Atlas Orthogonal

Dr. Katie and Dr. Nor focus on a chiropractic approach called Atlas Orthogonal (AO), also known as Atlas Chiropractic or Upper Cervical Chiropractic, which targets the top bone in your spine, the atlas. This is the area in which any distortions in spinal function appear. It is the most important part of your spine as it protects your brainstem and nervous system.

To review the relationship between your spine and skull, pictures are needed of your spine. A side view can show the curvature of your spine and whether it is exaggerated or lost. A nasium view, which is taken with your mouth wide open, displays the relationship between your neck and head. Finally, the vertex view offers a view of your atlas in relation to your skull. These three images together can help Dr. Katie and Dr. Nor to calculate the angle of the adjusting instrument that will be used in this treatment.

Instrument Used

An instrument is used to achieve precise adjustments. It will barely touch your skin and moves quickly to create a pressure wave on your body. Energy transfers to your atlas, which moves the bones thanks to the four to six pounds of pressure delivered by the instrument.

The Results

Within minutes of the adjustment taking place with the instrument, some patients report a sense of warmth, while others even feel complete relief. Naturally, this treatment usually requires multiple appointments to retrain your muscles, and in turn, this will result in a better relationship between your spine and skull. This treatment method helps to encourage natural healing with your body, and nerve interference is minimized.
