🍁 With the leaves changing here in the Northeast, let’s talk about RED MAPLE POISONING! 🍁

What is red maple poisoning?

Red maple poisoning occurs when horses ingest wilted, dried, or fallen leaves from the red maple tree (Acer rubrum).

Red maple leaves contain compounds, including pyrogallol, that can cause oxidative damage to red blood cells. This can lead to methemoglobinemia and severe hemolytic anemia, which reduces the blood’s ability to carry oxygen throughout the body.

Clinical signs can develop within hours to several days after ingestion, depending on the amount consumed and the condition of the leaves.

🚨 Signs of red maple poisoning
🟤 Brown or dark-colored urine
⚪ Pale or yellow-tinged gums
🐴 Colic, depression, or lethargy
❤️ Increased heart rate
🫁 Increased respiratory rate or difficulty breathing
🌡️ Weakness or exercise intolerance
🐎 Occasional laminitis
Treatment & prognosis

Treatment for red maple toxicity can be intensive and expensive. Depending on the severity of the poisoning, treatment may include IV fluids, oxygen support, intensive monitoring, and blood transfusions.

The prognosis can be guarded, particularly in horses with severe anemia or significant red blood cell destruction. Early recognition and treatment are important.

🌳 Prevention is key!

The best way to protect your horse is to prevent access to red maple leaves, particularly wilted or fallen leaves. Regularly inspect pastures and remove fallen leaves and branches, and consider managing or removing hazardous trees around turnout areas.

If you suspect your horse has ingested red maple leaves or is showing any of these signs, contact your veterinarian immediately. Early veterinary intervention can make an important difference in the outcome.

🐴🍁 Keep your four-legged friends safe this fall!

How a Girth Can Affect the Way a Horse Moves

A girth occupies a relatively small area of the horse’s body, but the structures beneath and around it are part of a much larger mechanical system.

This is one reason girth fit matters for more than comfort.

The girth wraps around the lower thorax, crossing the sternum and pectoral region and applying pressure over the ribs and the soft tissues covering them. Depending on conformation, girth design and position, that pressure may be concentrated over particular areas rather than distributed evenly.

Underneath and around the girth are structures involved in breathing, supporting the trunk between the forelimbs, stabilizing the rib cage and coordinating movement of the shoulder and forelimb.

So if pressure or discomfort changes how the horse uses this region, the effects do not necessarily stay underneath the girth.

The Rib Cage Has to Move

The ribs are not rigid bars.

They move during breathing and also participate in the subtle deformation and movement of the thorax that occurs during locomotion. Between them lie the intercostal muscles, while the surrounding fascial tissues connect the rib cage with neighboring muscles of the trunk.

If girth pressure causes discomfort, the horse may guard the area, reduce movement through the thorax or change muscular recruitment around the ribs and sternum.

Even relatively small changes matter because the rib cage is also the structure being supported between the forelimbs.

The Thoracic Sling

Unlike humans, horses do not have a bony collarbone attaching the forelimbs directly to the trunk.

Instead, the trunk is suspended between the forelimbs largely by muscles and connective tissues collectively described as the thoracic sling.

One of the most important is serratus ventralis. Its thoracic portion attaches to the ribs and helps suspend and stabilize the trunk relative to the scapula.

The pectoral muscles also contribute to stabilization and control of the forelimbs and trunk.

These structures are closely associated with the region affected by the girth.

That means discomfort, compression or guarding around the ventral and lateral thorax can potentially influence the muscular system responsible for supporting and controlling the trunk between the shoulders.

The Scapula Has to Move Too

The scapula is not fixed rigidly against the rib cage. It moves relative to the thorax as the forelimb advances and retracts.

That movement depends upon coordinated activity between the muscles attaching the scapula and humerus to the trunk, as well as sufficient freedom within the surrounding tissues.

This is where the anatomy becomes particularly interesting.

Latissimus dorsi extends from the thoracolumbar region of the back toward the humerus. It therefore creates a direct muscular and fascial connection between the back, trunk and upper forelimb.

Deep in the shoulder region is teres major, which runs from the caudal scapular region to the humerus. It helps flex the shoulder and draw the forelimb backward, functioning closely with latissimus dorsi during movement.

Teres major and latissimus dorsi are also closely associated near their humeral attachments, where their tendinous and fascial tissues have an intimate anatomical relationship.

So teres major does not need to sit directly underneath the girth to be relevant.

