Frozen Shoulder Physiotherapy: Causes, Stages, and Treatment

Introduction

Frozen shoulder, or adhesive capsulitis, is a condition that causes pain, stiffness, and limited range of motion in the shoulder. It often develops gradually, severely restricting movement over time. This page explores the causes, stages, and how physiotherapy can effectively manage frozen shoulder, improve shoulder mobility, and relieve pain.

What is Frozen Shoulder?

Frozen shoulder occurs when the capsule surrounding the shoulder joint becomes inflamed and thickened, leading to pain and stiffness. It typically progresses through three stages:

Freezing Stage: Pain increases gradually, and shoulder movement becomes limited.
Frozen Stage: Pain may subside, but the stiffness persists, severely limiting range of motion.
Thawing Stage: Gradual improvement in movement and reduction of stiffness.

This condition can take months to years to resolve without treatment.

Causes and Risk Factors of Frozen Shoulder

The exact cause of frozen shoulder is unknown, but several risk factors increase the likelihood of developing the condition:

Diabetes: People with diabetes are at higher risk.
Immobility: Shoulder immobilization after surgery or injury can lead to frozen shoulder.
Age and Gender: It is more common in individuals aged 40 to 60 and tends to affect women more than men.
Systemic Conditions: Conditions like hypothyroidism, Parkinson's disease, and heart disease may increase the risk.
Surgery: Having recently undergone any surgery to the Shoulder or Armpit area.

Diagnosing Frozen Shoulder

Diagnosis involves a thorough clinical examination and history-taking. Your physiotherapist will assess your shoulder's range of motion, strength, and any compensatory movements.

Common tests include:

Passive Range of Motion (PROM): Testing shoulder movement by your physiotherapist.
Active Range of Motion (AROM): Testing movement you can actively perform.

Differentiating frozen shoulder from other conditions like rotator cuff injuries or osteoarthritis is crucial for proper treatment.

Physiotherapy for Frozen Shoulder

Physiotherapy plays a key role in managing and accelerating recovery from frozen shoulder. Treatment focuses on:

Pain Management: Techniques like manual therapy, heat, and ice can reduce pain and stiffness.
Stretching and Mobility Exercises: Gradual, targeted exercises designed to restore shoulder movement, such as:
- Pendulum stretches
- Cross-body stretches
- External rotation with a resistance band
Strengthening Exercises: Focus on strengthening surrounding muscles to support the shoulder joint as mobility improves.

Each stage of frozen shoulder requires different exercises and approaches. A physiotherapist will tailor your rehabilitation based on which stage you are in.

Does Frozen Shoulder Resolve on Its Own?

Frozen shoulder can improve without intervention, but this process can take anywhere from 1 to 3 years. Physiotherapy may speed up this process. The primary goal is to reduce pain, stiffness and maintain shoulder function while waiting for the condition to resolve naturally.

Preventing Frozen Shoulder

Prevention focuses on maintaining shoulder mobility and function, particularly after injury or surgery. Early physiotherapy intervention and regular mobility exercises can help prevent frozen shoulder from developing or progressing. Based on the risk factors above, we can also say that maintaining the best overall general health is also protective.

When to See a Physiotherapist

If you’re experiencing shoulder pain and stiffness that isn’t improving, it’s important to consult a physiotherapist early. Especially if you have any of the risk factors from above. Early intervention significantly increases the likelihood of faster recovery, prevents long-term complications, and reduces pain.
