Electrodiagnostics	Nerve conduction and electromyographic(EMG) studies are two of the electrodiagnostics that we perform.
Nerve Conductions Studies: In nerve conduction studies, an electrical signal is sent along a nerve to see how the nerve is functioning or if it is being 'pinched' at any particular place. This electric signal feels like an electric shock, but not a painful sensation. It tends to catch people off guard but does not hurt them. This study is used for making certain diagnoses such as: carpal tunnel syndrome; cubital tunnel syndrome; peripheral polyneuropathy; peroneal neuropathy; and many others.	How To Prepare For Your Electrodiagnostic Study: Do Not Apply Creams, Lotions, Or Powders to your skin on the day of your examination. If testing the upper extremities or neck, try to wear a looser fitting shirt; short-sleeved is preferred. If testing the lower extremities or lower back, bring a pair of comfortable shorts. Take all your medications as you normally would on the day of your examination. Don't worry about the examination. Most people find this examination much easier than they were expecting.
Electromyographic (EMG) Study: EMG studies are typically performed with the nerve conduction study. A small pin is inserted into various muscles to see if a nerve problem is causing a problem with the muscle that it goes to. It can sometimes identify diseases that affect muscle fibers as well. The pin sounds painful but most people don't find this to be the case. It is small and about the size of an accupuncture needle. Some diagnoses that EMG testing can be helpful include: Nerve axonopathy associated with an entrapment Cervical or lumbosacral radiculopathy Some myopathies (muscle diseases) Anterior Horn Cell Diseases (Lou Gehrig's Disease/ALS and Polio)
