EMG/NCV in Pune
Book Now
EMG (Electromyogram) is employed as a diagnostic tool to identify neuromuscular conditions, evaluate lower back pain, study kinesiology, and investigate motor control disorders. Additionally, EMG signals serve as control inputs for prosthetic devices, including prosthetic hands, arms, and lower limbs.
A nerve conduction velocity test (NCV) is an electrical examination utilized to determine the efficacy of nerve impulse conduction along a nerve pathway. This assessment is valuable in identifying authentic nerve disorders (such as peripheral neuropathy and mononeuritis multiplex), as well as situations where nerve function is compromised due to mechanical compression injuries (like carpal tunnel syndrome and other compression neuropathies).
What is Electromyography (EMG)?
Nerves carry signals from the brain to the muscles and Nerves controls the action of the muscles by electrical signals, called impulses, that measures your nerve signalling and muscle response. Specifically, the needle EMG measures the electrical activity of your muscles. The aim of the EMG is to identify and determine the location, source of the problem.
Why is electromyography?
EMG can help your doctor determine the underlying cause of these symptoms.
- Tingling
- Numbness
- Muscle weakness
- Muscle pain or cramping
Paralysis - Involuntary muscle twitching (or tics)
- Muscle disorders, such as muscular dystrophy
- Radiculopathies
- Peripheral nerve disorders that affect the nerves outside the spinal cord, such as carpal tunnel syndrome
- Nerve disorders, such as amyotrophic lateral sclerosis
The NVC test helps your doctor differentiate between an injury to the nerve fibre 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. The importance of an NCV test is to look for nerve damage. During the test, a nerve is directly stimulated with an electrical current to see how it reacts. NCV tests can help diagnose a variety of muscular and neuromuscular conditions.
Who needs NCV test?
An NCV test can be used to diagnose a number of muscular and neuromuscular disorders, including:
- Guillain-Barre syndrome
- carpal tunnel syndrome
- Charcot-Marie-Tooth (CMT) disease
- herniated disk disease
- chronic inflammatory polyneuropathy and neuropathy
- sciatic nerve problems
- peripheral nerve injury
