Ergonomic Positioning Explained for your Office Chairs
When seated in your office chair, proper positioning is a key element in keeping up good blood flow and body health. Movement is critical to good ergonomics. To keep the proper posture while constantly moving throughout the day takes some practice. It all starts with knowing how to properly position your back and legs.
Sit down in your current task office chair. Start by adjusting your backrest angle and the seat pan placing the torso and the upper legs at a 90 degrees or slightly more reclined position. This provides for good lower back support. Studies have found that the slightly reclined position is the most desired posture and a proper tilt mechanism, preferably with locking positions is critical to practicing good ergonomics.
Having your feet firmly on the floor is also very important. If your feet are not touching the floor, even with seat height adjustment, you will need to find a footrest or platform to rest your feet on. When viewing a picture of this posture on the human body, you will notice that 90 degrees is the overall effect. The arms are at an angle 90 degrees from the chest, the lower abdomen is 90 degrees from the lower leg and the upper leg is 90 degrees angled from the lower leg.
To keep the ergonomics in mind, placing your monitor at the proper height for viewing and making sure to keep the recommended manufacturer distance from the computer monitor is also important. Your eye level should be direct to the center of the monitor from the top and bottom and side to side to lessen neck twisting. The monitor should be adjusted accordingly to the seat height to get the right angles for comfort ability.
You probably spend a great deal of time typing or using a mouse device in your workstation. Relax your arms allowing them to hang down naturally from your shoulders. Next bring your forearms up so that they are positioned parallel with the ground. You want your wrist to be in a neutral position, very relaxed. Place your chair in front of your workstation desk and adjust the height of the seat so that your elbows are just at or above the keyboard height. You’ve done it with little effort, now practice makes perfect. Try to remember to keep the posture throughout the day and soon it will come naturally.
Taking the right position in your office chair is critical for long term body health and good ergonomics can help to prevent future back, neck and arm problems. Your spine is comprised of vertebrae like a stack of bones. At your lower back, this stack normally curves in. In between these vertebrae is a separate disk, and like an ice pack, it is strong on the outside and full of gel in the inside. If your vertebrae decide to stay in their normal position, the space in between the vertebrae and the disks are evenly filled with this ??el??
When leaning forward, the vertebrae pushes all of the gel to the rear of the back. This motion compresses the nerves that exit the spine to the central nervous system. In response, the nerve tightens up your back muscles, thinking it is supposed to contract the lower muscles in your back. With this continued movement, the muscles slowly pull the vertebrae further out of line while pushing the gel further back against the nerves.
This can become a vicious circle that once started, is hard to stop and can take quite some time to correct. Your back muscles, constantly being contracted are starting to ache and at the end of your work day it is hard to get comfortable in other seating. This same nerve that runs through the spine also runs down the leg to the feet and toes. Without treatment, the buttocks, legs and foot can also start to feel the pain. In the worst case scenario, the ??ce pack gel??can completely break open and you can be in for a long recovery.
Proper lumbar support is necessary for prevention of muscle and nervous system issues when seated at your workstation. Without this prevention, serious injuries can occur and workplace production can be completely put on hold. Proper lumbar support can be found in most good office chairs. Make sure when shopping for your chair that it has the back support needed for your work hours.
Carpal Tunnel is a common workplace concern due to the rising numbers of people suffering from carpal tunnel due to bad workplace ergonomics. Carpal tunnel affects the hands, arms, fingers and even the back of the sufferer and can cause serious problems, rendering the worker useless for even the simplest of tasks.
When constantly moving your fingers in a typing motion with your wrists bent, you are forcing your tendons to move in a pattern that they were not designed for. Eventually, the rubbing of the tendons will cause so much swelling that it will leave no room for the median nerve. When the median nerve becomes damaged by this constant compression you can lose sensation in your fingers and hands, starting with a tingle similar to numbness. This renders you incapable of completing even the simplest of office tasks.
Positioning your keyboard tray and mouse platform so that the elbows are at or above the keyboard height is important. Relaxing your arms so that they hang naturally from your shoulders will also help you to keep the proper position. Also make sure to keep your forearms parallel to the floor and your wrists in a neutral position. Make sure to always keep your feet on the floor, even if this requires a footrest.
With good ergonomic positioning and practicing proper techniques and keyboard/seat height placement, carpal tunnel syndrome can be avoided. Prevention of carpal tunnel in the office environment is as simple as keeping proper keyboard/seat height and remembering your postion throughout the day.
Ergonomic positioning is easy once you get used to keeping the correct posture. When practicing your office ergonomics, make sure to remember how critical it can be to keeping productive and healthy in the workplace.
