Head and Neck
Screens taken standing or supine with a side camera. The reference is a vertical plumb line dropped from the tragus; what matters is how far the head sits forward of it and how much the deep neck flexors can hold.
Forward Head
The tragus sits ahead of the plumb line dropped from the shoulder.

Self-screens at this station
-
Seated Head Drift Timer
Sit at your own desk, work normally, and time how long it takes for the head to drift forward of the shoulder line. This screen measures the position you did not choose.
-
Deep Neck Flexor Hold Test
A light nod, held on the back, timed until the chin lifts. It measures holding capacity rather than range, and the way the hold fails is the useful part.
-
Supine Occiput Gap
Lie flat and measure the space under the back of the skull. It removes gravity from the equation and reads the neck's resting position with nothing to hold up.
-
Chin Tuck Release Check
Correct the head position, hold it, release, and time how long it survives. This screen measures the release, not the tuck — how long the correction lasts without supervision.
-
Craniovertebral Angle from a Phone Photo
The angle between the tragus-to-C7 line and the horizontal, read from a single lateral photograph. One number, one frame, one camera distance held constant.
-
Side Photo Tragus Angle
A lateral photograph with two marks on it: the tragus and the C7 spine. The angle of that line away from vertical is the reading, and the cued photo shows whether it is reversible.
-
Doorframe Occiput Drop
A pencil, a door frame and 45 seconds. Mark where the back of the head touches, let the head settle, mark again, and measure the drift between the marks.
-
Wall Tragus Line Test
The simplest forward-head screen there is: a wall, a ruler, and the distance from the tragus to a vertical line. Two readings decide it — the resting gap and whether the gap closes on cue.
