A Quantitative Method for Assessment of Differentiation Techniques Used for Locomotion Analysis

Photogrammetric techniques are widely used for the study of human movement. These techniques allow the 3-D positions of anatomical landmarks to be determined at regular time intervals. The development of computer interfaced optoelectronic measurement systems has significantly reduced the time and manual effort involved in data acquisition, making the use of photogrammetry in locomotion analysis feasible on a routine basis. These perspectives have provided the impetus for the application of time series techniques for determining velocities and accelerations of limb segments.
