You have to apply a geometric definition of what you mean by "movement".
For example, certain distances or angles between atoms or centers of
mass of different atom groups. Or a root mean squared deviation of the
ligand atoms following a RMSD-based fit of the protein.
All of this trajectory analysis can be run with the "cpptraj" program of
AmberTools, but you must first devise a rigorous definition of what you
want to quantify (or qualify).
