🐴💩📣𝐀𝐍𝐍𝐔𝐀𝐋 𝐑𝐄𝐏𝐎𝐒𝐓📣💩🐴

We’re halfway through February, which means it is nearly March, which means it is almost “autumn”, which means it's time for this annual post, to catch you all before you drench your horses on the 1st of March.

Mid - late autumn is the No. 1 time of year to worm your horses, because it ties in best with breaking the bot-fly life cycle. A bot fly’s lifecycle is 12 months, so treating just once a year will break that lifecycle (and overtime decrease bot fly populations). By mid-autumn/early winter, the entire population of bot flies will be inside your horse, which means you can target all the bots on your property with a single dosage of a boticide dewormer (ivermectin, abamectin, moxidectin).

If you deworm your horses too early in autumn, you will not be targeting all the bot flies as they are often present well into autumn, laying eggs on your horses coat. If you deworm on the 1st of March, there will be bot flies, and subsequently bot eggs and larvae that come after the treatment and will remain within your horse for the year.

Therefore, hold off on the autumn deworming a little longer, if your horses are in good condition. Wait until the nights cool down and the bot flies disappear before deworming – and make sure that the dewormer you purchase is active against bots, otherwise it will all be in vain. If your horses need to be treated now, do so, but make sure you target bot flies again in early winter. The “first frost” method simply means it is cold enough that the bots will be finished. Australia frosts are not cold enough to actually kill any worms in the ground – these need consistent days of below zero temperatures (think Northern European/American winters)

So that’s my bot-fly spiel. Normally I write about strongyles (my favourite), and so I shall of course make a mention of them here too.
I always recommend a mid-late autumn deworming for ALL HORSES because it a) cleans out any bots and b) all horses really should have a strongyle clean out once a year as well. I may be against deworming for the sake of deworming, however that is only if you are doing it 3 or 4 or more times a year.

Strongyles can have a lifecycle of as little as 6 weeks. In addition, at any one point, about 90% of the strongyle population is living on the pasture, not in the horse. Therefore, the concept of using chemical dewormers inside the horse to break the lifecycle of strongyles would not work. At all. So, we chose our annual deworming-clean-out to line up with as many other parasites as possible.

All boticide dewormers are also effective against strongyles so deworming in autumn is a 2 for 1 type deal. You should also consider using a dewormer that also contains praziquantel to treat for tapeworms to get a complete clean out, just in case tapeworms are present. WormCheck does offer a tapeworm specific FEC now, if you wanted to check beforehand to avoid the overuse of praziquantel. (There have been some scary reports of praziquantel resistance in Europe.)

Lastly… wait, second lastly.. this is a topic too complex to get into here, but: this time of year is key for larval cyathostomins, where encysted larvae have mass emergences from the intestine wall, in response to changes in weather (e.g. in VIC as it cools and becomes wetter again). Deworming and removing adult populations of worms can act as a trigger for larval re-emergence, which is also why I often baulk at deworming horses now. The larvae may slowly re-emerge coming into the cooler weather and treating in mid-late autumn may be a safer bet to remove adults and emerged larvae. The research on this is sketchy as best, however these are patterns shown in cattle and hypothetically should translate over into horses.

And lastly (pat on the back for reading this far): just because I’m recommending deworming all horses does not mean I am not recommending FECs in autumn. A FEC will tell you important things about your horses health, and pick up anything odd that may be happening (e.g. a spike in EPG in a horse that is usually a low shedder; this is a sign of an impaired immune system, e.g. EMS, cushings). Doing an autumn FEC will also allow you to test drug efficacy. Autumn should be a key time for everyone to do a FECRT (faecal egg count reduction test), where you get FECs done before and after deworming to make sure that it worked. If you only deworm once a year, then you’ve only got one chance for a FECRT, and you cannot, I repeat, you CANNOT do a FECRT without a FEC before to compare to.

If you’d like to organise FECs and FECRTs for your horses this autumn, check out the website (link on the FB page) for postal submission and drop off points/events.

I’m going to do a series tackling some of the main hind end joints starting off with the STIFLE!!

The equine stifle is arguably one of the most biomechanically complex and misunderstood joints in the horse’s body.

Up to approximately 40% of sport-related orthopedic injuries involve the stifle.

