RNST - Repetitive Nerve Stimulation Test

Also Known As:

Jolly Test

RNS Test

Myasthenia Gravis Stimulation Test

Neuromuscular Junction Study

RNST evaluates neuromuscular junction function by applying repeated electrical stimulation to nerves. It is commonly used to diagnose conditions like myasthenia gravis. The test helps assess muscle response and detect abnormalities in nerve-muscle communication.

Includes 4 Test Parameters

Technique

A special nerve conduction study where a motor nerve is electrically stimulated several times per second.

Purpose

To evaluate the communication between nerves and muscles (neuromuscular junction).

Area Covered

Specific motor nerves and the corresponding muscle groups.

Key Clinical Point

The primary diagnostic test for Myasthenia Gravis, characterized by a "decremental" response in muscle strength.

Includes Test 5 Parameters

It is the standard test for diagnosing Myasthenia Gravis, a condition that causes muscle weakness.

A nerve is stimulated with several electrical pulses in a row to see if the muscle tires out too quickly.

It is when the muscle signal gets weaker with each pulse, which is a key sign of a neuromuscular junction disorder.

You must ask your doctor; often, medications like Mestinon are stopped for 12–24 hours to get an accurate result.

Nerves in the wrist, shoulder, or even the face (near the eye) are commonly tested depending on your symptoms.
