A sudden fall, sporting collision or direct impact to the shoulder can sometimes result in an AC joint sprain. This common shoulder injury affects the acromioclavicular (AC) joint, which connects the collarbone (clavicle) to the highest point of the shoulder blade (acromion).

An AC joint sprain can cause pain, swelling, reduced shoulder movement and difficulty performing everyday activities such as lifting, reaching or sleeping comfortably. While some injuries improve with time and appropriate management, others may require professional assessment to understand the extent of the injury and identify suitable treatment options.

At Belconnen Physiotherapy Clinic in Canberra, our physiotherapists assess shoulder injuries and provide personalised care to help clients understand their condition and work towards improving movement, strength and function.

What is an AC Joint Sprain?

The AC joint is a small but important joint that helps coordinate movement between the arm, shoulder blade and collarbone. An AC joint sprain occurs when the ligaments supporting this joint are stretched or injured.

The severity of an AC joint sprain can vary depending on the amount of ligament damage. Some injuries involve mild irritation and stretching, while others may involve more significant disruption to the supporting structures around the joint.

Common causes of an AC joint sprain include:

• Falling directly onto the shoulder

• Contact sports injuries, such as football, rugby or hockey

• Cycling or motor vehicle accidents

• Heavy lifting or sudden force through the arm

What are the Symptoms of an AC Joint Sprain?

People with an AC joint sprain may experience a range of symptoms depending on the severity of their injury.

Common signs include:

• Pain at the top of the shoulder near the collarbone

• Tenderness when touching the AC joint

• Pain when lifting the arm overhead

• Discomfort when lying on the affected shoulder

• Reduced shoulder strength or movement

• Swelling or bruising after an injury

Some people may notice a visible bump or change in the shape of the AC joint. If you have experienced a shoulder injury and are unsure of the severity, a physiotherapy assessment can help provide guidance on appropriate management.

How is an AC Joint Sprain Diagnosed?

A physiotherapist will usually begin with a detailed assessment, including questions about how the injury occurred, your symptoms and how the shoulder is affecting your daily activities.

The assessment may include:

• Reviewing your injury history

• Checking shoulder movement and strength

• Assessing areas of tenderness

• Evaluating how your shoulder functions during specific movements

In some cases, further medical assessment or imaging may be recommended, depending on the nature of the injury and your individual circumstances.

Can Physiotherapy Help an AC Joint Sprain?

Physiotherapy for an AC joint sprain focuses on helping you understand your injury and supporting your return to comfortable movement and normal activities.

Your physiotherapy program may include:

Education and activity advice

Understanding what movements may aggravate your symptoms and how to gradually return to activities can be an important part of recovery.

Exercise rehabilitation

A physiotherapist may prescribe exercises designed to address factors such as:

• Shoulder mobility

• Strength of the shoulder and surrounding muscles

• Coordination and control of shoulder movement

• Gradual return to sport, work or recreational activities

Manual therapy and symptom management

Depending on your presentation, your physiotherapist may use hands-on techniques alongside exercise and education to assist with managing symptoms and improving movement.

How Long Does an AC Joint Sprain Take to Recover?

Recovery time for an AC joint sprain varies depending on factors such as:

• The severity of the injury

• Your activity requirements

• Your general health and fitness

• How your shoulder responds to treatment

Milder injuries may improve over several weeks, while more significant injuries can require a longer rehabilitation period. A physiotherapist can help you understand your expected recovery process based on your individual assessment.

Frequently Asked Questions About AC Joint Sprains

Can I exercise with an AC joint sprain?

It depends on the severity of your injury and the type of exercise. Gentle movement is often encouraged, but activities that significantly increase pain may need to be modified while your shoulder recovers. A physiotherapist can provide guidance on appropriate exercises and activity levels.

Should I see a physiotherapist for shoulder pain after a fall?

If shoulder pain continues after a fall, impact or sporting injury, it may be beneficial to seek an assessment. A physiotherapist can help determine the likely cause of your symptoms and provide advice on suitable next steps.

Do AC joint sprains require surgery?

Many AC joint sprains can be managed without surgery. However, treatment recommendations depend on the individual injury, symptoms and functional requirements. Your healthcare professional can discuss appropriate options based on your assessment.
