Acromioclavicular (AC) Joint Sprain/Separation Self Test
If you are concerned with having an AC joint sprain or separation, here are two simple tests you can do at home to help find out!
Our favorite test that you can do on yourself at home is called the Spring Test. In order to perform this test, simply push down on your collarbone with your opposite hand. If pain is felt over your AC joint with this motion, you may have a sprain or separation present.
Another way to find out if you may have an AC joint issue is to observe what’s called a Step Off Deformity. In order to observe this, stick as many fingers as you can between your acromion and your clavicle.
- A presentation of only one finger width would be considered a Grade 1 Sprain
- A presentation of two finger widths would be considered a Grade 2 Sprain
- A presentation of more than this number of fingers, or if you observe a large bump on the top of your shoulder would be considered a Grade 3 Sprain
While self-testing is beneficial, preventative bracing and a comprehensive rehab program will also be necessary in order to safely return to play after this injury.
