Hi there. Abnormal NCV test results could be due to some
nerve damage or destruction, axonopathy or damage to long portion of the nerve cell, conduction block or demyelination. These could be seen in various conditions like diabetic neuropathy, uremia, traumatic injury to nerves, Guillain Barre Syndrome, any peripheral neuropathy, damage to spinal cord and disc herniation with nerve root compression. Consult your neurologist and wait for the MRI to reveal more about your existing pathology.