The stifle is anatomically comparable to the human knee. However, unlike the human knee, the equine stifle must stabilize and generate propulsion for a 1,000+ lb animals!! It is an incredibly important structure to not only understand, but also appreciate its role. The stifle connects the femur to the tibia, meeting with the patella.

𝑀𝑒𝑑𝑖𝑎𝑙 𝑎𝑛𝑑 𝑙𝑎𝑡𝑒𝑟𝑎𝑙
𝐌𝐞𝐧𝐢𝐬𝐜𝐢
𝑀𝑒𝑑𝑖𝑎𝑙 𝑎𝑛𝑑 𝑙𝑎𝑡𝑒𝑟𝑎𝑙

There’s a lot to it. Let’s break this down a little bit.

𝐌𝐄𝐍𝐈𝐒𝐂𝐈
The menisci absorb shock and improve congruency (how well the joint surfaces fit together) between the femur and tibia. Overall, they are super important in distributing force and reducing friction.

𝐅𝐫𝐢𝐜𝐭𝐢𝐨𝐧 -> 𝐇𝐞𝐚𝐭 -> 𝐈𝐧𝐟𝐥𝐚𝐦𝐦𝐚𝐭𝐢𝐨𝐧 -> 𝐏𝐚𝐢𝐧

The medial meniscus is less flexible, leading to increased susceptibility to injury than the lateral meniscus.
Ultrasonography and radiology is limited on its full capability to view early soft tissue stifle lesions.

Incidence of meniscal injury ranges from about 35-70% of horses evaluated arthroscopically. (e.g., Walmsley et al., 2003; Cohen et al., 2009, Equine Veterinary Journal).

Those numbers matter.
But understanding why stifles are frequently missed is just as important. We’ll come back to this.

𝐂𝐑𝐔𝐂𝐈𝐀𝐓𝐄 𝐋𝐈𝐆𝐀𝐌𝐄𝐍𝐓𝐒
These cross inside the joint like an “X” preventing forward or backward sliding of the tibia relative to the femur.

𝐂𝐎𝐋𝐋𝐀𝐓𝐄𝐑𝐀𝐋 𝐋𝐈𝐆𝐀𝐌𝐄𝐍𝐓𝐒
These run along the inside and outside of the joint and prevent instability from side to side.

The stifle does not function in isolation. It is mechanically linked to the hip and hock through the reciprocal apparatus.

Basically -
Flexion of the stifle = flexion of the hock
Extension of the stifle = extension of the hock

Hock pathology can overload the stifle. Stifle instability can present as hock soreness. This is why hind end lameness can be so difficult to isolate. Because truly, they all work together. Overtime they all become somewhat affected.

How often do you need to inject both hocks and stifles?
It’s two of the most commonly injected joints. Because they work so interconnected.

𝐏𝐞𝐥𝐯𝐢𝐬 -> 𝐒𝐭𝐢𝐟𝐥𝐞 -> 𝐇𝐨𝐜𝐤 -> 𝐅𝐞𝐭𝐥𝐨𝐜𝐤 -> 𝐇𝐨𝐨𝐟

Instability or pain of one redistributes load throughout the chain.

Restriction or pain at the stifle can create compensatory tension patterns moving up to the sacroiliac (SI) region, lumbar spine (low back), hocks…all the way to the front end.

Okay so what’s happening in motion?

𝐖𝐀𝐋𝐊
• Some flexion and extension

𝐓𝐑𝐎𝐓
• Increased flexion
• Higher compressive forces of femorotibial

𝐋𝐎𝐏𝐄
• Peak flexion during swing phase
• Peak extension during push off
• Significant forces across menisci and cruciates

When a horse turns, especially at speed, the inside hind has to do more work than the outside. As that inside leg plants and pushes off the ground, the lower leg (the tibia) rotates slightly inward compared to the upper leg (the femur).

In simpler terms, the lower leg twists inward under load while also asking it to support more weight AND be a huge part of the powerhouse of the hind end. This entire process creates significant additional stress on the medial stifle, such as the menisci and cruciate ligaments.

The medial femorotibial joint is therefore the most commonly affected in performance horses. Barrel racing, cutting and reining are great examples. Repetitive compressive loading combined with rotational torque leads to progressive strain on cartilage, menisci, and supporting ligaments.

