NCS or NCV

What is Nerve Conduction Velocity (NCV) Test?

The test which measures how fast an electrical impulse moves through your nerve is called a nerve conduction velocity (NCV) test, which is also known as nerve conduction study (NCS). If there is any nerve damage, it can be identified by NCV. It is done in pathology labs.

Outside of your brain and along your spinal cord, your peripheral nerves are located. To control your muscles and experience the senses, you get help from these nerves. Electric signals are sent more quickly and with greater strength by healthy nerves in comparison to damaged nerves. In differentiating between an injury to the nerve fibre and an injury to the myelin sheath, which is the protective covering surrounding the nerve, the doctor gets help from the NYC test. The difference between a nerve disorder and a condition where a nerve injury has affected the muscles can be found by your doctor with the help of it.

How does an NCV or NCS test work?

A nerve conduction velocity (NCV) test is used to assess nerve damage and dysfunction. Also known as a nerve conduction study, the procedure measures how quickly electrical signals move through your peripheral nerves.
Your peripheral nerves are located outside of your brain and along your spinal cord. These nerves help you control your muscles and experience the senses. Healthy nerves send electrical signals more quickly and with greater strength than damaged nerves.
The NVC test helps your doctor differentiate between an injury to the nerve fiber and an injury to the myelin sheath, the protective covering surrounding the nerve. It can also help your doctor tell the difference between a nerve disorder and a condition where a nerve injury has affected the muscles.

Who gets an NCV or NCS test?

An NCV or NCS test can be used to diagnose a number of muscular and neuromuscular disorders, including
If doctor suspects you have a pinched nerve, they may recommend an NCV or NCS test.
An electromyography (EMG) test is often performed alongside an NCV test. An EMG test records the electrical signals moving through your muscles. This helps detect the presence, location, and extent of any disease that may damage the nerves and muscles.