It is part of a connected mechanical system extending from the scapula and humerus through latissimus dorsi into the trunk, back and thoracolumbar fascia, while the thorax beneath is being supported and stabilized by the serratus ventralis and other thoracic sling structures.

The Effects Don’t Stop at the Girth

The horse still has to balance and move even when one area becomes uncomfortable or mechanically restricted.

If the horse guards the girth region, alters rib-cage movement or changes recruitment of the pectoral and thoracic sling musculature, the mechanical environment in which the scapula and forelimb operate also changes.

Muscles such as latissimus dorsi and teres major still have to coordinate movement of the humerus and shoulder. Serratus ventralis still has to help support the trunk. The long back muscles and thoracolumbar fascia still have to transmit and manage forces through the trunk.

The horse may therefore find another way to accomplish the movement.

The neck may change how it contributes to balance. The back and abdominal musculature may change their recruitment. Scapular and forelimb mechanics may change. Stride characteristics and loading can change, and compensation can continue farther through the body.

This is how discomfort originating in a relatively small region beneath the girth can become a much larger movement issue.

Girth pressure or discomfort
→ guarding and altered muscle recruitment
→ altered rib, sternal and thoracic sling function
→ altered support and control of the thorax
→ changes in the mechanical environment of the scapula and shoulder
→ altered function of muscles linking the forelimb, trunk and back, including latissimus dorsi and teres major
→ changes in balance and forelimb movement
→ compensation elsewhere in the body.

A girth is not simply a strap around the horse.

It sits over a region where breathing mechanics, rib movement, thoracic support, shoulder function, fascia and whole-body locomotion intersect.

That is why girth fit, placement, pressure distribution—and the horse’s response to them are an important part of the way the whole horse moves.

Fascia and the Tension Cycle: How the Body Adapts—and Gets Stuck

What begins as a normal, protective response in the body can sometimes become a pattern that’s hard to undo.

A small injury, strain, or even repeated stress can create tension in the tissues. Over time, the body adapts to that tension—and if it isn’t resolved, the system can become organized around it.

This is how helpful becomes limiting.

Fascia, Fibroblasts, and Tension in the Horse

Fascia can tighten and compress surrounding structures—nerves, blood vessels, lymphatics, and the extracellular matrix (ECM)—reducing their ability to move, glide, and communicate effectively.

A key driver of this process is the behavior of fibroblasts and myofibroblasts.

What Fibroblasts and Myofibroblasts Do

Fibroblasts

Fibroblasts are the primary cells responsible for maintaining and remodeling fascia.
• Produce collagen and ground substance
• Respond to mechanical load and movement
• Help maintain tissue elasticity and hydration

In a healthy system, fibroblasts support adaptability and resilience.

Myofibroblasts

Under certain conditions—such as injury, inflammation, or sustained tension—fibroblasts can transform into myofibroblasts.
• Have contractile properties (similar to smooth muscle)
• Generate and maintain tension within the tissue
• Continue responding to mechanical stress when tension persists

This is beneficial during short-term healing, but becomes problematic when it continues long after it’s needed.

How This Creates Restriction

When myofibroblast activity remains elevated:
• Fascia becomes denser and less elastic
• Tissue layers lose their ability to glide freely
• Nerves may become mechanically restricted
• Blood and lymph flow can be compromised
• The ECM becomes less fluid and more resistant

This creates a system where:

Tension reinforces tension

Effects in Key Areas of the Horse

Thoracolumbar Fascia & Back Muscles

This region is critical for force transmission between the front and hind end.

When fascial tension increases:
• The back becomes rigid or guarded
• Reduced ability to lift and swing through the topline
• Decreased shock absorption
• Altered coordination between limbs

You may see:
• Hollowing
• Shortened stride
• Resistance to bending or collection

Latissimus Dorsi

The latissimus dorsi connects the forelimb to the trunk and helps coordinate movement and stability.

With increased fascial tension:
• Reduced ability for the forelimb to reach forward freely
• Increased load through the shoulder
• Reduced ability to control ribcage movement
• Compensation patterns through the back

Pectoral Muscles

The pectorals support the trunk between the forelimbs.

When restricted:
• Decreased ability for the thorax to lift and stabilize
• Reduced shock absorption
• Increased strain through the forelimbs and shoulders

Where Massage Therapy Fits In

Massage therapy helps interrupt this cycle by changing the environment the tissue and nervous system are responding to.
• Reduces excessive mechanical tension within the fascia
• Improves glide between tissue layers
• Supports circulation and lymphatic flow
• Provides clearer, more organized sensory input to the nervous system

This can help shift fibroblast and myofibroblast activity away from persistent contraction and toward a more adaptable state.

