He won't go forward
A kick when you put your leg on.
A buck through the transition.
Running faster instead of striking off.
Picking up the wrong lead.

Or simply saying 𝗡𝗢 to going forward.
It's very easy for these things to become labelled as behavioural.

And yes, behaviour can absolutely become learned. Previous experiences, anticipation, fear and training all matter. What's happening in the mind affects the body, and what's happening in the body affects the mind.

But there's another question I think we need to ask.

𝗪𝗵𝗮𝘁 𝗶𝗳 𝘁𝗵𝗲 𝗵𝗼𝗿𝘀𝗲 𝗶𝘀 𝘀𝗮𝘆𝗶𝗻𝗴 𝗻𝗼 𝗯𝗲𝗰𝗮𝘂𝘀𝗲 𝘁𝗵𝗲 𝗺𝗼𝘃𝗲𝗺𝗲𝗻𝘁 𝘄𝗲'𝗿𝗲 𝗮𝘀𝗸𝗶𝗻𝗴 𝗳𝗼𝗿 𝗶𝘀 𝗴𝗲𝗻𝘂𝗶𝗻𝗲𝗹𝘆 𝗱𝗶𝗳𝗳𝗶𝗰𝘂𝗹𝘁 𝗼𝗿 𝘂𝗻𝗰𝗼𝗺𝗳𝗼𝗿𝘁𝗮𝗯𝗹𝗲?

When I assess horses with this type of presentation, I don't just look at the behaviour and I don't just look at the area where the rider feels the problem.

I want to know what the 𝘀𝗮𝗰𝗿𝘂𝗺 is doing.
What are the 𝗶𝗹𝗶𝗮 doing?
How has the 𝗹𝘂𝗺𝗯𝗮𝗿 𝘀𝗽𝗶𝗻𝗲 compensated?

Is there a persistent side-bending pattern through the lumbar and thoracolumbar region?

What is happening through the 𝗿𝗶𝗯𝗰𝗮𝗴𝗲 𝗮𝗻𝗱 𝗱𝗶𝗮𝗽𝗵𝗿𝗮𝗴𝗺?

Because the pelvis and lumbar spine don't function as separate pieces.

Alter the mechanics of the sacrum and pelvis and the lumbar region has to organise around that.

That compensation can continue through the trunk and influence how much movement the horse has comfortably available in each direction.

So one canter may fit relatively easily within the horse's existing compensation.

Then we ask for the opposite canter.

Now we're asking the pelvis, lumbar spine, trunk and limbs to organise differently - potentially away from the pattern the horse has been using to keep itself functioning.

And that's when you may see:

𝗧𝗵𝗲 𝗸𝗶𝗰𝗸. 𝗧𝗵𝗲 𝗯𝘂𝗰𝗸. 𝗧𝗵𝗲 𝘁𝗮𝗶𝗹 𝘀𝘄𝗶𝘀𝗵. 𝗧𝗵𝗲 𝘄𝗿𝗼𝗻𝗴 𝗹𝗲𝗮𝗱. 𝗧𝗵𝗲 𝗺𝗼𝘁𝗼𝗿𝗯𝗶𝗸𝗶𝗻𝗴. 𝗧𝗵𝗲 "𝗻𝗼 𝗳𝗼𝗿𝘄𝗮𝗿𝗱".

These aren't diagnoses.
𝗧𝗵𝗲𝘆'𝗿𝗲 𝗰𝗹𝘂𝗲𝘀.
And they're clues I think we should listen to.

Because if the response is simply to retrain the behaviour - even using gentle, sympathetic horsemanship, 𝗵𝗮𝘃𝗲 𝘄𝗲 𝗲𝘀𝘁𝗮𝗯𝗹𝗶𝘀𝗵𝗲𝗱 𝘄𝗵𝘆 𝘁𝗵𝗲 𝗵𝗼𝗿𝘀𝗲 𝘄𝗮𝘀 𝘀𝗮𝘆𝗶𝗻𝗴 𝗻𝗼 𝗶𝗻 𝘁𝗵𝗲 𝗳𝗶𝗿𝘀𝘁 𝗽𝗹𝗮𝗰𝗲?

