O 111 - accuracy of the conventional gait model : preliminary results

The Conventional Gait Model (CGM), distributed as Vicon Plugin gait (Vicon PiG) became a standard in the field of 3D Clinical Gait Analysis. Its reliability is assessed thought repeatability tests. On the other hand, accuracy of the CGM in terms of underlying bone motion has never been quantified. It’s all the more important CGM outputs might orientate a patient towards bone surgery. Thanks to a consensus, data from invasive approaches are available in open-access. They can serve as basis for model validation. This communication proposes to assess the knee kinematic accuracy of the CGM with fluoroscopic data during a gait cycle
