What is Frozen Shoulder? Understanding Adhesive Capsulitis

Frozen shoulder, also known as adhesive capsulitis, is a shoulder condition that is characterized by stiffness and a reduced range of motion in the shoulder joint. It typically progresses through distinct stages and can last from several months to a few years.

This condition affects approximately 2-5% of the population, with women being more commonly affected than men, particularly those between the ages of 40-60. While the exact cause isn't always clear, understanding the condition, its progression, and treatment options can help you navigate this challenging journey toward recovery.

In this comprehensive guide, we'll explore everything you need to know about frozen shoulder and provide you with exercises and strategies to manage this condition effectively.

Understanding Frozen Shoulder

What Happens in Frozen Shoulder?

Frozen shoulder occurs when the shoulder capsule – the connective tissue that surrounds the shoulder joint – becomes thick, tight, and inflamed. This leads to the formation of adhesions (scar tissue) that restrict movement and cause pain.

Anatomy of the Shoulder:

Key Structures Affected:

• Shoulder capsule: Connective tissue surrounding the joint
• Synovial membrane: Lines the inside of the capsule
• Synovial fluid: Lubricates the joint for smooth movement
• Glenohumeral joint: Ball-and-socket joint of the shoulder

The Adhesive Process:

1. Inflammation: The shoulder capsule becomes inflamed
2. Scar tissue formation: Adhesions develop within the capsule
3. Capsular thickening: The capsule becomes tight and restricts movement
4. Pain and stiffness: Movement becomes limited and painful

The Three Stages of Frozen Shoulder

Stage 1: Freezing Stage (2-9 months)

Characteristics:

• Gradual onset of shoulder pain
• Pain worsens over time, especially at night
• Range of motion begins to decrease
• Pain may radiate down the arm

Symptoms:

• Difficulty reaching overhead
• Pain when lying on the affected side
• Stiffness that gets progressively worse
• Aching pain that may be constant

What's Happening:

• Synovial membrane becomes inflamed
• Pain receptors become highly sensitive
• Early adhesion formation begins
• Capsule starts to thicken

Stage 2: Frozen Stage (4-12 months)

Characteristics:

• Pain may actually decrease compared to Stage 1
• Severe stiffness and limited range of motion
• Daily activities become significantly challenging
• Sleep disturbances continue

Symptoms:

• Marked restriction in all shoulder movements
• Difficulty with basic activities (dressing, reaching)
• Less pain but more functional limitation
• Muscle weakness from disuse

What's Happening:

• Extensive adhesion formation
• Capsule becomes significantly thickened
• Joint space may be reduced
• Surrounding muscles begin to weaken

Stage 3: Thawing Stage (12-24+ months)

Characteristics:

• Gradual improvement in range of motion
• Pain continues to decrease
• Function slowly returns
• May take 1-3 years for complete recovery

Symptoms:

• Slowly increasing shoulder movement
• Improved ability to perform daily activities
• Decreased pain and stiffness
• Gradual return of strength

What's Happening:

• Adhesions begin to stretch and break down
• Capsule starts to loosen
• Inflammation subsides
• Normal tissue healing begins

Causes and Risk Factors

Primary Frozen Shoulder:

Idiopathic Adhesive Capsulitis:

• No clear underlying cause
• Most common type (about 90% of cases)
• Often develops spontaneously
• May be related to autoimmune factors

Secondary Frozen Shoulder:

Underlying Conditions:

• Diabetes: 10-20% of diabetics develop frozen shoulder
• Thyroid disorders: Both hyper and hypothyroidism
• Cardiovascular disease: Heart disease and stroke
• Autoimmune conditions: Rheumatoid arthritis, lupus

Traumatic Causes:

• Shoulder injury or surgery
• Prolonged immobilization
• Rotator cuff tears
• Fractures around the shoulder

Risk Factors:

Demographic Factors:

• Age: 40-60 years old
• Gender: Women more affected than men (2:1 ratio)
• Occupation: Sedentary work or repetitive overhead activities

Medical Factors:

• Diabetes mellitus (strongest risk factor)
• Thyroid dysfunction
• Cardiovascular disease
• Previous shoulder surgery or injury
• Prolonged bed rest or arm immobilization

Diagnosis and Assessment

Clinical Evaluation:

At M.O. Therapy, our comprehensive assessment includes:

History Taking:

• Rule out rotator cuff tears
• Assess for other shoulder pathology

Ultrasound:

• Dynamic assessment of shoulder movement
• Evaluate soft tissue structures
• Guide injection procedures if needed
