Chin-Up / Chin-Down (Cervical Tilt)

Also known as: cervical extension, chin poke, looking-up posture.

What it is

This is the up/down angle of the head. A lifted chin is cervical extension, which compresses the back of the neck; a dropped chin is excessive flexion. A level, neutral gaze is the goal.

How to spot it

From the side, the gaze and chin angle clearly up or down rather than level. The scan measures the ear-to-nose angle against a neutral baseline.

Muscles involved

Typically tight: suboccipitals, cervical extensors

Typically weak: deep cervical flexors

How to correct it

  • Chin tucks to a neutral, level gaze.
  • Release the suboccipitals; activate the deep neck flexors.
