Abstract- A study has been conducted on the kinematic characteristics of infant crawling motion. The characterization of this motion requires motion data acquisition via a three dimensional, high-speed camera system (VICON - 200 Hertz) which records in time the cartesian coordinates of various points (reflective markers) placed on the subject's approximate anatomical joints. Data is transferred to a digital computer in the form of ASCII files which are used to synthesize the motion into angle-time, angle-angle and event-time diagrams through smoothing techniques and Fourier harmonic analyses. It is felt that information of this nature will provide the means to characterize normal patterns, to identify abnormal ones and to assess the effectiveness of therapeutic interventions in children with neuromotor dysfunction.