And here's an uncomfortable question worth considering:

𝗜𝗳 𝗮𝗻 𝘂𝗻𝗱𝗲𝗿𝗹𝘆𝗶𝗻𝗴 𝗽𝗵𝘆𝘀𝗶𝗰𝗮𝗹 𝗽𝗿𝗼𝗯𝗹𝗲𝗺 𝗵𝗮𝘀𝗻'𝘁 𝗯𝗲𝗲𝗻 𝗶𝗱𝗲𝗻𝘁𝗶𝗳𝗶𝗲𝗱, 𝗶𝘀 𝘁𝗵𝗲𝗿𝗲 𝗮 𝗽𝗼𝘀𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝘆 𝘁𝗵𝗮𝘁 𝗿𝗲𝗽𝗲𝗮𝘁𝗲𝗱 𝘁𝗿𝗮𝗶𝗻𝗶𝗻𝗴 𝗰𝗼𝘂𝗹𝗱 𝘁𝗲𝗮𝗰𝗵 𝘁𝗵𝗲 𝗵𝗿𝘀𝗲 𝘁𝗵𝗮𝘁 𝗼𝗯𝗷𝗲𝗰𝘁𝗶𝗻𝗴 𝗮𝗰𝗵𝗶𝗲𝘃𝗲𝘀 𝗻𝗼𝘁𝗵𝗶𝗻𝗴?

Could apparent compliance sometimes be mistaken for resolution?

Could we, in some cases, be moving towards 𝗹𝗲𝗮𝗿𝗻𝗲𝗱 𝗵𝗲𝗹𝗽𝗹𝗲𝘀𝘀𝗻𝗲𝘀𝘀 rather than fixing the reason the horse objected in the first place?

I'm not saying every kick, palyful buck has a physical cause.

But I am saying that 𝗯𝗲𝗵𝗮𝘃𝗶𝗼𝘂𝗿 𝗶𝘀 𝗶𝗻𝗳𝗼𝗿𝗺𝗮𝘁𝗶𝗼𝗻.

And before deciding that a horse 𝘄𝗼𝗻'𝘁, I want to be as certain as possible that the horse 𝗰𝗮𝗻.

That may mean looking much further than the obvious area - considering the 𝘃𝗶𝘀𝗰𝗲𝗿𝗮𝗹, 𝗽𝗮𝗿𝗶𝗲𝘁𝗮𝗹, 𝗺𝘆𝗼𝗳𝗮𝘀𝗰𝗶𝗮𝗹 𝗮𝗻𝗱 𝗰𝗿𝗮𝗻𝗶𝗼𝘀𝗮𝗰𝗿𝗮𝗹 𝗿𝗲𝗹𝗮𝘁𝗶𝗼𝗻𝘀𝗵𝗶𝗽𝘀 throughout the horse, alongside appropriate veterinary investigation where pain or pathology is suspected.

Because sometimes you need to follow the compensation before the behaviour starts to make sense.

But does YOUR horse actually need more movement in that direction?
Because this is the bit social media often misses.
Before I stretch a horse, I want to know what direction that horse is already biased towards — and what direction it is struggling to access.
If the scapulothoracic junction is already biased up and back, repeatedly taking the limb forward may not be the answer.
That horse may actually need help finding the opposite direction — down and forward through the scapulothoracic junction — before asking it to organise the limb differently.
And another horse may present completely differently.
So the question isn't:
“What does this stretch stretch?”
The better question is:
“Have I tested whether this horse actually needs it?”
There are very few universally “good” exercises.
The right exercise is the one that matches the horse in front of you.
TEST. THEN INFLUENCE.
Want to learn how to assess the horse in front of you — rather than simply applying generic stretches and exercises?

𝗔 𝗧𝗢𝗢 𝗖𝗢𝗠𝗠𝗢𝗡 𝗦𝗖𝗘𝗡𝗔𝗥𝗜𝗢.

Could the shape of your horse’s hindquarters be telling you more than you realise?

I see this pattern all the time.

A raised (kyphotic) lumbar area followed by a dip through the back towards the lumbosacral region, often with L6 held more in extension.

A pelvis that appears to drop away behind it. Less development through parts of the gluteals and quadriceps, while the hamstrings become much more developed and dominant.

It’s common enough that we can start to think it’s simply how some horses are built.

𝗕𝘂𝘁 𝗰𝗼𝗺𝗺𝗼𝗻 𝗱𝗼𝗲𝘀𝗻’𝘁 𝗻𝗲𝗰𝗲𝘀𝘀𝗮𝗿𝗶𝗹𝘆 𝗺𝗲𝗮𝗻 𝗻𝗼𝗿𝗺𝗮𝗹.

