Prevention and advice Carpal tunnel syndrome is a very common civilizational disease, mainly related to occupations in which hand movements are the main focus. With this disease there will be gradual numbness and burning pain in the hand, swelling of the wrist joint, inflexible hand movements, weakness and other symptoms, and at night the pain will increase, even making the patient wake up from the dream in pain. Keyboard, especially the mouse is our most common “carpal tunnel killer”. With the increasing number of people driving, the steering wheel has also become a major “carpal tunnel killer”. Other professions that use their hands frequently, such as musicians, teachers, editors and journalists, architects, assemblers, etc., are at risk of suffering from carpal tunnel syndrome. According to a survey from Singapore, women are the biggest victims of carpal tunnel syndrome, and its incidence is three times higher than that of men, with the majority of them between the ages of 30 and 60. This is because the female wrist canal is usually smaller than that of men, and the median nerve in the wrist is easily compressed. In addition, pregnant women, rheumatoid arthritis patients and people with diabetes, hypertension, thyroid dysfunction, the chance of suffering from carpal tunnel syndrome is also greater than the general population. In order to prevent “mouse hand”, usually should develop a good sitting posture, regardless of work or rest, should pay attention to the hand and wrist posture. Such as the computer keyboard should be facing you, if the side, may lead to excessive wrist bending tight; adjust the chair to the most comfortable height, sit down when the feet just flat on the ground; let the screen in the line of sight level or slightly lower. Keep the wrists straight, do not bend, but also do not overextend; elbow joints into 90 °; sitting back should be straight and close to the back of the chair, and do not cross the feet, so as not to affect blood circulation. In addition, attention should be paid to the rest of the hand. Once you have carpal tunnel syndrome, there is no need to be overly nervous. For patients with mild symptoms in the early stages, rest is most important, and if necessary, the wrist can be immobilized in a plaster splint to keep it straight. In severe cases, a carpal tunnel dissection is required for treatment. If it is left untreated for a long time, it may lead to nerve damage, blackening of the palm and muscle necrosis.
