Frozen Shoulder | PhysioGain

Frozen Shoulder

Struggling to lift your arm or reach behind your back? Learn why frozen shoulder develops, what to expect during recovery, and how physiotherapy can help restore movement safely.

Frozen shoulder causes pain and progressive stiffness of the shoulder joint, making everyday activities such as dressing, reaching overhead, fastening a bra, or sleeping on the affected side increasingly difficult.

QUICK OVERVIEW

Frozen Shoulder at a Glance

InformationDetails
What is it?Frozen shoulder (adhesive capsulitis) is a condition where the shoulder joint capsule becomes inflamed, thickened, and stiff, leading to pain and significant loss of movement.
Common Age GroupMost common between 40–60 years.
Typical Recovery TimeRecovery often takes 12–24 months, although some people recover sooner and some may have residual stiffness.
Common CausesOften develops gradually without a clear cause (primary). It can also occur after shoulder injury, surgery, or prolonged immobilisation (secondary).
Pain LocationDeep shoulder pain, commonly over the outer shoulder and upper arm.
Treatment SuccessMost people improve with conservative treatment, although recovery is often gradual. Surgery is required only for selected individuals with persistent stiffness.

COMMON SIGNS & SYMPTOMS

Is This What You're Feeling?

📈

Progressive Shoulder Pain

Pain usually begins gradually and worsens over time.

🔒

Severe Stiffness

Difficulty lifting your arm, reaching overhead, or reaching behind your back.

🌙

Pain at Night

Pain often disrupts sleep, particularly when lying on the affected shoulder.

👕

Difficulty Dressing

Simple tasks such as putting on a shirt, fastening a bra, or putting on a jacket become challenging.

📏

Limited Shoulder Movement

Both active and passive shoulder movement become restricted.

🖐️

Pain While Reaching

Activities such as reaching into a cupboard or washing your hair become difficult.

⚠️

Reduced Function

Everyday activities become increasingly limited due to stiffness rather than weakness alone.

COMMON CAUSES

Why Does It Happen?

Primary (Idiopathic) Frozen Shoulder

Develops without a clearly identifiable cause. The exact reason remains unclear.

🏥

Secondary Frozen Shoulder

May develop after shoulder surgery, fractures, rotator cuff injuries, prolonged immobilisation, or previous shoulder trauma.

🩸

Diabetes

People with diabetes have a significantly higher risk and may experience a longer recovery.

🦋

Thyroid Disorders

Both hypothyroidism and hyperthyroidism are associated with an increased risk.

🛑

Prolonged Immobilisation

Keeping the shoulder still for long periods after injury or surgery may contribute to stiffness.

👴

Age-Related Risk

Frozen shoulder most commonly affects adults between 40 and 60 years of age.

RISK FACTORS

Who Is Most at Risk?

👴

Adults Aged 40–60 Years

The condition is uncommon in younger adults.

🩸

People with Diabetes

One of the strongest known risk factors.

🦋

People with Thyroid Disorders

Higher prevalence compared with the general population.

🏥

Individuals Recovering from Shoulder Injury or Surgery

Periods of reduced shoulder movement increase the risk.

♀️

Women

Frozen shoulder is reported slightly more frequently in women than men.

🔄

Individuals with Previous Frozen Shoulder

Higher chance of developing it in the opposite shoulder.

DIAGNOSIS

How Is It Diagnosed?

Clinical Assessment

Medical History

  • Gradual onset of symptoms
  • Night pain
  • Shoulder stiffness
  • Difficulty with daily activities
  • Previous injuries or surgery
  • Diabetes or thyroid disease
  • Duration of symptoms

Physical Examination

  • Active shoulder movement
  • Passive shoulder movement
  • Functional limitations
  • Pain pattern
  • Shoulder strength (where possible)

Special Tests & Imaging

Special Tests

  • Used primarily to rule out other conditions
  • Rotator cuff tears
  • Shoulder instability
  • Acromioclavicular joint disorders
  • Cervical spine referral

A hallmark feature is a global reduction in both active and passive shoulder range of motion, particularly external rotation.

