Being able to walk does not mean that the Achilles tendon has not ruptured; the main sign of an Achilles tendon rupture is a positive heel lift test, which means weakness in the pads. Of course in Achilles tendon rupture, you can still walk because the flounder muscle is intact. However, in Achilles tendon rupture, walking is limited, especially the strength of the heel lift is reduced, and walking up and down stairs is affected. Therefore, there is no definite correlation between Achilles tendon rupture and the ability to walk. This is usually done through a rigorous physical examination, such as a squeeze test of the gastrocnemius muscle. Then MRI pictures are taken to comprehensively diagnose and determine whether the Achilles tendon has ruptured.
