EMG (also known as electromyography) is a test used to evaluate for neurologic conditions such as neuropathy, myasthenia gravis, myopathy and sciatica.  This test uses small electrical impulses to stimulate individual nerves.  By measuring the nerve’s response we can determine what and where the problem is.  The second part of the test involves using a thin needle to check several muscles.  This allows us to determine if there is an underlying muscle problem.  By using these two techniques we can accurately diagnose nerve and muscle conditions.  No special preparation is necessary for the test. 


Carotid ultrasound and transcranial doppler are two tests used to determine the amount of blood flow which is reaching the brain.  These studies evaluate for blockage usually from cholesterol which can cause stroke.  This study is performed with an ultrasound machine, much like the one used for prenatal ultrasounds.  No special preparation is necessary.


EEG (also known as electroencephalography) is a test used to evaluate the electrical activity of the brain.  This involves placing several wires on the head and recording the natural electrical impulses the brain is producing.  By examining these impulses we can determine if someone is prone to seizures.  This study is often used to assist in managing someone with epilepsy and in evaluating those with recurrent episodes of passing out.  Unlike the other tests we offer EEG does require some preparation. 


For routine EEG please wash your hair the night before or morning of your test. DO NOT use sprays or hair gels.  NO permanent hair accessories (i.e. weave, cornrows, toupees, extensions) Some exceptions may apply.  Bring a hat or scarf to wear home as you will have residual gel in your hair that will need to be shampooed out when you get home.  The test takes approximately 1.5 hrs.


For a sleep deprived EEG you may sleep prior to 1:00 am before the test.  Please stay awake after 1 AM.  No sugar, caffeine, soda, tea, coffee etc. before the test.
