum was unable to stabilise properly.

The hind limbs would shake when lifted.

The dorsal sacroiliac region was painful.

And perhaps most interestingly, a clear left-sided compensation pattern ran through much of the body.

Now here's the important part.

None of those findings showed up as "disease" on a CT scan.

Because CT scans are designed to identify pathology.

My job is different.

My job is to assess adaptability.

What moves?

What doesn't move?

What is compensating?

What is DE - compensating?

What has the horse been doing for years to keep functioning despite the original problem?

During Betty's stay I didn't simply perform one treatment and send her home.

Instead we worked in layers.

Some sessions involved equine osteopathy.

Some involved cranial work.

Some involved PEMF.

5 diaphragms

Some involved reassessment.

Some involved very simple somatic movement exercises to help her nervous system organise itself differently.

Throughout the week I constantly adjusted the plan according to Betty's responses.

This is one of the advantages of intensive stay packages.

The horse tells you what it is ready for next.

You are not trying to squeeze everything into a single appointment.

You can listen.

Adapt.

Reassess.

And build change gradually.

Betty's owner also attended my 2 day The Balanced Horse Course. So now she has techniques to help between my sessions.

By the end of her stay:

✅ Pain and sensitivity previously identified throughout the dorsal sacroiliac ligament region had resolved.

✅ Tail tension had resolved, suggesting improved comfort and function throughout the pelvic ring and sacral region.

✅ Hind limb shaking had improved by approximately 90%

✅ The rope-like tension through the linea alba had largely normalised

✅ Cranial motion had improved significantly

✅ The thoracic inlet and rib cage were moving far more normally

✅ Sacral mechanics had improved significantly, with restoration of normal movement into the position of stabilisation

Now she goes home with a programme focused on something many horses actually need far more than stretching:

👉 Stability

Backing up > done correctly which is a process, MOST HORSES ARE BACKING UP INCORRECTLY!

Backing up hills> WHEN READY!

Controlled pole work.

Simple in-hand classical exercises.

Learning to organise her body efficiently again.

Because rehabilitation isn't always about making a horse more flexible.

Sometimes it's about helping them become more stable, more coordinated and more confident within their own body.

This is also how I personally believe body rehabilitation should work.

If a horse has suffered a tendon injury, ligament injury or wound, there are often very specific rehabilitation protocols that need to be followed. Different injuries require different approaches.

But when we are dealing with the horse that still isn't quite right despite months or years of investigation, the horse that has accumulated compensations throughout the body, I believe rehabilitation has to look different.

The horse that has had the SI injected.

The horse that has had the hocks injected.

The horse that has had multiple treatments over the years.

The horse where pathology has largely been ruled out, yet the ride still doesn't feel right.
Or there are pathology but the body aspect doesn't have a thorough work uo

The horse with the head tilt.

The horse lacking impulsion.

The horse that never truly wants to come through the body.

Thr objection to contact horse.

For me, that is where body rehabilitation begins.

Not by chasing individual symptoms, but by understanding how the entire system has adapted around previous injury, pain, trauma or compensation.

Sometimes the problem isn't that the horse needs more flexibility.

Sometimes the horse needs better organisation.

Better stability.

Better breathing.

Better load transfer.

Better communication between the nervous system and the body.

That is what I believe rehabilitation should be aiming to restore.

I've shared one of my whiteboard maps from Betty's assessment which I always do on arrival day of the stay.

It's a good example of how a symptom in one area can lead us to discover a completely different story elsewhere in the horse.

🐴 THE THORACIC INLET DIAPHRAGM

The Junction Between the Head, Neck and Body

Most horse owners have heard of the thoracic sling.

Many have even been told their horse needs to "strengthen the thoracic sling."

But before we jump straight to exercises, there is an important question worth asking:

What sits immediately above it?

The answer is the thoracic inlet diaphragm.

A region that receives surprisingly little attention despite being one of the most important transition zones in the entire horse.

Anatomically, the thoracic inlet sits at the junction between the neck and thorax.

It is formed by the first ribs, manubrium, lower cervical region and the surrounding fascia that envelops blood vessels, nerves, muscles and lymphatic structures as they pass between the head, neck and body.

