Adhesive Capsulitis (Frozen Shoulder): Symptoms, Stages, Causes & Treatment
Frozen shoulder can make simple movements like reaching overhead, putting on a shirt or reaching behind your back surprisingly difficult. Adhesive capsulitis is a condition characterised by progressive shoulder pain and significant restriction of both active and passive shoulder movement.
At Vitality Chiropractic Australia, we take a movement-based, rehabilitation-focused approach to frozen shoulder. Our assessment looks beyond the painful shoulder to consider the neck, upper back, shoulder blade and overall movement patterns that may be contributing to reduced function.
If you have noticed that your shoulder is becoming increasingly painful and stiff — particularly if you are losing the ability to rotate your arm or reach behind your back — an accurate assessment is important.
What Is Frozen Shoulder?
Adhesive capsulitis, commonly called frozen shoulder, occurs when the capsule surrounding the shoulder joint becomes thickened, inflamed and increasingly restricted.
The shoulder is a ball-and-socket joint designed to provide a very large range of movement. In frozen shoulder, changes within the joint capsule progressively restrict this movement.
One of the most important clinical features is that both active and passive shoulder movement become restricted. In other words, the shoulder remains difficult to move even when someone else attempts to move it for you.
This distinguishes frozen shoulder from many other causes of shoulder pain, where strength or pain may limit active movement but passive movement remains relatively preserved.
Frozen shoulder commonly develops between the ages of 40 and 60 and is more common in women. People with diabetes or thyroid disorders have an increased risk, while previous shoulder injury, surgery or prolonged immobilisation can also contribute.
Frozen Shoulder Symptoms
Frozen shoulder symptoms usually develop gradually rather than appearing as one sudden injury. Common symptoms include:
- Increasing shoulder pain
- Shoulder stiffness
- Progressive loss of range of motion
- Difficulty reaching overhead
- Difficulty reaching behind your back
- Difficulty putting on or removing clothing
- Difficulty reaching into a back pocket
- Pain when sleeping on the affected side
- Shoulder pain that is worse at night
- Difficulty performing normal household or work activities
- A feeling that the shoulder is becoming progressively “stuck”
A particularly important symptom is loss of external rotation — the ability to rotate your arm outward. For many people, movements such as putting on a jacket, fastening clothing or reaching behind the head become increasingly difficult.
The 3 Stages of Frozen Shoulder
Frozen shoulder typically progresses through three broad stages. The duration of each stage varies considerably between individuals, so these timeframes should be considered approximate rather than rigid.
Stage 1 – Freezing Phase
The freezing phase is generally the most painful stage. Shoulder pain gradually increases and movement becomes progressively more restricted. You may notice:
- Increasing pain with movement
- Pain at rest
- Night pain
- Difficulty sleeping
- Increasing difficulty reaching overhead
- Gradual loss of shoulder mobility
This stage can last several weeks to many months. AAOS reports that the freezing stage can typically last approximately 6 weeks to 9 months.
The key priority during the freezing phase
The goal is generally not to aggressively force the shoulder through painful ranges. Instead, management should focus on controlling symptoms while maintaining as much comfortable movement as possible. Depending on the individual, this may involve gentle mobility work, appropriate manual therapy, activity modification and medical management where required.
Stage 2 – Frozen Phase
During the frozen phase, pain may begin to settle, but stiffness becomes the dominant problem.
You may find that:
- The shoulder feels extremely stiff
- Reaching overhead is difficult
- Reaching behind your back is very restricted
- Putting on clothing becomes challenging
- Shoulder rotation is significantly reduced
- Daily activities take considerably more effort
This is often the stage where people describe their shoulder as feeling “stuck.”
The frozen phase can last several months.
The key priority during the frozen phase
As irritability decreases, the focus generally shifts increasingly towards restoring mobility and function. This is where an appropriately progressed rehabilitation program becomes particularly important.
Stage 3 – Thawing Phase
The thawing phase is the gradual recovery stage.
Shoulder movement begins to improve and everyday activities progressively become easier.
Recovery can be slow, however.
