What we screen

The 17 posture metrics, explained.

Every PosturaScreen assessment computes 17 measurements grouped by anatomical region. Each comes with a value, a normal range, and a clear flag.

Head & neck.

Two views, two questions: is the head tilted side-to-side (front view), and does it sit forward of the shoulders (side view)? Both are the most common findings in desk-and-screen populations.

Front + side
MetricExampleNormal
Head tilt FV1.8°< 3°
Forward Head SV approx14.1°< 12°

Shoulder symmetry.

Are the shoulders level? Two complementary measures: a vertical offset in centimetres and the clavicle's angle relative to horizontal. Reported per side so it's clear which shoulder is higher.

Front view
MetricExampleNormal
Shoulder level (vertical Δ)1.8 cm< 1.5 cm
Clavicle angle2.1°< 5°

Spinal alignment.

Side-view curvature estimates: the upper-back roundedness (kyphosis) and the lower-back curve (lordosis). Both are screening estimates derived from surface landmarks and tagged accordingly.

Side view
MetricExampleNormal
Thoracic kyphosis approx36°20–45°
Lumbar lordosis approx34°20–60°

Pelvic balance.

Two views again: a frontal level (left vs right hip height) and a sagittal tilt (anterior vs posterior pelvic rotation). Together they describe pelvic orientation in 3-D space.

Front + side
MetricExampleNormal
Pelvic level (frontal) FV0.6 cm< 1 cm
Pelvic tilt (sagittal) SV approx< 12°

Knee alignment.

The Q-angle — the angle formed by the line from hip to knee centre and from knee centre to ankle. A screening proxy for valgus or varus tendency, reported for each leg.

Front view
MetricExampleNormal
Q Angle (L) approx14.2°M < 18° / F < 22°
Q Angle (R) approx13.1°M < 18° / F < 22°

Side-view summary.

The side view is where most posture screening lives — it shows the head's forward position, the spine's curves, and the pelvic tilt in one shot. All six side-view metrics in one table.

Photo quality & limitations.

Before measuring, each photo is checked for pose-detection confidence and full-body coverage. A clear, full-body shot passes silently. If the model isn't confident — poor framing, occlusion, low light, or a cropped body — the report shows a quality notice so you know to re-take.

Every assessment

How the quality gate works.

Clear, full-body photo Pass
If a photo is too unclear or cuts off the body, the report carries a "Photo quality may affect accuracy" notice — so a low-quality capture is never silently trusted.
Limitations to know
  • 2-D estimates. All metrics are computed from a single front + side photo. Rotational and depth components are inferred.
  • Clothing & occlusion. Loose clothing, hands in pockets, or accessories can degrade landmark accuracy. Tight athletic wear works best.
  • Approx tag. Spine curves and Q-angle are screening estimates — they're useful for trending, not for replacing radiographic measurement.
  • Not a diagnostic device. PosturaScreen supports screening and tracking; clinical decisions should integrate findings with examination and history.
