Beyond Muscle Knots: What Trigger Points Can Teach Us About Your Horse's Movement

If you're struggling to get to the bottom of your horse's performance issues, trigger points may be telling you a much bigger story than you realize.

My understanding of trigger points has changed over the years, not because I stopped thinking in patterns, but because I gained another way of explaining them. As I studied trigger points alongside biomechanics, fascia, and movement science, I began seeing the same message repeated through different disciplines.

Like most practitioners, I learned where trigger points were, how to find them, and how to treat them. If a horse came in with pain in a particular area, I expected to find trigger points in the muscles surrounding that region. It was logical, and honestly, it worked pretty well.

But after years of examining horses, something kept happening that I couldn't explain.

Horses would come to me with completely different problems. Different histories. Different veterinary diagnoses. Different reasons for the appointment.

Yet when I put my hands on them, I kept finding trigger points in many of the same muscles.

At first, I brushed it off. Maybe it was coincidence.

But after seeing it over... and over... and over again... it stopped feeling like coincidence.

It made me wonder if I was asking the wrong question.

Instead of asking, "Where are the trigger points?" I started asking, "Why is this muscle developing a trigger point in the first place?"

That simple shift completely changed the way I evaluate horses.

The Pattern I Couldn't Ignore

Most people think of a trigger point as a muscle knot. While that's not entirely wrong, it doesn't tell the whole story.

A trigger point is a small area within a muscle where a group of muscle fibers remains contracted instead of relaxing normally. As blood flow decreases, oxygen and nutrients become less available, waste products accumulate, and the nervous system begins responding to those changes. A trigger point isn't simply a muscle problem. It's a muscle and nervous system problem.

That distinction matters because horses don't move one muscle at a time.

Every stride requires hundreds of muscles working together. When one muscle isn't functioning normally, other muscles immediately begin adapting. Some work harder. Others change their timing. Some begin carrying loads they were never designed to handle.

The body doesn't stop moving because one muscle isn't doing its job.

It simply finds another way.

That's why I no longer think of trigger points as isolated findings. More often than not, they're evidence that the body has already adapted to something else.

The real question is...what?

Not Every Trigger Point Hurts

One of the biggest misconceptions about trigger points is that they're always painful.

They aren't.

Some are active trigger points, which are painful and often obvious. A horse may shorten its stride, resist bending, pin its ears during grooming, or react when the muscle is palpated.

Others are latent trigger points.

These may not cause obvious pain at all, but they can still affect how a muscle contracts, relaxes, and coordinates with the muscles around it. The horse may appear perfectly sound while quietly developing inefficient movement patterns.

That's one of the biggest lessons trigger points have taught me over the years.

Movement problems usually begin long before pain problems.

The body doesn't suddenly wake up one morning with chronic dysfunction. It adapts, compensates, and finds another way to accomplish the task.

Horses are remarkably good at doing exactly that.

By the time an owner notices soreness, resistance, or declining performance, those compensation patterns may have been developing for months, or even years.

Asking a Better Question

If you had asked me twenty years ago why trigger points developed, I probably would have given you a fairly simple answer.

Overuse. Poor saddle fit. An old injury. Poor hoof balance.

Those things certainly matter. Today, though, I think about the question differently.

Instead of asking, "What caused the trigger point?" I ask, "What problem was this muscle trying to solve?"

That may sound like an unusual question, but muscles are incredibly adaptable.

If one part of the body isn't contributing the way it should, another part almost always steps in. The body's goal isn't perfect movement. Its goal is to keep the horse functioning.

A horse still needs to graze, move, and perform, so the nervous system will find another strategy, even if that strategy isn't ideal.

That's why I no longer think a trigger point is the beginning of the story.

More often, it's evidence that the body has been adapting for a long time.

Once I started looking at trigger points this way, another pattern became impossible to ignore.

The muscles that consistently developed trigger points weren't random. They often belonged to two different groups with two very different jobs.