And this is where I think we need to stop looking at hocks, suspensories, stifles, backs and SI regions as completely separate problems.

Because the hindlimb doesn’t function separately from the pelvis and lumbar spine.

The muscles creating movement at the top of the limb influence what happens further down it, while the nerves supplying the hindlimb arise from the lumbosacral region ......(that dip)!

Then add the diaphragm, abdominal pressure, fascia, organs, hoof balance, training and the rest of the horse’s compensatory pattern...

Suddenly a 𝗵𝗼𝗰𝗸 𝗽𝗿𝗼𝗯𝗹𝗲𝗺 isn’t necessarily only a hock story.

And a 𝘀𝘂𝘀𝗽𝗲𝗻𝘀𝗼𝗿𝘆 𝗽𝗿𝗼𝗯𝗹𝗲𝗺 isn’t necessarily only a suspensory story.

Why do this back shape, hock issues, suspensory strain and SI dysfunction seem to turn up together in so many horses?

𝗜 𝗱𝗼𝗻’𝘁 𝘁𝗵𝗶𝗻𝗸 𝗶𝘁’𝘀 𝗰𝗼𝗶𝗻𝗰𝗶𝗱𝗲𝗻𝗰𝗲.

And I don’t think we can keep looking at the hock, the suspensory or the SI region as though each exists in its own little box.

𝗬𝗼𝘂𝗿 𝗵𝗼𝗿𝘀𝗲 𝗵𝗮𝘀 𝗮 𝗵𝘂𝗻𝘁𝗲𝗿'𝘀 𝗯𝘂𝗺𝗽. 𝗕𝘂𝘁 𝗶𝘀 𝗮𝗻𝘆𝗼𝗻𝗲 𝗹𝗼𝗼𝗸𝗶𝗻𝗴 𝗽𝗮𝘀𝘁 𝗶𝘁⁉️

Most horse owners recognise a "hunter's bump".

You look across the top of the pelvis and the tubera sacrale appear prominent. Also close together. Sometimes there's a deep groove between them and the whole top of the pelvis seems to stand out.

But in some horses, that visible shape is only one part of a much bigger pattern.

There is a severe pelvic presentation called a 💥depressed sacrum💥

❗️𝗧𝗵𝗶𝘀 𝗶𝘀 𝗻𝗼𝘁 𝘀𝗶𝗺𝗽ly 𝗮𝗻 𝗦𝗜 𝗷𝗼𝗶𝗻𝘁 𝘁𝗵𝗮𝘁 𝗵𝗮𝘀 𝗹𝗼𝘀𝘁 𝗮 𝗹𝗶𝘁𝘁𝗹𝗲 𝗺𝗼𝗯𝗶𝗹𝗶𝘁𝘆/𝘀𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆.

It is a significant positional disorder of the sacrum in relation to the two ilia, and once that relationship changes, the rest of the body has to reorganise around it.

🟣 The compensation chain, in one line:
𝗦𝗔𝗖𝗥𝗨𝗠 → 𝗟𝗨𝗠𝗕𝗔𝗥 𝗦𝗣𝗜𝗡𝗘 → 𝗧𝗛𝗢𝗥𝗔𝗖𝗢𝗟𝗨𝗠𝗕𝗔𝗥 𝗝𝗨𝗡𝗖𝗧𝗜𝗢𝗡 → 𝗧𝗛𝗢𝗥𝗔𝗫 → 𝗗𝗜𝗔𝗣𝗛𝗥𝗔𝗚𝗠 → 𝗦𝗛𝗢𝗨𝗟𝗗𝗘𝗥𝗦 → 𝗙𝗜𝗥𝗦𝗧 𝗥𝗜𝗕 → 𝗖𝗘𝗥𝗩𝗜𝗖𝗔𝗟 𝗦𝗣𝗜𝗡𝗘 → 𝗧𝗠𝗝

That's where it gets interesting.

Look first at the hindquarter.

The top of the pelvis can develop a very characteristic appearance, with a deep groove around the tubera sacrale.

The muscle pattern can become equally obvious. You may see overdeveloped, ropey or heavily loaded muscle through parts of the gluteal and hamstring region, while other areas lose normal volume and support.

So when I see a big muscle, I do not automatically think: strong muscle.

Sometimes a muscle is big because it is doing far too much.

