SI dysfunction is rarely isolated.

The pelvis doesn't compensate alone.

The sacrum influences the lumbar spine.❗️horse with back pain ❓️

The ilium influences how forces are transferred through the rest of the body. That horse short striding!

The body constantly redistributes load in an attempt to maintain balance.

Some compensations are helpful.

Some become overloaded.

Some eventually fail.

And when they do, symptoms often appear far away from the original driver.

The really interesting question then becomes:

👉 What is influencing the pelvis?

Because every breath changes pressure through the thorax, abdomen and pelvis.

The diaphragm influences the lumbar spine.

The lumbar spine influences the sacrum.

The sacrum influences how load is transferred through the hind limbs.

The shoulder doesn't function in isolation.

The jaw doesn't function in isolation.

The spine doesn't function in isolation.

The body is constantly adapting to maintain balance.

This is why two horses can present with similar symptoms yet have completely different underlying compensation patterns.

And why the area that appears to be the problem is not always where the story begins.

Perhaps the more useful question isn't:

❓ "Which joint is causing the issue?"

Perhaps it's:

❓ "How is the horse organising load through the entire system?"

That is exactly what I'll be exploring in Webinar 2.

Not just the pelvis.

But the systems that influence the pelvis.

𝗜𝘁’𝘀 𝗮 𝗵𝗼𝗰𝗸 𝗶𝘀𝘀𝘂𝗲…

“It’s the suspensory...”

“It’s the stifle...”

Sometimes it is.

But often...

👉 that's where the problem shows up, not where it starts.

𝗪𝗵𝗲𝗻 𝘁𝗵𝗲 𝗽𝗲𝗹𝘃𝗶𝘀 𝘀𝘁𝗼𝗽𝘀 𝗺𝗮𝗻𝗮𝗴𝗶𝗻𝗴 𝗹𝗼𝗮𝗱 𝘄𝗲𝗹𝗹...

The sacrum cannot alternate properly between:

• stability (nutation)

• mobility (counternutation)

That means:

👉 load is no longer transferred cleanly

👉 the system loses its ability to deal with asymmetry

So the body adapts.

Instead of loading one hind limb at a time...

👉 the horse starts to bring both limbs through together.

𝗪𝗵𝗮𝘁 𝘆𝗼𝘂 𝗺𝗮𝘆 𝘀𝗲𝗲

• bunny hopping in canter

• disuniting / cross canter

• loss of suspension

• difficulty maintaining rhythm

Because the system is avoiding:

👉 unilateral load

𝗪𝗵𝗲𝗿𝗲 𝘁𝗵𝗲 𝗹𝗼𝗮𝗱 𝗴𝗼𝗲𝘀 𝗻𝗲𝘅𝘁

When load is not managed through the pelvis...

👉 it has to go somewhere.

So we often see:

• hock overload

• proximal suspensory strain

• uneven push-off behind

• quarters in

And above this...

👉 the lumbar spine starts to compensate.

The lumbar facet joints are designed to:

• allow controlled movement

• share load across the spine

• adapt between flexion and extension

But when the sacrum is not functioning correctly...

👉 the lumbar spine loses its normal relationship with the pelvis.

So instead of balanced movement:

• certain segments become overloaded

• others become restricted

• the system stiffens rather than adapts

This can show up as:

• reduced ability to engage

• difficulty with transitions

• resistance to canter work

• "tightness" that keeps returning

• Reluctance to lift limbs

𝗦𝗼 𝘆𝗼𝘂 𝗲𝗻𝗱 𝘂𝗽 𝘄𝗶𝘁𝗵...

👉 a limb problem

👉 a spinal problem

👉 a performance problem
..but all potentially linked to the same underlying issue:

👉 a system that is no longer managing load effectively.

These are not separate issues.

They are different expressions of the same system under strain.

But here's the question that interests me most...

𝗪𝗵𝘆?

