Why does a medical doctor often tests the knee for reflexes? What is it really testing for ? Surely not that single area for a single purpose (reflex). What am I missing?
In: Biology
It’s actually just a straightforward test to see if the muscle and tendon and everything in between works fine, and for that area only. There are a lot of tests for various other areas too. I guess it gained popularity due to the simplicity and interesting effect, as it is fairly easy to do and looks cool on screen.