The surrounding muscles are extremely important to support the stifle. I talked about how important this is in the long trotting post and TFL post. This stifle NEEDS the support from the surrounding muscles.

Dynamic stability of the stifle depends heavily on the quadriceps and hamstring groups. The primary stifle extensors (straighten the leg) are the quadriceps femoris, while the primary flexors (bend the leg) include the biceps femoris, semitendinosus, semimembranosus, and gastrocnemius.

When muscular function decreases, whether from fatigue, atrophy, weakness, delayed neuromuscular firing, or pain inhibition… the joint loses active stabilization.

Lets circle back around to this cycle -

𝐅𝐫𝐢𝐜𝐭𝐢𝐨𝐧 -> 𝐇𝐞𝐚𝐭 -> 𝐈𝐧𝐟𝐥𝐚𝐦𝐦𝐚𝐭𝐢𝐨𝐧 -> 𝐏𝐚𝐢𝐧. 𝑹𝑬𝑷𝑬𝑨𝑻.

**Add in an increased susceptibility to arthritic changes, bony changes, cartilage damage, and/or soft tissue injury**

Remember how connected the hind end is?

If the pelvis lacks stability, the stifle absorbs more rotational demand.
Or, primary stifle pain reduces hindlimb protraction (forward reach of the hind limb), which increases compensatory stress in the lumbar spine and sacroiliac region. The rest of the limb will eventually take the fall with the original culprit. The entire kinetic chain adjusts.

We see subtle performance changes -
• Hesitation to move forward
• Reluctance to load the inside hind limb in turns
• Shortened stride
• “Bunny hopping” through a turn
• Uneven hind hoof patterns
• Committing to a turn then running by

As strain progresses, the compensations become more apparent -
• Shortened cranial phase of stride (reduced forward reach)
• Difficulty engaging from behind
• “Flat” in a run
• Cross firing
• Struggles to collect
• Delayed or weak push off

The reality is this many stifle injuries begin as subtle instability, neuromuscular inhibition, or progressive overload. Early imaging can miss soft tissue changes. The stifle is a difficult area to image. And if the surrounding musculature is not conditioned properly to support and stabilize it, the soft tissue structures (including the joint) will take the strain.

If we want longevity, we cannot just treat the inflammation.

We HAVE to build stability before it fails.

Why Hands On Massage Is The Best Way To Care For Sore Muscles

I often see people posting about their horse having muscle knots and being muscle sore, talking about having the chiropractor out, Pemf and red light, kt tape, vet’s been out and still the horse is not better, why?

My question is; why are you doing everything you can think of to help your horse feel better EXCEPT the one thing that actually addresses those sore, tight muscles directly?!
Other therapies are NOT stand-ins or substitutes for massage – they do different things for the horse.

Massage is the only one of these therapies that physically manipulates the muscles, fascia and skin to ease tight, sore muscles lengthen and supple myofascia, free painful nerves, improve circulation, increase range of motion and bring balance and biotensegrity back to the body to improve performance and soundness.

An equine massage therapist uses their hands to feel and carefully manipulate the soft tissues to work out tension, knots, kinks and adhesions. Massage manually opens myofascial tissue, softening, stretching, balancing tension, improving range of motion and freedom of movement of muscle, fascia, joints and skin.
Massage speeds muscle healing. The micro tears and trigger points caused by exercise and building muscles heal faster, stronger and with a healthier range of motion when your horse receives regular massage sessions.

Tight, tense and fatigued muscles increase the risk of tendon injuries. Tendons are an extension of the muscle and anchor the muscle to the bone. If the muscle is impaired, the tendon will also be, which greatly raises the risk of injury. Massage can improve the health and function of the muscles and tendons to help ward off injuries.

Massage techniques with different frequencies, amplitudes and intensities can improve athleticism by stimulating the mechanoreceptors and improving the horse’s proprioception (awareness of position) and kinesthesia (movement in the body), helpful when improving the horse’s overall athleticism. This will also help stimulate healing if the horse has suffered a neurological insult.

Massage physically stimulates weak and inactive muscles to help bring them back into action.
Pain and tension interfere with the body’s ability to recover from illness or injury and will extend recovery time. Many veterinarians have begun to incorporate massage therapy into their recovery protocols as an effective, natural way to aid in pain regulation and recovery for both acute and chronic issues. Equine Massage therapists are trained to work on soft tissues to alleviate pain and improve the body’s ability to heal itself.

