1. A method for locating a system of motion sensors on a human or other animal body for capture of movement time history, comprising the steps of:

  • 1a) determining mathematical transformation matrices between coordinate systems of sensors strategically positioned on a human or other animal body and skeletal coordinate systems to produce a kinematic model of the human or other animal body;

    1b) refining the transformation matrices of the kinematic model to minimize anatomical joint gap error; and

    1c) monitoring the anatomical joint gap to detect and correct for sensor slippage during data collection.
