There are many causes of neck and low back pain, the most common causes being disc herniation, muscle strain, myofasciitis, etc. In addition to organic lesions, each of these causes is related to people’s labor and work. It has been reported that computer engineers, accountants, teachers, doctors, office workers and other people who work in the same posture for a long time are more likely to suffer from neck and lumbar pain than other occupations. In addition, neck and lumbar pain is also prone to occur because of exercise. An analysis of the X-rays of 200 patients with cervical spondylosis revealed that there were 149 people with straightened cervical curvature, 30 people with posterior protrusion and 56 people with scoliosis. These changes are associated with prolonged head bowing and can reduce the loading capacity of the cervical spine. Another study examined the forces on the lumbar discs in different postures: 1. In a relaxed upright position, the load on the third lumbar disc was twice as great as that on the disc above in a man weighing 70 kg. 2, in a relaxed and unsupported sitting posture, the load on the lumbar spine is greater than when relaxed and upright. 3.When in a sitting posture with lumbar support, the load above the lumbar spine is less than when unsupported because part of the upper body weight is supported by the spine. 4.When the trunk is bent, the pressure and stretching force are increased. 5, no weight load in the supine position, the spinal force is minimal. As seen above, in order to prevent neck and lumbar pain, ambulatory workers had better use the appropriate cushion to effectively reduce the load on the spine. In addition, every 1 to 2 hours of work, you should get up and stretch, 5 to 10 minutes of activity.
