EMG - electromyography

Our neurology department has a new EMG diagnostic machine. EMG is used to examine the full spectrum of neuromuscular diseases, as well as peripheral nerve diseases. The speed of conduction of the impulse in the stimulated nerve and the magnitude of the electrical response to stimulation in the muscle or in another nerve site are measured. The most common diagnosis investigated is CTS - carpal tunnel syndrome (a compression syndrome that causes disability or damage to the median nerve - the nervus medianus in the carpal tunnel - of the wrist).
No special preparation is required before the examination. You can eat and drink normally and take your normal medications. There is no need to worry about the examination. If the doctor uses scanning skin electrodes for the examination, the method is absolutely painless. The needle electrode is inserted into the appropriate muscle, and inserting the needle electrode into the muscle by puncturing it causes almost no pain at all because the electrodes are very thin - thinner than ordinary injection needles.
The examination is ordered by a neurologist and a referral with a completed application form is required.

Evoked potentials

They are tests that monitor the current electrical activity of your brain. The examination is used when visual, auditory or spinal cord pathways are suspected to be affected. It is typically used to diagnose demyelinating diseases (such as multiple sclerosis), strokes and nerve damage. The examination is suggested by a neurologist or ophthalmologist. During the examination, sensing electrodes are attached to your head. The attachment is not painful. After verifying that all electrodes are in proper contact, you are given the task of watching the screen. At the same time, the doctor watches on a computer monitor how your brain reacts to visual stimuli. The examination of auditory evoked potentials (BAEP) is similar. However, instead of a screen, you will perceive audio signals from headphones. During a somatosensory examination, your doctor or nurse will attach electrodes to your wrists and ankles. The device will send weak electrical impulses to them. The duration of the examination is approximately 30-60 minutes.
