EDX studies are often to diagnose disorders of the peripheral nervous system. These include disorders affecting the primary motor neuron (anterior horn cell), sensory neurons (dorsal root ganglia), nerve roots, brachial and lumbosacral plexuses, peripheral nerves, neuromuscular junctions, and muscles
Nerve Conduction Velocity Test (NCS)
A nerve conduction velocity test (NCS) measures how fast and electrical impulse moves through your nerve. During the test, your nerve is stimulated, usually with electrodes patches attached to your skin. You may feel like a small electrical shock and some discomfort. NCS can identify nerve damage
Is a very low-risk exam. The procedure involves the use of a very thin needle (acupuncture size) that may result in some discomfort, but it is usually well tolerated without any need of pain medication. EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission. We can use the data to determine if the problem is neuropathic or myopathic.
THE EXAMEN DAY
The day of the test patients can take your regular medications. Wear loose clothing.
Do not apply any lotions, creams or oils.
The discomfort, or mild pain experienced after the test is transient and most patients have no difficulty returning to their regular activities.
After the test we share the result with the patient.
