Electromyography serves to differentiate between neurogenic and myogenic damage, whether it is a disease of the neuromuscular junction, and to localize it.
Electromyography is a technique that records the electrical activity of various electrophysiological characteristics of the muscle under quiet state and different degrees of random contraction, as well as the stimulation of peripheral nerves after concentric needle electrodes are inserted into the muscle.
EMG can assist in differentiating between neurogenic and myogenic damage. It can also be used in neuromuscular junction diseases, helping to localize lesions in the anterior horn cells of the spinal cord, nerve roots, nerve plexuses, peripheral nerves and neuromuscular junctions, and muscle fibers, among other effects.
It should be noted that it is recommended that the examination be conducted after meals to avoid hunger-induced hypoglycemia, dizziness and other discomforts; the patient’s entire body skin clean before the examination, wearing loose clothing, easy to expose the limbs for the operation; please follow the specifications of the doctor’s instructions.
