A member asked:

Why do doctors hit your knee when you get a physical?

A doctor has provided 1 answer

Reflexes: We are checking reflexes. The knee jerk is easy to cause. Hyperthyroidism can make the reflex much stronger and damage to nerves can make the reflex weaker or even cause it to disappear.
