What this metric measures
Body alignment is a movement-quality proxy. A 2D camera view cannot recover every 3D joint relationship and must suppress results when the viewing angle is invalid.
How Trampoline Lab calculates it
Versioned pose landmarks support trunk-angle, hip-knee-ankle alignment and symmetry features. Enhanced setups can add depth, ARKit or sensor orientation.
How to interpret it
Treat warnings as coaching prompts for video review, not medical findings. Confirm camera view and pose confidence first.
Limits and responsible use
Loose clothing, occlusion, camera angle and out-of-plane rotation can distort joint geometry.
