Quick answer. Trigger points are knots that lock a muscle in a shortened state. Adhesions are bands of tissue that glue muscle and fascia layers together, preventing them from sliding. Both start as the body’s short-term protection against overload. In a body stuck in forward-only motion, they never release. Iler Method® work uses sustained, oil-free precision pressure to release them and restore the tissue’s ability to glide.

What is a trigger point?
A trigger point is a hyper-irritable spot within a taut band of muscle fibers. It is a localized area where blood flow is restricted, causing metabolic waste to accumulate and keeping the muscle locked in a constant state of contraction.
You can usually feel it as a knot that is harder than the surrounding tissue. Pressing on it produces a familiar, productive good hurt. Trigger points sit in the belly of the muscle, the thick central part. Their primary mechanical cost is strength. Because a muscle stuck in a shortened state cannot fully lengthen or contract, it fatigues rapidly and cannot generate proper muscular force.
What is an adhesion?
An adhesion is structurally distinct from a trigger point. It acts like biological glue between layers of tissue. Your fascia, the connective tissue that wraps and separates your muscles, is designed to allow those layers to slide past one another smoothly. When fascia loses that slide, it thickens and binds together tissue layers that should move independently.
An adhesion feels less like a distinct knot and more like a dense internal restriction, or a mechanical catch during movement. Adhesions tend to develop near bony prominences and where muscles attach to bone. Their primary mechanical cost is range of motion. They act as physical obstructions that create stiffness when you move.
Why do trigger points and adhesions form?
Trigger points and adhesions are not random tissue failures. They are the body’s protective first aid against mechanical overload.
The human body has a built-in rightward asymmetric structural weight distribution. Two long muscle chains running up the back manage this imbalance with every step. Most of the mechanical load lands during the demanding side of the gait cycle, the path of effort, on the same specific tracking muscles in the neck, back, shoulders, and hips. In a body moving through varied directions, the tension built up during effort clears during rest, and a temporary trigger point would release.
Modern life, however, keeps the body locked in forward-only motion. Sitting, driving, walking, and running all occur while facing forward, with almost no lateral or rotational variation. This linear life keeps the demanding muscle chains constantly activated without a signal to stand down. To prevent a more severe mechanical failure, like a muscle tear, the body applies structural patches. Trigger points and adhesions form to physically limit range of motion and protect the area.
In the long term, these patches become permanent fixtures because the nervous system loses the ability to turn these muscles off. They stop acting as protection and become the primary source of chronic stiffness and pain. The physical record they leave behind at predictable locations along these muscle chains forms the body’s pain map.
Why you cannot stretch or train them away
You cannot stretch away a trigger point, and you cannot exercise away an adhesion. Attempting to stretch a muscle that is already locked short simply pulls on the healthier fibers around it without reaching the hyper-contracted knot. Adding load to an adhesion does not dissolve the biological glue binding the tissue layers together.
The tissue requires direct, manual release. Until that restriction is physically cleared, the muscle remains locked in a dysfunctional pattern.
How Iler Method releases them
The primary objective of the work is to restore glide. That is the smooth, independent sliding of muscle and fascia layers that allows the body to move without dragging against its own restrictions.
Iler Method sessions use precision pressure on oil-free, clothed skin. Working without oil provides the friction needed to anchor into the tissue rather than sliding over the surface of a restriction. The therapist applies steady, shearing force through a specific contact point, chosen for the depth and surface area of the muscle being worked.
- Fingers and thumbs. For fine, highly specific work on trigger points in the belly of a muscle.
- Knuckles or open palm. For adhesions across a broader surface, where tissue layers have bound together.
- Forearm or elbow. For adhesions in larger, denser muscle groups that need sustained, broad pressure.
This sustained pressure is applied and held firmly. The tissue releases not through brute force, but because the nervous system stands down under persistent, tolerable pressure. As the brain sends the signal to relax, the therapist feels the tissue soften and glide return.
The hands-on sequence is systematically structured. It begins at the primary site of pain to calm the body’s guarding response, then follows the overworked chain to resolve the underlying pattern, and incorporates movement to prevent the tissue from reloading immediately.
Why no oil and no music
The room is optimized for clinical focus. There is no oil because precision placement is impossible on a slick surface. There is no background music because active communication is a core element of the method. Your real-time verbal feedback about what you feel and where you feel it is how the therapist reads your pain map and calibrates pressure. Every choice in the room is designed to support precise tissue release rather than passive relaxation.
Frequently asked questions
What is the difference between a trigger point and an adhesion?
A trigger point is a hyper-contracted knot in the belly of a muscle that impairs strength. An adhesion is the binding of tissue layers near bony attachments that physically restricts range of motion.
What causes trigger points and adhesions?
They develop as a protective response to mechanical overload. Linear, forward-only daily habits keep the body’s management muscle chains constantly active, preventing these protective patches from naturally releasing.
Can sports massage help with chronic pain?
Yes, when that pain is driven by accumulated trigger points and adhesions. Physically releasing these restrictions and restoring tissue glide addresses the muscular source driving the discomfort.
What should I expect during an Iler Method session?
Sustained precision pressure applied through clothing, without oil or background music. The session relies on active communication to map and release the muscle chains driving your pattern. Your first visit begins with a Discovery Session combining a movement assessment and initial hands-on work. See our piece on the Discovery Session for what that includes.
How many sessions will I need?
Recommendations are set during the Discovery Session based on your history and how set the pattern is. Most clients follow either a six-session plan for defined, recent patterns, or a twelve-session plan for chronic, entrenched tension that requires more time to unwind.
Knots and stiffness that will not let go?
If trigger points and adhesions are limiting your range of motion and joint function despite stretching and training, the underlying pattern needs to be physically cleared.
