Straight neck


Straight neck


Ideal or normal cervical spine has 42 degree curve. Straight Neck (A.K.A Military Neck) is defined as 0 degree of cervical spine from side view. The more one’s cervical spine loses its curve, the more likely to develop symptoms such as headache, neck pain, stiff shoulder or dry-eye.


  • ① Bad habit (posture when using smartphone or PC)
  • ② Whiplash
  • ③ Muscle imbalance


The green line is an ideal or normal curve, and the red one represents a patient’s. The photo on left is before CBP®︎ (Chiropractic BioPhysics) correction, and the one on right is after 3 month correction. You can see a clear change in the red lines from being straight to restoring a more natural curve.
