Why Some Stroke Survivors Develop Shoulder Pain—and What Can Be Done

Shoulder pain is a common and often frustrating problem during stroke recovery. A person may begin rehabilitation with the hope of regaining movement, only to find that pain in the affected shoulder makes exercises, dressing, bathing, or even sitting comfortably more difficult. 

Post-stroke shoulder pain does not have a single cause. It can develop because of weakness, poor shoulder positioning, changes in muscle tone, reduced movement, joint instability, or problems involving the muscles and soft tissues around the shoulder.  

The important point is that shoulder pain after stroke should not simply be accepted as part of recovery. Identifying the cause and protecting the shoulder during rehabilitation can help reduce discomfort and support better arm function. 

Why Does Shoulder Pain Happen After a Stroke? 

A stroke can affect the muscles and nervous-system control needed to keep the shoulder stable and coordinate arm movement. 

The shoulder is particularly vulnerable because it is a highly mobile joint. When the muscles supporting it become weak or movement becomes poorly controlled, the joint may not remain properly aligned during everyday activities. 

Several factors can contribute to post-stroke shoulder pain. 

1. Weakness in the Affected Arm 

After a stroke, the muscles of one side of the body may become weak or paralysed. 

This can include the muscles that help stabilise the shoulder. When these muscles cannot adequately support the arm, the weight of the arm can place stress on the shoulder joint. 

Weakness is one of the factors associated with shoulder subluxation and post-stroke shoulder pain. 

2. Shoulder Subluxation 

Shoulder subluxation occurs when the upper arm bone partially moves out of its normal alignment within the shoulder joint. 

In a weak arm, the muscles that normally help maintain shoulder alignment may not provide enough support. Gravity can then pull the arm downward, contributing to subluxation. 

A person may notice: 

• Pain around the shoulder 

• A feeling of heaviness in the arm 

• Difficulty moving the arm 

• Visible changes in shoulder position 

• Increased discomfort during transfers or movement 

Not every person with shoulder subluxation experiences pain, and shoulder pain can occur for other reasons as well. Proper assessment is therefore important. 

3. Poor Positioning 

How the affected arm is positioned in bed, a wheelchair, or a chair can influence comfort and shoulder protection. 

Allowing a weak arm to hang unsupported for prolonged periods may place unnecessary stress on the shoulder. 

Correct positioning can help protect the joint while the person is sitting, lying down, or participating in rehabilitation. 

4. Incorrect Handling of the Affected Arm 

One of the most important things caregivers need to understand is that the affected arm should not be pulled during transfers. 

For example, pulling the arm to help a person get out of bed or move into a chair can place stress on a vulnerable shoulder. 

Caregivers should learn safe handling techniques from the rehabilitation team.  

5. Spasticity and Changes in Muscle Tone 

Some stroke survivors develop spasticity, in which muscles become unusually stiff or overactive. 

Changes in muscle tone can alter how the shoulder and arm move and may contribute to pain or restricted movement. 

When stiffness develops around the shoulder, normal arm movements can become increasingly difficult. 

6. Reduced Shoulder Movement 

A person who cannot actively move the affected arm may gradually use the shoulder less. 

Reduced movement can contribute to stiffness and loss of range of motion. If the shoulder becomes increasingly difficult to move, everyday activities such as dressing and bathing can become more challenging. 

This is why appropriate movement and positioning are important components of stroke rehabilitation. 

7. Muscles and Soft-Tissue Problems 

Shoulder pain may also arise from problems involving muscles, tendons, ligaments, or other soft tissues around the joint. 

Because post-stroke shoulder pain can have several possible causes, simply treating the pain without understanding why it is occurring may not address the underlying problem. Clinical guidelines emphasise accurate assessment of the cause before deciding on management. 

 

What Does Post-Stroke Shoulder Pain Feel Like? 

The symptoms can vary considerably. 

Some people describe: 

• A dull or aching pain 

• Sharp pain during movement 

• Pain when lifting the arm 

• Discomfort while getting dressed 

• Pain during transfers 

• Stiffness around the shoulder 

• A feeling of heaviness 

• Pain that interferes with sleep 

For some people, the pain may be mild initially and become more noticeable as they begin using the affected arm more. 

Any new or worsening shoulder pain should be discussed with the treating rehabilitation team. 

How Is the Cause of Shoulder Pain Identified? 

There is no single test that explains every case of post-stroke shoulder pain. 

A rehabilitation professional may assess: 

• Shoulder position 

• Muscle strength 

• Muscle tone 

• Range of motion 

• Pain during different movements 

• Arm function 

• Joint stability 

• How the arm is positioned during sitting and lying 

• How the caregiver handles the affected arm 

• The person’s ability to perform daily activities 

The assessment helps determine whether the problem is related primarily to weakness, subluxation, stiffness, spasticity, soft-tissue problems, or a combination of factors. 

How Can Post-Stroke Shoulder Pain Be Managed? 

Treatment depends on the cause and severity of the pain. A personalised  stroke rehabilitation in chennai plan may include several approaches. 

1. Proper Shoulder Positioning 

Supporting the affected arm appropriately can reduce unnecessary stress on the shoulder. 