Massage physically pumps and presses circulation into congested areas, opening them to better nourishment, oxygenation and hydration all of which optimize healing and healthy tissue development and performance.

Massage increases the production of mitochondria, responsible for powering the production of ATP in cellular metabolism. More mitochondria lead to more ATP, which means increased energy to heal. Massage also increases levels of white blood cells which attack viruses and bacteria.

Massage increases the production of cytokines, chemical messengers that work for the immune system to regulate things like fever, pain and inflammation.

Massage releases endorphins which act as a natural analgesic helping to relieve headaches, myofascial pain, muscle soreness, TMJ, and other discomforts and a lasting sense of well-being.

A full-body massage can improve digestion by increasing the release of enzymes essential for healthy digestion and stimulating the motion of the intestine, and its contents, to move along.
Regular massage can retrain the body to move more readily into the parasympathetic state, the state in which the body is able to relax, digest and repair. This can be especially helpful for high strung, spooky or recovering horses.

Massage is one of, if not the, most effective muscle and myofascial therapies available and it can be customized to meet each horse’s physical needs. Leaving it out of your regular care and exercise routine leaves a huge hole and a missed opportunity.

One of the most consistent compensatory patterns I assess in horses is the same-side relationship between the TMJ (temporomandibular joint) and the ilium.

𝘛𝘩𝘪𝘴 𝘪𝘴𝘯’𝘵 𝘤𝘰𝘪𝘯𝘤𝘪𝘥𝘦𝘯𝘤𝘦.

The 𝗶𝗹𝗶𝘂𝗺 forms part of the pelvic component of the 𝘀𝗮𝗰𝗿𝗼𝗶𝗹𝗶𝗮𝗰 𝗷𝗼𝗶𝗻𝘁 (𝗦𝗜𝗝) > a structure that plays a critical role in force transfer from the hindlimbs through the lumbar spine and into the trunk.

The 𝗧𝗠𝗝 sits at the top of a fascial and neurological system that influences the poll, cervical spine and thoracolumbar junction. Restrictions here alter tension patterns throughout the axial skeleton. Those patterns do not stop at the withers, they continue caudally into the pelvis.

So:

• Jaw restriction can contribute to pelvic dysfunction
• Iliac/SI restriction can reinforce jaw asymmetry

It is also why a true 𝘄𝗵𝗼𝗹𝗲-𝗵𝗼𝗿𝘀𝗲 evaluation matters. If we focus only on the site of obvious pain or performance loss, we miss the driver behind it.

In practice, this is why I collaborate closely with farriers, dental professionals and veterinary colleagues.

If your horse is showing performance changes, hind-end weakness, asymmetry, resistance in the contact, or recurring SI concerns, it may be time to look beyond the obvious area.

𝘈𝘯𝘥 𝘵𝘩𝘪𝘴 𝘯𝘢𝘵𝘶𝘳𝘢𝘭𝘭𝘺 𝘭𝘦𝘢𝘥𝘴 𝘵𝘰 𝘵𝘩𝘦 𝘯𝘦𝘹𝘵 𝘲𝘶𝘦𝘴𝘵𝘪𝘰𝘯…

If the 𝗶𝗹𝗶𝘂𝗺 is so influential > and if its relationship with the 𝗧𝗠𝗝 is this significant, how thoroughly are we really assessing the 𝘀𝗮𝗰𝗿𝗼𝗶𝗹𝗶𝗮𝗰 𝗿𝗲𝗴𝗶𝗼𝗻?

Because the SI joint is not just “the SI.”

● It is the articulation between sacrum and ilium.

● It is a load-transfer junction.

● It is a motion-dependent structure.

In the next post, I’ll break down why properly assessing the sacrum and ilium, rather than simply labelling “𝗦𝗜 𝗷𝗼𝗶𝗻𝘁 𝗽𝗮𝗶𝗻” > can completely change outcomes.

Histamine Response to Massage, Touch, and Stroking

Why Skin Changes, Twitching, and Warmth Happen During Bodywork

One of the most immediate and visible effects of massage or tactile contact is a change in the skin. Hair may ripple. A region may grow warm. Pinkness can appear in light-skinned horses. A muscle may twitch or the horse may suddenly turn to look at the area.