The question is always: why has the horse needed to build that pattern?

Now follow it through the hindlimbs and spine.

In the depressed-sacrum pattern, the hindlimbs can rotate outwards. The sacrococcygeal region can be held in hyperextension. The caudal lumbar spine can move into hyperextension as well, while the thoracolumbar junction compensates in the opposite direction and moves into increased flexion.(roach)

Then the pattern moves further forwards.

The thoracic spine may become hyperextended. The respiratory diaphragm can become held towards an inspiratory position.

And that is not a trivial detail.

The diaphragm is not just a breathing muscle. It's part of the pressure system between the thorax and abdomen. It's attached into the sternum, ribs and lumbar region, and it has direct relationships with the pleural, vascular and visceral systems around it.

If the diaphragm becomes maintained towards inspiration, pressure relationships within the thoracic and abdominal cavities change. That can alter the movement of the viscera, the mechanics of the ribs and thorax, and the way blood and lymph move through the body.

In this depressed-sacrum pattern, the consequences described include congestion through the limbs, thorax, abdomen and head, reduced ventilation of the lungs, and altered blood flow to and from the heart. The visceral consequences can include altered support of the pelvic organs and functional disturbance of the viscera.

And then there is the autonomic component.

Irritation around the stellate ganglion is described as contributing to endocrine imbalance. Strain through the craniosacral system is associated with changes in vitality, immune function and behaviour.

So suddenly we are a very long way from: "my horse has a bump over its SI."

And we still haven't finished following the mechanical pattern.

One of the particularly recognisable changes described with a depressed sacrum is a deep, square-shaped hollow behind the withers and shoulders. Further forwards again, the cervical spine can move into overextension. The splenius, rhomboid and serratus musculature can lose normal bulk. The shoulders can become restricted. The first rib becomes part of the compensatory pattern. And the TMJ can lose mobility.

That is why this pattern is so valuable to understand.

Not because every horse with a hunter's bump has a depressed sacrum. They do not.

And not because every horse with an SI dysfunction develops this severe presentation. They do not.

But a depressed sacrum gives us an extreme, very clear example of what compensation really looks like - and compensation throughout the whole horse does happen without a depressed sacrum too.

If the pelvis can no longer manage force normally, the horse does not stop functioning. It adapts. The lumbar spine changes. The thorax changes. The diaphragm changes. The shoulders change. The neck changes. The jaw changes. The autonomic system becomes involved. The vascular and visceral systems become involved.

𝗧𝗵𝗲 𝗵𝗼𝗿𝘀𝗲 𝗶𝘀 𝘀𝘁𝗶𝗹𝗹 𝗼𝗻𝗲 𝗯𝗼𝗱𝘆.

And this is exactly why simply treating the place that looks worst is rarely the whole story.

A large hamstring may not need strengthening. A hollow behind the shoulder may not be a saddle problem. A stiff neck may not begin in the neck. A restricted jaw may not begin at the jaw.

Sometimes those things are the evidence of the compensation, not the origin of it.

And that is the question I keep coming back to: what has the rest of the horse had to change in order to accommodate the pelvis?

The treatment strategy for this severe pattern reflects that. It does not stop at the SI region. It includes work through the diaphragms, respiratory diaphragm, TMJ, first rib and front limbs, as well as reducing strain through the sacrum and coccygeal region.

🐎 Because once the compensation has become whole-body, the treatment thinking has to become whole-body too.

The depressed sacrum is an extreme example and deserves its own teaching in much greater depth. But it demonstrates one of the most important principles: the compensation does not stop where the dysfunction started.

💕 So if your horse has a hunter's bump, don't just stare at the bump. Look at the hindquarter. Look at the muscle pattern. Look at the lumbar spine. Look behind the withers. Look at the shoulders. Look at the neck. 𝗟𝗼𝗼𝗸 𝗮𝘁 𝘁𝗵𝗲 𝘄𝗵𝗼𝗹𝗲 𝗵𝗼𝗿𝘀𝗲.

Because sometimes the most important thing about the bump is not the bump at all. It's everything the horse has had to change around it. Most importantly to help these horses the WHOLE horse needs assessing.

“My horse is tight through his back.”
“She has an SI problem.”
“He’s always restricted through his poll.”
“She’s tight behind the shoulder.”

These observations may all be completely valid

But the area where you find the problem isn’t necessarily where the problem began.

And this is where treating an area and treating the horse can become two very different things.

