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
Testing the reflex can give you an idea of if there is any damage to the spinal cord or nervous system. Overactive or under active reflexes can also be a sign of other medical conditions
Hyperreflexia, or overactive reflexes can be a sign of hyperthyroidism, electrolyte imbalance, severe brain trauma, multiple sclerosis and preeclampsia
Hyporeflexia, or absent reflexes, can be a sign of ALS, Guillain-Barré syndrome, hypothyroidism, stroke
