What Is a Spinal Brace?

The number of spines born to a child is 32-34, and the adult spine consists of 26 vertebrae (7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 1 sacral vertebrae (5 at birth), 1 tail vertebra) with ligaments, Joints and intervertebral discs are connected. The upper end of the spine supports the skull, the inferior hip, and the middle ribs, and serves as the posterior wall of the thorax, abdomen, and pelvis. The spine supports the torso, protects the internal organs, protects the spinal cord, and exercises. A spinal canal is formed inside the spine from top to bottom with a spinal cord (Note: The spine is not equal to the spine or spine, the spine is composed of multiple spines).

The spine is the central axis bone of the human body and is the pillar of the body. It has functions such as weight bearing, shock absorption, protection and exercise.

The load of the spine is above a certain level

Normal human spine has a certain degree of movement, but the movement of different parts is different, the neck and waist are more active, the thoracic is extremely low, and the iliac is almost inactive. In general, the neck can be flexed forward and backward 35 ° ~ 45 °, left and right sideways 45 ° each, and rotated 60 ° ~ 80 °. Under the condition of fixed hips, the waist can be flexed forward 75 ° ~ 90 °, extended backward 30 °, left and right side bends 30 ° ~ 35 °, and rotated 30 ° ~ 35 °. During the examination, the physician fixed the patient's shoulder, and instructed the examinee to perform exercises such as anterior bow, back tilt, lateral curve, rotation, etc .; To check the thoracic vertebral activity, the pelvis can be fixed first, and then the shoulder should be rotated. Pay attention to observe for abnormal changes.
