The test is commonly used to diagnose disorders affecting the neuromuscular junction, such as myasthenia gravis, and to investigate unexplained muscle weakness or fatigue.

Yes. RNS can be safely performed in both children and adults when clinically indicated.

RNS evaluates communication between nerves and muscles using repeated electrical stimulation, while EMG assesses the electrical activity of muscles and helps diagnose a broader range of neuromuscular disorders.

You may feel mild discomfort or a brief tingling sensation from the electrical stimulation, but the test is generally well tolerated.

Individuals experiencing unexplained muscle weakness, rapid muscle fatigue, drooping eyelids, double vision, or suspected neuromuscular junction disorders may be advised to undergo this examination.
