Shoulder Impingement Syndrome: Causes, Symptoms, Treatment & Rehabilitation
Shoulder impingement syndrome is a common cause of shoulder pain, particularly when reaching overhead, lifting, pushing, pulling or lying on the affected side.
The term “shoulder impingement” has traditionally been used to describe pain thought to occur when structures such as the rotator cuff tendons or subacromial bursa become compressed during shoulder movement. However, modern clinical understanding is more nuanced. Many people previously diagnosed with “impingement syndrome” are better described as having subacromial pain syndrome or rotator cuff-related shoulder pain.
Rather than assuming that a particular structure is simply being “pinched”, assessment should consider the person’s symptoms, shoulder strength, movement, activity levels, injury history and ability to tolerate load.
At Vitality Chiropractic Australia in Mill Park, Melbourne, our approach focuses on identifying the factors contributing to your shoulder pain and developing an appropriate treatment and rehabilitation plan to help restore comfortable movement and function.
What Is Shoulder Impingement Syndrome?
Shoulder impingement syndrome is a term commonly used to describe shoulder pain that occurs during movements such as lifting the arm overhead. The symptoms are frequently associated with the rotator cuff tendons and subacromial tissues, but shoulder pain does not necessarily mean that a tendon is being physically trapped or damaged every time you move your arm.
This is an important distinction.
The shoulder is a highly mobile joint that relies on coordinated movement between the:
- Glenohumeral joint
- Scapula (shoulder blade)
- Rotator cuff
- Deltoid
- Thoracic spine
- Acromioclavicular joint
- Surrounding muscles and connective tissues
Pain can develop when the capacity of these tissues is temporarily exceeded by the demands placed upon them. For example, a sudden increase in overhead training, repetitive work, lifting, throwing or gym activity may increase the load on the shoulder faster than the tissues can adapt. The modern approach therefore focuses less on simply “creating more space” in the shoulder and more on reducing excessive irritation while progressively rebuilding strength and load tolerance.
Shoulder Impingement vs Subacromial Pain Syndrome
You may hear several different terms used to describe similar shoulder problems, including:
- Shoulder impingement syndrome
- Subacromial impingement
- Subacromial pain syndrome
- Painful arc syndrome
- Rotator cuff-related shoulder pain
- Rotator cuff tendinopathy
- Supraspinatus tendinopathy
- Shoulder bursitis
These terms overlap, but they are not necessarily interchangeable. The term subacromial pain syndrome is increasingly preferred because it describes the clinical presentation without assuming that mechanical compression is the primary cause of someone’s symptoms. For this reason, a thorough shoulder assessment is more useful than relying on a single “impingement test”.
Symptoms of Shoulder Impingement Syndrome
Symptoms vary between individuals, but common complaints include:
- Pain at the front or outer aspect of the shoulder
- Pain when lifting the arm
- Pain reaching overhead
- Pain putting on or removing clothing
- Pain reaching behind the back
- Pain when reaching across the body
- Difficulty performing gym exercises
- Pain when lying on the affected shoulder
- Night-time shoulder pain
- Reduced shoulder strength
- Reduced confidence using the arm
- Pain during repetitive activities
- Pain after periods of increased activity
Some people describe a painful “arc” when lifting their arm. You may also experience clicking, catching or grinding sensations. These sensations are not necessarily a sign of damage. Clicking can occur in healthy shoulders, so the presence of clicking should be interpreted alongside pain, weakness and functional changes.
Where Does Shoulder Impingement Hurt?
Pain is commonly felt around the:
- Outer shoulder
- Front of the shoulder
- Upper arm
- Area around the deltoid
Some people also experience discomfort around the shoulder blade or upper back. Pain that travels significantly below the elbow, particularly when accompanied by pins and needles, numbness or weakness, may suggest that the neck or nervous system is contributing to the problem rather than the shoulder being the sole source. This is one reason why a complete assessment is important.
