Repetitive Nerve Stimulation Test

Repetitive Nerve Stimulation Test (RNST)

What is Repetitive Nerve Stimulation (RNS)?

RNS is an electrodiagnostic test which is used to assess the neuromuscular junction (NMJ).

When is Repetitive Nerve Stimulation advised ?

RNS is performed when you have muscular fatigue symptoms. It is commonly done to diagnose neuromuscular junction disorders such as Myasthenia Gravis (MG) or Lambert-Eaton Myasthenic Syndrome (LEMS).

How is the test performed ?

The response from your nerves in reaction to a repeated series of electrical stimuli will be recorded using a recording electrode which is placed on the tested muscle. You may be asked to exercise the tested muscle, for a few seconds to minutes, in between the series of electrical stimulation. Several nerves and muscles may be tested depending on your symptoms.

How to prepare for the test ?

Please stop medication (if already started for Myasthenia Gravis) 24 hours prior with your referring doctor's consent. Do wear loose- fitting clothing so that your hands, shoulders and neck are easily accessible for examination.

Electro Encephalo Gram (EEG)

Electroencephalography (EEG) is electrophysiological monitoring method to record electrical activity of the brain. EEG refers to the recording of the brain's spontaneous electrical activity over a period of time, as recorded from multiple electrodes placed on the scalp.

Video EEG

A video EEG (electroencephalograph) records what you are doing or experiencing on video tape while an EEG test records your brainwaves.

Nerve Conduction Study (NCS)

A Nerve conduction study is an electrical test that is used to determine the adequacy of the conduction of the nerve impulse as it courses down a nerve. This test is used to detect signs of nerve injury.

Electromyography (EMG)

Electromyography (EMG) measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle. The test is used to help detect neuromuscular abnormalities.

Repetitive Nerve Stimulation Test (RNST)

RNS is an electrodiagnostic test which is used to assess the neuromuscular junction (NMJ).

Visual Evoked Potentials (VEP)

A visual evoked potential is an evoked potential caused by a visual stimulus, such as an alternating checkerboard pattern on a computer screen. Responses are recorded from electrodes that are placed on the back of your head and are observed as a reading on an electroencephalogram (EEG).

Brainstem Auditory Evoked Response (BAER)

A brainstem auditory evoked response (BAER) test measures how your brain processes the sounds you hear. The BAER test records your brainwaves in response to clicks or other audio tones that are played for you. The test is also called a brainstem auditory evoked potentials (BAEP) or auditory brainstem response (ABR) test.

Botulinum Toxin Therapy

Botulinum toxin injection therapy (BOTOX therapy) is used to treat dystonia - neuromuscular disorder that produces involuntary muscle contractions, or spasm - that affects muscles that control movement in the eyes, neck, face, limbs, voice box, or the smooth muscle in the bladder. The goal of the therapy is to reduce muscle spasm and pain.