This is not simply an area where structures happen to pass through.

It is a major communication hub.

The vagosympathetic trunk passes through here.

The recurrent laryngeal nerves travel through this region.

Major blood vessels supplying and draining the head and neck pass through here.

Lymphatic drainage from the head and neck passes through here.

The fascia of the neck blends into the fascia of the thorax here.

And mechanically, this is where forces travelling between the forehand and trunk are constantly being transferred.

Many owners will recognise the horse that:

Feels tight through the base of the neck.

Struggles to truly elevate the withers.

Leans on the forehand.

Finds collection difficult.

Has an inconsistent contact.

Feels restricted through one shoulder.

Lacks quality thoracic sling function despite endless exercises.

Or simply never develops the front-end posture we are aiming for.

The temptation is often to focus entirely on strengthening.

More poles.

More transitions.

More hill work.

More thoracic sling exercises.

And whilst those things absolutely have their place, osteopathy asks a slightly different question.

Can the system actually adapt to the exercise being asked of it?

Because if the fascia around the thoracic inlet has lost adaptability...

If the first ribs are restricted...

If the hyoid apparatus and cervical fascia are transmitting tension downwards...

If the diaphragm cannot move efficiently...

Then the body may not have access to the movement pattern we are trying to strengthen.

One of the reasons the thoracic inlet fascinates me is because it sits directly between two other diaphragms.

Above it lies the hyoid diaphragm.

Below it lies the respiratory diaphragm.

It is literally positioned between breathing, posture, neurology and locomotion.

A bridge between the horse's head and its body.

This is where the osteopathic concept of the five diaphragms becomes so interesting.

Rather than viewing the horse as separate regions, we begin to appreciate a continuous fascial and neurological system extending from the cranial base all the way to the pelvis.

The thoracic inlet is one of the major crossroads along that journey.

And perhaps this is the part worth remembering:

The thoracic sling is not something that exists in isolation.

Nor is it something that can always be trained successfully in isolation.

Because if the hyoid cannot adapt...

If the first ribs cannot adapt...

If the diaphragm cannot adapt...

If the sacrum cannot rock and transmit force efficiently through the body...

Then the thoracic sling is being asked to compensate for a problem that may not actually begin there.

The body functions as a system.

The solutions often need to be approached the same way.

🐴 PART 1: THE CRANIAL BASE & HYOID DIAPHRAGMS

What if the problem isn't where you're looking?

A horse presents:

• Poll sensitive
• Doesn't like contact
• Inconsistent on the reins
• Headshakes
• Struggles with collection
• Holds tension through the underside of the neck
• Feels tight through the shoulders
• Lacks impulsion behind

The temptation is to look at each symptom separately.

The mouth.

The poll.

The neck.

The shoulders.

The hindquarters.

But what if they are all connected?

One of the concepts within osteopathic thinking is that the body functions through a series of integrated "diaphragms" or transitional zones.

Not simply the respiratory diaphragm (the primary muscle of inspiration)...

…but regions where:

fascia

neurology

circulation

pressure systems

posture

movement organisation

and load transfer

all interact.

The first two of these diaphragms are found within the head and throat region:

📍 The Cranial Base Diaphragm

📍 The Hyoid Diaphragm

These regions form a remarkable bridge between the horse's:

skull

tongue

TMJ

poll

cervical fascia

nervous system

and the rest of the body.

The hyoid apparatus itself is a collection of bones suspended between the skull, tongue, mandible and cervical region.

Through structures such as:

the omohyoid

sternohyoid

sternothyrohyoid

styloglossus

hyoglossus

it develops functional relationships with:

the tongue

cranial base

TMJ region

deep cervical fascia

sternum

shoulder region

and the thoracic sling system beneath.

Neurologically, the area interfaces closely with:

the trigeminal nerve (V)

the hypoglossal nerve (XII)

upper cervical structures

the vagus nerve (X)

and the myodural system linking the suboccipital region with the dura mater.

The vagus nerve is particularly interesting because it passes from the cranial base into the neck and thorax, carrying parasympathetic influence to many of the body's organs while travelling through a region rich in fascial, vascular and mechanical relationships.

