Must be read by any computer chair user
If you spend hours on your computer sitting in a very good ergonomic chair, you may be sincerely concerned about the health of your lower back. However, if you still have back pain and discomfort, I highly recommend taking a moment to read these materials. You will be able to realize the true source of pain and tension. Understanding and understanding the real source will help you make the right decision.
In the past 30 years, low back pain syndrome has created an entire industry and it is growing. Drugs, chiropractic treatments, physiotherapy and massage therapies, numerous devices that eliminate or relieve pain and tension. Many of these therapies and equipment are well designed and very effective. Pain or tension disappears but only temporarily. Pain cannot be permanent forever because these treatments or devices are not at the heart of the problem. The truth is that the root of the problem is not the human body, and it has never been. The human body is only an effect. The root of the problem is how the body interacts with the computer. The problem is optimizing the interaction between the operator and the computer. However, if the "adjustment" is not completed correctly, the operator's organization always pays the price. In this section, we directly find the source of lower back pain to understand how to effectively understand or prevent it. Let's start to enter the lower back area.
Spinal and pelvic relationship
The spine of the human body comes from a large bone called the pelvis, which is well connected to it. The position of the pelvis plays a very important role in the shape and health of the entire spine. Here's how it works. During standing, the pelvis is in a vertically upwardly neutral position. The upright position of the pelvis places the spine in a tension-free state, and the healthy shape resembles the letter ' S. "The spine, pelvis and legs form a straight vertical line. This "S" shape of the spine also maintains the vertebrae in a neutral and healthy orientation relative to each other. This direction maintains minimal pressure on the disc.
Intervertebral pressure interpretation
The intervertebral disc is a forged ring between the vertebrae that acts as a shock absorber. But if the pressure is too high or the pressure is not uniform, they tend to bulge.
But where does the pressure that can bulge or damage the disc come from?
When the spine loses its natural curvature and remains stationary for an extended period of time, the pressure within the spinal disc increases. Laziness sitting on the wrong computer chair is an example of this shape. The intervertebral disc is very elastic and flexible. They can withstand tremendous pressure. However, the prolonged and uneven pressure within the disk due to the wrong posture of the upper body during sitting greatly increases the risk of disk expansion. This happens especially in the waist area. Protruding discs [outwardly protruding] often begin to press adjacent nerve roots. Stress on the nerve usually causes pain. Pain does not always occur in the lower back, but can also occur in other parts of the body. For example, if the protruding intervertebral disc is pressed against the sciatic nerve, a painful sensation occurs in the leg. It is worth repeating again:
Most low back pain and disorders originate from the wrongly supported spine sitting on a poorly designed or adjusted computer chair.
Approximately 90% of the raised discs appear on the lower back of the spell. The most common lumbar disc herniation disc is located between the lumbar vertebrae L4 and L5 and between the vertebrae L5 and S1, causing pain in the L5 nerve or S1 spinal nerve. Obviously, not only is lumbar disc herniation leading to low back pain, but in most cases, the problem of insufficient body is sitting on a computer chair that is not suitable for sitting for a long time, or without proper adjustment.
Waist support misunderstanding
Focusing on this part is very important. Traditional computer chairs with lumbar support may not be as ergonomic as most computer users and office chair industries believe.
The lower spine is often deformed when sitting on a traditional ergonomic chair with a lumbar support. In the last paragraph, we discussed the pelvis and its important role in maintaining proper alignment of the spine. In the case of an office chair with a lumbar support, the pelvis and its return movement are completely ignored. When we enter a fixed position, the unsupported pelvis is unstable and has a natural tendency to rotate. It does this because when we sit, the pelvis can't stand upright as we stand, we use muscles to stay straight. This rearward movement pulls the lower spine [waist area] toward the back of the chair. At the same time, the traditional lumbar support hump pushes the waist back in the opposite direction. These forces create tension between the spine in the lower back region. This is why so many people often experience low back pain or at least uneasiness when sitting on a computer chair with a lumbar support. This explains why in the Western world, low back pain has reached an unfavorable level. But there is a solution.
Healthy sitting solution
Like a typical ergonomic chair, instead of a lumbar support, there are two fully adjustable back supports. The lower one is to stabilize the pelvis and prevent it from moving naturally backwards as we said before. With this support, the pelvis is always in an upright position, as if we were standing. The vertical orientation of this pelvis maintains the natural "S" shape of the spine, virtually preventing the risk of low back pain and other related diseases. Another important part of this computer chair is that the upper [chest] supports it to stabilize the upper body, helping to maintain proper posture, including the chest, neck, and keeping the head in an upright position. It promotes proper breathing and effective condition reporting as round shoulders. The second article will detail these and various other benefits of using chest support.
Sitting on this truly ergonomic chair and maintaining this position does not require any effort. If you adjust this computer chair correctly, you can support the user very well. The user can stay healthy for a long time without tension and comfortable posture.
The chest support is adjusted to be placed 1 to 2 inches below the shoulder blade so that the computer user's arms, shoulders, and shoulder blades never touch the back of the chair during computer work. This gives computer users more freedom in weapons. motion. It also promotes correct, completely unstrained posture.
Thanks to these two independent and multi-adjustable back supports and true pressure-free seat cushions, this computer chair user can sit for hours without pain, tension, discomfort or tension. The end result is that a healthy body can always produce better results and efficiency in terms of productivity.
