- | This project adds functional knee joint axes determination (SARA) to the default Vicon PlugInGait model. It works together with the old Vicon Workstation system. | + | This project adds functional knee joint axes determination (SARA) |
- | Additional | + | 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 |
- | ====Eclipse entries==== | + | The proximal tibia (anatomical) coordinate systems are defined by PiG virtual markers. |
- | To process the data, specific dynamic calibration trials must be done and its specific eclipse entries must be set: | + | |

+ | ====Modelparameter files==== | ||
+ | Modelparameter-files are needed to read parameters from clinical measurements, | ||
+ | |||
+ | There is an important limitation in the mechanism to work with these files: You can have an mp-file only for each session and not for each group. That is why the mp-files are found only, if they are saved in the session and not in the group. Details of working with .mp-files and its limitations you can find [[http:// | ||
