What is a Movement System Impairment?

If you’ve ever wondered why your pain keeps coming back—even after rest, stretching, or physical therapy—you’re not alone. Many people are told they have tight muscles, weak muscles, or wear-and-tear changes on imaging. While those factors can play a role, they often miss a more important piece of the puzzle: how you move.

This is where the concept of a Movement System Impairment (MSI) comes in.

The Big Idea: Pain Is Often a Movement Problem

A Movement System Impairment is a consistent, repeatable movement pattern that places stress on tissues that are not designed to handle it. Over time, this repeated stress leads to pain, irritation, or injury.

In other words:

Pain is often not caused by what you did once — but by how you move every day.

MSI looks at the body as an integrated system rather than isolated muscles or joints. Instead of asking, “What structure hurts?” we ask:

• How does your body move during daily activities?

• Where are you moving too much?

• Where are you not moving enough?

• Which tissues are repeatedly overloaded?

Why Imaging Doesn’t Tell the Whole Story

Many people are surprised to learn that findings like disc bulges, arthritis, or labral tears are extremely common—even in people with no pain at all.

That’s because imaging shows structure, not movement.

Two people can have the same MRI findings:

• One has pain with everyday activities

• The other is completely symptom-free

The difference is often movement strategy, not damage.

How Movement System Impairments Develop

MSIs typically develop gradually and unintentionally through:

• Repetitive work or sport activities

• Prolonged sitting or standing

• Past injuries or surgeries

• Poor movement habits under load or fatigue

Over time, the body adopts compensations that feel normal but quietly overload specific joints or tissues.

Examples include:

• Excessive lumbar movement during bending

• Shoulder motion driven by the upper trap instead of the shoulder joint

• Hip stiffness leading to knee overload

These patterns become automatic—until pain forces your attention.

Common Examples of Movement System Impairments

Here are a few real-world examples:

Low Back Pain

Often linked to excessive movement at the lumbar spine and limited motion at the hips. Stretching the back may feel good temporarily, but it reinforces the problem.

Shoulder Pain

Frequently driven by poor scapular and humeral control, leading to irritation during reaching, lifting, or workouts.

Knee Pain

Commonly associated with limited hip control or ankle mobility, forcing the knee to absorb stress it wasn’t designed for.

In each case, the painful area is often not the primary problem—it’s the victim of faulty movement elsewhere.

Why Generic Exercises Often Don’t Work

Many rehab programs focus on:

• Strengthening isolated muscles

• Stretching tight areas

• Following a standard protocol

While these can help temporarily, they often fail to address how you move during real life—walking, sitting, lifting, running, or training.

If the underlying movement impairment isn’t corrected, pain tends to return.

How Physical Therapy Should Address MSIs

An MSI-based approach focuses on:

• Detailed movement assessment

• Identifying faulty movement patterns

• Teaching you how to move differently

• Integrating corrections into daily life and activity

This is not about doing more exercises—it’s about doing the right movements, the right way, in the right context.

Why This Matters for Long-Term Relief

When movement is corrected:

• Pain decreases

• Stress on irritated tissues is reduced

• Strength gains actually carry over

• The risk of recurrence drops significantly

This is why two people with the same diagnosis can have very different outcomes.

How Paya Movement Approaches Care

At Paya Movement, every session starts with understanding how you move.

As a mobile, one-on-one physical therapy practice, care is:

• Individualized

• Movement-focused

• Performed in your real environment (home, gym, or outdoors)

The goal isn’t just symptom relief—it’s helping you move better so pain doesn’t keep coming back.

Not Sure If a Movement System Impairment Applies to You?

If your pain:

• Keeps returning

• Improves temporarily but never fully resolves

• Shows up during specific activities or positions

There’s a strong chance movement is playing a role.

A movement assessment can help identify the root cause and guide the next step.

Education is the first step. Changing how you move is what creates lasting results.
