The purpose of this study resulted from a need to gather and analyze data on gait characteristics of normal children using the Peak Performance Technologies, Incorporated system, initiate a data base for the Motion Analysis Center at Old Dominion University and compare a computerized motion analysis system to studies using different methods. Fifteen children, aged four to six, were evaluated during gait using a video-based computerized motion analysis system manufactured by Peak Performance Technologies, Incorporated. The gait characteristics studied were stride length, cadence, angular displacements and angular velocities of the pelvis, hips, knees and ankles. The results showed that methods to measure angular displacements of the pelvis as well as femoral and tibial rotation were unreliable. Hip displacements in the sagittal plane showed increased flexion of fifteen degrees when compared to previous studies but were · in agreement with hip motions in the frontal plane. Angular displacements of the knee and ankle were in agreement with previous studies except at terminal stance, increased knee flexion was measured. Cadence was in agreement with previous studies however this study had a large standard error and is not considered to be a desirable method for data collection. No studies were found with which to compare angular velocities of the pelvis and lower extremities. This information will serve as a baseline for future studies.
