The 4D motion system for dynamic spine measurement is the key technology for the developement of the 4D motion Lab. This motion laboratory allows the synchronized measurement of the whole musculoskeletal system in a small amount of space and with easy preparation. Components: DIERS 4D motion® Dynamic measurement of the spine, vertebra and pelvis with 50 fps. DIERS leg axis Video Gait Analysis for the detection and measurement of leg axis. DIERS pedogait Treadmill with integrated pressure plate
