An EMG or electromyography is a diagnostic tool used to detect conditions and disorders affecting nerves and muscles. It provides information about the overall health of your muscles and nerves and shows how well they function. How EMG Works Your motor neurons produce signals that cause muscle contractions with electrical stimulation, and the EMG machine captures these signals and translates them into data, such as graphs and numerical values, to be interpreted later on. In order to capture ... [Read More]

What to Expect From an Electromyography Test
Electromyography (EMG) is a diagnostic test administered to people who may be experiencing muscle or nerve pain, including cramping, tingling, numbness, or weakness. An EMG involves needle electrodes inserted into the muscle being tested. The test is used to measure electrical activity in particular muscles when contracted. The test is also used to identify whether electrical activity is present when it shouldn’t be (that is, when the muscle is at rest). An EMG can identify whether the ... [Read More]
What Is an EMG?
Doctors use an electromyography (EMG) test to check a patient’s muscles and the health of the nerves that control them (the motor neurons). This diagnostic test is typically used for patients who may have damaged nerves or nerve dysfunction with regard to signal transmission to the muscles. The EMG test can accurately measure the speed of signal transmission between the nerves and the muscles. It is frequently used by doctors when checking for Guillain-Barré syndrome, carpal tunnel syndrome, ... [Read More]
