preface

Recently, I felt a little pain in my right wrist, so I learned about mouse hand, carpal tunnel syndrome and vertical mouse.

This problem is related to the health of programmers.

What is a mouse hand

Many of you have heard of mouse hand, but its scientific name is carpal tunnel syndrome. It refers to the “median nerve,” the sensory nerve in charge of fingers, which compresses when it passes through the carpal tunnel of the wrist, causing tingling and numbness on the side of the thumb, index finger, middle finger, and ring finger close to the middle finger.

Speaking is, it is a long time to maintain the wrist in the same action, such as typing, playing mobile phone, press the mouse, squeeze the wrist nerve, the final hand pain.

At first glance, it seems is a tailored for programmers, designers and so on the computer operators, actually say that is a bit wrong this “carpal tunnel syndrome, in fact, the emergence of the disease appeared much earlier than a programmer, just the spread of the programmer” carpal tunnel syndrome “known, because programmers here call it the” mouse hand “.

Early symptoms include pain and sometimes numbness in the fingers, palms and wrists; Elbow stiffness and discomfort; Clenched fist or palm up and down swing pain; The hand tingles especially at night. In addition, innocent friends, the wrist around the palm of calluses or a layer of pigment.

The mouse hand mentioned above is the narrow mouse hand in medicine,

Generalized mouse hand, because of excessive use of the mouse, will lead to the whole upper limb discomfort, especially the shoulder and neck pain, did not expect a small mouse, will be so serious!

Who is easy to be innocent? The first is you. Do you use the computer more than 8 hours a day? Can’t stop clicking the mouse? As early as 2000, an academic study in the Netherlands estimated that 23 percent of the working population had a “mouse hand” and that the age group was between 15 and 44. According to the latest report released by the China Internet Network Information Center (CNNIC) in January, China had 920 million Internet users as of December 2019, and self-employed workers accounted for 21.3 percent of the job structure. When you think about it, the number of people who use a computer every day… Very scary.

In addition, professional people who need to eat with their hands, such as pianists, journalists, badminton players and professional e-athletes, are vulnerable to being shot.

And then there are the moms. Think of housework, cooking with a knife (especially chopping), cooking with a shovel, the repetitive motions of day after day, and the squeeze on the wrist. Girls also have a narrower carpal tunnel physically than boys, so they are more likely to feel discomfort in their wrists. So trouble you please care more about mom, cherish the fruits of mom’s labor.

See, carpal tunnel syndrome isn’t just for programmers. Other athletes, musicians, housewives have it.

How to perceive palm fatigue

How to perceive palm fatigue? It’s simple. Generally speaking, you feel it yourself. If not, fingers point to the floor, the back of the two hands together, hold for 60 seconds, if the thumb, index finger, middle finger and ring finger outside, pain, numbness, burning and other feelings, it may be the symptoms of the mouse hand oh!

How to prevent mouse hand

Here’s how. This is dry stuff.

Prevention is better than cure for every ailment. So, this “carpal tunnel syndrome” how to prevent? In fact, it is nothing to move more palms and fingers…

Hand relaxation exercises, understand?

What, do not understand, give a picture:

A useful mouse-hand tip can be added to a mouse that programmers often use. Pay attention to the posture of using the mouse, keep a natural arc when holding the mouse, do not squeeze the Angle of the wrist, as shown in the figure:

Or switch to an ergonomic mouse, or use a wrist pad to relieve the pressure on the wrist’s central nervous system.

And if your hands have been sore for a while, don’t wait. The best thing to do is to see a doctor.
