What Is a Subluxation — And How Does Fascia Play a Role?

When people hear the word subluxation, they often imagine a bone that has somehow slipped dramatically out of position. In reality, the term can mean different things depending on the context in which it is used.

In modern medicine, a subluxation generally refers to a partial loss of normal joint alignment or contact. It is different from a complete dislocation, where the joint surfaces are completely separated.

But there is another way of looking at joint dysfunction — one that is particularly relevant to myotherapy, soft-tissue therapy and movement rehabilitation: the relationship between the joint, muscles and fascia surrounding it.

Rather than thinking of a joint as an isolated mechanical structure, it can be more useful to see it as part of an interconnected system of muscles, tendons, ligaments, fascia and nervous tissue.

What Actually Holds a Joint in Position?

Joints aren't held together by bones alone.

Their stability depends on a combination of:

• The shape of the joint surfaces

• Ligaments and joint capsules

• Tendons and muscles

• Fascial structures

• Neuromuscular control

• Proprioception

• The way we load and move the joint

This means that changes in the tissues surrounding a joint can influence how that joint moves and how forces are distributed through it.

This is where fascia becomes particularly interesting.

What Is Fascia?

Fascia is a continuous network of connective tissue that surrounds, separates and connects muscles, organs, nerves, blood vessels and other structures throughout the body.

Rather than being a collection of isolated sheets, fascia forms a three-dimensional network extending throughout the body.

When you move, forces aren't necessarily transmitted through one muscle or one joint in isolation. They can be distributed through multiple layers of connective tissue and across neighbouring structures.

This is one reason why a restriction in one area can sometimes influence movement somewhere else.

For example, altered tension around the hip may influence pelvic mechanics, which can subsequently affect the lumbar spine. Similarly, restrictions around the shoulder girdle can alter how the scapula moves and ultimately influence shoulder mechanics.

Can Fascia Actually Cause a Subluxation?

This is where some nuance is important.

Fascia doesn't normally "pull a bone out of place" like a rope pulling a lever. The relationship is much more complex.

However, changes in the tension, stiffness and movement of the muscles and connective tissues surrounding a joint can influence joint position, movement and load distribution.

Imagine a joint being surrounded by several muscular and fascial structures, each exerting forces in slightly different directions.

If one group becomes excessively shortened, stiff or overactive while its opposing structures become inhibited or lengthened, the balance of forces around the joint can change.

The result may be altered joint tracking or movement.

In some circumstances, particularly when combined with ligamentous laxity, trauma, repetitive loading or structural abnormalities, this can contribute to joint instability or subluxation.

The Fascial System and Joint Position

One of the most important concepts in understanding fascia is force transmission.

Muscles don't operate independently. Their connective-tissue attachments blend into tendons, aponeuroses and fascial planes, creating pathways through which mechanical forces can be transmitted.

Consider the pelvis.

The position of the pelvis is influenced by the coordinated activity of the:

• Gluteals

• Hip flexors

• Hamstrings

• Adductors

• Abdominal muscles

• Lumbar musculature

• Thoracolumbar fascia

• Sacroiliac ligaments and surrounding connective tissues

If certain tissues become chronically tense while others fail to contribute appropriately, the pelvis may adopt a different resting position or movement strategy.

The bones themselves haven't necessarily "moved out of place." Instead, the system controlling their position and movement has changed.

That distinction is important.

Tension, Restriction and Compensation

Fascial restrictions can develop for many reasons.

These can include:

Injury:Following an injury, the body may increase muscular tone and protective tension around an area.

Repetitive movement:Repeatedly performing the same movement can place consistent demands on particular tissues.

Training:Strength training, sport and physically demanding occupations can create adaptations in muscle and connective tissue.

Sedentary behaviour:Long periods in the same position can influence tissue tolerance and movement strategies.

Stress and the nervous system:Muscle tone is also influenced by the nervous system. Stress, fatigue and perceived threat can increase protective muscular activity.

Over time, these factors can contribute to changes in how a joint is controlled.

The body then often develops compensations.

One joint may become less mobile, while another becomes more mobile to compensate. One muscle may become overactive while another contributes less. Movement can gradually become less efficient.

This is often where people begin describing a joint as feeling "out," "stuck" or "misaligned."

The Nervous System Matters Too

Fascia isn't simply passive wrapping around muscles.

The connective tissues surrounding joints contain sensory receptors that contribute to proprioception — our ability to perceive the position and movement of our body.

When tissue sensitivity or muscle tone changes, the brain receives different information about what's happening around a joint.

This can influence motor control.

In other words, joint mechanics aren't determined solely by the physical tissues. They are also influenced by how the nervous system perceives and controls those tissues.

This is one reason why simply "putting a joint back into place" may not always address the underlying problem.

If the movement pattern, muscular control or tissue loading that contributed to the dysfunction remains unchanged, the same problem can potentially return.

Is It Really a "Misaligned" Joint?

This is an important question.

People commonly say things such as:

"My hip is out."

"My pelvis is twisted."

"My shoulder is sitting out of place."

Sometimes these descriptions reflect a genuine joint instability or subluxation.

But often they are describing altered movement, muscle tension, joint stiffness or a change in proprioception, rather than a bone being permanently displaced.

The body is dynamic.

Joint position changes constantly as we walk, breathe, exercise and perform everyday activities. There isn't necessarily one perfect position that every joint should occupy at all times.

What matters is whether the joint can move appropriately, tolerate load and remain stable for the demands placed upon it.

Where Myofascial Therapy Can Help

Myofascial and soft-tissue therapy can be useful when altered muscle tone, tissue sensitivity or restricted movement is contributing to dysfunctional movement patterns.

Treatment may aim to:

• Reduce excessive muscular tension

• Improve tissue mobility

• Restore comfortable range of motion

• Improve proprioceptive awareness

• Reduce protective muscle guarding

• Improve movement quality

• Allow more efficient loading of a joint

But manual therapy shouldn't be viewed as physically "putting bones back into place."

A more useful model is that treatment can change the mechanical and neurological environment surrounding a joint, giving the person an opportunity to move more effectively.

This is particularly valuable when combined with appropriate strengthening, mobility work and movement retraining.

Fascia Is Part of the System — Not the Whole Explanation

It's tempting to blame fascia for everything.

But joint dysfunction is rarely caused by one structure acting alone.

A more complete model considers the interaction between:

Bones + joints + muscles + fascia + ligaments + nervous system + movement + load.

A joint can become unstable because of trauma or ligament injury. It can become restricted because of capsular changes.

Muscular imbalance can influence its movement. Neurological factors can alter muscle tone and coordination. And repeated loading can gradually change how the entire system functions.

Fascia is an important part of this picture because it provides continuity and force transmission throughout the body.

But it is one component of a much larger system.

The Takeaway

A subluxation is generally understood as a partial loss of normal joint alignment or contact, although the term is used differently across healthcare disciplines.

Fascia doesn't simply pull bones out of alignment. Instead, changes in fascial and muscular tension can influence how forces are transmitted around the body, how joints move and how the nervous system controls those

movements.

Understanding this distinction allows us to move beyond the idea that every painful or "out of place" joint simply needs to be pushed back into position.

Sometimes the real solution isn't to force a joint into a different position.

It's to understand why the body adopted that position in the first place — and then restore the capacity to move, stabilise and load the joint effectively.

If you experience recurrent joint instability, suspected subluxation, significant pain or a joint that repeatedly "gives way," assessment by an appropriately qualified healthcare professional is recommended. Manual therapy should complement, rather than replace, appropriate clinical assessment and rehabilitation.
