Frozen Shoulder: the Functional Path to Recovery 

Frozen Shoulder: Understanding the Anatomy and the Functional Path to Recovery 

Stiffness. Pain. Frustration.
If you feel like your shoulder is slowly “locking up,” you may be dealing with Frozen Shoulder, also known as Adhesive Capsulitis. It’s a condition that limits your mobility—not just physically, but in daily life, work, and sleep. 

But here’s the thing: while frozen shoulder feels isolated to the shoulder joint, it’s often caused—and complicated—by movement dysfunctions throughout the body. 

In this post, we’ll explore the anatomy of frozen shoulder, how full-body mobility plays a role in its development, and how Applied Functional Science™ (AFS) physical therapy can help restore freedom and function. 

What Is Frozen Shoulder (Adhesive Capsulitis)? 

Frozen shoulder is a condition where the capsule surrounding the shoulder joint becomes inflamed, thickened, and tight, severely restricting motion. Over time, this leads to pain, stiffness, and progressive loss of function. 

The 3 Stages of Frozen Shoulder: 

1. Freezing Phase (Painful) 

• Gradual onset of pain 

• Increasing stiffness 

1. Frozen Phase (Stiff) 

• Pain may decrease 

• Significant limitation in motion 

1. Thawing Phase (Recovery) 

• Slow return of motion 

• Requires consistent mobility restoration 

Key Structures Affected: 

• Joint capsule – thickens and restricts movement 

• Synovial fluid – may decrease, reducing lubrication 

• Rotator cuff and surrounding muscles – weaken due to disuse 

The Hidden Contributors: Full-Body Mobility Limitations 

While frozen shoulder symptoms are concentrated in the shoulder, the body-wide movement system often plays a critical role in its development and healing. 

Common Contributing Factors: 

1. Poor Thoracic Spine Mobility

Your mid-back must extend and rotate for full overhead arm movement. A stiff thoracic spine forces the shoulder to strain into positions it's not ready to handle—contributing to inflammation and eventual capsule tightening. 

2. Core and Pelvic Instability

Functional arm movement begins with trunk control. If your core or pelvis isn't supporting shoulder motion properly, your shoulder must work harder just to stabilize—making it vulnerable to fatigue and protective stiffness. 

3. Previous Injury or Immobility

After surgery, injury, or prolonged rest, your shoulder’s natural movement rhythm is interrupted. Scar tissue builds. The joint becomes less lubricated. This often triggers the freezing phase. 

4. Compensations in the Lower Body

Restricted ankle, hip, or foot mobility changes how your body moves when walking, reaching, or rotating—leading to poor loading patterns and asymmetry that increase stress on the shoulder capsule. 

How Applied Functional Science™ (AFS) Heals Frozen Shoulder 

At Superior Physical Therapy, we don’t isolate the shoulder—we assess the entire kinetic chain. That’s the foundation of Applied Functional Science™: understanding how all joints and systems interact to create functional movement. 

Here’s How AFS Addresses Frozen Shoulder: 

1. Whole-Body Movement Analysis

We evaluate your full movement system—from feet to hips to spine to shoulder—identifying hidden restrictions and compensation patterns that are keeping your shoulder “frozen.” 

2. Gentle Functional Mobility Progressions

We use safe, progressive movements that improve: 

• Thoracic spine flexibility 

• Rib cage expansion 

• Scapular mobility 

• Pain-free joint motion 

Even if the shoulder can’t move much yet, we begin mobilizing around it to reduce threat and restore integrated function. 

3. Neuromuscular Reeducation

Frozen shoulder causes faulty movement habits. We retrain the nervous system to move more efficiently by: 

• Improving timing and coordination 

• Activating underused muscles 

• Reinforcing proper shoulder mechanics with the rest of the body 

4. Functional Strengthening & Load Integration

As motion improves, we load the shoulder in real-life movements—walking with arm swings, reaching in 3D planes, and restoring your ability to lift, twist, and push confidently. 

Why This Approach Works 

Traditional frozen shoulder treatment often emphasizes passive stretching or waiting it out. But AFS offers a proactive and personalized approach that: 

Avoids over-stressing a sensitive joint
Improves motion above and below the shoulder
Treats the root cause, not just the symptoms
Promotes long-term, sustainable recovery 

Patient Success Spotlight: 

"I could barely lift my arm to brush my hair. I thought it would take a year to get better—but within a few weeks of functional therapy, I could move again. The difference was treating my whole body, not just my shoulder."
— Mary, age 56, post-op patient