If I find restriction through the lumbar spine, I could simply work on the lumbar spine. But why is it restricted?

Is the sacrum influencing the lumbar mechanics?

Is the pelvis compensating for something happening lower down the limb?

What is the diaphragm doing?

Are the ribs moving normally?

Is there altered tension through the fascial system?

Could there be a visceral influence?

What is happening with vascularity and neurological input to the area?

And what has the rest of the horse had to change to accommodate it?

𝗧𝗵𝗲 𝗯𝗼𝗱𝘆 𝗱𝗼𝗲𝘀𝗻'𝘁 𝗳𝘂𝗻𝗰𝘁𝗶𝗼𝗻 𝗮𝘀 𝗮 𝗰𝗼𝗹𝗹𝗲𝗰𝘁𝗶𝗼𝗻 𝗼𝗳 𝘀𝗲𝗽𝗮𝗿𝗮𝘁𝗲 𝗽𝗮𝗿𝘁𝘀.
❌ The pelvis doesn't stop at the pelvis.
❌ The spine doesn't work independently of the ribs.
❌ The jaw isn't disconnected from the neck.The musculoskeletal system isn't separate from the nervous, vascular, fascial, or visceral systems.

Everything is adapting to everything else.

So if we repeatedly find ourselves treating the same “tight” area, it is worth asking a different question:

𝗪𝗵𝘆 𝗱𝗼𝗲𝘀 𝘁𝗵𝗲 𝗵𝗼𝗿𝘀𝗲 𝗸𝗲𝗲𝗽 𝗻𝗲𝗲𝗱𝗶𝗻𝗴 𝘁𝗵𝗮𝘁 𝗮𝗿𝗲𝗮 𝘁𝗼 𝗯𝗲 𝘁𝗶𝗴𝗵𝘁? 𝗦𝗼𝗺𝗲𝘁𝗶𝗺𝗲𝘀 𝘁𝗲𝗻𝘀𝗶𝗼𝗻 𝗶𝘀 𝗻𝗼𝘁 𝘁𝗵𝗲 𝗽𝗿𝗼𝗯𝗹𝗲𝗺.

Sometimes it is the body's solution to another problem.That is one of the fundamental differences in an osteopathic approach. I'm not simply looking for "what can I release?"

I'm looking for: 𝗪𝗵𝗮𝘁 𝗽𝗮𝘁𝘁𝗲𝗿𝗻 𝗵𝗮𝘀 𝘁𝗵𝗶𝘀 𝗵𝗼𝗿𝘀𝗲 𝗰𝗿𝗲𝗮𝘁𝗲𝗱 - 𝗮𝗻𝗱 𝘄𝗵𝘆?

Ultimately, the aim isn't to make one area move better for a few days. It is to give the horse's whole system the best opportunity to move, regulate, and function better as a whole. 🌟

Because the diaphragm is not simply a breathing muscle sitting quietly at the back of the rib cage.❣️

And if you followed my last post about the horse that has a supposedly “good rein” and “bad rein”, this is where that story starts to get even more interesting.

We talked about the horse that continually organises itself around/loads into the same shoulder. On one rein it motorbikes into it. On the other, it appears to bend beautifully but actually overbends and loses that same shoulder to the outside. Meaning that same shoulder is a dominant loading shoulder.

We also started looking underneath that apparently simple shoulder problem at the first rib and thoracic inlet.

But there is another structure in that conversation that most riders would never associate with a horse falling onto one shoulder:

𝗧𝗵𝗲 𝗿𝗲𝘀𝗽𝗶𝗿𝗮𝘁𝗼𝗿𝘆 𝗱𝗶𝗮𝗽𝗵𝗿𝗮𝗴𝗺

Most of us think about the diaphragm in one context: breathing or inspiration.

💣 But anatomically, the diaphragm sits in the middle of a much bigger mechanical and neurological conversation.

🦴 It attaches into the sternum, ribs and lumbar region, separating the thoracic and abdominal cavities. The aorta, oesophagus and caudal vena cava all pass through it.

So immediately we are dealing with something that sits between the back, ribs, thorax, abdomen and circulation.

But the relationship that really interests me begins much further forwards.

𝗧𝗵𝗲 𝗽𝗵𝗿𝗲𝗻𝗶𝗰 𝗻𝗲𝗿𝘃𝗲.❗️

The phrenic nerve arises from the mid cervical region and travels caudally through the neck alongside the ventral scalene muscle.

