Neurodiagnotic testing available:
Electroencephalogram (EEG) is performed to detect problems in the electrical activity of the brain. This painless procedure uses small, flat metal discs (electrodes) attached to the scalp in order to detect electrical activity in the brain. An EEG determines changes in brain activity that may be useful in diagnosing brain disorders, including epilepsy.
Electromyography (EMG) assesses the health of the muscles and the nerves that control them. During an EMG, a thin needle with an electrode is inserted through the skin into a muscle. The electrode records the electrical activity in the nerve and muscle and transmits it to a receiver that displays the EMG results on a printout or computer screen. An EMG can help diagnose disorders that affect the muscles, such as muscular dystrophy and nerve disorders.
Electronystagmogram (ENG) measures normal eye movement and involuntary rapid eye movements known as nystagmus. An ENG is performed to determine whether there is damage or a problem in the inner ear, brain, or nerves connecting them. During an ENG electrodes are attached to the face near the eyes to record eye movements. The movements are recorded on graph paper.
Nerve conduction testing (NCT) locates damage that has happened to the peripheral nervous system, which includes all the nerves that lead away from the brain and spinal cord and the smaller nerves that branch out from those nerves. Nerve conduction studies are often used to help find nerve disorders, such as carpal tunnel syndrome.
Summa’s neurodiagnostic services provide specialized diagnostic tests that assess anatomy or functioning of the brain, spinal cord, muscles, nerves and blood flow.
Individuals of any age can experience dizziness, vertigo and imbalance. These conditions are common among older adults and teenagers playing contact sports – like football and wrestling. Quite often, the source of this continued imbalance is within the inner ear.
Summa Health System’s Vestibular Diagnostic Testing Lab is one of the most comprehensive vestibular labs in Northeast Ohio. The lab offers the latest advancements in differential diagnostic technology.
Among the devices to test balance are:
Rotational chair that records eye movement as the patient spins Indications for rotary chair testing include:
- Bilateral canal paresis Inconclusive/equivocal ENG results
- Testing of special populations (pediatric, handicapped)
- Evaluation of vestibular compensation
- Ototoxicity management
- Videonystagmography and caloric testing record eye movements and is a definitive test for vertigo
Please answer the following questions by answering yes or no.
In the past month…
1. Have you felt dizzy (lightheaded, giddy, whirling, spinning, faint)?
2. Have you been imbalanced (nearly falling, veering, unstable on your feet, off balance)?
3. Has dizziness made you stop driving your car or change your driving habits?
4. Has imbalance caused you to hold on to things (furniture, walls etc.) to steady yourself?
5. Has dizziness or imbalance made you change how fast you get out of bed?
6. Have you had to become careful on how fast you move your head or what position you put it in
(looking up or down)?
In the past year…
7. Have you fallen?
8. Have you had to use a cane or other supportive device when walking?
9. Have you noticed any difficulty moving around as quickly as you used to?
10. Have your friends or family expressed concern about your sense of balance or mobility.
To have vestibular testing completed, you will need a physician referral. If you have answered yes to any of these questions, talk with your primary care physician to have a test ordered.