These reactions are often attributed to “increased circulation,” which is true — but it is only part of the story.

Behind many of these rapid changes is the release of histamine, a powerful signaling molecule stored inside mast cells throughout connective tissue.

Understanding this response helps explain how simple touch can rapidly influence vascular flow, nerve activity, and tissue behavior.

What Is Histamine?

Histamine is a normal biochemical messenger involved in:
• immune defense
• inflammatory regulation
• vascular control
• neural communication

It is stored primarily in mast cells, which are abundant in fascia, skin, and around blood vessels.

When tissue experiences mechanical stimulation — pressure, stretch, friction, or temperature change — mast cells can release histamine into the surrounding environment.

This is not automatically a sign of pathology.
It is a fundamental part of how the body responds to mechanical input.

What Histamine Does After Release

Vasodilation

Histamine causes small blood vessels to widen.

This produces:
• increased local blood flow
• warmth
• visible color change in lighter skin
• faster delivery of oxygen and nutrients

This effect is one of the reasons tissue texture can soften quickly during a session.

Increased Vascular Permeability

Histamine makes vessel walls more permissive, allowing fluid and biochemical messengers to move between circulation and tissue.

In healthy situations and with appropriate pressure, this supports:
• metabolic exchange
• removal of waste products
• restoration of tissue chemistry

Sensory Nerve Activation

Histamine also stimulates nearby nerve endings.

The result may include:
• twitch responses
• skin rippling
• tail swishing
• the horse looking toward the contact point

Importantly, this is not always pain.
It is frequently a sign of neurological awareness and communication.

The “Triple Response” Concept

Firm stroking of the skin classically produces:
1. a red line
2. a surrounding flare
3. sometimes a small raised area

This reaction demonstrates the integrated behavior of capillaries, nerves, and mast cell signaling.

It is one of the clearest examples of touch translating into chemistry.

Why This Matters in Fascial and Myofascial Work

Fascia contains a rich population of mast cells.
Because of this, it is highly responsive to mechanical input.

Histamine release is part of a rapid cascade that can lead to:
• changes in fluid distribution
• altered sliding between layers
• modification of resting tone
• shifts in proprioceptive signaling

This is one reason skilled touch can create noticeable change within minutes.

The process is not purely mechanical.
It is mechanical → chemical → neurological.

What Practitioners Commonly Observe in Horses

During or after treatment, you may see:
• localized warmth
• patchy sweating
• uneven coat coloration
• relaxation or softening of muscle
• changes in posture or weight bearing

Some horses exhibit dramatic visible reactions.
Others show very subtle ones.

Variation does not necessarily indicate treatment quality; it reflects individual sensitivity and physiology.

Helpful vs. Excessive Responses

A mild histamine response is normal and often beneficial.

Stronger reactions may occur in horses with:
• allergic tendencies
• heightened skin reactivity
• underlying inflammatory conditions
• compromised tissue resilience

In those situations, welts or prolonged swelling may appear, and pressure or technique should be adjusted.

The Bigger Picture

Histamine is often thought of only in the context of allergy or inflammation.
In bodywork, it is better understood as a communication mediator.

Touch initiates a biochemical conversation.
That conversation influences blood flow, nerve behavior, and ultimately movement.

The semitendinosus
Why is it always the middle one??

As always the horses body is like a story book, or even sometimes an archeology site for looking at the superficial often tells us of the history of the horse as we dig deeper into the why.

Out of all the muscles the semitendinosus is probably the most common one we will see, the most massaged muscle out of them all yet a hypertrophied muscle needs others to take up the slack in order to begin not to be hench, but where would we begin, why does it feel it has to overwork, and can we really do anything about it years after the fact.???

So what is the semitendinosus??

It is part of a trio in the group of muscles we may recognise more easily as the hamstrings, these muscles like with the human are linked to the knee.
Yet the connections from the pelvis to the hock is like a scaffold incorporating many structures as it heads its way down
We often only look at origin and insertion and forget all the bits in between, humans like to think linear its easier to understand where we pull in one place and there is a clear definate line to have an affect in another, but the body has a complex connective relationship with other structures so while others may look from point A. To B. I always ask the question what about all the other structures linked into the path the muscle takes.