What Causes Shoulder Impingement?
Shoulder pain can develop for many different reasons. Often there is no single cause. Common contributing factors include:
Sudden increases in activity
A rapid increase in gym training, swimming, throwing, manual work or overhead activity can place more load through the shoulder than it is currently conditioned to tolerate.
Repetitive overhead activity
Repeated reaching, lifting or overhead work can progressively irritate the rotator cuff and surrounding tissues.
This may occur in occupations such as:
- Painting
- Carpentry
- Electrical work
- Construction
- Warehouse work
- Cleaning
- Hairdressing
It can also occur in recreational activities such as:
- Swimming
- Tennis
- Volleyball
- Baseball
- CrossFit
- Weightlifting
- Functional fitness
Rotator cuff weakness or reduced load capacity
The rotator cuff helps control movement of the upper arm and contributes to shoulder stability. If the shoulder has become deconditioned following injury, inactivity or changes in training, it may have reduced capacity to tolerate normal loads.
Previous shoulder injury
Previous dislocation, tendon injury, fracture or other shoulder trauma can alter how the shoulder is used and loaded.
Reduced shoulder mobility
Restrictions in shoulder or thoracic movement may alter how someone performs overhead movements. However, reduced mobility is not automatically the cause of shoulder pain and should be interpreted alongside the person’s symptoms and functional limitations.
Age-related tendon changes
Rotator cuff tendon changes become increasingly common with age. Importantly, structural changes on ultrasound or MRI do not automatically mean that they are responsible for someone’s pain. Some people have rotator cuff abnormalities without experiencing any symptoms.
Training errors
Shoulder pain can sometimes occur when training volume, intensity or exercise selection changes too quickly.
Examples include suddenly increasing:
- Bench press volume
- Overhead pressing
- Lateral raises
- Pull-ups
- Dips
- Swimming distance
- Throwing volume
When Is Shoulder Pain Most Noticeable?
Shoulder impingement-type pain is often aggravated by:
Overhead movements
Reaching into a cupboard, hanging washing or lifting an object overhead may reproduce symptoms.
Gym exercises
Common aggravating exercises include:
- Overhead press
- Lateral raises
- Bench press
- Dips
- Pull-ups
- Push-ups
- Upright rows
This does not mean that these exercises are permanently “bad” for the shoulder. Instead, they may temporarily exceed your current capacity. With appropriate rehabilitation, many people can progressively return to these movements.
Sleeping
Pain when lying on the affected shoulder is common. Some people also experience increased discomfort during the night even when they are not directly lying on the painful side.
How Is Shoulder Impingement Diagnosed?
There is no single test that can definitively diagnose shoulder impingement. A clinical assessment should combine your history with physical examination findings. At Vitality Chiropractic Australia, your assessment may include:
1. Detailed History
We will ask about:
- When your symptoms started
- Whether there was an injury
- Your pain location
- What movements aggravate your symptoms
- Your occupation
- Exercise and sporting activities
- Previous shoulder problems
- Night-time symptoms
- Changes in training or workload
- Neck symptoms
- Neurological symptoms
Understanding what changed before the shoulder became painful can provide valuable information.
2. Shoulder Range of Motion
We may assess active and passive movement including:
- Flexion
- Extension
- Abduction
- Internal rotation
- External rotation
The objective is not simply to determine whether movement is “normal”. We also consider whether a particular movement reproduces your familiar symptoms.
3. Strength Testing
Rotator cuff and shoulder strength may be assessed to identify:
- Pain inhibition
- Weakness
- Side-to-side differences
- Reduced load tolerance
- Difficulty controlling movement
4. Scapular and Thoracic Movement
The shoulder blade and thoracic spine contribute to normal shoulder movement. We may therefore assess how the scapula moves during elevation and other functional tasks. This does not mean that a particular scapular position is necessarily “wrong”. Instead, we are interested in whether movement is coordinated, comfortable and appropriate for the task.
