What this tool does
Compute joint angles and clinical flags from a single photograph. Four preset landmark kits cover common assessment scenarios — full-body lateral and frontal, lower-limb Q angle, and upper-limb/shoulder. Everything runs locally in your browser; the image is never uploaded.
Step by step
- Load an image (JPEG, PNG, HEIC) and choose the matching view — lateral (sagittal) or frontal (coronal).
- Pick a preset: full body lateral, full body frontal, lower limb (Q angle), or upper limb / shoulder.
- Click each landmark in order — the prompt on the image tells you which point is next. Use Undo or Clear to correct.
- Read the results: joint angles, asymmetries, plumb-line deviations, and a clinical flag (Normal, Mild, Notable) for each measure.
- Save PNG of the annotated image or Send to Dashboard to push the computed angles to the Data Dashboard.
Tips
- Flags are based on published reference values (Kendall et al. 2005; Norkin & Levangie 2011; Magee 2014; Myer et al. 2010) — they are reference points, not a diagnosis. Clinical interpretation requires professional judgement.
- Shoot square-on to the subject with the camera at hip height to minimise perspective error.