Origin
(Two heads) Last sacral vertebrae, Transverse process of the 1st and 2nd coccygeal vertebrae (Tail bones). Sacrotuberous ligament, caudal fascia, Ventral side of the Tuber ischium (bottom of the pelvis).

Insertion
Cranial border of the tibia via aponeurosis (a sheet of connective tissue). Crural fascia (part of the fascial sheet system ) and the tendon merges with others structures to form the Calcaneus tendon which hooks over the Calcaneous (bony part of the back of the hock which you can feel).

Function
Extends the hip and hock when the limb is weightbaring, also flexes the stifle when non weightbaring, draws the limb caudally, propulsion for forward movement.

So lets look at the origin, as you can see it connects to the tail and some pretty important pelvic comnections so how will it function if lets say a tail is off to one side, we all know tails mainly go off to the left if there is dysfunction and we then see that right semitendinosus larger, thats a little but more added to the story, but wait if one side is overworked then others will be underworked so neither is correct.

So check the pelvis, asymmetry here will create tight on one side and lax on the other, what do you do if you are a little high on one hip ?? You load your limbs unevenly, which means shoulder will load unevenly, ribcage will rotate more to one side and so on. Take a dorsal picture of your horse see how the view is from the tail to the head, is there any deviations??

How are the stifle and hocks?? Any changes going on there if the joints are limited in their range of motion then it isn’t only a joint issue all the connecting parts will also begin to limit their range of motion and when one area becomes restricted another will over compensate.

Why is it usually bulging?? Often we see this a lot on horses that may have worked early in their life with excessive force on acceleration, so think of the racehorse coming out of the gate so often when we see it its years in the making a whole system built around it so change takes along time and sometimes change is not possible but management is.

Weak glutes, will overload the semitendinosus (i think we all know this when we begin running when not fit).

Not moving, if your horse is stabled alot then has bouts of excessive work.

Repetitive strain on structures like the hock
Posture, if you horse adopts a a more forward tilted pelvis then load will be put on to the hamstrings, muscles like to move not be in one static position of either lengthened or contracted.

If the stifles have a problem then often the hamstrings will there are many muscles connected to the stifle, quality of a joint relies on quality of the muscle and vice versa and we must not forget all the connective tissue that supports this area
Weak core means Weak muscles, a hamstring group that isnt working together means the propulsion may be lacking

And remember the aesthetics of the horse is a smooth streamlined body they are not bodybuilders but like us sometimes the discipline they do will mean they will build up muscle in certain areas.

What does it mean for my horse??
Dont panic many horses do just fine, its probably the most common thing we see, horses can and do ok and often its built up over time, if you see a dramatic sudden change then often it can indicate injury but many things that horses have is their new normal and we have to help work with the body before us to make things better rather than terrifying the owner that all is lost.

So what can you do, ??
First take a picture, look for weak areas where you can support. Often core, quads and glutes.
Try a range of motion with the hind limbs, see where you feel the resistance but never push past that point, work slowly over time asking for a little bit more when you feel them relax, often these horses like it when there limb is held up but get icky on the way down, learn to feel the sticky bit and just lift a little higher, don’t let the foot slam down

Look when you lift a forelimb if the horse doesn’t want to load onto the hind and rocks from heel to toe then it may indicate a little discomfort
Look for the ischium rock I have it somewhere on my videos again go slow we are not pushing on the Tuber ischium to get the pectorals moving we are going slow feeling for any resistance, as always when we feel resistance we wait until. It passes and then ask again with smaller moves
If the trio isn’t working together then we don’t only focus on the one we see we need to focus on the whole horse not one area.

Can your horse bring its hindlimb across the midline.?? I often see hindlimbs doing moves which i call helicopter legs as they look like helicopter propellers swinging out 🙂 for good a good functioning hind end your horse has to be a able to do the hokey cokey with its limbs😊

Massaging can help it often wont change years of dysfunction but it can offer some relief from the daily dysfunction, don’t go in all Bruce Lee, sore muscles need a soft touch not a hammering (ouch!!!).

And dont hyper focus in what you can see imagine the things you cant, the connections, the knock on effect for there you will be looking at the whole horse not an isolated muscle