5. Cervical Spine Assessment
Neck problems can sometimes produce pain around the shoulder. A cervical assessment may therefore be appropriate, particularly when shoulder symptoms are accompanied by:
- Neck pain
- Arm pain
- Pins and needles
- Numbness
- Altered sensation
- Weakness
6. Orthopaedic Testing
A combination of shoulder tests may be used to help determine whether symptoms are consistent with rotator cuff-related shoulder pain or another shoulder condition. No individual test should be interpreted in isolation.
Does Shoulder Impingement Require An MRI Or Ultrasound?
Not necessarily. Imaging is not routinely required for every person with shoulder pain. Ultrasound or MRI may become appropriate when:
- Symptoms are severe
- There is significant weakness
- A substantial traumatic injury has occurred
- A rotator cuff tear is suspected
- Symptoms are not improving as expected
- The diagnosis remains unclear
- The findings would change management
Importantly, imaging findings need to be interpreted alongside the clinical presentation. Rotator cuff tendon changes are common, particularly as people get older, and not every abnormality seen on an MRI or ultrasound is the source of pain.
Conditions That Can Mimic Shoulder Impingement
Not all shoulder pain is caused by rotator cuff-related problems. Other conditions that may produce similar symptoms include:
Rotator cuff tendinopathy
Pain and reduced load tolerance involving one or more rotator cuff tendons.
Rotator cuff tear
A partial or full-thickness tear may occur following trauma or progressive tendon changes. Significant weakness following an acute injury requires appropriate medical assessment.
Subacromial bursitis
Irritation of the subacromial bursa can contribute to shoulder pain.
Adhesive capsulitis
Also known as frozen shoulder, this typically causes progressively restricted shoulder movement, often involving both active and passive range of motion.
Glenohumeral osteoarthritis
Joint degeneration can cause pain, stiffness and reduced shoulder movement.
Acromioclavicular joint pain
The AC joint can produce pain at the top of the shoulder, particularly with cross-body movements or certain lifting activities.
Shoulder instability
Previous dislocation, recurrent subluxation or instability may cause pain and apprehension during certain movements.
Cervical radiculopathy
Irritation of a nerve root in the neck can cause pain, tingling, numbness or weakness extending into the shoulder and arm.
Referred pain
Problems elsewhere in the body can occasionally produce pain around the shoulder. A good shoulder assessment therefore needs to consider the person rather than simply assigning every painful overhead movement to “impingement”.
Treatment For Shoulder Impingement Syndrome
The most important component of modern conservative management is generally progressive rehabilitation. The 2025 clinical practice guideline for rotator cuff tendinopathy supports exercise-based rehabilitation as a key component of treatment, with management tailored to the individual’s symptoms, goals and functional requirements.
Treatment may include:
Pain Management
Initially, the goal may be to reduce irritation enough to allow you to move and exercise comfortably.
This may involve:
- Temporary modification of aggravating activities
- Relative rest
- Appropriate exercise selection
- Manual therapy
- Soft tissue techniques
- Advice regarding sleep positions
- Coordination with your GP or other healthcare professional when medication is appropriate
The objective is not necessarily complete rest. In most cases, the shoulder needs an appropriate amount of movement and loading to progressively rebuild capacity.
Shoulder Mobility Exercises
If shoulder movement is restricted, appropriate mobility exercises may form part of your rehabilitation. Depending on your assessment, these may include:
- Assisted shoulder flexion
- Shoulder rotation exercises
- Thoracic mobility
- Wall slides
- Controlled reaching exercises
Mobility exercises should be selected according to your presentation. More stretching is not automatically better.
Rotator Cuff Strengthening
Progressive strengthening is an important part of rehabilitation.
Exercises may target:
- External rotation
- Internal rotation
- Shoulder elevation
- Scapular control
- Deltoid strength
- General upper-limb strength
Exercises can initially be performed using low resistance before progressively increasing the load. As symptoms improve, rehabilitation should gradually transition from isolated exercises towards more functional movements.
