First, the dangers of straightening the physiological curvature of the cervical spine Many people may think, “The cervical curvature has straightened, if so what harm will it do to the human body?” In fact, the evolution of the human spine is a very long and intelligent process, full on drama. The normal cervical curvature (forward) exists to adapt to the needs of humans walking upright, the cervical physiological curvature acts as a shock absorber for the human body, for example, when we run, jump, the physiological curvature of the cervical spine will greatly reduce the impact of the weight of the head on the cervical spine in the shock; conversely, when our cervical curvature (pathology) becomes straight, the cervical spine lacks shock absorption, when we then do jumping, running and other actions, the head weight will be directly impacted on the cervical spine, stimulating the intervertebral discs and further developing into anti-arch. It can also cause cervical disc protrusion, stimulate the nerves and blood vessels causing hand numbness and dizziness, and compress the spinal cord back causing weakness of the lower limbs. In clinical practice for more than 10 years, I believe that people with thin necks and large heads are more likely to have abnormal cervical curvature, while people with short necks, broad shoulders and moderate heads are indeed less likely to suffer from cervical spondylosis, or have a smaller probability of suffering from cervical spondylosis, even if they are diagnosed and treated with Chinese orthopedic manipulation and acupuncture, the symptoms are relieved very quickly. Therefore, although the straightening of the physiological curvature of the cervical spine is not clinically considered a type of cervical spondylosis, it is indeed a pathological form expressed on cervical spine X-rays, especially for adolescents, and may be an early pathological change of cervical spondylosis. Why is there a straightening of the physiological curvature of the cervical spine? This has to start from the soft tissues around our cervical spine such as muscles and ligaments. For example, our cervical spine is like a “Wuhan spicy duck neck”, in addition to the bones we see on the X-ray, there are many difficult and intermingled muscles and ligaments around. These muscles and ligaments are mainly divided into three layers: these muscles, ligaments, similar to rubber bands to maintain the normal physiological curvature of our cervical vertebrae, due to modern work, entertainment, travel has changed the way, head down for an increasingly long time, resulting in the posterior cervical muscle group in a long-term passive tension stretching state, while the cervical spine muscle group in a long-term contracture state. Over time, the posterior cervical muscle group exceeds the limit of being stretched, the elasticity decreases, the strength of the posterior cervical muscles decreases, and the muscle tension behind the cervical vertebral body decreases, gradually the problem of straightening the physiological curvature of the cervical vertebrae appears. Third, how can we change the straightening of the physiological curvature of the cervical spine? Doctors suggest that if there are pathological changes such as cervical spine straightening, reverse arch, disorder and misalignment. First of all, usually do not lower your head for a long time, do not have a pillow that is too soft and too high, and avoid trauma. Secondly, increase the exercise of neck muscle groups, neck counter stretching, swimming, etc. Finally, if there is neck with upper limb numbness and pain, it can be treated by orthopedic acupuncture and so on.
