Frozen Shoulder

Frozen shoulder is a condition where the shoulder joint becomes stiff, painful, and difficult to move due to inflammation and tightening of the joint capsule. The condition develops gradually and can significantly affect daily activities such as dressing, lifting, or reaching overhead. Physiotherapy is one of the most effective treatments for frozen shoulder, helping reduce pain, improve mobility, and restore normal shoulder function.

What is Frozen Shoulder?

Frozen shoulder, medically known as adhesive capsulitis, is a condition where the capsule surrounding the shoulder joint becomes inflamed, thickened, and tight. This leads to restricted shoulder movement and persistent pain.

The shoulder joint normally has a flexible capsule that allows a wide range of motion. In frozen shoulder, inflammation causes the capsule to tighten and develop adhesions (scar-like tissue), limiting movement.

Frozen shoulder usually develops slowly and may progress through three stages:

Freezing stage Pain gradually increases and shoulder movement becomes more restricted.

Frozen stage Pain may reduce slightly, but stiffness becomes more severe and movement is significantly limited.

Thawing stage Shoulder movement gradually improves as the joint begins to recover.

Without treatment, this condition can take months or even years to fully resolve.

How Does Frozen Shoulder Happen?

The exact cause of frozen shoulder is not always clear, but several factors may increase the risk.

Common causes and risk factors include:

  • Shoulder injury or surgery
  • Prolonged shoulder immobilisation
  • Diabetes
  • Thyroid disorders
  • Age (most common between 40–60 years)
  • Previous shoulder inflammation

The condition often develops when the shoulder joint becomes irritated and the capsule surrounding the joint becomes inflamed.

What Are the Symptoms of Frozen Shoulder?

Frozen shoulder usually develops gradually and symptoms worsen over time.

Common symptoms include:

  • Persistent shoulder pain
  • Gradual loss of shoulder movement
  • Stiffness in the shoulder joint
  • Difficulty lifting the arm overhead
  • Pain when reaching behind the back
  • Pain that worsens at night
  • Weakness in the shoulder muscles
  • Muscle spasms around the shoulder
  • Occasional clicking in the joint

Pain is often felt deep within the shoulder and may radiate down the outer upper arm.

What Should I Do If I Have Frozen Shoulder?

If you suspect frozen shoulder, it is important to seek assessment from a physiotherapist or healthcare professional.

Early diagnosis and treatment can help:

  • Reduce pain
  • Prevent worsening stiffness
  • Restore shoulder mobility faster

A healthcare professional may perform physical examination and imaging tests (such as X-rays or ultrasound) to rule out other shoulder conditions.

Physiotherapy Treatment for Frozen Shoulder

Physiotherapy is one of the most effective treatments for frozen shoulder and focuses on restoring movement and reducing pain.

At ACE Physio Sports in Singapore, physiotherapists create personalised treatment plans designed to gradually improve shoulder function.

Physiotherapy treatment may include:

  • Range-of-motion exercises to improve shoulder flexibility
  • Stretching exercises to reduce capsular tightness
  • Strengthening exercises for shoulder and upper back muscles
  • Postural correction training
  • Manual therapy techniques to improve joint movement
  • Soft tissue therapy to reduce muscle tension
  • Electrotherapy to manage pain and inflammation
  • Acupuncture in selected cases

Patients are also given home exercise programmes to continue rehabilitation between sessions.

In some cases, a corticosteroid injection may be recommended to reduce inflammation and improve mobility.

What Should I Avoid With Frozen Shoulder?

Certain activities may worsen symptoms during recovery.

Patients should avoid:

  • Ignoring persistent shoulder pain
  • Forcing painful shoulder movements
  • Sudden overhead lifting
  • Heavy lifting with the affected arm
  • Delaying physiotherapy treatment

Early treatment can significantly shorten recovery time.

Can There Be Long-Term Effects?

Frozen shoulder often improves over time, but recovery can take several months to a year without treatment.

Possible long-term effects may include:

  • Persistent shoulder stiffness
  • Reduced shoulder mobility
  • Muscle weakness
  • Difficulty performing overhead activities

With early physiotherapy and consistent rehabilitation, most patients make a full recovery and regain normal shoulder function.

Frequently Asked Questions

Why does my shoulder hurt when I lift my arm above my head?

Overhead pain is one of the most common shoulder complaints and can be caused by conditions like Frozen Shoulder. It often involves impingement of tendons or bursa in the subacromial space. Physiotherapy addresses the root cause through posture correction and progressive rotator cuff strengthening.

Can physiotherapy fix my shoulder problem without surgery?

Most shoulder conditions — including Frozen Shoulder — respond very well to physiotherapy. Treatment may include manual therapy, rotator cuff exercises, and scapular stabilisation. Surgery is considered only when conservative treatment has been given a full, consistent trial.

How long before I can sleep on my shoulder again?

Sleeping on the affected side is often the last comfort to return during shoulder rehabilitation. Most patients regain this within 4–8 weeks as pain and inflammation settle. A firmly placed pillow under the arm can help in the meantime.