Scapular Strength & Control
The scapula plays an important role in shoulder movement. Depending on your individual needs, rehabilitation may include exercises targeting:
- Serratus anterior
- Middle trapezius
- Lower trapezius
- Rotator cuff
- Deltoid
Examples may include:
- Wall slides
- Serratus punches
- Resistance-band rows
- Scapular elevation exercises
- Controlled overhead movements
The goal is not to force the shoulder blade into one “perfect” position. Instead, rehabilitation aims to improve the shoulder’s ability to control and tolerate movement.
Gradual Return To Overhead Activity
Avoiding overhead activity indefinitely is rarely the goal. Instead, rehabilitation should progressively expose the shoulder to the movements required for your:
- Job
- Sport
- Gym training
- Hobbies
- Daily activities
For example, someone who wants to return to overhead pressing may progress from:
Pain-limited movement → light resistance → moderate resistance → heavier resistance → sport or work-specific loading
The exact progression depends on symptoms, strength and functional goals.
Can Chiropractic Help Shoulder Impingement?
Chiropractic care may form part of a broader conservative rehabilitation program for selected patients with shoulder pain.
Treatment may include:
- Shoulder joint mobilisation
- Thoracic mobilisation
- Cervical mobilisation when clinically appropriate
- Soft tissue therapy
- Exercise prescription
- Load-management advice
- Movement retraining
Manual therapy can sometimes provide short-term improvements in pain or movement, but it should generally be viewed as an adjunct to active rehabilitation rather than a replacement for strengthening and progressive loading. The long-term goal is to help you regain the capacity to use your shoulder confidently rather than becoming dependent on passive treatment.
What About “Correcting” Shoulder Alignment?
You may see shoulder impingement treatment marketed around “fixing posture”, “realigning the shoulder” or “creating space”. These explanations can be overly simplistic. Shoulder movement is dynamic and varies naturally between individuals. There is not necessarily one perfect shoulder position that prevents pain.
Instead, we look at the interaction between:
- Strength
- Mobility
- Coordination
- Training load
- Work demands
- Recovery
- Previous injury
- Individual anatomy
- Pain sensitivity
This provides a more useful framework for rehabilitation.
Should You Stop Training?
Usually, not completely.
In many cases, the better approach is to temporarily modify activities that significantly aggravate symptoms while continuing to train within a tolerable range.
For example, you may be able to continue:
- Lower-body training
- Cardio
- Pain-free pulling exercises
- Modified pressing
- Rotator cuff exercises
- Core training
while temporarily reducing the volume or intensity of painful movements. Your rehabilitation should progressively increase what your shoulder can tolerate.

How Long Does Shoulder Impingement Take To Improve?
Recovery time varies considerably. Some people improve within several weeks, while others require several months of progressive rehabilitation. Factors that can influence recovery include:
- How long symptoms have been present
- Severity of symptoms
- Previous shoulder injuries
- Rotator cuff strength
- Current activity levels
- Work demands
- Sleep quality
- Training load
- Consistency with rehabilitation
- Other shoulder or neck conditions
A shoulder that has been painful for six months should not necessarily be expected to recover in a few days. The important consideration is whether function, strength and symptom tolerance are progressively improving.
When Should You See A Doctor?
Shoulder pain should be medically assessed when there are concerning features such as:
- Significant trauma
- Sudden inability to lift the arm
- Marked or rapidly developing weakness
- Obvious deformity
- Suspected dislocation
- Severe pain following a fall
- Persistent night pain that is unexplained
- Fever or systemic illness
- Significant swelling or redness
- Unexplained weight loss
- Chest pain or shortness of breath
- Neurological symptoms that are worsening
Following a significant traumatic injury, a substantial rotator cuff tear or fracture may need to be excluded.
If symptoms are persistent, worsening or not responding as expected to conservative care, further investigation or referral may be appropriate.
