Atlas (C1) Latency (Roll/Divergence) - Left and Right

Head rotation on the Atlantoaxial Articulation - Superior View

(Rotation with a stable Atlas)

Left Head Tilt resulting from a Left Atlas Latency

Above is the postural distortional pattern resulting from a left and right Atlas Latency - Pure Pattern (e.g., no ascending or occlusal factors)

Left Head Tilt without Atlas Latency

  • Head rotation is occurring on the Atlantoaxial Articulation

Left Latency (Roll) of the Atlas (C1)

Hypertonicity in the postural muscles on the right side of the body
Right Leg Functions Short

  • Right foot supinates to lengthen the functionally short right leg
  • Left foot pronates to shorten the functionally long left leg

Right Latency (Roll) of the Atlas (C1)

Hypertonicity in the postural muscles on the left side of the body:
Left Leg Functions Short

  • Left foot supinates to lengthen the functionally short left leg
  • Right foot pronates to shorten the functionally long right leg