This is one of the reasons osteopaths often view the cranial base, hyoid apparatus and cervical fascia as part of a wider integrated system rather than isolated anatomical structures.

The cranial base and hyoid are often described as the first two transitional zones within the Five Diaphragms model of osteopathy.

They sit at the junction between the horse's sensory world, postural system and autonomic nervous system.

This is where things become interesting.

Because when the body stops adapting efficiently, the symptoms do not always appear at the source.

A horse may present with:

🔹 Poll restriction

🔹 Difficulty accepting contact

🔹 Asymmetrical rein feel

🔹 Ventral neck tension

🔹 Headshaking

🔹 Altered swallowing

🔹 Changes in posture or balance

🔹 Thoracic sling bracing

🔹 Shortened forelimb stride
..and yet the underlying story may involve far more than the mouth itself.

The body is constantly attempting to preserve:

balance

neurological safety

autonomic regulation

pressure regulation

efficient breathing

and efficient load transfer.

This is one of the reasons I find osteopathy so fascinating.

Rather than asking:

❓ "Which structure is damaged?"

I often find myself asking:

❓ "Which system is no longer adapting efficiently?"

Because horses are incredibly good at compensating.

Until they aren't.

The two study drawings below are part of my own ongoing exploration of these first two diaphragms:

📍 Cranial Base Diaphragm

📍 Hyoid Diaphragm

and some of the fascial, neurological and mechanical relationships that exist within them.

They're certainly not intended as a complete explanation.

But they may start to show why a horse's symptoms do not always originate where they appear.

The horse may be presenting with a mouth problem...

…but carrying it through an entire postural system.

👇 I'd be interested to know:

Had you ever considered that the tongue, hyoid apparatus, cranial base and poll could potentially influence so many seemingly unrelated presentations?

🐴 The 5 Diaphragms of Equine Osteopathy

The word diaphragm does not simply mean “breathing muscle.”

The term originates from the Greek meaning:
“to divide” or “partition.”

Osteopathically, diaphragms can be thought of as key transitional zones or “compartments” within the body…

…areas where pressure, tension, movement, circulation, nerve function and fascial continuity all interact.

And when one loses adaptability, the effects rarely stay local.

One restriction can begin influencing:

- movement
- breathing
- thoracic sling function
- pelvic mechanics
- lumbar stability
- circulation
- nervous system tone
- and compensation patterns throughout the horse.

One of the biggest shifts in osteopathic thinking is moving away from seeing the horse as isolated body parts…

…and instead understanding the horse as a connected system of pressure regulation, load transfer, fascia, neurology and compensation.

This is where the concept of the 5 diaphragms becomes so important.

Not simply “breathing diaphragms”…

…but integrated regions that influence:

- movement
- circulation
- pressure regulation
- load transfer
- proprioception
- compensation patterns
- and even the horse’s ability to relax and organise movement efficiently.

When one area loses adaptability, the body rarely compensates locally.

A restriction through one diaphragm may begin influencing:

- rib mobility
- forelimb loading
- hindlimb engagement
- pelvic organisation
- breathing mechanics
- spinal tension
- autonomic nervous system tone
- and overall movement quality.

This is one of the reasons some horses:

- never seem to “hold” treatment
- continue compensating despite strengthening work
- become chronically tight
- struggle with transitions or canter
- brace through the thorax or pelvis
- appear reactive, tense or unable to soften properly
- or keep developing recurring patterns elsewhere in the body.

Because the body is constantly redistributing pressure, force and tension through the entire system.

The 5 diaphragms are often described osteopathically as including areas such as:

- the pelvic diaphragm
- the respiratory diaphragm
- the thoracic inlet
- the tongue/hyoid complex
- and the cranial/tentorial region

but the important thing is not memorising names.

The important thing is understanding that the horse functions as one integrated system.

Not separate compartments.

This way of thinking completely changes how you begin interpreting:

- movement
- posture
- breathing
- asymmetry
- compensation
- “behaviour”
- recurring rehab failure
- and chronic performance issues.

This is a huge area within osteopathic thinking and something I’ll be expanding on much more in future posts, webinars and courses.

