I was able to do a mock assessment on an athlete that had an Achilles tendon rupture. I performed the Thompson test on both legs and was able to see the real difference between a normal Achilles tendon and a ruptured one. Not only did I perform the test, but I was able to visually observe the difference in the muscular structure of the calves and ankle. The effected leg had less muscle definition than the normal leg. Also, I was able to palpate the difference of the structure of each. This particular tear was abnormal because the Achilles did not tear at the inferior portion of the tendon and roll up. It tore at the superior portion of the tendon and almost vanished. This will help me in the future because I will be aware of the fact that the tendon may not feel like a ball in the calf. I will also know what a true positive Thompson test looks like. This experience will also help me to understand what signs and symptoms to look for if I suspect a possible Achilles rupture.
