Nerve
conduction velocity (NCV) is a test prescribed to determine how well
and how fast nerves conduct electrical signals. Healthy nerves carry
the signals quickly and proficiently, whereas sick or injured ones
carry the signal slower and with less power. Doctors request these
tests to identify the signs of nerve injury or damage along with
evaluation for nerve and muscle disorders that can include symptoms
such as numbness, weakness, tingling pain, etc. NCV test also enable
doctors to see how the nerves working and locate where there is
pressure on it and how serious it is.
However,
the procedure for the test varies from individual to individual and
mainly depends on the condition of the patients. It’s a procedure
that doesn’t involve needles because it is completed by attaching
electrodes on the body of the patient over the nerves at different
areas. It helps in generating a precisely timed set of nerve
impulses.
Most of
the times, healthy nerves will have conduction velocity of about
50-60 m/sec, even though result can differ depending on patient and
type of nerve tested. Irregular results could be an indication of the
damaged or injured nerve, or it can be due to certain health
condition. Your physician will discuss everything in detail before
making any conclusion.
Preparing
for the procedure?
It is
essential for you to maintain regular body temperature prior and
during the exam because low body temperature can affect the nerve
conduction. On the other hand, you would not require fasting or
sedation for this procedure. However, you must inform your doctor
about medications that you might be taking. You also need to prevent
using oil and lotions on your skin for some days before the exam. You
must ask your doctors whatever questions you may have, as special
preparations may require depending on your condition.
However,
when scheduling a nerve conductivity test NYC,
it is vital to find an authentic place. A little research on the web
can help you find board certified physicians to schedule your exam.