Why does the pelvis stop managing load well in the first place?

Is it simply weakness?

Is it simply conditioning?

Or are there other systems influencing the pelvis that we rarely discuss?

Because the pelvis doesn't operate in isolation.

The shoulder doesn't operate in isolation.

The jaw doesn't operate in isolation.

The spine doesn't operate in isolation.

The body is constantly adapting and compensating to maintain balance.

If one part changes position, other regions often respond.

Some compensations are helpful.

Some become overloaded.

Some eventually fail.

And when they do, symptoms begin to appear.

The really interesting part?

The pelvis is only one piece of the story.

Every breath changes pressure through the thorax, abdomen and pelvis.

The diaphragm connects directly into the lumbar spine.

The ribs influence how the thorax moves.

The lumbar spine influences the sacrum.

And the sacrum influences how load is transferred through the hindlimbs.

In other words...

Perhaps the pelvis isn't always the beginning of the story.

Perhaps it is responding to influences elsewhere in the system.

That is exactly what I'll be exploring in my SI joint Webinar 2.

Not just the SI joint and its dysfunction , But the systems that influence the SI joint and what they create compensation.

Limited places to ensure Q n A

12/06/2026

Yesterday was a full day in Sheffield.
Lots of different patterns in their bodies, but 1 thing in common > the resulting Pandiculations that happened in the majority I looked at.

A horse doing a pandiculation, often called a "full-body stretch" is a natural reflex where they tense, stretch and then slowly release muscle activity. It is thought to help reset muscle tone, improve movement awareness, increase circulation and prepare the body for efficient movement.

Unlike static stretching, a pandiculation involves three distinct phases:

• A gentle muscular contraction
• A lengthening phase as the body stretches
• A slow release back to a resting state

From an equine osteopathic perspective, these movements are particularly interesting because they involve the entire body working as a connected system rather than as isolated muscles.

When Andrew Taylor Still founded osteopathy in 1874, one of the central ideas was that structure and function are inseparable. Although the modern term somatic dysfunction was developed later, the principles that evolved into this concept were already being described by osteopathic physicians in the late 1800s.

Today, somatic dysfunction refers to impaired or altered function within the body's framework, including joints, muscles, fascia and their related neurological, vascular and lymphatic components.

Modern osteopathy recognises that dysfunction may develop through several pathways:

• Mechanical restrictions within joints, fascia and connective tissues
• Altered neurological input affecting muscle tone and movement patterns
• Viscerosomatic influences, where irritation or dysfunction within an internal organ contributes to muscular tension and altered movement elsewhere in the body
• Somatovisceral influences, where persistent musculoskeletal dysfunction may influence autonomic nervous system activity and organ function

In the horse, this helps explain why seemingly unrelated findings often occur together.

A horse presenting with restriction through the thoracic diaphragm may also demonstrate altered rib mechanics, thoracolumbar tension, reduced spinal mobility, changes in posture, shortened stride length or a reduced willingness to move forward.

Likewise, long-standing dysfunction affecting the digestive tract, respiratory system or urogenital structures may contribute to persistent changes in muscle tone and movement patterns through viscerosomatic reflex pathways.

From an osteopathic perspective, these compensatory patterns are not viewed as isolated problems. They are considered part of a wider adaptive response occurring throughout the entire body.

The stretch itself is not the treatment.

Rather, it can be viewed as the body expressing a moment of neurological and mechanical reorganisation.

One reason I find these moments fascinating is that they remind us that the horse does not experience the body in separate parts. The nervous system, fascia, joints, muscles, diaphragm, circulation and internal organs are constantly communicating with one another.

Good movement is rarely about a single structure.

It is usually about the quality of communication throughout the entire system.

This is why osteopathy has always looked beyond the site of symptoms. More than 150 years after Andrew Taylor Still first described the importance of the relationship between structure and function, the body continues to demonstrate the same lesson:

Everything is connected.

🐴 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?
