Assess Neuromuscular Junction Function: RNS evaluates how the neuromuscular junction responds to repeated nerve stimulation, providing insight into potential impairments in signal transmission between nerves and muscles.
Identify Neuromuscular Disorders: RNS can help diagnose neuromuscular disorders such as myasthenia gravis and Lambert-Eaton myasthenic syndrome.
Preparation: Patients may be asked to avoid certain medications and ensure their skin is clean and dry before the test.
Procedure: Electrodes are placed on the skin overlying the muscles to be tested. A series of electrical impulses are delivered to the nerves controlling these muscles at regular intervals.
Measurements: The test measures the electrical response of the muscles to the repetitive nerve stimulation. Changes in muscle response, particularly a decline in response with repeated stimulation, may indicate a neuromuscular junction disorder.
Results Interpretation: A healthcare professional interprets the results to assess neuromuscular junction function and identify any abnormalities.
Specialized Diagnosis: RNS provides detailed information about the neuromuscular junction, aiding in the diagnosis of specific neuromuscular disorders.
Non-invasive: The test is minimally invasive and generally well-tolerated by patients, with minimal discomfort.
Quick and Efficient: RNS can provide rapid results, allowing for timely diagnosis and treatment planning.
Myasthenia Gravis: RNS can help confirm the diagnosis of myasthenia gravis by showing a characteristic decline in muscle response with repeated stimulation.
Lambert-Eaton Myasthenic Syndrome: In this disorder, RNS may show a different pattern of muscle response, which can help differentiate it from myasthenia gravis.
