Upper Cervical Health Care for sick and suffering people who have been under-diagnosed or mis-diagnosed. The cranial cervical junction protects the base of the brain, the pons, the brainstem, and the medulla oblongata. The atlas vertebral subluxation may adversely impact your neurological health. which may cause sickness and dis-ease. Head/neck alignment is crucial for normal neurologic function. Your Upper Cervical Practitioner mathematically calculates the three directional head and neck X-ray misalignment. The atlas correction, a.k.a. the atlas adjustment, may align the head/neck relationship on post-corrective cranial/cervical X-rays. More normal neurologic function may be the result of upper cervical care.
