Cervicogenic (neck-related) headaches
There are different kind of headaches such as migraines, tension headaches, cluster and sinus-related headaches. The one that physiotherapists can most certainly treat quite successfully is the headache related to neck muscle tightness and misalignment of the neck vertebrae, especially the top 3 vertebrae. Nerves to the head exit out through apertures between these vertebrae so any misalignment can irritate them.
When assessing a patient with cervicogenic headaches, it is important to assess whole body alignment with special attention to any lateral tilt or rotation of the vertebrae. This can of course be a compensation for any rotations in the skull, thorax or pelvis. The head and neck can mirror the rotation or go in the opposite direction to ensure that the eyes stay looking forward.
Ideally all parts of the body should be symmetrical, centered, and evenly rotated left and right when standing or sitting. The neck, head, shoulders, hips and trunk should be level and facing forwards without one side more forward than the other.
