Do you sometimes feel like you're losing your balance when you're standing or walking? Do you feel dizzy or like you're about to fall? If so, today we're going to talk about a simple test that can help you find out why. This is called the Romberg Test. Don't worry, it's not a difficult test.
Do you know what the Romberg Test is?
Simply put, the Romberg Test is a short physical test that checks for balance issues, specifically those related to your sense of proprioception . Oh, now you're probably wondering what proprioception is. Let me explain that too. It's the ability to sense your body's movements, your position. To be precise, even with your eyes closed, you can sense where your hands are, where your feet are, that's what it's all about.
The Romberg Test mainly checks whether the dorsal column pathway , a part of your brain and spinal cord that controls proprioception, is working properly.
The test is done like this: You will be asked to stand with your legs together and your arms at your sides or folded across your chest. You will first have to keep your eyes open, then close them. Your doctor will watch you during this time and note any signs of swaying or loss of balance.
This test is named after Moritz Romberg, a 19th-century European neurologist who first introduced the method, especially to diagnose severe cases of tertiary/late syphilis.
How do we actually maintain balance in our body?
Balance is the ability to maintain a balanced body weight, stand upright, and move steadily. Think about it, it's because of this balance that we don't fall when we walk, run, or even just stand still.
Our bodies maintain this balance through a complex set of systems called sensorimotor control systems. These include:
- Sensory input from vision: Based on what we see, our brain can understand how we are and what the surrounding environment is like.
- Proprioception: As mentioned earlier, we sense the position and movement of our body parts.
- Vestibular system in the inner ear: This is what gives the brain information about our movement, balance, and spatial orientation. When you experience dizziness, something may be wrong with this system.
- This sensory input is properly collected and understood by the brain.
- Accordingly, providing motor output to the eyes and muscles.
We can experience injuries, certain illnesses, vision problems, certain medications, and as we age, one or more of these things can weaken. That's when balance problems arise.
The Romberg Test helps determine whether your balance problems are due to a problem with proprioception.
What is this proprioception?
Let's talk a little more about proprioception. This is our body's ability to sense its own movements and its position in space (the environment around us).
The dorsal column-medial lemniscus pathway (DCML) , or simply the dorsal column , is a sensory pathway in our central nervous system —that is, the brain and spinal cord. It is through this pathway that we perceive subtle sensations of touch, vibration, and position from nerves in our skin, muscles, and joints.
Whatever movement we make, sensory receptors in our skin, muscles, and joints send impulses to the brain through this dorsal column. This information, combined with visual input and information about balance and movement from the vestibular system in the inner ear, tells the brain where and how our bodies are.
The Romberg Test involves removing the aid of vision when the eyes are closed. This can be used to see how well proprioception is working to maintain balance. This can help identify the presence of a neurologic condition that affects proprioception.
When is the Romberg Test necessary?
Doctors usually perform this Romberg Test:
- For those who have balance problems, dizziness, and frequent falls.
- This is also done as part of routine neurological exams .
This test is very useful in diagnosing and assessing various neurological conditions. Here are a few examples:
- Parkinson's disease
- Friedreich's ataxia
- Vitamin B12 deficiency
- Tertiary/late syphilis
- Normal pressure hydrocephalus (NPH) in elderly people who fall frequently
- Wernicke's syndrome
- Ménière's disease
- Brown-Sequard syndrome
- Posterior cord syndrome
But remember, balance problems can also be caused by other conditions related to your vision and vestibular system.
Who performs the Romberg Test?
The Romberg Test can be performed safely by any healthcare provider who is familiar with it. However, because it is a neurological exam, it is most often performed by neurologists .
How exactly is the Romberg Test performed?
This is a physical exam. Your doctor will give you instructions and watch you as you do it. Here are the steps:
1. You will be told to take off your shoes and stand with your legs together.
2. They say to keep your arms down by your sides, or cross them across your chest.
3. First, you need to stand straight without moving for about 30 seconds with your eyes open . The doctor will check your body movements and balance.
4. Then, you should stand in the same position and close your eyes . You should stay like this for about 30 seconds or a minute. The doctor will again assess your movements and balance.
There are various modified versions of the Romberg Test. They are used to assess balance in different situations. Two examples are:
- Sharpened Romberg test (SRT): This is used to check for ataxia (impaired coordination) in people recovering from decompression sickness (e.g., a condition that occurs in divers). Unlike the regular Romberg test, this one places the feet in a line, with the heel of one foot touching the toes of the other.
- Single-legged Stance Test (SLST): This is used to assess postural stability in the elderly and those with Parkinson's disease . It involves testing how long the person can stand on one leg with their eyes open. The test is completed in one minute. Each leg is tested three times.
What to expect during the test?
The Romberg Test is a very quick and simple test. When you do this, no one will hold you or help you balance.
But don't worry! Your doctor or the person doing the test will be sitting next to you and watching you closely. If they see you about to fall, they will quickly catch you and keep you from falling. Also, the area around the test site has been cleared of any objects that could cause a fall.
Does this require any special preparation?
No. You don't need to do anything special before doing the Romberg Test.
Are there any risks with this test?
If this test is performed in a safe manner by a trained doctor or healthcare professional, there are no known risks or complications.
How long does it take to know the results of the test?
Once you've completed the test, the doctor can tell you whether your Romberg Test is positive or negative.
But remember one thing. The Romberg Test alone cannot tell you exactly what is causing your balance problem or what is wrong with your dorsal column. Your doctor will need to do further tests to determine the exact cause.
What does it mean to have a positive Romberg test?
A positive Romberg test is when you lose your balance after closing your eyes. That is, if your body sways a lot, if you put a leg forward in the direction you are about to fall, or if you actually fall.
If your Romberg test is positive, your doctor will order further tests to find out what is causing your dorsal column to not work properly. A positive Romberg test can be caused by a variety of medical conditions.
What does it mean when the Romberg test is negative?
A negative Romberg test is when you can remain stable without significant swaying during the test.
This means that symptoms related to your vestibular system or proprioception may not be directly related to balance problems, or may be due to another cause that cannot be identified by the Romberg test.
When should you see a doctor if you have a problem with your balance?
Balance problems can be dangerous and can lead to falls. If you have any of these symptoms, be sure to see a doctor:
- Unsteadiness
- Dizziness
- Lightheadedness - (Sinhala: Feeling lightheaded, feeling like losing consciousness)
- Blurred vision
- Losing your balance and falling
- Feeling disoriented
- Feeling as if the room is spinning, for a while
- Feeling as if you're moving when you know you're still
- Feeling as if you're falling
Let's learn a little about this: What is the Modified Romberg Balance Test?
This modified Romberg balance test is sometimes used by law enforcement officers to check for alcohol-related impairment, but it is not a field test approved by the National Highway Traffic Safety Administration (NHTSA) .
When doing this, the officer will tell you to keep your legs together, tilt your head back slightly, and close your eyes. Then, after 30 seconds, you will be asked to say "stop" whenever you feel like it.
Finally, take-home message:
Losing your balance and feeling dizzy can be a scary experience. If you feel unsteady or off balance while standing or walking, please see a doctor. They can perform tests like the Romberg Test to help you find the cause of your balance problems. Remember, a proper diagnosis is the first step to proper treatment.
