Imagine that you are closing your eyes. If I asked you where your right hand is, you would be able to tell me without opening your eyes, right? Or your body knows how to walk to the bed in the room without bumping into it, even if there is no light at night. How does this happen? The reason for this is that our body has a 'sixth sense' that we don't talk about much, but is very important. In this article, we will talk about this amazing ability, which is Proprioception.
Simply put, what is Proprioception?
Proprioception is your body's innate sense of its own position, movement, and posture. Simply put, it's like an 'inside-out GPS system' that helps your brain understand where your limbs are, how they're moving, and how fast they're moving, even without you seeing them with your eyes. It's a process that happens automatically, without us even thinking about it.
Another word related to this is Kinesthesia . That is, using this ability of Proprioception, we learn and improve our body movements. It's like learning to ride a bike. Even though it's hard at first, later we do those things without even thinking about it. That's what Kinesthesia is.
These two abilities are what allow us to do things from simple things like throwing a ball of paper in the trash and eating with a spoon, to complex things like playing sports and dancing.
Without this ability, our lives would be unimaginably different. We would have to watch every movement with our eyes.
Let's look at some examples from everyday life?
To understand this better, let's take a few examples from our lives. Some of these things happen automatically, while others are things we do habitually.
Things that happen spontaneously
- Walking on a gravel road: When you walk on a rocky road, you don't have to think about how your leg muscles tighten and loosen to adjust to each stone. Your body does it automatically to maintain your balance.
- If you scratch your nose: If you scratch your nose, your hand goes straight to your nose without looking at your hand or looking at your nose in a mirror. How does that happen? It's because of proprioception.
- When lifting a weight: When you lift something heavy, like a gas cylinder, your body automatically determines how much force is needed to keep it balanced without dropping it.
Things that are developed through training (Muscle Memory)
We also call these " muscle memory ." It's like muscles have a memory.
- Riding a bicycle: When riding a bicycle, you have to do many things at once, such as pedaling, controlling the handlebars, and maintaining balance. Once you get used to it, you do these things without even thinking about them.
- Playing a musical instrument: A skilled pianist can play a beautiful song without looking at the keys because those fingers are used to those movements.
- Playing sports: This ability is essential for everything from timing the bat to hitting the ball accurately when playing cricket, to the way a soccer player controls the ball.
What parts of our body help with this task?
This is a very complex process. Without you knowing it, a huge program is going on inside your body for this. These are the parts that mainly help in this.
| Body part | The work being done |
|---|---|
| Brain | Several parts of the brain (particularly the Cerebellum , Brainstem , and Sensory Cortex ) process this sensory information. The brain makes the final decisions, such as, "Okay, now the hand is here, the leg should be bent like this." |
| Sensors (Mechanoreceptors) | Tiny sensors in our skin, muscles, tendons, ligaments, and near our joints tell the brain whether our bodies are stretching, tightening, or vibrating. |
| Vestibular System | This system in our inner ear is the main part of our body that maintains balance. It sends signals to the brain when our head spins and our body moves from side to side. |
| Eyes | What we see with our eyes also helps us understand our location. But this ability works just as well without our eyes. That's why we can do some things even with our eyes closed. |
What are the symptoms of poor proprioception?
When this ability is impaired, it can be difficult to even perform daily tasks. At such times, symptoms such as these are seen.
- Balance problems: Frequent falling, loss of balance.
- Clumsiness: Constantly bumping into household items, tables, and chairs, and bumping into limbs.
- Dizziness: A feeling of spinning.
- Lack of spatial awareness: Lack of sense of space, may bump into doors.
- Lack of coordination of movements: The limbs feel as if they are not working in unison.
- Applying unnecessary force: Writing with the pen too hard or too lightly.
- Target avoidance: When reaching for something like a glass of water, it either misses the target or stops before it reaches the target.
Remember, as we age, our joints, muscles, and nervous system become weaker, so this ability to sense proprioception can naturally decrease. That's why balance problems are more common as we age.
What medical conditions affect this ability?
This ability to proprioception can be temporarily or permanently impaired due to certain accidents, illnesses, and other reasons.
| Reason | Description |
|---|---|
| Accidents and surgeries | Joint injuries (e.g., sprained ankle), joint replacement surgery ( arthroplasty ), traumatic brain injuries (TBIs ), and stroke . |
| Diseases of the nervous system | Multiple Sclerosis (MS) , Parkinson's disease , Ataxia (condition in which movement is not controlled), Peripheral neuropathy (damage to the nerves in the limbs). |
| Other situations | Alcoholism, Autism Spectrum Disorder (ASD) , Arthritis , Inner Ear Disease (e.g. Vertigo ). |
How does a doctor check this?
If you have these symptoms, a doctor can check your proprioception with a few simple tests.
- Romberg test: In this test, the doctor will ask you to stand up straight with your legs together and your arms at your sides. First, open your eyes, then close them for a few seconds. They will then observe if you sway or lose your balance.
- Finger-to-nose test: You will be asked to touch the doctor's finger with your finger, then touch your own nose. You may be asked to do this several times quickly.
- Walking in a straight line (Heel-to-toe test): You are asked to walk in a straight line, with the heel of one leg touching the toes of the other leg.
Simple tests like these can give you a rough idea of your condition.
Can this proprioception ability be improved?
The answer to this question is, yes, most of the time it is possible! Especially if your problem is caused by an accident or aging, this ability can be redeveloped through the right exercises.
It is very important to seek the advice of a physical therapist for this. They will prescribe specific exercises that are appropriate for your condition. For example:
- Standing on one leg.
- Balancing on a balance board.
- Close your eyes and do some simple exercises.
- Exercise methods such as yoga or Tai Chi.
However, if the problem is caused by something like permanent brain damage, it may be difficult to completely cure it with exercise. In such cases, an occupational therapist can help you find other ways to safely perform your daily tasks.
When we talk about our senses, we usually think only about the eyes, ears, nose, tongue, and skin. But this proprioception is also a very important sense that makes our lives easier and more enjoyable. If you also feel a change in your body's balance, movements, or discomfort, don't just ignore it and see your doctor and talk about it .
Take-Home Message
- Proprioception is our body's innate sense of its own position and movements, like a 'sixth sense'.
- While this automatically helps with things like walking, this ability needs to be developed through training for things like cycling and playing sports.
- If you are constantly falling, have poor balance, or bump into objects, these may be signs of a weakening of this ability.
- This ability can be affected by a variety of reasons, from something as simple as a sprained leg to neurological diseases like Parkinson's.
- If you have any problems with this, it is important to seek medical advice. Often, this ability can be restored through physical therapy exercises.