And that matters because the ventral scalene attaches directly onto the first rib.

The phrenic nerve is usually introduced as the motor nerve to the diaphragm, and of course that is hugely important.

But it is not only motor.

It also carries sensory information associated with structures including the pericardium, pleura, diaphragm and peritoneum.

So this nerve travelling from the neck towards the diaphragm is not simply carrying the motor drive for diaphragm contraction. It is also part of the sensory conversation coming back from some major thoracic and abdominal structures.

That immediately gives us a fascinating anatomical relationship between the mid cervical region, first rib and thoracic inlet, pleural and pericardial structures, diaphragm and peritoneal environment.

𝗔𝗻𝗱 𝗿𝗲𝗺𝗲𝗺𝗯𝗲𝗿 𝘄𝗵𝗲𝗿𝗲 𝘁𝗵𝗮𝘁 𝗻𝗲𝗿𝘃𝗲 𝗶𝘀 𝘁𝗿𝗮𝘃𝗲𝗹𝗹𝗶𝗻𝗴.

💫 The scalene muscles are involved in neck mechanics, first rib elevation and respiration. So before the phrenic nerve has even reached the thorax, we already have a relationship involving the mid cervical spine, scalenes, first rib and thoracic inlet. 🤯

The phrenic nerve then passes through the thoracic inlet in close relationship with the subclavian artery and vein, before continuing through the thorax towards the diaphragm.

So the nerve supplying your horse’s major respiratory muscle begins in the neck and travels through the very same first rib and thoracic inlet region we were discussing in relation to the shoulder.

❗️𝗧𝗵𝗮𝘁 𝗶𝘀 𝗮 𝗰𝗼𝗻𝗻𝗲𝗰𝘁𝗶𝗼𝗻 𝘄𝗼𝗿𝘁𝗵 𝗿𝗲𝗺𝗲𝗺𝗯𝗲𝗿𝗶𝗻𝗴.

Because the thoracic inlet is not empty space.

It is a compact gateway between the neck and thorax, with major structures continuing towards the forelimb.

Through this region travel neural, vascular and lymphatic structures. The first rib forms an important part of its boundary.

Think about what is meeting in this relatively small area:

🔹 first rib
🔹 scalene muscles
🔹 lower cervical region
🔹 brachial plexus
🔹 subclavian vascular pathway
🔹 phrenic nerve
🔹 pleural structures

This is why the geometry and mobility of the first rib and scalene region are so interesting osteopathically.

There is another reason the diaphragm belongs in a conversation about movement.

At faster gaits, breathing and locomotion in the horse become closely coupled. At canter and gallop, horses commonly synchronise the respiratory cycle with the stride cycle, often approaching one breath for each stride.

That tells us something important.

𝗕𝗿𝗲𝗮𝘁𝗵𝗶𝗻𝗴 𝗮𝗻𝗱 𝗹𝗼𝗰𝗼𝗺𝗼𝘁𝗶𝗼𝗻 𝗮𝗿𝗲 𝗻𝗼𝘁 𝘁𝘄𝗼 𝗰𝗼𝗺𝗽𝗹𝗲𝘁𝗲𝗹𝘆 𝘀𝗲𝗽𝗮𝗿𝗮𝘁𝗲 𝘀𝘆𝘀𝘁𝗲𝗺𝘀 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗻𝗴 𝗯𝗲𝘀𝗶𝗱𝗲 𝗼𝗻𝗲 𝗮𝗻𝗼𝘁𝗵𝗲𝗿.

The movement of the limbs, thorax, abdominal contents and diaphragm are mechanically interacting during locomotion.

So when we talk about diaphragm mobility, rib mobility and thoracic mechanics, we are not only talking about what happens while the horse stands quietly breathing in the stable.

We are talking about a system that has to organise itself rhythmically while the horse is moving.

And then there is the neurological side of the front end.

Equine research has shown that compression affecting the caudal cervical nerve roots can produce forelimb lameness, and that the severity may vary depending on things such as rein, head position and work under saddle.

That should make every rider and bodyworker think.

Because suddenly the horse that feels different on one rein, changes with head position or repeatedly organises itself around one shoulder may be giving us information about a much more complex region than the shoulder alone.

That does not mean every horse with those signs has nerve compression.

It means the anatomy gives us another question to ask.

And there is still another layer.

