Yesterday, Hangzhou Binjiang small teacher Ding Xia sent a photo in the circle of friends, the photo, almost the whole class of children are using “writing corrector”, a “U” shaped bracket just erected in the chin here, the head want to lower can not.
This is a new tool introduced by Mr. Ding to prevent children from being nearsighted. In the photo, the children are straight back, sitting very properly. But will it be uncomfortable to sit like this for a long time and will it last?
In the afternoon, we went to the second (2) class of Binjiang Primary School, where the children were having an art class. Of the 38 children in the class, nearly 30 children still have orthodontic devices on their desks, and some children have forgotten their orthodontic devices at home and have not started using them.
This “writing corrector” is made of plastic, the lower end of the clip on the desk, the middle section has seven or eight small holes, according to the height of the child to adjust the height, the upper is a curved design, touch will not hurt.
Standing next to the observation for a while, a boy lowered his head to write, after a while to bypass the corrector, the head down, the teacher reminded him on the side, and only then raised his head again.
Standing next to the podium, the contrast is obvious, the back of the students with braces has been very straight, without braces a few students, some eyes only ten centimeters from the table, there are students are almost lying on the table.
Ding said that at the beginning of writing with the corrector will not be used to, so some children write and write down.
What does it feel like to use a writing corrector? We also had a taste of it. To keep your chin from touching the corrector, you have to keep your back straight, and if you lower your head a little, you will touch the corrector, so it is a little tiring to sit all the time.
Parents of lower grades.
I didn’t keep an eye on it for a while, and my head got into the table
The first grade teacher Ding Xia’s own children this year, writing posture is very bad, so she thought of the corrector. “Verbal supervision is not effective, a moment did not keep an eye on the table again to drill, reminded a little better, after a while again, adults and children are tired. Then I went online and bought a corrector, 24 yuan, and it worked quite well. At first he felt restrained, not used to, but almost a month down, has been much better.”
Last week, Ms. Ding recommended the brace to the parents in her class, and everyone voluntarily purchased it. “I told the parents about it in the group and there was an instant buzz, everyone was worried about their children’s writing posture and basically all the parents bought it. Last week, I asked a classmate to test a day, from this week onwards the whole class uniform use, a day down the effect is not bad.
”In fact, many children also have corrective devices at home, but a person at home, the child can not adhere to, and now we all use together, it is easier to adhere to.”
Ding teacher said that the number of elementary school students myopia increased every year, the more to the upper grades, the more children wearing glasses, sitting posture is not one of the reasons. Long-term improper sitting posture leads to eye fatigue and vision loss. Improper sitting posture also tends to lead to spinal curvature, some students hunchback not upright.
Ms. Ding has taken several classes of students, she said, some students do not have good writing habits, sitting posture is not correct, eyes closer and closer to the book, “small glasses” is also more and more. According to the data from last year’s school physical, there are many children in the first grade with vision below 5 or 0. From the data of the whole school, as the grade increases, the vision decreases significantly.
For this problem, Ms. Ding Xia has been working very hard. Last year, when she was in first grade, she took pictures of the children writing in order to make their posture more standard, and every time there was a student with a great writing posture, they were named “writing king. This time the “writing corrector” is an upgraded version of the “writing king”.
Prevent myopia by remembering four points –
Master the correct pencil grip posture
Avoid prolonged use of the eyes
Participate in more outdoor sports
Table and chair height difference should be appropriate
Chen Yan, director of the Department of Optometry at Zhejiang Eye Hospital and mother of a second-grade girl, said she had seen this writing corrector in her circle of parent friends.
”I think the starting point of this corrector is good, children can keep their eyes and books at a relatively fixed distance if they can insist on using it correctly, which really helps prevent myopia. It’s just hard to say whether children will be clever in the process of using it, such as going around from the left or right.”
Director Chen said that more than 80% of students who go to their hospital for optometric problems have sitting problems. Sitting is a common trigger for eye diseases such as myopia and refractive error. When doctors ask for advice, they usually ask these questions.
”Is your usual writing posture good?”
”Do you usually spend a lot of time reading at close range?”
”How much time do you spend with electronic devices?”
”How much time do you spend outdoors?”
In other words, the writing posture should be better, the close reading time should not be too long, the exposure to electronic products should be less, and the outdoor activities should be more.
According to Director Chen, an important factor that affects a child’s sitting posture is the pen holding posture. If the fingertips are too close to the pen when holding the pen, it will cover the words just written, and children will unconsciously lower their heads from the left front of the thumb in order to see the words written clearly. Either they will be too close to the book or they will have a crooked head causing refractive disparity. Therefore, to correct sitting posture, first correct the pen grip: the index finger and thumb pinch the pencil at a distance of about 3 cm from the pen tip, the pencil rests on the first joint of the middle finger, and the pencil and the paper are at an angle of 45 degrees.
In addition, choose the right height difference for the child’s desk and chair is also conducive to the child to correct sitting posture to prevent myopia. If the child sits in a chair that is too high, he will have to write on the table. Children in a quiet state, sitting straight back on the chair, eyes from the desktop in 30-40 cm, so the table and chairs matching is the most appropriate.
Using “writing braces”
Can you prevent scoliosis?
So if you maintain a good sitting posture every day, can you prevent scoliosis in children?
Professor Chen Qixin, chief physician and spine specialist of the Department of Orthopedics at the Second Hospital of Zhejiang Medical University, believes that sitting in a proper posture may help with physical grooming, but it may not have a corrective effect on scoliosis.
”Excluding scoliosis caused by other diseases, scoliosis in general is related to genes, that is, a genetic disease.”
Prof. Chen said that external factors have to work through internal factors. If there is a gene for scoliosis, the spine will be bent even if you sit upright; if there is no such gene, the spine will not be bent no matter how you sit.
Zhu Jian, deputy director and deputy chief physician of the Department of Orthopaedics at the Zhejiang University Hospital for Children, also said that he had not come across a single case of scoliosis that was clearly caused by sitting: “There are studies abroad where several siblings, one of whom has scoliosis, are examined by others and often have scoliosis as well. Our country has not found this problem because there are many only children.”
Zhu Jian, deputy director, said that if proper posture can affect scoliosis, then some children who grew up practicing dance and gymnastics must be particularly good posture will not scoliosis, but he also met a little girl, after practicing dance for a period of time, the spine is still scoliosis. “So I think scoliosis is more influenced by genetic factors.”
Professor Chen Qixin said the incidence of scoliosis is still very high, with three out of 100 people.
As for the various sitting posture correctors on the market, Professor Chen believes that they are basically useless for scoliosis. Even with plaster support correction, only for Cobb’s angle of 25 ° – 30 ° children under 10 years of age has an efficiency of 60%. If scoliosis is serious enough to be operated, it is best to do it around 12-16 years old.
However, Professor Tong Peijian, director of the Department of Orthopedics at Zhejiang Hospital of Traditional Chinese Medicine, believes that mild scoliosis can be caused by improper sitting posture and can be corrected by some self-correction or tui na techniques to improve the scoliosis phenomenon. Director Ye Shuliang of the Department of Tui-Na also said that Professor Hans-Rudolf Weiss, president of the European Scoliosis Association, had come to China to give a lecture on “Conservative Management of Scoliosis – Evidence, Indications and Best Treatment Practices,” saying that his mother’s scoliosis was corrected through self-exercise of posture.
”Self-posture correction does have a more limited effect on hereditary scoliosis, but it is still very effective for scoliosis that develops later in life.”
The methods of self-exercise for the spine offered by Director Shuliang Ye are.
1, walk a while every day cat walk, which is a model of a word step.
2, pull the bar, hands pulled on the bar, the foot can naturally hang down, the time to be able to bear the limit.
3, the left hand down, the right hand as straight as possible up, while the left foot off the ground slightly backward, but also as straight as possible, the weight on the right foot. Hold this position for one minute and then switch sides. Do this repeatedly for 10-20 groups, to the limit of their ability to bear.
4, such as the spine to the left side of the bend, the right half of the ass side sitting on the chair, the upper body to the right leaning on the back of the chair, so sit for 20-30 minutes. And vice versa.
5, swallow fly. Lie on your back, stretch your limbs back as far as possible, pause for 3-5 seconds and then put them down, so do 10-20.