Some people regain normal or near-normal function relatively quickly, while others experience residual stiffness for considerably longer.
AAOS notes that complete recovery can take up to three years in some cases.
The important message is that frozen shoulder is usually a gradual recovery process rather than an injury that can simply be “fixed” in one or two treatments.
A structured rehabilitation plan can help you progressively restore movement, strength and confidence in using the shoulder.
What Causes Frozen Shoulder?
There are two broad categories of adhesive capsulitis.
Primary Frozen Shoulder
Primary, or idiopathic, adhesive capsulitis develops without an obvious initiating injury or event.
The exact cause is not always known.
Secondary Frozen Shoulder
Secondary adhesive capsulitis develops in association with another event or condition.
Potential contributors include:
- Previous shoulder injury
- Shoulder surgery
- Prolonged immobilisation
- Reduced shoulder movement
- Diabetes
- Thyroid disorders
- Other systemic health conditions
Diabetes is particularly strongly associated with frozen shoulder. This is one reason our assessment considers your overall health history, previous injuries and current activity levels, rather than examining the shoulder in isolation.
Is Frozen Shoulder the Same as a Rotator Cuff Injury?
No. Frozen shoulder and rotator cuff conditions can produce overlapping symptoms, but they are different problems. A rotator cuff disorder may cause:
- Shoulder pain
- Weakness
- Pain with lifting
- Pain with overhead activities
- Difficulty sleeping on the affected shoulder
Frozen shoulder, on the other hand, is characterised by a much more pronounced loss of both active and passive shoulder movement.
You can learn more about these conditions on our Rotator Cuff Syndrome page. This distinction matters because the appropriate rehabilitation strategy can differ significantly.
Frozen Shoulder vs Bursitis
Shoulder bursitis can also cause pain and restricted movement.
However, people with bursitis often retain considerably more passive shoulder movement than someone with true adhesive capsulitis.
You can learn more about shoulder bursitis and other forms of bursitis on our Bursitis page.
A proper clinical examination is therefore important before assuming that shoulder pain and stiffness automatically represent frozen shoulder.
Frozen Shoulder vs Shoulder Osteoarthritis
Glenohumeral osteoarthritis can also produce:
- Shoulder pain
- Stiffness
- Reduced range of motion
- Difficulty with everyday activities
However, osteoarthritis involves degenerative changes within the joint and may be identified through appropriate imaging.
How Is Frozen Shoulder Diagnosed?
Frozen shoulder is primarily a clinical diagnosis. Your practitioner will assess the pattern of your symptoms and determine how your shoulder moves. A comprehensive assessment may include:
Shoulder Range of Motion
We assess both active and passive movement. Particular attention is paid to:
- External rotation
- Internal rotation
- Flexion
- Abduction
- Functional reaching movements
Strength Testing
Strength testing can help identify weakness and differentiate frozen shoulder from conditions such as rotator cuff pathology.
Orthopaedic Testing
Specific shoulder tests may help identify alternative or coexisting shoulder conditions.
Cervical Spine Assessment
Shoulder pain can sometimes originate from the neck. We may therefore assess your cervical spine and neurological function where appropriate to determine whether cervical nerve irritation or referred pain could be contributing to your symptoms.
Thoracic Spine and Scapular Assessment
The upper back and shoulder blade play important roles in normal shoulder movement. Restricted thoracic mobility or altered scapular mechanics may influence how the shoulder moves and functions.
Functional Assessment
We may also assess movements relevant to your everyday life, such as:
- Reaching overhead
- Reaching behind your back
- Dressing
- Lifting
- Sleeping positions
- Work-related movements
- Sporting activities
Do You Need an MRI or X-Ray for Frozen Shoulder?
Not necessarily. Frozen shoulder is usually diagnosed clinically.
Imaging may be recommended when the clinical presentation is unusual, symptoms are not progressing as expected, significant trauma has occurred, or another condition needs to be ruled out.
For example, imaging may be useful when there is concern about:
- Significant osteoarthritis
- Rotator cuff tear
- Fracture
- Dislocation
- Other structural abnormalities
At Vitality Chiropractic Australia, imaging is recommended when clinically indicated rather than automatically for every musculoskeletal complaint.
