Lumbar intervertebral disc herniation, cervical spondylosis, thoracolumbar posterior joint disorders and spinal related diseases and other spinal intervertebral soft tissue injuries (referred to as intervertebral disease) are some common stubborn diseases. Relevant surveys show that 97% of the middle-aged and elderly people in my country suffer from spinal diseases. In recent years, there has been a trend of younger people. Among people under the age of 45, more than 40% suffer from various types of spinal diseases. Children The incidence of scoliosis is as high as 25%. With the continuous development of our society, office white-collar workers, students, teachers and other people have been sedentary for a long time due to the long-term lack of effective activities and exercise, and long-term accumulation will cause spinal injuries. In addition, waist injuries will also affect the lives of motor vehicle drivers for a long time. The application of the lumbar traction system has expanded from traditional manual workers to a wider range of people with lumbar injuries.
