1. The atlas supports the weight of the head most efficiently in an orthogonal (90 degree) position. This orthogonal position refers to the atlas being 90 degree to the center of the head and the cervical spine.
2. If the head and neck are not orthogonal, imbalance occurs as the body shifts and distorts with compensatory adaptation resulting from atlas subluxation. (signs and symptoms of upper cervical/atlas distortion.
3. Compensatory changes include: pain and nerve disturbance from nerve irritation, postural shifts, reduced of painful range of motion, and muscular spasm or imbalance. These compensatory changes lead to compromised health and countless serious health conditions.

These compensatory changes lead to compromised health and countless serious health conditions:

• Postural Distortion
• Restricted or Painful Range of Motion
• Abnormal Spinal Curvature
• Muscular Tension and Imbalance
• Bilateral Weight Difference
• One Leg Shorter Than the Other
• Spinal Decay Resulting From Long-Term Unresolved Structural Distortion
