Maintaining static postures for prolonged periods of time and performing the same repetitive motions over and over can have adverse effects on the body, which is why the study of computer ergonomics is so important in today’s society. Computer-related injuries range from repetitive strain injuries, musculoskeletal disorder and work-related upper limb disorder to fatigue, migraine headaches and eye strain. Researchers say that it’s far easier to prevent injuries and stiff muscles from repetitive actions than to cure them.
One need only look at some recent statistics to learn the importance of computer ergonomics. Back injuries account for 33% of all workplace injuries, according to OSHA. Ten years ago, only heavy lifters reported back injuries, but today they are caused by people sitting at computers at work. Just three hours in front of a computer each day can increase health risks of tension headaches, low back pains, psychosocial stress, computer vision syndrome and occupational overuse syndrome, studies indicate.
As a result, computer workstations with ergonomic furniture have gained widespread popularity around the world. For example, there are special keyboards for typing designed to reduce muscle strain. Some keyboards split the keys up, with different elevated sections to increase the range of motion. Others are fixed at a certain elevated position to the user’s hands aren’t so bent while typing.
A special ergonomic chair with a tilt function helps workers stretch their backs and change postures throughout the day to allow different muscle groups a chance to relax. Adjustable computer workstation ergonomics gives individuals the ability to change their postures frequently by moving trash cans, document folders and mouse pads around. There are even laptop attachments, like a different type of mouse and monitor.
In addition to purchasing necessary computer ergonomics products, workers must be trained to spot health hazards like musculoskeletal disorders. Signs and symptoms may include painful joints, painful tingling or numbness in hands or feet, shooting pain in the arms or legs, swelling or inflammation, burning sensation, pain in wrists or shoulders, fingers or toes that turn white, back or neck pain, and stiffness. Many people suffer these problems due to repetitive motions and poor posture.
Ergonomic office chairs are becoming increasingly popular as more and more people spend long hours sitting at a desk. Find out more about the right chair for your body’s needs, from the Jobri kneeling chair to the Serta office chair, at the Ergonomic Chair site.
