Electromyography is a procedure in which the health condition of the muscles and their nerves is evaluated. The nerve cells are identified as the motor neurons, these motor neurons transmit the electrical signals, and these cause the muscles to relax and contract. Electromyography translates these signals into numbers or graphics, which are used by doctors to make a diagnosis. The doctor mostly orders EMG when the patient is displaying the symptoms of a nerve or muscle disorder. These symptoms include tingling, numbness, and even unexplained weakness in the limbs. EMG results can help the doctor diagnose muscle and nerve disorders and the disorders affecting the connection between the nerves and the muscles.
An EMG is a very low-risk diagnosis. However, the patient may feel sore in the area that was tested. The soreness may persist for a few days and can be reduced with an over-the-counter pain reliever, like ibuprofen.
In extremely rare cases, the patient may experience tingling, bruising, and swelling at the needle insertion sites. Make sure to inform the doctor if the swelling or pain becomes more hurtful.
The patient before having the Electromyography should follow these beforehand:
The entire process of the Electromyography takes about 30 to 60 minutes. During the procedure, the patient is required to lie on the table or a recliner. A needle is pierced through the skin into the muscle of the patient. The electrical activity is determined with the help of this needle. The activity is presented visually on an oscilloscope and can also be detected audibly by a speaker.
Since skeletal muscles are oftentimes large, several needle electrodes may need to be placed at various places to receive an informational EMG.
After induction of the electrode(s), the patient may be asked to engage the muscle.
The presence, size, and shape of the waveform produced on the oscilloscope provide data about the understanding of the muscle to respond to nervous stimulation. Each and every muscle fiber that contracts cause an action potential. The size of the muscle fiber affects the rate and the size of the action potential.
