What should I do if I don t have the strength to do it, what is the matter with the fingers not bein

If you are tired of writing, the most effective way is to lift the brick flat, open the palm of the hand to support a brick (usually weighs 1 catty), arm straight, insist on 5 minutes, at the beginning can not hold on for so long, just practice step by step, so that you can not only exercise the wrist, but also exercise the fingers, but also exercise the shoulder joint. This is what my calligraphy teacher taught, and many of the ancients used calligraphy brushes to practice calligraphy in this way.

Do more wrist and finger strength training, and stick to it for a while.

Hand weakness is not only a problem of the hand, but also the strength of the upper limbs.

Buying a pair of dumbbells and mainly training your arms is better than just practicing your wrists or hand grip.

Work on the biceps and triceps, as well as the forearm.

You can buy another grip device, and you want that kind of rubber ring.

You can also train the deltoid muscle, which is the piece of meat on either side of the shoulder.

Buy arm strength equipment and exercise regularly.

Problem description: What is the reason why sometimes the fingers are not working? It's good again after a while.

Analysis: I've had an occasional situation like this, and after a day or two, it resolves on its own!

Go to the hospital to check if it is hyperthyroidism? Symptoms include nervousness, irritability, increased sweating, insomnia and fatigue, weakness, hair loss, weight loss, cracked nails, trembling hands, general weakness, inability to tolerate heat, and rapid heartbeat.

The most delicate part of the human body is the 19 small muscles of the hand, which is also the most precious part of the hand. With these 19 muscles, people can do very delicate and dexterous work. You must have seen a monkey eating an apple, and have you ever noticed that it must have eaten it with both hands?

This is because the monkey's five fingers are parallel to each other, and there is no function of palm and finger pairing, and one hand cannot hold things. And people can hold and hold it tightly because of the activity of these 19 small muscles. It allows the person's thumb to turn to the palm (called the opposite finger) and to the other fingers (called the opposite finger).

Palm and finger are the most important skills of human hands.

The 19 small muscles in the human hand are the key to being able to perform dexterous movements that animals can't. Of these, 4 are on the thumb, 4 on the little finger, 4 on the tendon, 4 on the dorsal surface between the metacarpal bones, and 3 on the metacarpal surface between the metacarpal bones. This is the structure of the internal muscles of our hands.

The hand is also the most abundant and sensitive part of human nerve sensation, and the nerve fibers are also the most concentrated. From the point of view of comparative research, the results of human genome testing show that rats and humans are roughly identical in genetic structure, with only 3% difference. However, there is a huge difference in the number of nerve fibers that the hands have.

Rats have 30,000 nerve fibers on their forepaws and 1 million on human hands, which is unmatched by any other animal. As a result, people have the most complex and special functions--- the connection and interaction between the hand and the brain.

Recently, Swedish experts have studied the relationship between finger activity and cerebral blood flow, and proved that when finger movement is simple, cerebral blood flow is about 10% higher than when the hand is not moving. But when the fingers make intricate, delicate movements, cerebral blood flow increases by more than 35%. The relative increase in cerebral blood flow is conducive to the agility of thinking.

This is a testament to the close relationship between the hand and the brain.

From the information displayed in the cerebral cortex of the human person, the hand occupies the largest area in the cerebral cortex, almost reaching 1 4 to 1 3. Therefore, the high flexibility of the hand is linked to the brain and is the result of a high degree of evolution that is unique to humans. It can be said that the hand is the second brain of a person.

1. Upper limb nerve entrapment: First, numbness and pain in the thumb, index and middle finger, often with a history of awakening at night, and the activity can be improved after waking up. In severe cases, it can be accompanied by atrophy of hand muscles, affecting the fine movements of the hand, because the median nerve is compressed in the wrist, the so-called "carpal tunnel syndrome"; The second is the numbness and pain of the ring and little finger, and there can also be a history of awakening at night, and in severe cases, it is accompanied by muscle atrophy, and the flexion force of the ring and little finger decreases, which affects the fine use.

This is because the nerve is entrapped in the elbow, the so-called "cubital tunnel syndrome".

2. Cervical spondylosis: The most common disease that causes hand numbness is cervical spondylosis, which is one of the most common diseases in middle-aged and elderly people. When people enter middle age, some organs tend to degenerate, when the cervical intervertebral disc degenerates, it often leads to cervical disc herniation or joint sudden hyperplasia or hypertrophy, these herniated cervical intervertebral discs or hypertrophic articular processes once compress the adjacent cervical nerve roots, cervical spondylosis occurs.

In addition to numbness and paresthesia in the fingers, cervical spondylosis is also accompanied by other symptoms, such as: pain in the neck and shoulders, radiating pain or mobility disorders in the upper limbs. It is not difficult to diagnose cervical spondylosis, as long as an X-ray is taken.

In addition, there is a simple way to check for cervical spondylosis, a person supports the head of the affected side, holds the upper limb of the affected side with one hand, abducts it by 90°, and pushes and pulls both hands in the opposite direction at the same time.

3. Stroke: Another common disease that causes hand numbness is stroke. "Hygiene Treasure Stroke" once said:

Mortals who are numb or insensitive to the first finger or the second finger will have a stroke within three years. "It must be prevented: it is advisable to live cautiously, eat sparingly, be far away, and be ambitious.

Although numbness of the fingers does not necessarily cause stroke, for middle-aged people over the age of 40, if they often have symptoms such as headache, dizziness, lightheadedness, numbness of limbs, and swollen tongue, and the patient usually has hypertension, hyperlipidemia, diabetes, cerebral arteriosclerosis and other diseases, they should pay more attention and be alert to the occurrence of stroke.

4. Menopausal syndrome: women who enter menopause sometimes have hand numbness, but it is not obvious, and with the end of menopause, hand numbness will disappear.

In short, the diagnosis of hand numbness symptoms requires reference to cervical spine radiograph, electromyography and other auxiliary examinations to make a clear conclusion. If the symptoms are obvious and there is obvious atrophy of the inner muscles of the hand, surgery should be taken in time to prevent the development of the disease, so as not to cause irreversible severe atrophy of the intrinsic muscles of the hand, resulting in serious dysfunction of the hand.

Is there anything else besides the lack of strength in the arm?
