The adjustment of the atlas by the Atlas Orthogonal Percussion Instrument is gentle and specific. The stylus of the instrument is placed between the ear and jaw, contacting directly over the atlas vertebra. Only six pounds of force is delivered to the patient in order to achieve a correction. This amount of force is sufficient because the adjustment is very fast and very precise.
There is no guesswork regarding whether the treatment was successful or not. A proper correction will instantly affect the balance of the spine, which is evaluated with the relative leg length measurement. The doctor should feel a significant relaxation of the tissues of the upper neck on palpation. In addition, the patient should notice that the tenderness and spasm in the upper neck should be diminished. Many patients notice instant changes in range of motion and pain levels, as well.
