What is EMG – Electromyography

The electrical impulses in muscles at rest as well as during contraction are measured by an EMG (Electromyogram). Nerves provide electrical impulses to muscles in the body, which trigger the muscles to behave in predictable ways. Muscles behave abnormally as a result of nerve and muscle diseases. During an Electromyography scan, a very little pin is put into the muscle, allowing us to assess the state of your muscles.

What is NCV – Nerve Conduction Velocity?

NCV (Nerve Conduction Velocity) measurements are used to monitor the condition of your nerves. Mild electrical stimulation is applied straight to the skin covering the nerve. The second set of electrodes is placed on the skin’s surface to measure the reaction. That impulse generates a visual signal on a digital screen that, when evaluated, can reveal details regarding the nerve’s status.

Monitoring electrical impulses in muscles and nerves can assist in the diagnosis of disorders that affect muscle tissue or nerves (such as myopathy, muscular dystrophy, amyotrophic lateral sclerosis, or peripheral neuropathies). EMG and Nerve Conduction Velocity are performed in combination to get more comprehensive information.
The findings of EMG/NCV testing can be a significant tool for your specialist in determining numerous disorders that might impact your nerves and muscles, allowing them to better curate your treatment procedure.

Is It Painful to Undergo These Diagnostic Procedures?

Even though the beginning of the stimulation might stun you at first, it is not painful, and most individuals are comfortable during the test process. It might feel weird because the test may cause the fingers or toes to twitch.
