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.
