Cribbers and Bodywork: Why Are Some So Good at Receiving It?
When we talk about cribbing, we usually talk about why horses do it.
Stress. Ulcers and gastrointestinal health. Management. Stereotypic behavior. Endorphins and the way cribbing helps some horses regulate how they feel.
But bodyworkers often notice something else.
Some cribbers are remarkably good at receiving bodywork.
They settle into it. They become deeply engaged with touch. They seem highly aware of changes occurring in their bodies.
And at the same time, they have spent months or years repeatedly performing a powerful physical action involving the teeth, jaw, throat, neck and often the entire front of the body.
These two things are worth looking at together.
What has cribbing taught the horse about changing his own internal state?
And what has performing that same physical action thousands upon thousands of times done to his body?
Cribbing Is a Physical Action
Watch a cribber closely. This isn’t a small movement.
The horse anchors his incisors on a fixed surface, recruits the jaw and throat, positions and contracts the neck and often braces or pulls through the front of his body.
Then he repeats it.
Again and again.
If a horse performed almost any other movement this frequently, we would consider that repetition when assessing his muscles, posture and movement.
Cribbing deserves the same consideration.
The jaw and muscles of mastication are obvious participants. The horse grips the surface with his incisors while structures associated with the jaw, tongue and throat participate in the action.
Then look at the neck.
The characteristic cribbing movement repeatedly recruits the cervical musculature. The poll and upper cervical region, ventral neck and muscles connecting the head, neck, sternum and shoulder all deserve attention.
The hyoid and laryngeal region are also anatomically involved in the cribbing action. These are sensitive structures and not areas for aggressive manipulation, but their involvement reminds us that cribbing is far more than a horse simply grabbing something with his teeth.
And the movement doesn’t stop at the base of the neck.
Follow the Movement Into the Rest of the Body
A horse pulling or bracing against a cribbing surface has to stabilize his body.
Watch the shoulders and forelimbs. Watch the base of the neck and thoracic sling. Watch what happens through the trunk when the horse pulls against the surface.
Repeated head and neck positioning also becomes part of the horse’s habitual muscular use. Over thousands of repetitions, that matters to the rest of the topline.
This doesn’t mean every cribber develops an identical collection of tight muscles.
The individual horse’s cribbing technique is more useful than simply knowing he is a cribber.
Watch him.
How high is his preferred cribbing surface?
How does he position his head and poll?
How strongly does he contract or arch his neck?
Does he pull backward?
Does he brace through his forelimbs and shoulders?
Does his weight shift backward?
Does he repeatedly use exactly the same position?
You are watching a movement pattern that this horse has practiced an extraordinary number of times.
That is valuable information when you put your hands on him.
So Why Are Some Cribbers So Good at Bodywork?
This is where the neurological side of cribbing becomes especially interesting.
Cribbing has been associated with stress physiology, gastrointestinal health, dopamine and reward systems and the endogenous opioid system—the body’s own endorphins and related opioid peptides.
This is where the familiar idea that cribbing releases endorphins comes from.
That explanation became oversimplified into the idea that horses crib because they get an endorphin “high.” The physiology is more complex than that.
What is important is that an established stereotypy can function as a form of self-regulation.
The horse isn’t necessarily performing a meaningless repetitive action. Cribbing changes his sensory experience and physiological state, and the behavior becomes strongly established because it serves a function for him.
This also helps explain why simply preventing an established cribber from cribbing doesn’t solve the problem. The motivation and physiological processes behind the behavior are still there, and preventing access to the behavior can increase stress.
Now think about what happens during good bodywork.
Bodywork provides another powerful source of sensory information.
Touch changes sensory input from the skin, fascia, muscles and joints. Muscular guarding changes. Autonomic activity changes. The nervous system receives a continuous stream of information about what is happening throughout the body. Endogenous pain-regulating systems are involved as the horse settles and the experience becomes comfortable and predictable.
Horses also learn to receive bodywork.
A horse that initially watches every movement of the therapist often becomes increasingly skilled at participating in the experience. He recognizes what touch means. He begins to anticipate it. He learns that he can soften rather than protect himself against it.
That makes the cribber particularly interesting.
A horse that has spent years using a highly repetitive sensory-motor behavior to alter his internal state already has extensive experience with the relationship between physical action and how his body feels.
Bodywork offers a very different route to changing that internal state.
This gives us a useful way to understand why some cribbers appear so exceptionally receptive to it without reducing the explanation to, “They like endorphins.”
The Cribber Gives Us Two Important Pieces of Information
For the bodyworker, cribbing has both a neurological and a mechanical side.
It is a deeply established behavior associated with regulation, reward, sensory processing and internal state.
It is also a highly repetitive physical action that loads the jaw, throat, neck and structures used to brace and stabilize the body.
Those aren’t separate stories.
The same horse is doing both.
Years of cribbing can influence the tissues and movement patterns we encounter under our hands, while the regulatory function of cribbing helps us understand something about the horse receiving the work.
Bodywork isn’t a treatment for cribbing. Releasing the jaw or neck isn’t going to remove the neurological, gastrointestinal, environmental or learned factors behind an established stereotypy.
But knowing that a horse cribs should change what we look at.
Assess the muscles of mastication and jaw region.
Pay attention to the poll and cervical musculature.
Don’t overlook the ventral neck.
Follow the pattern into the base of the neck, shoulders, thoracic sling and topline.
And, most importantly, watch the horse crib.
The movement itself tells you what he repeatedly asks his body to do.
Then watch him during bodywork.
A cribber who becomes deeply absorbed in the work is telling you something too.
Cribbing isn’t only a behavior happening in the horse’s brain, and it isn’t only a repetitive movement happening in his muscles.
It involves both.
Understanding that gives us a much more useful picture of the horse under our hands.
