The new version of the "Classification and Catalogue of Occupational Diseases" in China officially came into effect on August 1st. Among them, carpal tunnel syndrome, commonly known as "mouse hand", was officially included in the national statutory catalogue as an occupational disease for the first time. Data shows that the prevalence of "digital age work-related injuries" such as "mouse hands" among video terminal workers in China ranges from 12% to 15%. Does' mouse hand 'only come with a mouse? What are the typical symptoms? Are there any methods to prevent and alleviate it? Will regular massage cure it? How did the 'mouse hand' happen? There is a bony fibrous channel on the palmar side of the human wrist, called the carpal tunnel. Due to various reasons such as prolonged repeated wrist movements, the space in the carpal tunnel is occupied, which can cause an increase in pressure inside the tunnel, compression of the median nerve, and a series of symptoms such as pain. Its formation is closely related to long-term repetitive wrist movements or excessive local pressure, mainly manifested as wrist pain or finger numbness. Female wrist canals are naturally narrow, and hormonal changes (such as during pregnancy and menopause) may increase the risk of edema, so middle-aged women are more likely to suffer from "mouse hands". It is easy to confuse the symptoms of "mouse hand" and arm discomfort caused by cervical spondylosis, which delays treatment. In fact, there are clear differences in symptoms between them. Xiong Jian, Chief Physician of the Orthopedics Department at Peking University People's Hospital: Its positioning is very accurate. Generally speaking, there will be no discomfort in the neck, nor will there be a typical discharge like feeling from the neck to the upper arm to the forearm like in cervical spondylosis. The area it governs is half of the thumb, index finger, middle finger, and ring finger, so the most typical symptom is numbness in three and a half fingers. Sometimes when you stimulate it or compress it for a long time, it can appear like a discharge, feeling numb and numb to the hands. Will only office workers have a 'mouse hand'? Office workers who use computers and mobile phones for a long time are prone to developing "mouse hands", but there are actually many reasons and other professions that are also high-risk groups for "mouse hands". With the increasing number of drivers, the steering wheel has become a major "wrist canal killer", including assembly line workers, chefs, and others. Jiang Shan, director of the Department of Rehabilitation Medicine of the China-Japan Friendship Hospital: For example, if we play the piano or some domestic workers mop the floor or rub noodles for a long time, they can all cause "mouse hands". How to self-test the 'mouse hand'? In addition to the symptom of numbness in the fingers, there are also some signals in the mouse hand, including: the numbness symptoms of the fingers worsen at night or in the morning, and may be awakened by numbness; Decreased grip strength, making it easy for objects to fall off when held; In severe cases, there may be atrophy of the large fish border muscles, which means the base of the thumb becomes thinner. Xiong Jian, chief physician of the Department of Orthopedics at Peking University People's Hospital: I don't know if there is muscle atrophy. Just compare the two. If the muscles are round and full, and they are full when pressed, it means it is normal; If your hands are weak and there is numbness in a specific area, and the muscles in this area are flatter than those in that area, then there may be atrophy. The biggest misconception about "mouse hand" is that it's just a strain and doesn't matter. Many people think that carpal tunnel syndrome, also known as "mouse hand", is just a strain and doesn't need treatment. If it's uncomfortable, massage is enough. In fact, this is the biggest misconception. "Mouse hand" can cause irreversible damage to the nerves in the late stages of development. Xiong Jian, Chief Physician of the Orthopedics Department at Peking University People's Hospital: In the early stages of symptoms, such as mild numbness that does not last long and has a low frequency of attacks, we can treat them by stretching to relax. In addition, we can treat them with some wrist hot compress, including some physical therapy or oral medication, anti-inflammatory, anti-inflammatory, and nutritional/neurological drugs. If the progress is relatively fast, or even if there is muscle atrophy or hand weakness, we should go to the hospital for treatment. If the damage is severe, some patients may need surgery for treatment. Two golden actions teach you how to prevent "mouse hand". How to prevent "mouse hand"? Experts teach you two golden movements. Let's try them together ↓ Jiang Shan, director of the Rehabilitation Medicine Department of China-Japan Friendship Hospital: the first movement is the sliding of the tendons. We can do the flexion of the fingers, and then do a flexion, and then do a fist clenching movement. Our thumbs can be extended, and then we can clench our fists. Each movement can be done three to five times a day. The second action is the sliding of the median nerve, with the forearm extended and the palm facing upwards. Use this method to pull our median nerve, maintain it for 10 seconds, and slowly recover. Each action can be done about 5 times, and then done every day. It should be noted that during the pulling process, there should be no numbness or tingling sensation in the hand. (New Society)
