The EMG records the electrical activity inside the muscle and the NCV test records how fast your nerves conduct. This test can help evaluate the origin of pain, weakness, or numbness and tingling caused by conditions such as nerve compression (example: Carpal Tunnel Syndrome), Peripheral Neuropathy, Sciatica, lower back or neck pathology.
This allows them to determine the best course of action for your treatment to see the best possible results which can help save you time and money!Įlectromyography and Nerve Conduction Velocity (EMG/NCV) determines if your symptoms may be caused by a problem with a nerve. These tests can be a great diagnostic tool for PTs and Physicians to help figure out exactly what is causing these issues. Since your muscles move when nerve signals from the brain tell them to get to work, Electromyography will measure how well your muscles are responding to those signals. When it’s not clear why you’re having problems with your wrist, back, legs, or other body part, that is when an EMG/NCV test can be very helpful. For many people, though, these types of pains are caused by an injured nerve, not an injured muscle. While it may be natural to have soreness or numbness in a muscle once in a while (you might strain a wrist muscle lifting something heavy for example) typically those aches/pains resolve within a few days or weeks. You might even have some tingling in these muscles as well. Let’s say that you have some sore or weak muscles and they have been feeling this way for a while and they don’t seem to be getting better.