Understanding the difference between those muscle groups completely changed the way I think about movement, compensation, and rehabilitation.

And it helps explain why trigger points often return unless the underlying pattern is addressed.

The Missing Piece

As I kept asking why certain muscles developed trigger points, I realized I needed to look beyond the muscle itself.

The answer wasn't simply overuse. It wasn't simply poor saddle fit. It wasn't even the diagnosis.

The answer was often found in how the horse had adapted.

One concept that helped me make sense of those adaptations was understanding the difference between postural muscles and movement muscles.

Postural muscles, sometimes called tonic muscles, are the body's stabilizers. They work quietly in the background, maintaining posture, supporting joints, and helping the horse stay balanced. They aren't responsible for producing large, powerful movements. They're responsible for making efficient movement possible.

Movement muscles, or phasic muscles, have a different role. They're designed to create force, propulsion, and athletic movement. Once they've done their job, they're supposed to relax while the postural muscles continue providing stability.

When both systems are doing their jobs, movement is efficient.

The stabilizers stabilize.

The movers move.

But pain, injury, poor hoof balance, arthritis, saddle issues, or even subtle movement asymmetries can disrupt that balance.

Initially, that's exactly what the body should do. Compensation is an intelligent survival strategy that allows the horse to continue functioning despite a problem.

The trouble begins when compensation becomes the new normal.

As postural muscles work harder to stabilize an injured or unstable area, they can become chronically overactive. They never fully switch off. Over time, they often develop latent trigger points that quietly change the way the horse moves without creating obvious pain.

Eventually, the movement muscles begin helping with a job they were never designed to perform.

Instead of producing movement, they're now helping stabilize the body.

They fatigue more quickly. They become overloaded.

And many eventually develop painful trigger points of their own.

That's often when owners begin noticing changes. The horse resists bending. The stride shortens. One lead becomes more difficult. The neck braces. The back becomes sore. Performance declines.

By that point, however, the body may have been compensating for months, or even years.

That's why I've become less interested in simply finding trigger points and more interested in understanding why they developed.

The trigger point is often the end of the story. The adaptation is where the story begins.

Why Trigger Points Keep Coming Back

One of the biggest misconceptions I see is the idea that if you release a trigger point, you've solved the problem.

Sometimes you have. Often you haven't.

If the horse continues moving with the same compensation pattern, the nervous system will continue asking that muscle to do the same job.

Eventually, the trigger point returns.

That doesn't necessarily mean the treatment failed. It means the body is still trying to solve the same problem. That's why rehabilitation is rarely about one treatment or one practitioner. The veterinarian may diagnose the underlying condition. The farrier may improve how the horse loads the limb. The saddle fitter may remove a source of chronic pressure. The trainer may help develop healthier movement patterns.

My role is to improve muscle function and help restore more efficient movement.

When everyone addresses a different piece of the puzzle, the horse has the best opportunity to change the compensation pattern instead of simply managing it.

Looking Beyond Muscle Knots

One of the greatest lessons trigger points have taught me is that the painful muscle isn't always the muscle causing the problem.

Pain often tells us where the body has finally run out of options.

It doesn't necessarily tell us where the story began.

That's why I rarely interpret a trigger point by itself. I look at the horse's posture, movement, history, hoof balance, saddle fit, previous injuries, and the rest of the examination.

Only then does the trigger point become meaningful. It's no longer just a sore muscle. It's a clue. A clue to how the horse has adapted. A clue to what the nervous system has been trying to accomplish. A clue to where I should continue looking.

The longer I've worked with horses, the less I think of trigger points as muscle knots and the more I think of them as signposts. They point toward compensation, altered movement, and a body that's been working hard to solve a problem.

If we're willing to look beyond the trigger point itself, they can help us understand the much bigger story of how a horse moves.

And to me, that's the difference between treating a muscle and understanding a horse.
