Irritation of the longest nerve in the body - the sciatic nerve - is called sciatica. Here are a few conditions that an EMG can detect: Sciatica The needle electrodes record details, such as the speed of signal transmission and the strength of the transmitted signals.
Part of an EMG study also includes a nerve conduction study, for which electrode stickers are placed on the surface of the skin. The needle electrodes may be placed into any muscle to record its activity. Then, a recording of your muscular contractions as a response to stimulation will be sent to a computer. In order to capture the signals, needle electrodes will be inserted into your muscles. 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. It provides information about the overall health of your muscles and nerves and shows how well they function. doi:10.An EMG or electromyography is a diagnostic tool used to detect conditions and disorders affecting nerves and muscles.
