What is there to prevent mouse hands?

In addition, Internet users repeatedly type and move the mouse on the keyboard every day, and the wrist joint is repeatedly and excessively active, resulting in peripheral nerve damage or compression, so that nerve conduction is blocked, resulting in the sensation and movement of the palm, causing the mouse hand.

When using the mouse, the fingers are frequently forced, and the nerves and muscles of the hand and related parts are damaged due to excessive fatigue, resulting in a series of phenomena such as numbness due to ischemia and hypoxia.

"Mouse hand" is commonly known as "carpal tunnel syndrome", which refers to the symptoms caused by the compression of the median nerve and the blood vessels entering the hand at the carpal tunnel, which mainly causes stiffness and pain in the index and middle fingers, numbness and weakness of the thumb muscles. Nowadays, more and more people are in contact with and use computers for a long time every day, most of these Internet users repeatedly type on the keyboard and move the mouse every day, and the wrist joints are paralyzed, swollen, painful and spasm of the wrist muscles or joints due to long-term intensive, repetitive and excessive activities, making this disease quickly become an increasingly common disease of modern civilization. Some people refer to this cluster of symptoms, which is different from traditional hand injuries, "mouse hands".

Broadly speaking, all upper limb (arm, wrist, palm, finger) discomfort caused by the use of a mouse should be called mouse hand or mouse injury, in addition to the above finger and hand symptoms, but also include shoulder and even neck discomfort, wrist and forearm fatigue and soreness, wrist stiffness, and palm soreness.

To prevent "mouse hand", the key is to try to avoid the upper limbs for a long time in a fixed, mechanical and frequently active working state, such as holding the mouse or typing, etc., every hour of work to get up and move the limbs, do some fists, finger pinching and other finger relaxation actions.

When using a computer, the height of the keyboard and mouse on the computer desk should be lower than the height of the elbow when sitting, which is conducive to reducing the damage to the lower back, neck muscles and tendon sheath of the hand when operating the computer. When using the mouse, do not hang the arm in the air to reduce the pressure on the wrist, and do not use the wrist force when moving the mouse but try to rely on the arm force to reduce the force on the wrist. Don't hit the keyboard and mouse buttons too hard, and use a moderate amount of force.

In addition, it is best to choose a mouse with a large arc, a wide contact surface, and a power dispersion.

The early symptoms of the mouse hand are relatively mild, such as cramps or occasional numbness in the palms of the hands when using the mouse only, and rest is needed at this time. If necessary, the wrist can be fixed with a wooden plank and straightened, and the symptoms can be improved by relaxing the pinched nerve and improving blood circulation.

Make a cue on your computer, say after 30 minutes and it will pop up and say to let your hand move.

After a while, exercise around the wrist to relieve fatigue

Don't overdo it?

Some scientists believe that the human hand is one of three vital organs that can have high intelligence. It can be said that the help of the human hand can be done, and the muscles of the human hand are very delicate and sensitive. With the popularity of computers in life, people have been exposed to computers and are using them more often.

Most people repeat the operation of moving the mouse every day and, therefore, have a "mouse hand".

In fact, mouse hands are divided into narrow and broad drug aspects. In a narrow sense, the mouse hand is repetitively pressed for injury. The clinical manifestations are compression of the nerves of the human body, as well as the blood vessels that enter the hand in the carpal tunnel, causing stiffness in the index and middle fingers, numbness and thumb muscles.

This allows nerve-muscular patients to cause a lot of stress leading to cumulative damage, so that in the hands of a typical mouse in the lateral skin of their carpal bones there is a subject of thickening and pigmentation. Broadly speaking, the mouse hand is not limited to the wrist, but exposes the entire upper part, wrist, palm, and finger discomfort, and the mouse is called a mouse or mouse harness. It mainly manifests itself as a absence of the shoulder or neck, such as fatigue in the forearms, stiffness of the wrist, palm palm.

How to prevent mouse hands? Details are as follows:

1. Performance relaxation: Employees use mice for a long time, but can relax their hands during breaks. After using mice for one hour to reduce stress on the nervous system and muscles of the wrist, the best time period is on the wrist.

2. Adjust the position of the mouse: the farther the mouse is placed, the greater the damage to the opponent, and the farther away the mouse is from the body, the greater the damage to the shoulder. Therefore, the position of the mouse is important and should be used in a slightly lower position. When the upper arm is vertical, it is the height of the elbow and the upper arm and the ground.

