Initially, no... but later [after "spinal shock" has worn off patients often have anywhere from slight to over-reactive reflexes. There's a great deal of good information on the 'net... Try the URL I've provided... : http://www.apparelyzed.com/
The instrument commonly used to demonstrate the knee-jerk reflex is called a reflex hammer. It is a small, handheld device typically made of rubber and metal, designed to strike tendons gently to elicit reflex responses. The most common reflex tested is the patellar reflex, which involves the knee-jerk response when the patellar tendon is tapped.
Patellar reflex is an involuntary, deep tendon and myotatic reflex
The patellar reflex is enhanced by voluntary muscle activity in the quadriceps. When you contract your quadriceps, it stretches the patellar tendon, causing a stronger reflex response when the knee is tapped.
The patellar reflex is a type of stretch reflex that involves tapping the patellar tendon to elicit a contraction of the quadriceps muscle and extension of the knee. This reflex helps to maintain balance and stability.
no
The statement "The patellar knee jerk reflex is controlled by the brain" is not correct. The patellar knee jerk reflex is actually a spinal reflex, meaning it does not involve the brain in its initial response.
the knee-jerk reflex
knee jerk aka patellar reflex is an example of a stretch reflex
The patellar tendon, just underneath the kneecap
they are located in the limbs, because the limbs are the effectors of the withdrawal reflex.

It may modify it.
