The electromyogram is an exam used in the assessment of neuromuscular diseases. It evaluates the function of muscles, nerves and neuromuscular transmission (between the nerve and the muscle).
The exam is performed by a specialized physician. It consists of two main parts: neurography (studies the velocity of nerve conduction through the application of electrical stimuli to the nerve) and electomyography (evaluates the activity of the muscle at rest and during voluntary contraction through the introduction of small needles into selected muscles). You should perform the Electromyogram as quiet and relaxed as possible.
The doctor will then prepare the exam report.
