On the accuracy of the Conventional gait Model: Distinction between marker misplacement and soft tissue artefact errors

Kamiar Aminian, Arnaud Barré

There is a lack of knowledge about the accuracy of the Conventional Gait Model (CGM), compared to the true bone motion. Accuracy is hindered by both marker misplacement and soft-tissue artefact (STA). The effect of the lateral knee marker (KNE) misplacemen ...