𝗧𝗵𝗲 𝗱𝗶𝗮𝗽𝗵𝗿𝗮𝗴𝗺 𝗮𝗹𝘀𝗼 𝗵𝗮𝘀 𝗺𝗲𝗰𝗵𝗮𝗻𝗶𝗰𝗮𝗹 𝗿𝗲𝗹𝗮𝘁𝗶𝗼𝗻𝘀𝗵𝗶𝗽𝘀 𝗳𝗼𝗿𝘄𝗮𝗿𝗱𝘀 𝘁𝗵𝗿𝗼𝘂𝗴𝗵 𝘁𝗵𝗲 𝗽𝗹𝗲𝘂𝗿𝗮𝗹 𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲𝘀.

Within the osteopathic model I was trained in, the pleural dome and its suspensory relationships connect back towards the lower cervical region, T1 and the first rib.

So we can start following a relationship that looks something like:

𝗖𝗘𝗥𝗩𝗜𝗖𝗔𝗟 𝗥𝗘𝗚𝗜𝗢𝗡 → 𝗦𝗖𝗔𝗟𝗘𝗡𝗘𝗦 → 𝗙𝗜𝗥𝗦𝗧 𝗥𝗜𝗕 → 𝗧𝗛𝗢𝗥𝗔𝗖𝗜𝗖 𝗜𝗡𝗟𝗘𝗧 → 𝗣𝗛𝗥𝗘𝗡𝗜𝗖 𝗡𝗘𝗥𝗩𝗘 → 𝗗𝗜𝗔𝗣𝗛𝗥𝗔𝗚𝗠

And if you follow the mechanical relationships back the other way:

𝗗𝗜𝗔𝗣𝗛𝗥𝗔𝗚𝗠 → 𝗧𝗛𝗢𝗥𝗔𝗫 → 𝗙𝗜𝗥𝗦𝗧 𝗥𝗜𝗕 → 𝗕𝗔𝗦𝗘 𝗢𝗙 𝗡𝗘𝗖𝗞 → 𝗦𝗛𝗢𝗨𝗟𝗗𝗘𝗥 𝗥𝗘𝗚𝗜𝗢𝗡

This is why the diaphragm is not “just about breathing”.

Its movement is part of thoracic mechanics, rib motion and pressure change with every single breath.

And if one part of that system has lost mobility, the body does what horses are exceptionally good at doing.

It adapts.

That adaptation may appear somewhere completely different from where it started.

This is also why I am very cautious about simple recipes.

Horse loads one shoulder? Treat the shoulder.

First rib feels restricted? Treat the first rib.

Diaphragm feels restricted? Release the diaphragm.

That is not the point.❣️

⁉️The important question is:

𝗪𝗵𝘆 𝗶𝘀 𝘁𝗵𝗮𝘁 𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝗵𝗮𝘃𝗶𝗻𝗴 𝘁𝗼 𝗯𝗲𝗵𝗮𝘃𝗲 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁𝗹𝘆?

⚠️This is where direct testing matters.

Looking at the horse gives us a hypothesis. The rider’s description adds another layer. Posture and movement give us more clues. But then the structures themselves have to be assessed for mobility.

The first rib should move with respiration.

The thorax should move.

The diaphragm should move.➡️ ( remember the relationship with the sacrum in webinar 2.).....

& The cervical region should be able to adapt.

Sometimes what appears to be a shoulder pattern turns out to have relationships much further through the horse.

Which brings us straight back to the pelvis.

Because if the horse has already had the SI/pelvis treated and genuinely feels better behind, but continues to use exactly the same established front end pattern, perhaps the original dysfunction has changed while some of the compensations built around it are still very well practised.

𝗔𝗻𝗱 𝘁𝗵𝗶𝘀 𝗶𝘀 𝘄𝗵𝗲𝗿𝗲 𝗪𝗲𝗯𝗶𝗻𝗮𝗿 𝟯 𝗶𝘀 𝗴𝗼𝗶𝗻𝗴.

We started in webinar 1 with the SI joint and pelvis.

Now we are following what happens as we travel forwards through the horse, into the thorax, diaphragm, first rib, cervical region and beyond.

Webinar 3 is not another webinar about treating the SI joint. It is about understanding why the SI joint never existed in isolation in the first place.

Details and booking will follow shortly.

For now, next time your horse repeatedly falls onto the same shoulder, ask yourself one more question:
