A 2013 survey of 150,000 middle school students in Guangdong province showed that 5.3% suffer from a crooked spine. Most of them are girls between the ages of 10 and 15.
Nationwide, according to professor Yang Junlin of the center for clinical research in spinal cord deformation at the Guangdong Zhongshan First Hospital, there are 3 million people who have a crooked spine in China, and 80% of them are between the ages of 10 and 15. A vast majority of them, 95%, do not need corrective spinal column surgery.
A daily 15-minute to 30-minute corrective rehabilitation exercise and wearing a corrective back brace can correct the problem.
What irks me is that this doctor says that the causes of a crooked spine is unknown.
Unknown to this “blind” doctor is that middle school students between 10 and 15 years old are at the age when the body and the spine grow rapidly right before girls reach their adult height at around 16 and boys around 17 years old.
It is during this period that the spine also grows longer with the rapid increase in body height. It is also the period when the growing spine is the weakest in bearing uneven shoulder loads.
That heavy shoulder load is the heavy school bag and the heavy books that junior high and middle school students have to carry everyday, morning and evening, for the usual three years of middle school.
Crooked spine is seen mostly in girls of 15 years old even in the United States.
