About 1/3 of adults over the age of 30 will experience degeneration of the spine (cervical, thoracic, and lumbar). In your daily life, you can determine whether your spine is healthy through some simple checks and controls. 1.If the heel of your shoes are often worn high or low, it is usually due to the unequal length of the legs or the uneven pressure along the long axis of the spine. 2, you can not complete a very comfortable deep and long breath, breathing, health, spinal health and vitality are closely linked to each other. 3, Your jaw makes a “clicking” sound when you move it, mostly due to a subluxation of the neck or hip. 4, Your neck, back or more joints will make a popping sound, usually because your spinal joints are locked or stuck. 5.Your head or hip can’t twist or rotate the same angle to either side easily, and the range of motion is gradually decreasing. 6.You often feel tired and your unbalanced spine drains your energy. 7.Your mind can’t concentrate well because a subluxation of the spine can affect brain health. 8.Your resistance to disease is weak, and subluxation of the spine affects your neuroendocrine system. 9.Your feet spread outward when you walk on your toes. 10, One leg appears shorter than the other.
