G'day, my name's Fergus. I'm a physio. This is how I diagnose some injuries in my patients.
This is Andrew. He's hurt his right AC joint at footy on the weekend. We're just going to run through some of the tests for an AC joint.
First thing is that it's tender to push on. So, just on the end of his collarbone where it joins on to the shoulder blade. He has pain to push on it.
Next test I like to do is a "pull-apart" test. Andrew, just link your fingers and pull apart. That's usually pretty painful with an AC joint. The third test for an AC joint is horizontal flexion. Taking the arm across the body is usually pretty painful.
They're always painful with arm up above the head, as the collarbone rotates backwards as you lift your arm up. They're usually pretty sore to sleep on. They're sore to sleep on either side. So they're some of the tests I like for an AC joint.
