Hand anesthesia four movements a day to solve nerve compression.

"My hand woke up at dawn. Is this oppressing blood vessels? " "After riding a motorcycle for a while, my hands are numb and I dare not ride a bike." "My hands are numb and the bowl is about to fall." "Do you really want to have an operation? I was too scared to sleep at night, and the result was even more numb! " The above is a common description of carpal tunnel syndrome patients, and it is also the most common reason for finger numbness.

Hand anesthesia-carpal tunnel syndrome

symptom

The situation of finger numbness gradually deteriorated from sporadic at the beginning to numbness all day, especially after a period of immobility (such as waking up after midnight) or the pressure of wrist flexion (such as holding the handlebar when riding a motorcycle or bicycle), and the symptoms were more obvious. If left untreated, it may lead to muscle atrophy at the root of the thumb, thus weakening the stretching and grip strength and seriously affecting daily life.

Favorable ethnic groups

People who use computers for a long time (so they are also called "mouse hands"), painters, housewives, mechanical maintenance workers, and people who like to knit by hand. Women during pregnancy and before and after menopause, patients with rheumatoid arthritis, diabetic patients and renal dialysis patients are also prone to this disease.

Prevention, prevention

1. Workers with heavy wrists should take a proper rest and exercise their hands to reduce the pressure on their wrists and increase the ductility and softness of their soft tissues.

Correct treatment

2. Find out the main causes of stress and improve it. Let the wrist be in a state of natural relaxation and avoid the wrist being in a bent position for a long time.

3. Use the wrist to fix the auxiliary wood (which can be cut by the occupational therapist with thermoplastic) or the commercially available auxiliary wood wrist guard (please refer to page 96) to protect the affected part and reduce the pressure.

4. Drug therapy: NSAID, muscle relaxant, vitamin B 1, B2, B6, B 12 preparations to assist nerve repair.

5, physical therapy: hyperthermia, wax therapy, ultrasound, electrotherapy.

6. When necessary, experienced doctors can accurately inject it locally under the transverse carpal ligament to reduce swelling and oppression.

7. If conservative treatment fails or there is obvious muscle atrophy, surgical treatment is recommended. Including traditional surgery or endoscopic minimally invasive surgery, the effect is quite good.

Carpal tunnel-an important nerve of the hand

Median nerve dominates the sensation of thumb, index finger, middle finger and part of ring finger, and the muscles from thumb to palm, and is an important nerve to control hand function. When it passes through the wrist, it will pass through the carpal tunnel surrounded by carpal bone and transverse carpal ligament.

This structure may be caused by physical changes (such as pregnant women or women before and after menopause), trauma, repeated stress (such as kneading dough, doing housework, washing clothes by hand), taking things for a long time and so on. , leading to soft tissue swelling, synovial sac inflammation, and benign tumors (such as tendon sheath cysts), narrowing the tunnel and further squeezing into the median nerve, leading to carpal tunnel syndrome. In addition to clinical symptoms and evaluation, nerve conduction examination can provide more accurate information, so that we can determine the location of nerve compression and understand the severity of the disease.

Hand numbness seems to be a problem, but there are actually many reasons. Stroke? Cervical nerve compression? Poor peripheral circulation? Diabetes causes peripheral neuropathy? Or the aforementioned cubital tunnel syndrome? Carpal tunnel syndrome? In order to make a correct judgment, it is necessary to analyze the concept and clinical symptoms of neuroanatomy, plus necessary examinations such as imaging medicine (X-ray, computed tomography, magnetic resonance photography, electromyography, nerve conduction velocity test, etc.). ) be more detailed before you can draw a conclusion.

Here, let me explain the numbness caused by the compression of the three main nerves of the wrist (median nerve, ulnar nerve and radial nerve). The three nerves that pass through the wrist all originate from the cervical vertebra. From the cervical spine to the fingers, as long as it is oppressed or injured, it may cause numbness. Because of the large amount of wrist activity, the pressure is naturally easy to concentrate here. If you want to know which nerve is compressed, you can infer the lesion by knowing their dominant area in the palm.

Symptoms of compression of three nerves in wrist

No matter which nerve is compressed, numbness is the same symptom. With the increase of oppression or improper handling, the degree of discomfort will also increase. If the nerves dominate the muscles, when the condition worsens, there will be symptoms of muscle atrophy and weakness.

Tinel sign can help us correctly diagnose which nerve is compressed if there is obvious numbness when tapping at the assumed compression point.

If the compression of median nerve, ulnar nerve and radial nerve occurs in the wrist, the common people and treatment methods are similar, and the treatment should first avoid excessive use and pressure. Avoid massage, which may aggravate the condition.

It is worth mentioning that the radial nerve is located in the superficial radial side of the wrist. A slight touch may cause numbness, especially if you don't press it, otherwise the radial nerve may be directly crushed. We have seen many injuries caused by improper massage, so we should not be careless.

Wrist tunnel reinforcement type 2

1. Stand with your feet shoulder width, hands flat in front, palms down.

2. Stand on tiptoe, lean forward slightly, palm down, and stretch your fingers forward until your arms are straight.

3. Then the fingertips are upturned, the palm roots are pressed down, and the five fingers are stretched to the maximum.

4. Then, the first finger is clenched and retracted, and at the same time, the elbow is close to the chest and the heel falls to the ground. Fingers and forearms need to be forced when moving, just like your hand reaches to the maximum, grab something hard and then pull it back hard; At the same time, lower the heel by pulling back.

5. Repeat the above actions 20 times for 1 time, and practice in the morning and evening.

Hint: This action comes from the formula in the Book of Changes. After simplification and modification, it is a good method to strengthen the strength and flexibility of forearm, wrist and finger in clinic. At the same time, the tiptoe action can improve the overall balance and coordination ability, and it is a preventive health care and conditioning action for upper limb diseases such as tennis elbow, golf elbow, wrist and finger tendinitis, trigger finger and mother's hand. However, if you are in the onset period of the above-mentioned diseases, you should seek medical attention first, and then practice step by step after the symptoms are relieved to reduce the recurrence of the diseases.
