I have need of some way to compare and assess the relationship between two
or more motion vs time curves during walking. I am working in the foot and
have 3D data on the tibia, hindfoot, midfoot and first ray during walking.
I would like to know how much, if any motion at one segment contributes to
another. I have used pearson correlation coefficients, but it seems to be
fairly non-specific. Correlation of specific points on the curve also has
proven disappointing. Does anyone out there have any suggestions? I would
appreciate any help you could give me. Thanks in advance.