Rather than forcing change, massage:

Creates the conditions for the body to let go of unnecessary tension

The Bigger Picture

When fascia is under chronic tension:
• Movement becomes less efficient
• Load is distributed unevenly
• The nervous system receives less clear input
• Compensation patterns develop

Over time, this affects performance, comfort, and durability.

Why This Matters

Myofibroblasts are not the problem—they are part of a protective and adaptive response.

The issue arises when:
• Tension is never resolved
• The system does not return to a more relaxed, adaptable state

Final Thought

Movement reflects how the body coordinates itself under load.

Fascia doesn’t just tighten—it adapts.
And when that adaptation becomes chronic, it can restrict movement, communication, and function throughout the entire system.

Fascia!!

12 Interesting Things About Thoracolumbar Fascia

1. Thoracolumbar fascia connects directly with no fewer than 7 myofascial lines and coordinates directly with at least two more. More on these coming soon.

2. It consists of multiple layers of fibrous fascia that vary in thickness and density.

3. The thoracolumbar fascia inserts into the sacrum at the base of the spine and the iliac crest of the pelvis, and it merges with 12 different muscles on each side of the spine.

4. It originates from the nuchal ligament and has additional attachments to the spinous processes of the thoracic and lumbar vertebrae.

5. It acts as a central structure that distributes mechanical forces, supporting the integrity of the back.

6. Muscles that attach to and are embedded within the thoracolumbar fascia can increase its tension.

7. Tension within the fascia can be increased by several involuntary factors, such as the contraction of myofibroblasts in response to mechanical stress or during the healing process. Increased viscosity of the interstitial fluid, adhesions, and tissue thickening can also contribute to heightened fascial tension.

8. The thoracolumbar fascia works with the lateral and ventral abdominal muscles, as well as other structures within the thorax, to create a corset-like effect that enhances intra-abdominal pressure. This coordination helps stabilize the thorax and reduce the load on the vertebrae.

9. The equine thoracolumbar fascia is richly innervated with sensory receptors that respond to mechanical pressure or distortion. These receptors contribute to the horse’s ability to sense and coordinate body movement, posture, and balance.

10. The thoracolumbar fascia distributes mechanical stress across the thoracolumbar spine and pelvis, minimizing localized stress and reducing the risk of injury.

11. The weight of the rider, combined with the fit and placement of the saddle, directly interacts with the thoracolumbar fascia.

12. The thoracolumbar fascia and its integrated muscles can only perform their functions correctly if the fascia surrounding them is mobile enough to allow full sensory input, coordination, and function.

7 Reasons Chiropractic Alone Is Often Not Enough for Horses

Chiropractic work can absolutely help horses.

Improving joint mobility, reducing restriction, and influencing nervous system input can create meaningful changes in comfort and movement quality.

But many horses continue to struggle even after repeated adjustments.

Why?

Because movement problems are rarely caused by joints alone.

The body functions as an integrated system involving fascia, muscle tone, coordination, balance, proprioception, behavior, compensation patterns, and nervous system regulation.

Adjusting the joints without addressing the rest of the system is often incomplete.

Here’s why.

1. Fascia Connects the Entire Body

Fascia is a continuous connective tissue network that surrounds and integrates muscles, joints, nerves, organs, and movement chains.

Restriction in one region can influence movement somewhere else entirely.

A horse may receive a successful adjustment, but if surrounding fascial tension patterns remain unchanged, the body may continue pulling the horse back into the same compensation strategy.

The joint changed.
The system did not.

2. Hypertonic Muscle Can Pull the Body Back Into Compensation

Many horses develop chronic muscular guarding and hypertonicity.

Importantly, hypertonic does not mean strong.

Often these muscles are:

* protective
* compensating
* overworking
* poorly coordinated
* or responding to instability elsewhere

If excessive muscular tension is not addressed, the horse may temporarily improve after chiropractic work but gradually return to the same posture and movement patterns.

3. The Nervous System Controls Movement

Movement is not controlled by bones alone.

The nervous system constantly regulates:

* muscle tone
* coordination
* posture
* movement variability
* balance
* protective responses

If the nervous system still perceives instability, discomfort, overload, or lack of safety, the body may continue using the same movement strategies regardless of joint position.

This is one reason some horses seem to “need constant adjustments.”