Imaging

Frozen shoulder is primarily a clinical diagnosis. X-rays may be used to exclude arthritis or fractures. MRI or ultrasound is generally not required unless another condition is suspected.

SEEKING HELP

When Should You Get Help?

🟢

Monitor Symptoms

Appropriate if:

  • Mild stiffness
  • Symptoms are stable
  • Daily activities remain manageable
🟡

Book a Physiotherapy Assessment

Recommended if:

  • Shoulder stiffness progressively worsens
  • Pain affects sleep
  • Difficulty dressing or reaching overhead
  • Symptoms persist for more than two weeks
  • Loss of movement continues to increase
🔴

Seek Urgent Medical Assessment

Seek prompt medical evaluation if you experience:

  • Severe pain following significant trauma
  • Fever with a painful, swollen shoulder
  • Obvious shoulder deformity
  • Sudden inability to move the arm after an injury
  • Progressive numbness or weakness affecting the arm or hand
  • Unexplained weight loss with persistent shoulder pain

TREATMENT

Treatment Options

📚

Education

Understanding the natural course of frozen shoulder and maintaining appropriate shoulder movement are important parts of treatment.

🏋️

Exercise Therapy

Gentle stretching and mobility exercises tailored to the stage of the condition help improve movement while respecting symptom irritability.

👐

Manual Therapy

Joint mobilization may help improve pain and mobility when combined with exercise. The intensity should match the stage of the condition.

💊

Pain Management

Pain-relieving medication may be appropriate under medical supervision to facilitate participation in rehabilitation.

💉

Corticosteroid Injection

Intra-articular corticosteroid injections may provide short-term pain relief, particularly during the early painful stage.

💧

Hydrodilatation

In selected cases, joint capsule distension (hydrodilatation) may be considered after specialist assessment.

🏥

Surgery

Manipulation under anaesthesia or arthroscopic capsular release may be considered for persistent severe stiffness after an adequate trial of conservative management.

PHYSIOTHERAPY

How Physiotherapy Helps

Physiotherapy aims to reduce pain, restore shoulder mobility, improve function, and guide you through each stage of recovery.

Treatment may include:

  • Individualised mobility programme
  • Gentle stretching
  • Joint mobilization when appropriate
  • Pain management strategies
  • Progressive strengthening as movement improves
  • Functional retraining
  • Home exercise programme
  • Education on pacing activities
  • Long-term prevention of shoulder deconditioning

RECOVERY JOURNEY

Recovery Timeline

1
Stage 1: Freezing Phase (2–9 Months)
Increasing pain with gradually worsening stiffness. Treatment focuses on pain control, education, and maintaining gentle movement.
2
Stage 2: Frozen Phase (4–12 Months)
Pain often begins to settle, but stiffness remains significant. Rehabilitation emphasises restoring mobility and maintaining function.
3
Stage 3: Thawing Phase (6–24 Months)
Movement gradually improves, strength returns, and daily activities become easier. Continued exercise supports long-term recovery.

Recovery times vary between individuals and may overlap.

EXERCISE LIBRARY

Recommended Exercises

Pendulum Exercise

Easy

Target: Gentle shoulder mobility

Repetitions: 30–60 seconds × 2–3 sets

Table Slides

Easy

Target: Shoulder flexion mobility

Repetitions: 10–15

Assisted External Rotation with a Stick

Moderate

Target: External rotation mobility

Repetitions: 10 repetitions

Precaution: Stretch gently without forcing into severe pain.

Wall Walks

Moderate

Important: Exercise intensity should be adapted to the stage of frozen shoulder. Aggressive stretching is generally not recommended, particularly during highly irritable phases.

LONG-TERM HEALTH

Prevention Tips

Keep Your Shoulder Moving After Injury

Follow professional guidance to regain movement safely after surgery or injury.

🩸

Manage Medical Conditions

Good control of diabetes and appropriate management of thyroid disorders may reduce the risk of complications.
