Dear members,

in order to describe the angular kinematics of the left side of the body (in particular the upper body) which is the best method recommended?

Whereas I use the global coordinate system defined as: Y vertical, pointing upward, X pointing from left to right, Z pointing backward.

I tried to reverse only the sign for the X-coordinate of each raw marker (3D data expressed in the global coordinate system).

Doing so, I can avoid left-handed coordinate systems or changes of definition for each anatomical reference system (using the same matlab program for both sides, instead of define a similar reference system/program for the left side, too).

Repeating the same procedure for the Z-coordinate.... it seams that I get the same result?

Any ideas would be very much appreciated.

Thanks,

Marco