If you’d like me to do separate posts explaining each of the 5 diaphragms individually and how they relate to movement, compensation and the nervous system >

🐴 𝗦𝗜 𝗝𝗼𝗶𝗻𝘁 𝗠𝗲𝗰𝗵𝗮𝗻𝗶𝗰𝘀 𝗨𝗻𝗱𝗲𝗿 𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝗮𝗹 𝗗𝗲𝗺𝗮𝗻𝗱 — 𝗧𝗵𝗲 𝗡𝗲𝘂𝗿𝗮𝗹 𝗖𝗼𝗻𝘀𝗲𝗾𝘂𝗲𝗻𝗰𝗲

Most discussions around SI dysfunction focus purely on structure:

• the joint
• the ligaments
• inflammation
• instability
• muscle weakness

But one of the most important parts of SI dysfunction is often the nervous system.

Because the pelvis is not simply a mechanical structure.

It is a sensory structure.

The sacroiliac region is densely supplied with:

• mechanoreceptors
• nociceptors
• ligamentous sensory endings
• dorsal sacral nerve branches
• fascial neural input

This means the brain is constantly receiving information from the pelvis regarding:

➡️ load
➡️ pressure
➡️ movement
➡️ stability
➡️ limb position

And when pelvic mechanics alter…

the signalling alters too.

𝗧𝗵𝗶𝘀 𝗶𝘀 𝘄𝗵𝘆 𝗦𝗜 𝗱𝘆𝘀𝗳𝘂𝗻𝗰𝘁𝗶𝗼𝗻 𝗶𝘀 𝗻𝗼𝘁 𝗷𝘂𝘀𝘁 “𝗽𝗮𝗶𝗻.”

It becomes a problem of altered motor control.

The horse begins changing movement strategies to protect itself under functional demand.

And this is where owners often start noticing things such as:

• disuniting behind
• bunny hopping in canter
• rushing transitions
• difficulty striking off
• scooting sideways
• reduced impulsion
• crookedness
• toe dragging
• reluctance to collect
• asymmetrical muscle development

Not because the horse is simply weak.

But because the nervous system no longer fully trusts force transfer through the pelvis.

𝗠𝗮𝗻𝘆 𝗰𝗼𝗺𝗺𝗼𝗻 𝗵𝗼𝗿𝘀𝗲 𝗯𝗲𝗵𝗮𝘃𝗶𝗼𝘂𝗿𝘀 𝗮𝗻𝗱 𝗵𝗶𝗻𝗱 𝗵𝗼𝗼𝗳 𝗶𝘀𝘀𝘂𝗲𝘀 𝗮𝗿𝗲 𝗿𝗲𝗹𝗮𝘁𝗲𝗱 𝘁𝗼 𝗮 𝗵𝗼𝗿𝘀𝗲’𝘀 𝘀𝗮𝗰𝗿𝗼𝗶𝗹𝗶𝗮𝗰 𝗷𝗼𝗶𝗻𝘁𝘀.

When you truly have a picture of SI anatomy and force transfer in your mind, you begin making very different decisions in your work with horses.

Because suddenly:
• the canter issue makes more sense
• the hind hoof imbalance makes more sense
• the repeated suspensory strain makes more sense
• the crookedness makes more sense
• the compensation patterns make more sense

And you realise just how many tools you already have available to help the horse become more comfortable and mechanically efficient once the pelvis is factored into the picture.

𝗧𝗵𝗲 𝗡𝗲𝗿𝘃𝗼𝘂𝘀 𝗦𝘆𝘀𝘁𝗲𝗺 𝗔𝗹𝘄𝗮𝘆𝘀 𝗖𝗵𝗼𝗼𝘀𝗲𝘀 𝗣𝗿𝗼𝘁𝗲𝗰𝘁𝗶𝗼𝗻 𝗢𝘃𝗲𝗿 𝗣𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲

During moments of high functional demand:

• canter transitions
• landing forces
• tight turns
• hill work
• collection
• jumping

…the pelvis must rapidly stabilise while simultaneously transferring huge forces into the spine.

This requires precise timing from:

• multifidi
• gluteals
• hamstrings
• thoracolumbar fascia
• pelvic stabilisers

If pelvic mechanics become asymmetrical, afferent input changes.

