What Is an AC Joint Sprain?

The AC joint (acromioclavicular joint) sits at the top of the shoulder where the collarbone meets the shoulder blade. It helps transfer force through the shoulder during lifting, pushing and overhead movement.


An AC joint sprain occurs when the ligaments supporting this joint are stretched or torn, commonly after:

  • Falling onto the shoulder
  • Sporting collisions
  • Bike crashes
  • Tackles or contact sport
  • Heavy awkward impact



In milder cases the ligaments are strained. In more significant injuries there may be visible deformity or separation.

Common Symptoms of an AC Joint Sprain

You may notice:

  • Pain at the top of the shoulder
  • Tenderness over the AC joint
  • Pain lifting the arm
  • Pain reaching across the body
  • Pain during push-ups or bench press
  • Pain sleeping on the affected side
  • Swelling or bruising
  • Reduced strength
  • Clicking or instability sensations
  • Visible bump at the top of the shoulder in some cases

What Can Contribute to Ongoing Symptoms?

Persistent symptoms may be influenced by:

  • Residual ligament irritation
  • Poor shoulder blade control
  • Loss of shoulder strength
  • Guarding and stiffness
  • Returning to activity too quickly
  • Upper body loading errors
  • Neck or upper back compensation patterns

A proper assessment helps identify the key contributors.

Possible Causes of Top of Shoulder Pain

Pain at the top of the shoulder may relate to:

  • AC joint sprain
  • AC joint irritation from gym loading
  • Rotator cuff pain
  • Shoulder bursitis
  • Collarbone injury
  • Referred neck pain
  • Postural overload

An assessment can help determine the most likely cause and best treatment pathway.

How Physiotherapy Can Help AC Joint Sprain

Our physiotherapists combine hands-on treatment with targeted rehabilitation to help reduce pain now and restore long-term shoulder function.



You won’t simply be handed generic exercises and sent away. Treatment is based on the grade of injury, your symptoms and your goals.


Where appropriate, treatment may include:

  • Hands-on treatment to reduce pain and surrounding stiffness
  • Soft tissue treatment to neck, chest and upper shoulder muscles
  • Gentle mobility work
  • Taping or support strategies where appropriate
  • Advice for sleeping positions and daily tasks
  • Load management for work, gym or sport
  • Graduated return-to-training guidance


Many people seek treatment because they are struggling with pain lifting the arm, sleeping comfortably or returning to training.
