Cumulative Trauma Disorder
Do you dread sitting at your desk all day? Does your body ache after work? If so, you are not alone. Every year thousands of computer users complain about pain in their necks, backs, legs, shoulders, elbows, and wrists. As more people use the computer for work, education and recreation-, the number of computer-related injuries increases. A broad name for the majority of these computer-related injuries is Cumulative Trauma Disorder (CTD) also known as Repetitive Stress Injury (RSI). According to the U.S. Bureau of Labor Statistics, Repetitive Stress Injuries account for more than half of all work-related injuries (Graps). You can prevent CTD or RSI if you know the symptoms and causes of these injuries, by making ergonomic purchases and maintaining the proper posture.
Computer injuries such as, CTD and RSI are commonly overlooked as minor injuries; when in actuality these injuries can be very severe and dramatic. Cumulative Trauma Disorder and Repetitive Stress Injuries are broad terms for all injuries resulting from placing too much repetitive stress on a joint - pulling on the tendons and muscles around the joint (Protecting Your Child…). The repetitive stress can be due to the lack of physical fitness, tension, stress, individual work habits, long hours, lack of breaks, bad ergonomics, and poor posture. The injuries can include but are not limited to the following conditions described on EGO's Ergonomic Manual, KidsHealth.org, and HealthTouch.com:
· Carpal Tunnel Syndrome - when the nerves running through your wrist into your fingers are trapped by the inflamed tendons around them. Symptoms include feeling "pins and needles", tingling, numbness and loss of sensation, pain or aching hands and arms, and eventually loss of coordination and grip strength.
· Cervical Radiculopathy - disk compression in the neck, often caused by repetitive cradling of the telephone on the shoulder.
· Tendonitis - an inflammation of a tendon. Repeated tensing of a tendon can cause inflammation. Eventually, the fiber of the tendon start separating, and can even break, leaving behind debris which induces more friction, more swelling, and more pain. Symptoms entail a dull ache over the wrist and forearm, some tenderness, and gets worse with the repetitive activity.
· Bursitis - the inflammation of a bursa. Bursas are small sacs located between bones and other moving structures such as, muscles, skin, or tendons. Bursas allow smooth gliding between these structures. When the sac is inflamed or irritated, swelling, pain and stiffness will occur. Bursitis and Tendonitis can affect the shoulder, elbow, wrist, finger, hip, knee, ankle, and feet.
· Ganglion cyst - swelling of a lump in the wrist resulting from a jelly-like substance leaking from a joint or tendon sheath.
· Reflex Sympathetic Dystrophy - rare, incurable condition characterized by dry, swollen hands and loss of muscle control; consistently painful.
One of the greatest risk factors leading to RSI is the restriction of circulation. When you extend your arms out to the side at shoulder level, the circulation is poor. When you use all the oxygen in the bloodstream, you begin to ache, loose strength and must put your arms to rest. This same thing happens during repetitive contractions like computing. During computing our tissues need all the oxygen and nutrients possible. When the bloodstream (circulation) is constricted from inflammation the tissues do not get the needed nutrients or remove the waste products (lactic acid and carbon dioxide) that build-up and cause more pain (Graps). To ensure you have good blood circulation become more ergonomic and improve your posture.
The improvements in the fields of science and technology are providing new ergonomic products for computer users. These products help computer users be more ergonomic-making equipment use less fatiguing and more comfortable. Ergonomic products prevent the discomfort resulting from operating the computer. Some of the most marketed ergonomic products include the mouse, split key...Read entire document
