computer sickness
Introduction
Introduction to computer diseases Computer disease is also called video display terminal syndrome. It is caused by the long time of using computer, the unscientific placement of computer and the poor environment of computer room. It is a kind of neurasthenia syndrome which is especially prominent in white-collar workers. Symptoms of computer disease mainly manifest as neurasthenia syndrome: dizziness, headache, fatigue, insomnia or nightmares, memory loss, depression and so on. basic knowledge The proportion of illness: 1% Susceptible people: no special people Mode of infection: non-infectious Complications: headache, insomnia, insomnia
Cause
Cause of computer disease
Physiological factors (60%):
Using the computer for too long, lack of rest, the body is too tired. Ignore the correct posture when using the computer, and keep the keyboard stroke for a long time, which will make the skeletal muscles of the shoulders stay in the "fixed" position. After a long time, the local blood circulation will not be long, the fresh blood can not flow in, and the metabolites It is difficult to discharge and naturally induces inflammation.
Environmental factors (30%):
The design of the computer desk is not good. For example, the position of the keyboard is too high or too low, the position of the mouse is wrong, the position of the computer is not scientific, and the environment of the computer room is not good.
Prevention
Computer disease prevention
1. Back Care: Office chairs are best designed with backrest, oil pressure and roller design. The chair has a backrest. If the seat is too deep, the back pad can be used to support the back, so that the back of the back maintains a normal curvature, reducing the pressure on the spine and muscles. The chair has a hydraulic design that adjusts the height of the seat so that the feet can be placed flat on the floor. The chair has a roller design that can be seated to adjust the angle of the body to twist, thereby reducing waist strain.
2. Mouse and keyboard: The height of the keyboard and mouse should be moderate. The height of the keyboard should be bent at about 80-100 degrees with the elbow. The height of the mouse should be the same as the keyboard. For those who are used to the right hand, the mouse should be placed on the right side of the keyboard. Long-term use of the keyboard and mouse, easy to induce tenosynovitis, then you can add a wrist pad in front of the keyboard or use a towel to make a wrist pad, so as to support the wrist and reduce the height of the wrist. The mouse position can also be made with a towel.
3. Computer screen: The screen should be adjusted to tilt upwards by about 15 degrees. After sitting, the first line of the screen is horizontal with the eyes. Do not face the window, at least 90 degrees to the window, reducing the refraction of sunlight. Add filters to the screen to reduce radiation and static. In order to balance the line of sight with the screen, avoid the head often hanging down and the neck repeating the action, you can add a folder , but note that the folder should be able to change position at will, to avoid the head twisting to one side for a long time, causing muscle overwork. Setting up the computer does not mean that the neck and shoulder pain is isolated. The bad habits of using a computer can cause pain problems. Develop a good habit, stay away from pain: use the computer to rest for 5 to 10 minutes every hour, do soft exercises or partial massage, and develop regular exercise habits, for the neck, upper limbs, lacing and strength training, to increase Softness and muscle strength.
Complication
Computer complication Complications, headache, insomnia, insomnia
1, computer body and mind disorders, is a "new disease." Due to long-term computer operation and programming, the central nervous system and autonomic nerves are dysfunctional, causing headache, insomnia, palpitations, excessive sweating, anorexia, nausea, and depression, slow thinking, irritability, and frequent fatigue.
2, writing amnesia, for long-term use of computers, especially those who use the pinyin input method, often find that after using the computer, when writing with a pen often can not remember the wording, experts believe that this It is suffering from "writing forgetting disease."
3, computer dermatitis, mainly seen in primary and secondary school students, manifested as eczema-like dermatitis of the extremities, with the most obvious upper limbs, when the holiday is on for a long time, the limbs are itching more.
4, computer addiction, mainly seen in children and adolescents. In particular, the use of computers is increasing, and some degree of satisfaction can be obtained from them; there are withdrawal symptoms such as depression, irritability, emotional irritability, and restlessness when not using a computer; I wanted to stop or reduce the use of computers. The number of times, but not successful; for the computer, you can sacrifice important social, learning, work and entertainment activities; despite one or the other problem, you can not give up using the computer; have the personality characteristics that want to show personal advantage.
5, memory decline, research shows that not only the elderly, but now many young people around the age of 20 are also facing the problem of memory loss. Experts point out that this is because the brain is flooded with too much secondary information and is saturated, the main culprit is the computer.
Symptom
Symptoms of computer disease Common symptoms Network relies on severe pain Finger joint pain, neck stiffness, cervical vertebrae hyperplasia, lumbosacral or lower back pain, carpal tunnel syndrome, neck pain, muscle atrophy, finger or arm thorn...
1. Neck and back: When the neck rotates, there is often a sound, which is easy to "frozen". Feel lumpy and tender. Local tingling. In severe cases, headaches, blurred vision, decreased attention, and paralysis of the upper limbs such as paralysis and pain may occur.
2. Tenosynovitis: long-term use of the keyboard or moving the mouse, the finger keeps sliding on the keyboard or typing, resulting in repeated repetition of the same action and friction for a long time, causing thickening and inflammation of the tendon sheath, which is tenosynovitis. The finger plate is pressed by the thick tendon sheath, which causes severe pain and local swelling.
3. Carpal Tunnel Syndrome: The design of the keyboard often allows the user to lift the wrist up to use it, but this part will make the carpal tunnel narrow, such as long-term, and the twitching of the hand is constantly sliding in the carpal tunnel, which is easy to cause Carpal tunnel syndrome, hand nerve lines and blood vessels are compressed, causing hand numbness and even muscle atrophy.
4. Lower limbs: Most people sit and work, but if they sit for too long, and the space at the bottom of the table is too narrow, the legs are difficult to straighten, so that the blood of the lower limbs does not circulate, and the feet are prone to paralysis. Long-term overlap of the two feet can cause the ligament of the clavicle to be too tired and cause strain.
Examine
Computer disease check
Check the items in accordance with the actual situation of the patient. Possible examination items: blood routine, spinal MRI, spinal hyperextension test, spinal mobility, spinal tenderness and snoring pain, spinal motion test, spinal curvature, fundus examination, electroencephalography, electrocardiogram.
Cervical CT examination has high practical value in cervical degenerative diseases and cervical spine injuries. High-resolution CT can clearly show the shape, structure, disc disease, ligament calcification and ligamentum flavum hypertrophy of the spine, and can clearly show the shape and structure of the cervical nerve root and spinal cord.
Diagnosis
Computer diagnosis and identification
Diagnosis can be based on medical history and symptoms. The above symptoms caused by other factors such as trauma, physical illness and the like are mutually distinguished. Can be distinguished from cervical spondylosis: cervical spondylosis, also known as cervical vertebra syndrome, is a general term for cervical osteoarthritis, proliferative cervical spondylitis, cervical nerve root syndrome, cervical disc herniation, is based on degenerative pathological changes Disease. Mainly due to long-term cervical vertebrae strain, bone hyperplasia, or disc herniation, ligament thickening, resulting in cervical spinal cord, nerve root or vertebral artery compression, a series of clinical syndromes of dysfunction. The manifestations of cervical disc degeneration and its secondary pathological changes, such as vertebral instability, loosening; nucleus protruding or prolapse; spur formation; ligament hypertrophy and secondary spinal stenosis, etc., stimulated or oppressed Adjacent nerve roots, spinal cord, vertebral artery and cervical sympathetic nerves cause a series of symptoms and signs.
