About
3Diagno — 3D Biomechanics & Clinical Simulator.
3Diagno is a comprehensive digital simulator providing a realistic, fully articulated 3D model of the human musculoskeletal system to help students visualize and professionals demonstrate complex biomechanical movements in 3D space.
Designed mostly for physiotherapists and sports educators, 3Diagno offers a high-fidelity interactive environment for clinical reference and education.
Key Features:
• Reliable Accuracy: Explore a high-fidelity model with detailed layers for the skeleton, muscles, nerves and anatomical landmarks.
• Precise Range of Motion Controls: Manipulate individual joints through clinically relevant ranges using a precise control system, with normal range-of-motion references included for educational comparison.
• Orthopedic Special-Test Demonstrations: Access a built-in library of all the published orthopedic special-test positions and visual demonstrations for reference.
• Simulator Recording & Replay: Record and replay movement sequences performed by the internal 3D model to study segment responses and biomechanical chains.
• Interactive Simulation Workflow: Utilize a neutral pose reset and a simulated patient assessment workflow for clinical documentation practice.
• Visual Customization: Toggle between anatomical layers and landmarks to isolate specific movement during biomechanical demonstrations.
Intended Use & Disclaimers:
3Diagno purpose is to become your quick handy educational reference.
• Simulation: All "Movement Recordings" and "Patient Tests" are performed only on the internal 3D musculoskeletal model for demonstration.
This app does not record live user movement nor access camera for diagnostics nor store any data in it.
• No Independent Diagnosis: This tool does not independently diagnose medical conditions and is not a replacement for professional clinical examination, medical imaging, or expert judgment.