What About Cortisone Injections?
Corticosteroid injections may be considered by medical practitioners, particularly when pain and inflammation are significant during the earlier stages.
They can provide short-term improvements in pain and function for some patients.
If pain is severe or significantly affecting sleep and daily function, discussing medical treatment options with your GP or appropriate medical practitioner may be worthwhile.
Other medical interventions, including hydrodilatation, may also be considered in selected cases.
Treatment for Frozen Shoulder
There is no single treatment that is appropriate for every stage of adhesive capsulitis.
Treatment should be guided by:
- The stage of the condition
- Pain severity
- Irritability
- Current range of motion
- Functional limitations
- Previous treatment
- General health
- Your individual recovery goals
The primary conservative objective is to manage pain while progressively restoring shoulder movement and function. AAOS identifies physical therapy and shoulder flexibility exercises as important components of conservative frozen shoulder management.
At Vitality Chiropractic Australia, treatment may include a combination of:
Chiropractic Care
Appropriate chiropractic techniques may be used to address mobility restrictions involving the:
- Shoulder girdle
- Thoracic spine
- Cervical spine
- Adjacent joints
Treatment is tailored to the individual and the current irritability of the condition.
Shoulder Mobilisation
Gentle or appropriately progressed mobilisation techniques may be used to help improve joint movement. The intensity and direction of mobilisation should be matched to the patient’s stage of frozen shoulder rather than simply forcing the shoulder into painful positions.
Soft Tissue Therapy
Soft tissue techniques may be used to address muscular tension around the:
- Rotator cuff
- Deltoid
- Pectoral muscles
- Upper trapezius
- Levator scapulae
- Scapular stabilisers
These techniques are generally used as an adjunct to active rehabilitation rather than as a replacement for it.
Exercise Rehabilitation
Exercise is a major component of long-term recovery. Depending on the stage of your condition, rehabilitation may include:
- Gentle range-of-motion exercises
- Shoulder rotation exercises
- Pendulum exercises
- Thoracic mobility exercises
- Scapular control exercises
- Progressive strengthening
- Functional movement retraining
The objective is to gradually restore usable movement without repeatedly aggravating the shoulder.
Posture and Thoracic Mobility
Shoulder movement does not occur in isolation. The thoracic spine and scapula contribute significantly to normal overhead and reaching movements. For patients who also have significant postural or upper-back restrictions, addressing these areas can form part of the overall rehabilitation strategy. Learn more about our approach to posture correction and rehabilitation.
What About Surgery?
Most people with frozen shoulder do not require surgery.
When significant stiffness and disability persist despite appropriate conservative management, an orthopaedic specialist may consider procedures such as:
- Manipulation under anaesthesia
- Arthroscopic capsular release
These procedures are generally reserved for selected patients who have not responded adequately to non-surgical management.
Following any procedure, rehabilitation remains important to maintain the movement achieved.
The Vitality Frozen Shoulder Recovery Plan – Coming Soon
Our dedicated Frozen Shoulder Rehabilitation Program is coming soon. This program will be designed to provide patients with a structured progression from pain and stiffness management through to restored shoulder mobility, strength and function.
The program will focus on:
- Stage-specific shoulder mobility
- External and internal rotation
- Thoracic mobility
- Scapular control
- Rotator cuff strengthening
- Progressive functional exercises
- Home rehabilitation
- Tracking improvements in shoulder movement
Rather than simply providing a collection of stretches, the aim will be to create a progressive rehabilitation pathway that reflects the changing needs of the frozen shoulder throughout recovery.
Frozen Shoulder Rehabilitation: What Should You Expect?
One of the biggest mistakes people make with frozen shoulder is expecting rapid results.
Adhesive capsulitis is usually a slow-moving condition.
Your rehabilitation should therefore focus on progressive improvements rather than trying to force a rapid change in range of motion.
