Attention, mobile phone slaves! Press the HOME button often. Experts say be careful of this disease.

  Cctv newsNowadays people’s lives are gradually surrounded by intelligent tools such as computers and mobile phones. As the screen of smart phone is getting bigger and bigger, while users enjoy the pleasure of big screen, there are some information age diseases such as "mouse hand" and "mobile phone hand". Recently, some biomedical experts have warned that "mobile phone users" cannot be ignored.

  What is a "mobile phone hand"?

  It is a common thing for many people to type with their thumbs and press the HOME button on their smartphones every day. However, it is such a small action, repeated every day, the harm to the thumb can not be ignored. Thumb will have discomfort symptoms such as pain, which is what medicine says.Tenosynovitis of thumb”。

  In the past, the main group of tenosynovitis patients was middle-aged and elderly people who did manual labor, but now because ofTenosynovitis is gradually becoming younger due to improper posture of using mobile phones and frequent use of electronic products such as mobile phones and tablet computers.

  Why do you get a "mobile phone hand"?

  Use the phone for a long time with one hand.

  Nowadays, with the popularity of smart phones, many citizens have developed the habit of playing mobile phones with one hand. In the long run, due to improper operation posture, there are more and more "mobile phone hands".

  Experts said that from the occurrence of tenosynovitis, it is mostly inThumb, middle finger and forefingerThree fingers, these people’s finger activities have several characteristics: First,fast; The second isHigh strength; The third isa long time. If you play mobile phone for a long time, it fully meets the above characteristics.

  The screen size of using mobile phone is too large.

  Nowadays, it seems to be a trend that the screen of mobile phone is getting bigger and bigger. The screen of smart phones is getting bigger and bigger, and citizens will face the threat of tenosynovitis while enjoying the pleasure of the big screen. For a small hand with a big mobile phone, the angle of wrist extension and finger movement will exceed the general angle range, which will cause excessive friction of tendon and extrusion of joint capsule for a long time, and if the finger repeats a certain action repeatedly, it will also cause finger nerve injury.

  Many net posts believe that for most users,The most suitable mobile phone for hand size is the 4-inch model, and the width of the mobile phone should not exceed the distance from the tiger’s mouth to the middle section of the index finger..

  speicalHome Tip: Change the posture of mobile phone use and beware of "mobile phone hands"

  In order not to be a "mobile phone user", the key is to change the operating habits and reduce the frequency of use. It used to be a mobile phone with one hand.It is best to hold the mobile phone in one hand and use the other hand to touch the screen of the mobile phone. It is best not to stroke with your thumb, but to "poke" the screen with your fingers..

  When you use your mobile phone, rest your thumb properly, type with the remaining fingers, or send messages by voice. Of course, it is also necessary to move your fingers frequently.

  Tip: How to avoid tenosynovitis in daily life

  1、Pay attention to the correct posture of fingers and wrists.Don’t bend or stretch back too much when doing housework such as washing clothes and cooking; Don’t carry things too heavy; Don’t use too much force on your fingers and wrists.

  2、Warm and hot compress:Get into the habit of washing your hands with warm water, not cold water. Pay attention to keeping your hands warm in winter and wear cotton gloves to prevent your hands from getting cold.

  3、Maintain a comfortable position:The nursing of tenosynovitis needs to avoid arm drooping. When sleeping, patients with tenosynovitis need to keep their arms close to their bodies and their wrists are not bent.

  4.、Self massage:The wrist joint rotates 360 degrees; Or make a fist with your palm and relax, and do it back and forth several times; Or a few times of finger back pressure or palm back pressure can effectively relieve hand pain.

  5、Take a timely rest and maintain a correct working posture.For long-term desk office workers, they should adopt correct working posture, try to keep their hands balanced, and their wrists can touch the real thing, so as not to be suspended. Take a break between work, put your hands on the table and rotate your head for 2 minutes.

The Frontier of Science and Technology | See how AI doctors crack down on "invisible killers" that endanger the health of teenagers

Cover journalist Tan Yuqing Bian Xue

In recent years, scoliosis has become a common disease that harms teenagers, making it difficult for sick teenagers to straighten their backs. According to statistics, the number of scoliosis among primary and secondary school students in China exceeds 5 million, and it is still increasing at a rate of about 300,000 per year. Scoliosis has become the third major disease that harms the health of children and adolescents after obesity and myopia.

