what the risks are nerve conduction test, ncv, nerve conduction velocity, ncv, the speed of conduction of impulses, a nerve,
nerve is stimulated, surface electrodes, patch-like electrodes, similar to those used, ecg, placed on the skin over the nerve at various locations, one electrode stimulates the nerve, a very mild electrical impulse, resulting electrical activity is recorded by the other electrodes, distance between electrodes, time it takes, electrical impulses to travel between electrodes, calculate the nerve conduction velocity, electromyography, the ncv test,
normal body temperature must be maintained, low body temperature slows nerve conduction, infants, children, test depends on child's age, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years,
impulse, an electric shock, depending on how strong the stimulus, feel it to varying degrees, uncomfortable you, should feel no pain once the test is finished, the nerve conduction test is followed by electromyography, emg, involves needles placed, muscle, contracting that muscle, uncomfortable, feel muscle soreness, site, the needles afterwards,
this test, diagnose nerve damage, destruction,
ncv is related, diameter, the nerve, normal degree of myelination, presence of a myelin sheath on the axon, the nerve, newborn infants have values, approximately half that of adults, adult values, reached by age 3,
most often, abnormal results, sort of neuropathy, nerve damage, destruction, demyelination, destruction, the myelin sheath, conduction block, impulse is blocked somewhere, along the nerve pathway, axonopathy, nerve axon, the associated diseases, alcoholic neuropathy, diabetic neuropathy, nerve effects of uremia, from kidney failure, traumatic injury to a nerve, guillain-barre syndrome, diphtheria, carpal tunnel syndrome, brachial plexopathy, charcot-marie-tooth disease, hereditary, chronic inflammatory polyneuropathy, common peroneal nerve dysfunction, distal median nerve dysfunction, femoral nerve dysfunction, friedreich's ataxia, general paresis, lambert-eaton syndrome, mononeuritis multiplex, primary amyloid, radial nerve dysfunction, sciatic nerve dysfunction, secondary systemic amyloid, sensorimotor polyneuropathy, tibial nerve dysfunction, ulnar nerve dysfunction, peripheral neuropathy, cause abnormal results, spinal cord, disc herniation, herniated nucleus pulposus, nerve root compression, essentially no risks,
a ncv test shows the condition, the best surviving nerve fibers, remain normal, a few fibers, unaffected by a disease process, a normal ncv test result, occur despite extensive nerve damage.