Depending on the person’s situation, therapists may recommend specific positioning in: 

• Bed 

• Wheelchair 

• Armchair 

• During transfers 

• During therapy 

Pillows, arm supports, lap trays, or other positioning devices may sometimes be used when appropriate. 

2. Physiotherapy 

Physiotherapy can help address weakness, reduced movement, poor coordination, balance, and functional limitations. 

Treatment may include appropriately selected: 

• Range-of-motion activities 

• Strengthening 

• Movement retraining 

• Task-specific exercises 

• Postural training 

• Arm-use activities 

The exercises should be adapted to the person’s shoulder stability and stage of recovery. 

Importantly, exercises should not simply be performed through pain. Some movements may be inappropriate when the shoulder is unstable or injured. 

3. Occupational Therapy 

Occupational therapy can help the person use the affected arm more safely during everyday activities. 

Instead of focusing only on isolated exercises, therapy may involve practising: 

• Dressing 

• Grooming 

• Eating 

• Reaching 

• Holding objects 

• Personal care 

The therapist can also teach the person and caregiver safer ways to complete these activities. 

4. Safe Handling During Transfers 

Caregivers often assist stroke survivors with moving between the bed, chair, wheelchair, and bathroom. 

The affected arm should be protected during these movements. Never pull on the weak arm to move or lift the person. 

Learning appropriate transfer techniques can reduce unnecessary strain on the shoulder. 

5. Appropriate Support Devices 

In some cases, a sling or another support device may be considered for shoulder subluxation or specific situations. 

However, the type and duration of support matter. Some slings can encourage prolonged flexed positioning and stiffness if used inappropriately. 

A physiotherapist or rehabilitation professional should determine whether a support device is suitable and teach the caregiver how to use it correctly. 

6. Managing Spasticity 

If increased muscle tone is contributing to shoulder problems, the rehabilitation team may incorporate strategies to manage it. 

Depending on the individual’s condition, treatment may involve therapeutic movement, positioning, stretching, or medical management. 

In selected cases, treatments such as botulinum toxin injections may be considered by the treating physician. 

7. Pain Management 

Pain management depends on its underlying cause. 

A doctor may recommend appropriate medication or other interventions when necessary. Rehabilitation may then focus on restoring comfortable movement and improving function. 

Pain relief and rehabilitation often work best when they are considered together rather than treating pain in isolation. 

Can Shoulder Pain Be Prevented After Stroke? 

It may not always be possible to prevent shoulder pain completely, but appropriate care can help reduce risk. 

Important precautions include: 

Support the affected arm 

Do not allow a weak arm to hang unsupported for prolonged periods. 

Handle the arm gently 

Avoid pulling or lifting a person by the affected arm. 

Use appropriate movement 

Shoulder exercises should be selected according to the person’s condition rather than performed forcefully. 

Pay attention to positioning 

The shoulder should be appropriately positioned while the person is in bed, sitting, or using a wheelchair. 

Begin rehabilitation appropriately 

Stroke rehabilitation can help address weakness, movement control, positioning, and functional limitations. Rehabilitation should begin as soon as medically appropriate and continue according to the person’s needs. (www.stroke.org) 

Why Shoulder Pain Can Affect Stroke Recovery 

Shoulder pain is more than a physical discomfort. 

When moving the arm hurts, a person may become reluctant to use it. This can reduce participation in therapy and everyday activities. 

Pain may also affect: 

• Dressing 

• Bathing 

• Sleeping 

• Transfers 

• Exercise 

• Walking with an assistive device 

• Arm rehabilitation 

• Overall confidence 

This is why managing shoulder pain can be an important part of maintaining progress during stroke rehabilitation. 

When Should You Seek Professional Help? 

Speak to the treating healthcare or rehabilitation team if a stroke survivor develops: 

• New shoulder pain 

• Increasing stiffness 

• Difficulty moving the affected arm 

• Swelling around the shoulder or arm 

• Significant pain during dressing or transfers 

• A noticeable change in shoulder position 

• Pain that interferes with sleep or rehabilitation 

Early assessment can help identify the cause and prevent inappropriate exercises or handling from making the problem worse. 

The Role of a Personalised Stroke Rehabilitation Programme 

Every stroke survivor has a different combination of weakness, muscle tone changes, coordination problems, and functional goals. 

Therefore, shoulder rehabilitation should not follow a fixed routine. 

A personalised programme may combine medical assessment, physiotherapy, occupational therapy, positioning, caregiver education, pain management, and functional training according to the individual’s needs. 

The goal is not simply to make the shoulder less painful. It is to help the person protect the joint, improve movement, use the affected arm safely, and regain greater independence in everyday activities. 

Conclusion 

Shoulder pain after stroke can develop for several reasons, including weakness, poor positioning, shoulder subluxation, spasticity, reduced movement, and musculoskeletal problems. Because the causes can overlap, identifying the underlying problem is an important first step. 

With appropriate assessment, careful handling, proper positioning, and targeted rehabilitation, many of the factors contributing to shoulder pain can be addressed. 

A painful shoulder should never be treated as “just another part of stroke recovery.” Protecting the shoulder today can make it easier for a stroke survivor to participate in rehabilitation tomorrow—and continue working towards greater independence.
