What we screen

The 17 posture metrics in every report.

A front photo gives 11 metrics and a side photo gives 6. Each comes with a value, a normal range, and a clear flag. This page is the at-a-glance list; for what each metric measures and how to read it, see the posture metrics guide.

Metrics tagged approx are screening estimates from a 2-D photo. The thoracic and lumbar values are proxies read against X-ray (Cobb) reference ranges, and pelvic tilt is unsigned, so it shows how much, not whether the tilt is anterior or posterior.

Related guides: forward head posture, lumbar lordosis, anterior and posterior pelvic tilt, and uneven shoulders and hips.

Photo quality & limitations.

Each photo is checked for detection quality and full-body coverage. A clear, full-body shot passes silently. If the capture is poor — bad 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 photoPass
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 flat front and side photos. 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. Five metric types — Forward Head, Thoracic Kyphosis, Lumbar Lordosis, Pelvic Tilt and Q-angle (L/R) — 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.
