Have you ever heard of carpal tunnel syndrome? You may find this term unfamiliar, but if you say “mouse hand” or “keyboard wrist”, I’m sure you’ll be familiar with it. That’s right, today we are going to introduce carpal tunnel syndrome which is commonly known as “mouse hand” and “keyboard wrist” in our daily life. As we type on the keyboard, our wrists form a certain angle with the keyboard, which increases the pressure in the carpal tunnel, and the lumen of the carpal tunnel becomes relatively narrow, causing a certain amount of pressure on the median nerve and the flexor tendons that pass through it, thus leading to dysfunction, which is the pathogenesis of Carpal Tunnel Syndrome. Of course, this problem does not only occur when you use a keyboard, but also in ordinary people who suffer from repetitive movements of the wrist over a long period of time. So how can you tell if you have carpal tunnel syndrome? Self-diagnosis: 1. A history of prolonged computer use, or a history of localized chronic injury to the wrist; 2. Restricted wrist activity, localized pain, aggravated by exertion; 3. Fingers, especially the index finger, middle finger, ring finger feel numb, obvious at night; 4. Such as when propped up on the table with the palm of the hand, the numbness of the hand will soon appear. Do not fret when you judge yourself to be suffering from this disease, in the next issue we have some great tips to help you solve the difficult carpal tunnel syndrome.
