Tests and diagnosis

By Mayo Clinic Staff

During the physical exam, your doctor will inspect your lower leg for tenderness and swelling. In many cases, doctors can feel a gap in your tendon if a complete rupture has occurred.

The doctor may also ask you to kneel on a chair or lie on your stomach with your feet hanging over the end of the exam table. He or she may then squeeze your calf muscle to see if your foot will automatically flex. If it doesn't, you probably have ruptured your Achilles tendon.

If there's a question about the extent of your Achilles tendon injury — whether it's completely or only partially ruptured — your doctor may order a magnetic resonance imaging (MRI) scan. This painless procedure uses radio waves and a strong magnetic field to create a computerized image of the tissues of your body.
