Mouse hand symptoms

For those white-collar workers who often stare at the computer monitor, click the mouse with their right hand, and type on the keyboard with both hands to process various files, mouse hand can be said to be one of the more common occupational diseases. The occurrence of mouse hand is not only related to repetitive keystrokes, but also to the flexion and extension angle of the wrist. So what are the symptoms of mouse hand?

In fact, the symptoms of mouse hand are very obvious. In addition to feeling pain in the hand, you may even feel numbness in the hand. This pain will also spread to the shoulders and other parts, which will have a great impact on our life and work. So what are the symptoms of mouse hand?

What are the symptoms of mouse hand?

The so-called "mouse hand" is a popular term. In medical terms, it is called "repetitive stress injury." Generally speaking, normal wrist movement does not interfere with the median nerve. However, when operating a computer, since the keyboard and mouse are at a certain height, the wrist must be dorsiflexed at a certain angle. At this time, the wrist is in a forced position and cannot be stretched naturally. When the wrist joint is in a tense state for a long time, the median nerve in the carpal tunnel is compressed, blocking nerve conduction. Symptoms such as tingling, numbness and weakness will appear in both hands, and some joints may even produce slight noises when moving. This is followed by pain that gradually spreads toward your shoulder, making the simplest hand movements—opening a can, dialing a phone number, or threading a needle—difficult.

How to treat "mouse hand"

Patients with severe "mouse hand" must go to the hospital for surgical rehabilitation treatment. For general first-time patients or those who want to prevent the disease, the best way is to prescribe a healthy wrist prescription for yourself.

1. 55-72 cm: The height of the desk should be adjusted between 55 and 72 cm. In addition, to make typing easier, the keyboard height should be slightly lower than the height of the elbows when sitting, and directly in front of the body so that the elbows can be bent to 90 degrees.

2. 5-10 cm: To use the mouse comfortably, the desktop area supporting the lower arm should be 5-10 cm.

3. 5 to 10 cm: Another 5 to 10 cm, here it refers to the chair. Ideally, the distance between the chair and the edge of the table should be controlled at 5 to 10 cm, and the height of the chair should be adjustable. An anatomically correct seat and backrest should allow the body to move freely forward and sideways.

4. 2 hours: For healthy wrists, be sure to take a break and move your joints between every 2 hours of continuous work.

White-collar workers already know what the symptoms of mouse hand are. In fact, severe mouse hand requires patients to go to the hospital for medical treatment in time. In addition, if you want to prevent the formation of mouse hand, in addition to paying attention to the height of the desk, you should also pay attention to the distance between the chair and the edge of the table. In addition, if you work continuously with both hands for more than 2 hours, you should take a break immediately.
