A neuro exam is just a physical (nothing painful). A nerve conduction test is a mild electrical current that measures nerve conduction(function). It is mildly uncomfortable and just kinda stings. A neuro exam is checking reflexes, strength, pupil reaction to light, balance, eye movement, facial/shoulder/tongue movement(cranial nerves), etc… Takes less than 10 minutes and is very valuable. Hope this helps. Dr. Shawn
