The extensive use of high-tech products has become a major fashion in today’s society, which marks the fact that human society has entered an era of rapid development and high civilization.
However, in these high-tech products to bring people life, work convenience and pleasure, as well as spiritual enjoyment at the same time, excessive use or incorrect use of high-tech products can also lead to certain pathological changes in the tissue structure of the hand, causing harm to our hands, and ultimately the physiological function of the hand is affected.
The first injury: the mouse hand
The “mouse hand” is due to excessive use or improper use of the computer and lead to a series of hand clinical disorders of the general name or common name, also known as “mouse syndrome”. It is also known as “mouse syndrome”. Carpal tunnel syndrome”, “carpal tunnel syndrome”, “stenosing tenosynovitis”, “neck-shoulder-wrist syndrome”, “bursitis of the wrist”, etc., are not new diseases that were previously unknown. Excessive or inappropriate use of computers is only a new cause of these diseases, but it can also cause other parts of the body, such as cervical spondylosis, vision loss, and even psychiatric disorders.
Although the exact pathogenic law is still not clear, such as which diseases are directly caused by excessive or inappropriate use of computers, and which are aggravated by excessive or inappropriate use of computers, the clinical trend of similar disorders in the younger age, male, and the rapid increase in the incidence of people with related occupations can indicate that excessive or inappropriate use of computers and their There is indeed a very close relationship between excessive or inappropriate computer use and
Here are some tips.
First, for milder symptoms, the time spent operating the computer should be reduced, and the inflammatory edema of the synovial membrane in the carpal tunnel should be reduced by controlling the wrist joint activity so that the median nerve entrapment can be relieved, and intracarpal tunnel closure (such as steroid hormone plus appropriate amount of anesthetic drugs) can also be given. In a few cases where conservative treatment is not effective, surgical treatment can be chosen.
Scholars at home and abroad advocate that appropriate hand exercises, such as hand exercises, should be carried out before work to give the wrist and hand a good “warm-up” before the upcoming repetitive motion, which can reduce the incidence of carpal tunnel syndrome or related symptoms.
Third, according to their own hand size, shape, finger length and other physiological characteristics, choose the right type of keyboard, mouse, or add a hand pad can help alleviate the stress on the hand, wrist, to reduce the related injuries.
The second injury: cell phone hands
The most common hand disorder caused by excessive use of cell phones is tenosynovitis. This type of condition occurs mainly in teenagers.
In busy streets or large shopping malls, you can often see fashionable young people holding cell phones and sending frequent text messages. Under physiological conditions, the flexor and extensor tendons slide repeatedly, transmitting the power generated by muscle contraction to the joints and producing the flexion and extension of the fingers to meet the needs of hand function.
If the phone is often used repeatedly and for a long time, the friction or wear between the flexor-extensor tendon and the tendon sheath is too much and too frequent, leading to the occurrence of sterile inflammation, edema and thickening of the tendon, thickening of the tendon sheath wall, producing local pain, tenderness and swelling, as well as the finger activity when popping or suddenly strangulation in a certain position can not move. The most common site is the thumb or the radiodorsal aspect of the wrist joint.
I. If the above symptoms are found, the diagnosis should be confirmed at the relevant medical institution. Severe symptoms may be treated with drug closure, and individual patients may require surgery.
Second, to minimize the use of cell phones, change the way of use, such as try to avoid one-handed operation of cell phones, you can use two-handed operation, appropriate to disperse the stress on the fingers.
Third, choose a slightly larger model of cell phone, so that the hand can get more support, reduce the stress on the hand, so that the hand is less damaged.
Fourth, because the use of cell phones need to finger joints constantly in a particular direction to adjust the position, long-term, the stability of the joint structure will cause chronic damage, not only cause changes in joint stability, and even cause serious joint pain. At this point, the joint needs to rest and brake, otherwise it will cause irreversible consequences.
Warm up your hands before using them
Dr. Houshang Seradge, a leading orthopedic and hand surgeon at the Oklahoma Center for Orthopedic and Reconstructive Surgery, invented a simple method for preventing and treating strain disorders of the hand and wrist, which has been widely disseminated in Oklahoma and neighboring states with good results and praise.
Step 1: Both upper limbs are placed loosely on either side of the torso with the body upright.
Step 2: The right upper limb is extended straight forward to the level of the shoulder joint, with the palm of the hand up and the fingers apart pointing to the ground.
Step 3: Move the fingers and wrists upward while gradually clenching the fist and flexing the wrist so that the fist points in the direction of the exerciser.
Step 4: Bend the elbow joint so that the fist is pointing toward the shoulder.
Step 5: Rotate the upper body outward, still maintaining the bent elbow and fist position, and gradually turn the head towards the fist.
Step 6: Straighten the elbow joint and fingers in turn, dorsally extend the wrist joint so that the fingers point to the ground, and slowly turn the head to the opposite shoulder.
Repeat steps 1 to 6 above the left upper limb.
Step 7: Raise both upper arms to shoulder level, flex the elbows so that both wrists are palmarly flexed and pressed against each other with the backs of the hands, and point the fingers straight to the ground.
Step 8: Turn your hands overhead, wrists dorsally extended, palms and fingers close together, palms and shoulders back.
Step 9: With palms and fingers still close together, place hands above the head.
Step 10: Gradually move the hands to the back of the head, with the shoulder joints moving backwards at the same time.
Step 11: Straighten both upper limbs outward at shoulder level, make a fist and flex the wrist joint.
Step 12: Gradually lower both upper extremities to the side of the torso and reach behind the body with the wrist joints dorsally extended, fingers as far up as possible and the jaw raised upward.
Step 13: Place both upper limbs loosely on the side of the torso and gently shake the hands.
Doctor’s Tip.
The whole set of activities can be completed once before work and once between work or after work, and steps 1 to 6 can be performed at any time. The whole activity should be continuous, slow and coherent. Each step should be held for about 5 to lO seconds. Before choosing this method, patients should consult with the doctor concerned and explain their specific situation to confirm whether it is appropriate to use this method to avoid unnecessary injury.
