Electromyography(EMG) / Nerve Conduction Studies (NCS)
NCS and EMG tests are electrodiagnostic procedures that measure the electrical activity of muscles and nerves. NCS uses electrode stickers applied to the skin to measure the speed and strength of electrical signals between two points. During an EMG, a small needle electrode about the size of an acupuncture needle is inserted into the muscle and records the electrical activity of that muscle. Together, these tests can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission to help in the diagnosis of neuromuscular disease.
An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain. Special sensors (electrodes camera) are attached to your head and hooked by wires to a computer. The computer records your brain’s electrical activity on the screen or on paper as wavy lines. Certain conditions, such as seizures, can be seen by the changes in the normal pattern of the brain’s electrical activity.
A videonystagmography (VNG) is designed to determine the source of dizziness or balance disorders, it tests inner-ear and central motor functions. We test with the latest technology available, using infrared video cameras to record involuntary eye movements called nystagmus.
