Hello.
Those days the gait3D model is used to get joint forces such as
hip,ankle and so on. The model is computed with the markers’
displacement values and force plate data. But how to get the reasonal
results?
Also when analysing used the model , from chartFX window reaction
forces of a contrsain ,such as in hip joint folder, could be got. What
are the different curves mean? The red ,yellow curves are for what? I
am exhausted.
regrads.
Alec
Hello.
I might have misunderstod your questions totally. With that said I’ll
go on.
Usually, the different colors of the curves descibe forces,
accelerations etc in different coordinates (directions). How to get
reasonable results? Well, I think you need to supply more input to be
able to get help from anyone.

Hi Alec
In the ChartFX window you can click on an icon which looks like a table, if
you hold the mouse over this icon it will say Data Editor, this will display
a table below the graph which will contain legends for the plotted data.
This will allow you to see which colors are representing the data.
Regarding the other question, I agree with Jokke, more info is needed.
Best regards

thanks for Søren and Jokke’s answer.
To be honest, the curves about displacement and acceleration could be
learned easily.But about reaction forces of the body modeling seem a
little different. For example,the hip joint forces.
the hip joint is a sphere joint and have 3 degrees of freedom. when
studing the joint forces, the curves in ChartFX window could be got
with the legend. the colors of force curve respesnt the same
dircetions as the displacements’.
Actualy, the hip joint force is devided into 3 directions. but how to
decide the exact one for each axis.
how can i learn it in detail?

Alec

Hi Alec,
The reaction force on the hip has 3 components: Reaction.Fout[0],
Reaction.Fout[1] and Reaction.Fout[2]. Component [0] refer to the
first axis (X in this case), components [1] refer to the second axis
(Y in this case) and component [2] refer to the third axis (Z in this
case). You can see in the legend box of the graph which colours
correspond to which component.
Notice that the forces are given in the local frame of the pelvis. So
the axis [0], [1] and [2] are the X, Y and Z of the pelvis.
I hope this makes it clear.
Best regards,
Sylvain, AnyBody Support.

Hi Alec,
Just a small correction: the hip reaction force is displayed in the
local frame of the femur and not in the frame of the pelvis as I said
in the previous message. Please take it into account.

thnks for Sylvain’s message.
It is very useful for me.
How could I take the pelvis frame into account? I have no idea about
it. what shall I do?