The brain receives altered information regarding stability.

And motor output adapts accordingly.

𝗧𝗵𝗲 𝗱𝗲𝗲𝗽 𝘀𝘁𝗮𝗯𝗶𝗹𝗶𝘀𝗲𝗿𝘀 𝗼𝗳𝘁𝗲𝗻 “𝗴𝗼 𝗾𝘂𝗶𝗲𝘁.”

The larger superficial muscles begin bracing instead.

This is why many horses with SI dysfunction develop:

• hypertonic lumbar regions
• dominant hamstring recruitment
• reduced gluteal engagement
• asymmetrical loading patterns
• “board-like” backs

The body is trying to create stability somewhere.

𝗔𝗻𝗱 𝘁𝗵𝗶𝘀 𝗶𝘀 𝗸𝗲𝘆:

You cannot fully rehabilitate altered motor control by strengthening alone if the nervous system still perceives instability.

Because the horse will continue defaulting back to protective movement strategies.

𝗧𝗵𝗶𝘀 𝗶𝘀 𝘄𝗵𝘆 𝘀𝗼𝗺𝗲 𝗵𝗼𝗿𝘀𝗲𝘀:

• improve temporarily
• then relapse
• keep developing overload elsewhere
• repeatedly strain suspensories
• continue struggling in canter despite “strength work”

The system never fully reorganised efficient force transfer.

From an osteopathic perspective, this is why assessment must include:

• pelvic mechanics
• sacral motion
• lumbar adaptation
• fascial continuity
• hoof balance
• diaphragmatic influence
• neurological guarding strategies

Because SI dysfunction is rarely isolated.

And the horse is often compensating long before overt pathology appears on imaging.

𝗧𝗵𝗲 𝗦𝗜 𝗷𝗼𝗶𝗻𝘁 𝗶𝘀 𝗻𝗼𝘁 𝗷𝘂𝘀𝘁 𝗮 “𝗷𝗼𝗶𝗻𝘁 𝗽𝗿𝗼𝗯𝗹𝗲𝗺.”

It is a force-transfer and nervous system problem.

🐴 What if the area displaying pain… isn't actually the area causing the problem?

One of the biggest shifts in my work over the years has been moving away from chasing symptoms and instead learning to map the entire compensation pattern of the horse.

Because horses are exceptionally good at adapting.

In fact, many of the painful areas we find are often the body's attempt to protect something else.

The sore lumbar spine.
The tight restricted shoulders.
The reactive SI region.
The short stride.
The "weak hindlimb."
The horse that constantly feels tight again 2 weeks later.

These may not be the beginning of the story at all.

This is where my approach differs significantly from many conventional models.

This is a framework that's been taught in equine osteopathic training for years and yet it's still not the default lens most horses are assessed through.

Understanding and mapping the whole horse across multiple systems simultaneously.
■ Myofascial
■ Parietal / articular
■ Visceral
■ Cranial-sacral
■ Neurological / autonomic
■ Pressure and diaphragmatic systems
■ Load transfer and compensation patterns

Because the horse does not compensate through one system alone.

A hoof issue may alter pelvic loading.
A diaphragm restriction may alter rib mechanics and autonomic tone.
A pelvic torsion may reorganise the thoracic sling.
A cranial base restriction may influence global muscular tone and postural strategy.

‼️Everything is connected.

And this is why I became less interested in simply asking:
"Where does it hurt?"

And far more interested in asking:
"Why is the body protecting this area in the first place?"

‼️This is also why two horses with identical imaging findings can present completely differently.‼️

One adapts.
Another loses the ability to organise load and pressure through the system.

The result?

The body creates compensation after compensation after compensation… until eventually the secondary compensations become louder than the original problem itself.

This is why I find myself in more and more conversations with owners and therapists who feel like something is being missed- horses that aren't failing rehab, but are simply being viewed through too small a lens.

The horse is not a collection of isolated body parts.

It is one integrated neuro-mechanical system constantly adapting to load, pressure, posture, movement, environment and survival.

And when you start viewing the horse that way…

suddenly the compensation patterns begin to make sense.