4. Restriction Is Often a Whole-Body Pattern

A horse protecting one area rarely compensates in only one place.

For example:

* thoracic sling dysfunction may affect the neck, ribs, lumbar region, and hindquarters
* pelvic restriction may alter trunk stabilization and forelimb loading
* poll tension may connect into broader fascial and postural chains

Massage and myofascial approaches can help address broader tension patterns that may not be fully resolved through localized joint work alone.

5. Proprioception and Coordination Matter

Many horses do not simply lack mobility.

They lack efficient control of mobility.

A horse may have enough range of motion physically but still move poorly because of:

* weak proprioception
* poor coordination
* instability
* reduced body awareness
* compensation patterns

Improving movement quality often requires helping the horse reorganize movement patterns, not simply increasing motion in individual joints.

6. Stress and Emotional State Affect the Body

Horses carry stress physically.

Emotional arousal, anxiety, hypervigilance, environmental pressure, pain anticipation, and chronic stress can all increase muscular and fascial tension.

A horse in a chronically protective nervous system state may struggle to maintain physical changes because the body continues prioritizing protection over fluid movement.

Massage and fascial work may help influence parasympathetic regulation and reduce excessive guarding behaviors.

7. Lasting Change Usually Requires Systemic Change

The horses that improve the most long term are usually not the ones receiving only one type of therapy.

They are often the horses whose overall system improves through:

* movement quality
* strength and coordination
* recovery
* balance
* conditioning
* appropriate loading
* body awareness
* stress reduction
* and improved movement experiences

Chiropractic can be an important piece of that puzzle.

But rarely is it the entire puzzle.

Final Thought

This is not about chiropractic versus massage or fascia therapy.

It is about recognizing that horses are complex adaptive systems.

No single modality addresses every part of movement, compensation, posture, coordination, and nervous system regulation.

The more completely we understand the system,
the more effectively we can help the horse.

I love poles!

A recent study from the University of Tennessee provided strong support for something trainers, movement specialists, and bodyworkers have observed for years:

Ground poles significantly increase activation of important postural and core muscles in horses.

What the Study Found

Walking over ground poles increased activity in:

• Longissimus dorsi — a major topline and spinal support muscle
• Abdominal muscles — critical for core stability and support of the spine

Even at the walk, poles require the horse to:

• Lift the limbs higher
• Stabilize the trunk more actively
• Organize posture and balance with greater precision
• Continuously adjust limb placement and timing

At the trot, researchers also found increased activation of the abdominal muscles.

Trotting over poles requires greater dynamic stabilization, and the increased limb elevation demands more coordinated control of the trunk, pelvis, and spine.

What This Means

These findings support the long-standing use of cavaletti and ground poles as a low-impact way to:

• Strengthen the topline
• Improve abdominal engagement
• Support spinal stability
• Enhance proprioception and coordination
• Encourage improved posture and self-carriage
• Develop better movement organization through the whole body

One of the most important aspects of pole work is that it influences both sides of the postural system:

• The dorsal chain — including the longissimus muscles along the back
• The ventral chain — including the abdominal support system

This balance is essential for efficient movement, force transfer, and development of a healthy, functional topline.

But pole work is not only muscular.

It is neurological.

Each pole creates a movement problem the horse must solve in real time.

The horse has to:

• Judge distance
• Adjust stride length
• Control timing
• Stabilize the trunk
• Organize the limbs in space
• Adapt moment-to-moment to changing demands

That process requires attention, coordination, body awareness, and ongoing nervous system regulation.

In many horses, poles appear to improve focus not simply because the horse is “behaving,” but because the nervous system is becoming more engaged and organized around the task.

Pole work may also influence neurological tone — the background level of muscular and nervous system readiness that affects posture, movement quality, stiffness, and coordination.

For some horses, this can help reduce excessive bracing and improve adaptability through the body.
For others, it can help improve postural engagement and overall organization.

Why It Matters

Regular pole work can benefit many types of horses:

• Young horses developing coordination and posture
• Performance horses improving strength, agility, movement quality, and limb awareness
• Horses rebuilding core control and stability after periods of weakness or reduced work
• Older horses maintaining mobility, coordination, and movement confidence

Importantly, many of these benefits occur even at the walk, making poles accessible to horses across a wide range of ages, disciplines, and fitness levels.

Rather than simply “making horses pick up their feet,” poles appear to challenge the nervous system, postural system, sensory system, and muscular system together — encouraging the horse to organize movement with greater control, awareness, and adaptability.
