In the gait trials the lateral knee markers are projected onto the functional knee joint axes and the knee joint center is determined based on the clinical measurement of the knee width. Than the femur coordinate system is constructed equivalent to the original PiG. Keep in mind that this coordinate system does not have the functional axis as one of its axes. The axes are defined by cross products and have the longitudinal femur axes included. | In the gait trials the lateral knee markers are projected onto the functional knee joint axes and the knee joint center is determined based on the clinical measurement of the knee width.

+ | You can see Intervals of frames defined by start- and end-frame enclosed in "[ ; ]". In these intervals the calculation cauld not be done. Typically the origin of this are unlabled markers. You should go to Vicon Worstation to check this. | ||
+ | The information about the differences between PiG and functional PiG, given as an direction cosine angle between the corresponding two knee joint axes is print in blue but typically there is nothing wrong. But you should always have a look at it. If the differences is hight you should think about if this can be correct. |
