Negative Z with Headstrap

(1 customer review)

For skull-atlas displacement locked in flexion or extension. The Negative Z holds the atlas while the skull is flexed or extended, causing the condyles to rotate in the lateral masses of the stable atlas. The drop of the Negative Z with the thick foam padding makes the adjustment easy on both the patient and the Doctor while adjusting the skull on the atlas! Available in shorter drop (Baby Negative Z).

Uses & Benefits:

  • Adjust the skull on the atlas
  • Y and Y/A adjusting
  • Lateral skull on atlas adjusting
  • Extremity adjusting (knee, foot, etc.)

The head strap/halter is used for adjusting small children or patients who have difficulty holding their head and neck in the flexed position during adjustment.
