Frozen shoulder, also known as adhesive capsulitis, is one of the most frustrating shoulder conditions for patients and clinicians alike. It often begins gradually with shoulder pain and stiffness, then progresses to significant restriction in movement that can affect daily activities such as dressing, reaching overhead, driving, sleeping, and even simple self-care tasks.

Many people describe the shoulder as feeling “stuck” or “locked,” with pain that worsens at night or during movement. Without proper treatment, symptoms may last for many months or even several years.

The good news is that conservative treatment remains the first and most effective line of management for most patients.

Understanding Frozen Shoulder

Adhesive capsulitis occurs when the shoulder joint capsule becomes inflamed, thickened, and tight, leading to pain and reduced range of motion. It commonly affects people between the ages of 40 and 60 and is more frequently seen in individuals with diabetes, thyroid disorders, previous shoulder injuries, or prolonged shoulder immobilization.

Treatment focuses on three main goals:

• Reducing pain
• Restoring shoulder mobility
• Improving functional movement and quality of life

Common Conservative Treatment Options

Recent clinical research highlights four common first-line conservative treatments for frozen shoulder:

1. Suprascapular Nerve Block (SSNB)

This treatment helps reduce pain by blocking pain signals from the suprascapular nerve, one of the major nerves supplying the shoulder. Pain relief can make movement and rehabilitation much easier for patients who are limited by severe discomfort.

2. Intra-Articular Corticosteroid Injection (IACS)

A corticosteroid injection placed directly into the shoulder joint helps reduce inflammation and pain, especially during the painful early stage of frozen shoulder. This often allows patients to begin movement exercises more comfortably.

3. Hydrodilatation

Hydrodilatation involves injecting fluid into the shoulder joint capsule to stretch and expand the tight capsule. This may help improve joint mobility and reduce stiffness, particularly in patients with significant movement restriction.

4. Physiotherapy

Physiotherapy remains one of the most important parts of treatment. It focuses on improving range of motion, restoring shoulder mechanics, reducing pain, and gradually returning the patient to normal daily activities.

Why Combination Treatment Works Best

Research shows that combining treatments often produces better outcomes than relying on a single treatment alone.

Strong evidence supports:

• Suprascapular nerve block + Physiotherapy
• Corticosteroid injection + Physiotherapy
• Suprascapular nerve block + Corticosteroid injection

These combinations can significantly improve:

• Pain reduction
• Shoulder range of motion
• Functional use of the arm
• Overall recovery time

Hydrodilatation combined with physiotherapy may also provide additional benefits, particularly for improving movement in stiff shoulders.

This highlights an important principle: frozen shoulder treatment should be individualized. There is no one-size-fits-all solution.

Don’t Wait Too Long

Many patients delay treatment, hoping the shoulder will improve on its own. Unfortunately, frozen shoulder can become much harder to treat once stiffness becomes severe.

If your shoulder feels painful, stiff, or increasingly difficult to move, early assessment can make a major difference.

With the right treatment plan, recovery is possible.
