Question 2: What is the harm of mouse hand, how to prevent it and how to improve it? How to prevent "mouse hand"
First of all, pay attention to maintaining a correct sitting posture at work, try to choose a suitable computer desk and support chair, keep the angle between the upper arm and the front of the body at 45 degrees when using the keyboard and mouse, and the distance between the body and the mouse is more suitable;
Second, try to choose a mouse pad with wrist protector to reduce the reaction caused by the release of the center of gravity of the palm and the pressure of direct contact with the computer desk;
Third, after working for about two hours, stop moving your arms, fingers and wrists and let them relax.
If you already have a mouse hand, don't worry. Can be cured by physical therapy. Patients themselves soak uncomfortable parts in hot water at home, and at the same time do hand activities in hot water, such as spinning two walnuts in their hands; If the shoulder is uncomfortable, you can use the horizontal bar to do pull-ups to relieve the tension of the shoulder muscles.
Question 3: What does mouse hand mean? Is it harmful to hold the mouse for a long time? The mouse hand must be a person who often uses the computer. When they are working or studying, their hands will inevitably deform after a long time. Holding the mouse for a long time is still very harmful. I suggest you adjust it properly, take a rest when you are tired, or buy a wristband online. After all, hands are important to everyone.
Question 4: What's the harm of using the mouse for a long time? Because long-term use may lead to wrist and hand joint damage. The way to avoid it is not to use the mouse, but this is impossible. The way to reduce the risk is to use engineering rats to reduce the damage, which can be counted as Viper, Kaiyang Star, Leibo V200 and other engineering rats!
Question 5: What are the hazards of occupational diseases (mouse hands) in the office? The higher the mouse position, the greater the damage to the wrist; The farther away the mouse is from its body, the greater the damage to its shoulders. Therefore, the mouse should be placed in a slightly lower position, which is equivalent to the height of the elbow when the upper arm is perpendicular to the ground when sitting. The position of the keyboard should be similar to this. Many computer desks don't have a special place to put the mouse, so it is self-evident that putting the mouse on the desktop for a long time will do harm to people. The distance between the mouse and the body will also be widened because the mouse is placed on the table, and the pressure in this respect will be borne by the shoulders and elbows for a long time, which is also one of the causes of neck-shoulder-wrist syndrome. When the angle between the upper arm and the front body is kept below 45 degrees, the distance between the body and the mouse is appropriate. If it is too far away, the forearm will lean forward with the upper arm and shoulders, causing continuous tension in joints and muscles. I hope it can be adopted.
Question 6: What harm and harm does the mouse opponent have? Theoretically, the higher the power consumption, the higher the probability of electromagnetic radiation.
Among keyboards, mice, screens and mainframes, it is obviously the mainframes and screens that consume more power.
So the mouse and keyboard basically have no radiation.
If the mouse position is appropriate, it can prevent mouse hands.
The mouse should be placed near the thigh in an upright position, so that your arms will droop almost naturally, so that your hands don't have to be raised as high as the monitor, and your shoulders and wrists will not be so sore.
It is better to lean forward 20-30 degrees at the bottom of the mouse, which is more natural and softer.
Question 7: If you play too many games and have a mouse hand, will this harm be great? Long-term use of computer keyboard and mouse may be linked to a disease called wrist joint syndrome, which may lead to pain and numbness of the index finger or middle finger and muscle weakness of the thumb, thus leading to nerve damage and muscle atrophy of the hand. The problem is that knocking on the keyboard or moving the mouse repeatedly every day leads to long-term, intensive, repetitive and excessive activity of the wrist joint, which leads to injury or oppression of peripheral nerves and blocks nerve conduction, thus causing sensory and motor disorders of the palm. Protect wrist health. Functional wrist pads can be used.
Question 8: What's the harm of using the mouse to deal with opponents? Computers are indispensable office equipment for modern office workers. However, clinically, it is found that more and more office workers who operate computers often exercise their wrists and fingers excessively for a long time, resulting in wrist numbness or wrist joint distortion, shoulder pain and other diseases, the most typical of which is the "mouse hand" called carpal tunnel syndrome.
People who work with a computer mouse or play computer games for 2 to 6 hours every day will have different degrees of wrist injury. If you feel numb in the palm of your hand when operating the computer, your index finger is prone to cramp when dragging the mouse, your wrist is swollen, and your hand movements are inflexible or even weak, then you may have been attacked by carpal tunnel syndrome.
Carpal tunnel is a fiber tunnel surrounded by transverse carpal ligament and carpal groove, which protects the median nerve of wrist. Generally, normal wrist movements will not interfere with the median nerve. However, when operating the computer, because the keyboard and mouse have a certain height, the wrist must be bent back at a certain angle, and then the wrist is naturally stretched by force. The wrist joint is in a state of tension for a long time, which compresses the median nerve in the carpal tunnel, so that the nerve conduction is blocked, resulting in obstacles in the feeling and movement of the palm, and then the above symptoms will appear. Women are the biggest victims of carpal tunnel syndrome, and its incidence rate is three times higher than that of men. This is because the carpal tunnel of women is usually smaller than that of men, and the median nerve of the wrist is easily compressed.
