Elektroneurographie in der Neuro Praxis Düsseldorf

Introduction

This tutorial provides a step-by-step guide on conducting an electroneurography (ENG) examination, a method used to diagnose temporary or permanent numbness in limbs or the face, as well as to investigate the causes of gradual muscle weakness, muscle pain, and gait instability. Understanding this examination technique is crucial for healthcare professionals looking to assess nerve conductivity and identify potential nerve pathologies.

Step 1: Prepare the Patient

• Ensure the patient is comfortable and relaxed.
• Explain the procedure in simple terms to alleviate any anxiety.
• Ask the patient if they have any allergies or skin conditions that may affect the test.

Step 2: Identify the Nerves to be Examined

• Determine which nerves are relevant based on the patient’s symptoms.

Common areas include

• Arms
• Legs
• Face

Step 3: Position the Electrodes

• Place measurement electrodes at specific points along the nerve pathways being tested.
• Ensure proper placement to accurately capture nerve activity.
• Use adhesive or conductive gel to secure the electrodes in place.

Step 4: Stimulate the Nerves

Apply electrical stimulation along the nerve's pathway

• Use a stimulation electrode that is placed at a distance from the measurement electrode.
• Ensure stimulation is precisely timed to elicit a response without causing discomfort.
• Describe the sensation to the patient, informing them it may feel like a light tapping.

Step 5: Record the Responses

• Monitor and record the electrical responses from the nerves.
• Measure nerve conduction velocity and amplitude, which helps in diagnosing nerve damage or dysfunction.

Step 6: Analyze the Results

• Compare the recorded data against normal values for the specific nerves tested.
• Identify any abnormalities that indicate nerve damage or disease.

Conclusion

Electroneurography is a valuable diagnostic tool that helps identify nerve pathologies through careful examination of nerve conduction. By following these steps, practitioners can effectively assess nerve function and provide appropriate treatment recommendations. Next steps may involve further investigation or treatment based on the results of the electroneurography examination.
