Why the Doctor Taps Our Knee?

Why the Doctor Taps Our Knee?

If you’re wondering why the doctor taps our knee, you’re not alone. This reflex is called the Patellar tendon reflex, and it protects our air passages. However, there’s more to this reflex than meets the eye. Read on to learn why the doctor taps our knee, as well as why the reflex is not a good idea for everyone. The best answer is likely something along the lines of nerve damage.

Patellar tendon reflex 

The tap on our knee stretches the tendon that attaches the patellar bone to the thigh muscle. When this tendon is sprained, a signal is sent from the spinal cord to the thigh muscle, which in turn triggers the knee-jerk reflex. This reflex is not painful, and it actually has important protective functions. But it’s not the only reason the doctor taps our knee. 

Reflex tests are performed to check the health of the connective tissues in our legs and knees. The tap is designed to test reflexes and can also detect problems with the nervous system. A lack of jerks during the test can indicate nerve damage. This test helps doctors diagnose a range of disorders by determining the source of pain. It also helps identify whether there are other reasons for knee pain or if the knee jerks. 

Mono-synaptic response 

A simple example of a mono-synaptic response is the knee-jerk reflex. A tap on the knee causes a stretch of a thigh muscle. This stretching then sends a signal from the sensory neuron in the thigh to a motor neuron in the spinal cord. This nerve then sends information from the knee to the leg muscle, causing the leg to kick. 

To determine the magnitude of the MSR, we used a technique that measures the time between a stimulus and a muscle contraction. We measured the time in milliseconds for each reflex. When comparing the duration of these two tests, we found that the mono-synaptic reflex produced the smallest response. The reaction time was approximately 20-40 ms. This result shows that knee taps can activate the L3-S1 nucleus and produce a corresponding muscle contraction. 

Sign of nerve damage 

A doctor taping our knee is a definite sign that we may have nerve damage. Nerves are made up of fibers, called axons, that connect your body to your brain. If any of the fibers or the tissues surrounding them are damaged, the signals will not reach your brain. This may result in tingling, burning, or total loss of sensation. There are two kinds of nerve damage: first and second degree. A first degree nerve injury is reversible and will recover within a few hours to a few weeks. A second degree injury is characterized by the loss of continuity of axons and will need surgery to correct the problem. 

Nerves in the thighs, arms, and legs are part of the nervous system. An injury to these nerves can result in muscle weakness, painful cramps, or uncontrollable twitching. Sensory nerve damage can result in difficulty in carrying objects, walking, and fastening buttons. If you notice any of these symptoms, it is time to seek medical attention. There is a good chance that you are suffering from peripheral neuropathy, which can affect your body and make you feel miserable. A medical team can help prevent further damage by providing you with proper care and support for the symptoms.