Early detection, early diagnosis and early treatment are the key points to combat scoliosis, otherwise it may develop into a very serious deformity, which may affect cardiopulmonary function and even lead to paralysis in severe cases.

Scoliosis model

In the past, doctors would diagnose scoliosis by manual measurement and X-ray screening, but with the integration of artificial intelligence (AI) into medical imaging technology, this step may be further optimized. In the screening stage, it is only necessary to "simply take pictures" to preliminarily determine whether scoliosis occurs, and in the diagnosis stage, the "experienced" AI system can also assist doctors to quickly read films for diagnosis.

Why can taking pictures replace x-rays? How does AI system assist doctors in screening and diagnosing scoliosis? Recently, the cover journalist explored the development of AI+ medical imaging technology.

It only takes a few seconds. Did the AI system tell you about scoliosis?

In the "simulated physical examination room", the reporter saw the hardware part of the spine AIS intelligent screening and diagnosis system (hereinafter referred to as the "system")-a rectangular metal frame about 2 meters high, with a group of small cameras in the center of the top. It looks simple, but the effect is not simple. The reporter’s on-site experience found that it took only a few seconds from detection to obtaining the report results.

The hardware part of the system is the camera.

"As long as the examinee stands in a standard position and poses Adam’s position to expose his back, the system can quickly complete the screening by using an infrared depth camera to collect information on his back." According to Fan Jipeng, the person in charge of the Shuangxin Department of Chengdian Gold Disk, the system will map and transform the image information collected by the camera to get the depth information of multiple posture key points on the back, so as to calculate the back asymmetry index and judge whether the subject may have scoliosis.

He said that this intelligent system will get closer and closer to the level of X-ray diagnosis by constantly learning actual cases and optimizing existing algorithms. While ensuring the accuracy and efficiency of screening, it can also prevent the teenagers being tested from being exposed to X-ray radiation.

This new technology may help to better implement the scoliosis examination project that was included in the physical examination of students in 2022. "We think the greatest significance of the screening system is that it can quickly complete large-scale examinations, so that children with scoliosis who have not yet been discovered will not be delayed."

Interface of scoliosis diagnosis system

In the diagnosis stage, the intelligent system is also a good assistant for doctors. Fan Jipeng explained that in the traditional process, in order to diagnose scoliosis, doctors need to measure the Cobb angle of the spine with a ruler, but this is time-consuming. Different doctors will make some errors when measuring by hand. Doctors with less experience may need to consult for scoliosis with large curvature, and the diagnosis time will be prolonged. However, after deep learning, the artificial intelligence system can accurately read and measure the film within 3~5 seconds, and give diagnosis suggestions.

At present, the system has completed the screening and diagnosis of more than 5,000 cases of scoliosis. "Now we are cooperating with Electronic Science and Technology University Hospital, Zhongshan Pok Oi Hospital and Shenzhen Children’s Scoliosis Center, and this number will be continuously updated."

Training "AI Good Doctor" by "Engraving" Algorithm of Expert Experience

"The accuracy of top doctors’ diagnosis of scoliosis may be 85%~90%, and the overall accuracy of our system will continue to approach this figure." Fan Jipeng said that at present, of course, the accuracy of top experts is higher, but compared with ordinary doctors, the system may have exceeded their basic level.

So, what gives the diagnosis system the ability to catch up with top experts? The answer is the experts themselves.

"When experts mark the angles of thousands of scoliosis cases, the system will learn based on this and solidify the experience of top experts into the algorithm, thus reaching a higher diagnostic level." In Fan Jipeng’s view, although the system is not as good as top experts, it is used to assist ordinary doctors in diagnosis or help improve their medical level.

The marked samples provided by human experts are the "success stories" of artificial intelligence doctors, but Fan Jipeng said that this is also one of the difficulties in the development of AI doctors. Different races, even people in different regions, will have certain differences. If the diagnosis is accurate enough, researchers need to collect as many samples as possible for AI to learn.

At present, the real large-scale landing of the system still faces some difficulties in the process. "How to make the medical examiners go through the inspection process quickly and how to ensure that their Adam posture is standard requires some corresponding training."

Therefore, the system will learn more practical cases, further optimize its algorithm program, continuously improve the diagnostic accuracy, and design detailed operating standards for the system, "for example, what is the standard Adam position, how to do it well, etc."
