Attention chiropractors, physical therapists, athletic trainers, massage therapists, trainers and coaches: trade subjective visual impressions for camera-based measurements you can capture in seconds, repeat, compare and hand to the person in front of you. PostureScreen Mobile is a professional documentation and education platform built on semi-automated, AI-assisted digitization of posture, movement, range of motion and body composition. Its measurement methods have been examined in multiple peer-reviewed studies demonstrating reliability and validity, and it has been used as a measurement tool in numerous published studies. Used in practices, gyms, studios, corporate wellness programs and classrooms by professionals who document posture and movement. NEW — PostureScribe.AI Ambient Scribe Module (USA Only) An optional documentation assistant that drafts structured notes, narratives and client summaries from your client interaction history fused with captured measurements. You are the author: you review, edit and approve every word. WHAT YOU CAN DOCUMENT • Advanced posture documentation with markerless AI-assisted digitization • Functional movement screens (squats, planks, push-ups, single-leg tests) • Spinal & shoulder ROM using computer vision + accelerometer/gyroscopic sensor fusion • Body composition with LeanScreen® — validated and reliable, examined alongside DEXA and BIA in a UCLA-led study • Side-by-side comparative reports for progress tracking • Patient-friendly & clinician-detailed PDF reports • Remote capture using the RemoteScreen® app • Metric/Imperial units COMPREHENSIVE DOCUMENTATION SUITE — POWERED BY COMPUTER VISION Postural Documentation (AP & Lateral) • Automatic calculation of postural metrics from points you place or confirm • CVA (left, right, average), gaze angle, thoracolumbar displacement, sagittal plane tangent angles, pelvic tilt and Q angle • Semi-automated 2-view and 4-view reports, linear (mm) and angular (degrees) • Editable templates for documentation, education or research workflows Range of Motion & Mobility • Cervical: flexion, extension, lateral flexion, rotation • Thoracic/lumbar mobility and trunk motion • Shoulder: abduction/adduction, flexion/extension, internal/external rotation Movement Screening • SquatScreen® (lateral, AP, PA, single-leg) and Push-Up Screen PostureScreen records and displays what you digitize or confirm and what the gyroscope and accelerometers measure under your control. Where published reference ranges exist, it shows them beside your measurements and marks values above or below range — how the numbers compare, not what they mean or what to do about them. That judgment is yours, and it stays yours. PURCHASE AND SUBSCRIPTIONS Initial purchase includes 30 days Unlimited Assessment and Modules. After that, a monthly or annual Unlimited Assessment subscription is required to keep capturing new screenings.
