What are balance tests?Balance tests are a group of tests that check for balance disorders. A balance disorder is a condition that makes you feel unsteady on your feet and dizzy. Dizziness is a general term for different symptoms of imbalance.
Dizziness can include vertigo, a feeling that you or your surroundings are spinning, and lightheadedness, a feeling like you are going to faint. Balance disorders can be mild, or so severe that you may have trouble walking, climbing stairs, or doing other normal activities.
Different systems in your body need to work together for you to have good balance. The most important system is called the vestibular system. This system is located in your inner ear and includes special nerves and structures that help you keep your balance. Your vision and sense of touch are also essential for good balance. Problems with any of these systems can lead to a balance disorder.
Balance disorders can happen at any age, but are more common in older people. It's one of the main reasons that older adults tend to fall more often than younger people.
Other names: vestibular balance testing, vestibular testing.
What are they used for?Balance tests are used to find out if you have a problem with your balance, and if so, what is causing it. There are many causes of balance disorders. They include:
- Benign paroxysmal positional vertigo (BPPV). Your inner ear contains calcium crystals, which help control balance. BPPV happens when these crystals get shifted out of position. It can make you feel like the room is spinning or your surroundings are moving. BPPV is the most common cause of vertigo in adults.
- Meniere's disease. This disorder causes dizziness, bouts of hearing loss, and tinnitus (ringing in the ears).
- Vestibular neuritis. This refers to an inflammation inside the inner ear. It is usually caused by a virus. Symptoms include nausea and vertigo.
- Migraines. A migraine is a type of throbbing, severe headache. It is different than other types of headaches. It can cause nausea and dizziness.
- Head injury. You may get vertigo or other balance symptoms after a head injury.
- Medicine side effect. Dizziness can be a side effect of certain medicines.
Why do I need a balance test?You may need a balance test if you have symptoms of a balance disorder. Symptoms include:
- Feeling like you are in motion or spinning, even when standing still (vertigo)
- Loss of balance while walking
- Staggering while walking
- Ringing in the ears (tinnitus)
- Feeling like you are going to faint (lightheadedness) and/or a floating sensation
- Blurred vision or double vision
What happens during a balance test?Balance testing may be done by a primary health care provider or a specialist in disorders of the ear. These include:
- An audiologist, a health care provider who specializes in diagnosing, treating, and managing hearing loss.
- An otolaryngologist (ENT), a doctor specializing in treating diseases and conditions of the ears, nose, and throat.
Electronystagmography (ENG) and videonystagmography (VNG) tests. These tests record and measure your eye movements. Your vision system needs to work right for you to have good balance. During the test:
- You will sit in an exam chair in a dark room.
- You will be asked to look at and follow patterns of light on a screen.
- You will be asked to move into different positions as you watch this light pattern.
- Then warm and cool water or air will be put in each ear. This should cause the eyes to move in specific ways. If the eyes don't respond in these ways, it may mean there is damage to the nerves of the inner ear.
- You will sit in a computer-controlled, motorized chair.
- You will put on special goggles that will record your eye movements as the chair slowly moves back and forth and in a circle.
- You will stand barefoot on a platform, wearing a safety harness.
- There will be a landscape screen around you.
- The platform will move around to test your ability to remain standing on a moving surface.
- You will recline in a chair.
- You will put on earphones.
- Sensor pads will be attached to your neck, forehead, and under your eyes. These pads will record your muscle movements.
- Clicks and/or bursts of tones will be sent to your earphones.
- While the sound is playing, you'll be asked to lift your head or eyes for short periods of time.
- Your provider will move you quickly from sitting to lying down position and/or move your head in different positions.
- Your provider will check your eye movements to see if you have a false sense of motion or spinning.
You may also get one or more hearing tests, since many balance disorders are related to hearing problems.
Will I need to do anything to prepare for a balance test?You should wear loose, comfortable clothes. Depending on the test, you may need to make changes in your diet or avoid certain medicines for a day or two before your test. Your health care provider will let you know if there are any special instructions to follow.
Are there any risks to balance tests?Certain tests may make you feel dizzy or nauseous. But these feelings usually go away within a few minutes. You may want to make arrangements for someone to drive you home, in case the dizziness lasts for a longer period of time.
What do the results mean?If your results were not normal, your provider may order more tests and/or put you on a treatment plan. Depending on the cause of your balance disorder, your treatment may include:
- Medicine to treat an infection.
- Medicine to help control dizziness and nausea.
- Positioning procedure. If you were diagnosed with BPPV, your provider may perform a series of specialized movements of your head and chest. This can help reposition particles in your inner ear that have gotten out of place. The procedure is also known as the Epley maneuver, or canalith repositioning.
- Balance retraining therapy, also known as vestibular rehabilitation. A provider specializing in balance rehabilitation may design a program of exercises and other steps to improve your balance and prevent falls. This may include learning to use a cane or a walker.
- Diet and lifestyle changes. If you were diagnosed with Meniere's disease or migraine headaches, certain lifestyle changes may ease your symptoms. These can include increasing physical activity, avoiding certain foods, and quitting smoking. Ask your health care provider about which changes may be best for you.
- Surgery. If medicines or other treatments are not working, you may need surgery to correct a problem in your inner ear. The type of surgery will depend on the specific cause of your balance disorder.