A typical rehabilitation strategy may progress through:
Phase 1 – Pain & Irritability Management
The initial priority is to:
- Reduce aggravating activities
- Improve comfort
- Maintain available movement
- Improve sleep
- Avoid unnecessary shoulder guarding
Phase 2 – Mobility Restoration
As irritability reduces, rehabilitation can increasingly focus on:
- Shoulder range of motion
- External rotation
- Internal rotation
- Overhead movement
- Thoracic mobility
- Scapular movement
Phase 3 – Strength & Function
As movement improves, strengthening becomes increasingly important.
This may include progressive exercises for:
- Rotator cuff strength
- Scapular stabilisation
- Shoulder endurance
- Upper-body strength
- Functional movements
Phase 4 – Return to Normal Activity
The final objective is to restore confidence and function.
Depending on your goals, this may involve returning to:
- Gym training
- Manual work
- Sport
- Swimming
- Overhead activities
- Recreational activities
Products That May Support Frozen Shoulder Rehabilitation
Exercise and professional rehabilitation remain the foundation of recovery. However, selected products can be useful adjuncts for symptom management and home rehabilitation. Depending on your presentation, relevant products from the Vitality Chiropractic Australia online store may include:
Fortress Rubber Trigger Point Ball
A small massage ball can be useful for self-management of muscular tension around the shoulder girdle, upper back and surrounding musculature.
Fortress Vibrating Massage Ball
Vibration may provide a useful adjunct for managing muscular tightness before mobility or rehabilitation work.
Fortress Medium Round Foam Roller
A foam roller can be incorporated into thoracic mobility exercises and upper-back rehabilitation.
Fortress Professional TENS Machine
TENS may be useful for some people as an adjunctive strategy for managing pain, particularly when symptoms interfere with daily activities or sleep.
Important: These products should be viewed as supportive tools rather than treatments that directly resolve adhesive capsulitis. The most important component of recovery remains an appropriately progressed rehabilitation program.
When Should You See a Chiropractor for Frozen Shoulder?
Consider seeking professional assessment if:
- Your shoulder pain is progressively worsening
- Shoulder movement is becoming increasingly restricted
- You are losing the ability to reach overhead
- You cannot comfortably reach behind your back
- Shoulder pain is disturbing your sleep
- You are struggling with dressing or daily activities
- Your shoulder has remained stiff following an injury or surgery
- You are unsure whether you have frozen shoulder, bursitis or rotator cuff pathology
- Your symptoms are not improving as expected
Early assessment can help establish what is actually causing your shoulder restriction and whether additional medical investigation is appropriate.
When Should You See Your GP or Another Medical Professional?
Not every painful shoulder is frozen shoulder.
Medical assessment may be particularly important when there has been:
- Significant trauma
- Suspected fracture or dislocation
- Sudden severe weakness
- Major loss of function
- Significant swelling or redness
- Fever or systemic illness
- Unexplained weight loss
- Persistent unexplained night pain
- Neurological symptoms
- Symptoms that are unusual or rapidly worsening
Where necessary, we can work alongside your GP, physiotherapist, radiologist or orthopaedic specialist.

Frequently Asked Questions About Frozen Shoulder
How long does frozen shoulder last?
Frozen shoulder can take considerably longer to resolve than many common musculoskeletal injuries.
The entire process may take months to several years, depending on the individual. AAOS notes that complete recovery can take up to three years in some cases.
Can frozen shoulder heal by itself?
Yes. Frozen shoulder often improves naturally over time.
However, “self-limiting” does not necessarily mean that you should simply ignore it. Appropriate management can help control pain, maintain movement and improve function during what can otherwise be a prolonged recovery.
What is the best exercise for frozen shoulder?
There is no single best exercise.
The appropriate exercise depends heavily on the stage and irritability of the condition.
An exercise that is appropriate during the thawing stage may be too aggressive during the painful freezing stage.
Can frozen shoulder cause neck pain?
It can. When shoulder movement becomes restricted, people often compensate by changing the way they move their neck, upper back and shoulder blade.
However, neck pain can also be the source of referred shoulder pain, which is why the cervical spine should be considered during assessment.
Will I need surgery?
Most people do not require surgery.
Surgery may be considered in selected cases where significant symptoms and restriction persist despite appropriate non-surgical management.