3. Use a large mouse: mainly responsible for the support of the hand, the flexion tendon of the hand, if the mouse is commonly used relative to the hand, the flexion tendon is often for a long time, and it is easy to throw tenosynovitis.

4. Use of a human bioengineered mouse: The market has launched a human bioengineered mouse, specifically using the frequency of the mouse, which is at an angle of 45 degrees with the desktop, right in the resting position of the forearm.

What is the method of mouse?

1. Reduce the time you spend using your mouse.

2. Pay attention to the comfort of the mouse.

If you work, you have to use a mouse and choose a mouse that conforms to the curvature of human physiology, a reasonable mouse design can reduce the burden on the hand. If the mouse hand is more severe, you must pay attention to the combination of work and rest. After a while, you should stand up and let your hands go straight and straight, which favors the flow of blood and thus relieves the stiffness.

3. Massage or heat for hands.

If there is a severe mouse hand, the pain can be relieved by massaging and taking medications. Or after work every day, put your hands in water at 45°C and let your hands increase, so you can speed up the blood circulation in your fingers and relieve pain.

It is to hold the mouse normally, and after a period of time, you can move your finger joints, or rest for a while.

In this process, it takes a long time to click the mouse, and you must pay attention to the combination of work and rest, and then pay attention to rest in the process of work.

Long-term use of the mouse can cause mouse hands, and we should move our wrists every hour when using the computer to relax our hands for a while.

1. The keyboard and mouse should be at the same height, lower than the height of the elbow when sitting. Moreover, it should not be too far away from the body, which is conducive to reducing the damage to the tendon sheath and wrist when operating the computer. 2. Choose a mouse with a large bend and a wide contact surface to disperse the force.

At the same time, use the mouse wrist pad to rest on your wrist. 3. Moderate force when hitting mouse and keyboard keys. Fourth, do not hang your arms in the air when using the mouse, so as to reduce the pressure on your wrists.

When moving the mouse, do not use wrist force but rely on arm force as much as possible to reduce the force on the wrist. Fifth, the maximum grip of the mouse of the upper limbs in a fixed posture for a long time, when using the mouse or typing with the keyboard, every 1 hour of work to get up and move the limbs, do some fists, finger pinching and other relaxed movements. If you often forget to take breaks, you can set an alarm or timer to remind yourself.

6. Do more hand exercises, such as stretching your fingers, to help improve hand coordination.

1. During work breaks, you can stretch out your arms and level with your shoulders, and then cross your left and right hands and clasp your fingers. Inhale, stretch your arms upward, and hold the position for 15 for 20 seconds. This can enhance the flexibility of the wrist, stretch the upper back and upper chest, and reduce shoulder plexus soreness.

It is important to note that after extending upwards, keep your arms close to your ears and your elbows straight.

When resting, you can try to do wrist exercises with your left hand outstretched with the palm facing inward and the fingers pointing downward. Press your right hand on the back of your left palm and apply pressure inward. Hold your breath for 30 seconds. Change to the right hand to do it. Repeat 2 3 times.

Extend your left hand with your palm facing outwards and fingers pointing up. Hold the four fingers of your left hand with your right hand and apply pressure backwards. Hold your breath for 30 seconds. Change to the right hand to do it. Repeat 2 3 times.

Choose an ergonomic mouse and keyboard with a better stress area. And as much as possible, put a wrist pad next to the mouse, put your hand on the wrist pad and then operate the mouse, so that the envy can relieve wrist fatigue.

Use keyboard shortcuts as much as possible to reduce the number of clicks on the mouse and allow your wrist to rest. So as to stay away from the "mouse hand" complications in terms of "quantity".

Stretch your arms flat, clench your fists, and rotate your fists inward with your arms as the axis, turning them continuously for 15 20 seconds. When you're done, do it again in the opposite direction. This relaxes the wrist muscles, allowing the wrist to remain flexible and the nerves in the arm to relax.

It is important to note that the shoulders and arms remain stable and immobile.

When using a computer, keep your forearms and elbows as close to your body as possible and as relaxed as possible so that you don't lean forward while using the mouse, and try not to let your arms hang in the air. Sitting in a computer chair, it is best to lean on the back cushion, with your feet flat on the ground, and remember not to stilt your legs.