At present, there is no specific medicine for this kind of injury, so it is very important to actively prevent it. The key to prevention is to create a healthy working environment and correct operation, avoid excessive bending and tension of the wrist, and make the system suitable for the physiological and anatomical characteristics of the human body. It is found that when the wrist is kept at 0 degrees, the operator's wrist can be in a natural flat state, at which time the operator feels most comfortable and the incidence of wrist symptoms is the lowest. The height of the keyboard and the distance parallel to the human body should be adjusted to a comfortable position. Put a wooden board or mat between the desk and the mouse or keyboard to make it horizontal, so as to prevent wrist injury. At the same time, rest for about 1 0 minutes every operation, and it is best to shake your fingers and do * * * movements on your wrists and shoulders to relax and rest your hands properly.
Question 9: Is getting a mouse hand an occupational disease? 5 points Article 14 An employee shall be regarded as a work-related injury (occupational disease) under any of the following circumstances:
(1) Being injured by an accident during working hours and in the workplace;

Question 10: Can the computer mouse hand be cured? What treatment is the most effective? How to prevent and treat mouse hand
Vulnerable people: computer users, or repetitive workers who often do wrist parts. Women are more likely to have mouse hands than men.
Etiology: Among young people, mouse hand is an occupational disease caused by long-term use of computers. Because typing and moving the mouse repeatedly on the keyboard every day, the wrist joint repeatedly moves excessively, resulting in peripheral nerve injury or oppression, resulting in numbness, burning pain, wrist joint swelling, and inflexible or even weak hand movements. People who work with a computer mouse or play computer games for 2 to 6 hours every day will have different degrees of wrist injury.
Carpal tunnel is a fiber tunnel surrounded by transverse carpal ligament and carpal groove, which protects the median nerve of wrist. Generally, normal wrist movements will not interfere with the median nerve. However, when operating the computer, because the keyboard and mouse have a certain height, the wrist must be bent back at a certain angle, and then the wrist is naturally stretched by force. The wrist joint is in a state of tension for a long time, which compresses the median nerve in the carpal tunnel and blocks nerve conduction, thus causing the feeling and movement of the palm, which is called "carpal tunnel syndrome" in medicine. Hand surgeons believe that the mouse is more likely to cause hand injuries than the keyboard, because people always concentrate on mechanically moving one or two fingers repeatedly when using the mouse, and with this monotonous and slight activity, they will also strain the ligament of the wrist. Other occupations that may have similar effects, such as musicians, teachers, editors and journalists, architects, miners, etc., are all related to frequent use of hands. According to the research in Singapore, women are the biggest victims of carpal tunnel syndrome, and its incidence rate is three times higher than that of men, especially those aged 30 to 60. This is because the carpal tunnel of women is usually smaller than that of men, and the median nerve of the wrist is easily compressed. In addition, especially pregnant women and some patients with endocrine disorders, such as diabetes, thyroid dysfunction, rheumatism or rheumatoid arthritis, are more likely to cause carpal tunnel syndrome because of thickening of tendon synovium and narrowing of carpal tunnel lumen. Often using the computer will make the mouse hand more powerful.
Symptoms and manifestations
When operating the computer, the palm of your hand is numb, the index finger drags the mouse easily, the wrist joint is swollen, the hand movements are inflexible or even weak, and the three and a half fingers (thumb, food, middle finger and ring finger) of the affected limb have numbness and tingling, which is aggravated at night and sometimes suddenly wakes up with pain. Stinging and burning will radiate to the ends of fingers. When the hand temperature rises after work or the pain is aggravated by overwork, shaking your fingers can temporarily relieve the symptoms.
Treatment and prevention
This kind of injury needs rest, anti-inflammatory and analgesic drugs and physical therapy. If the symptoms cannot disappear, only by cutting the transverse carpal ligament in the carpal tunnel and relieving the compression of the median nerve can the symptoms be improved.
In order to avoid carpal tunnel syndrome, active prevention is very important. The key to prevention is to create a healthy working environment and correct operation, avoid excessive bending and tension of the wrist, and make the system suitable for the physiological and anatomical characteristics of the human body. It is found that when the wrist is kept at 0 degrees, the operator's wrist can be in a natural flat state, at which time the operator feels most comfortable and the incidence of wrist symptoms is the lowest. The height of the keyboard and the distance parallel to the human body should be adjusted to a comfortable position. Put a wooden board or mat between the desk and the mouse or keyboard to make it horizontal, so as to prevent wrist injury. At the same time, rest for about 1 0 minutes every operation, and it is best to shake your fingers and do * * * movements on your wrists and shoulders to relax and rest your hands properly.
Health tips:
1. Adjust the height of the keyboard and mouse on the computer desk, preferably lower than the height of the elbow when sitting, and at most the same height as the elbow.
2. Keep your wrist in a natural posture and try to get into the habit of moving the mouse with arm strength instead of wrist strength.
3. When buying a mouse, choose a model with large radian and wide contact surface, and don't choose a mouse that is too small for petty gain.
4. Try to use the mouse with both hands to reduce the time and pressure of using the mouse with one hand.
5. Try to change the input mode and replace the keyboard with a tablet.
6. Pay attention to health care in life, take a bath or soak chicken wrists and feet in warm water every day, keep blood vessels unobstructed, promote local blood circulation, insist on supplementing calcium, go outdoors to bask in the sun, do more exercise, and enhance local resistance of wrists. ...& gt& gt
