Ultrasound-based measurement method for gait analysis using treadmill

Abstract The present paper will focus on the presentation of a new 3D motion analysis technique at treadmill walking. The ultrasound-based 3D measurement system and developed measuring arrangement were used to measure and to determine the gait parameters during treadmill walking. The model considers each limb segment to be rigid body, linked to each other by a joint. The present paper wi ll also focus on the presentation of a new 3D motion analysis software package at treadmill walking and the introduction of the developed DataManager. We studied the knee kinematics and temporal-distance gait measurement parameters (step length, stride length, stride width etc) to be obtained from treadmill walking. These measurements were highly correlated with and not significantly different to those in literature. The treadmill walking allows analyzing more cycles of each subject. On basis of analysis it can be establish the standard deviation of the temporal-gait parameters and knee kinematics data of each subject. The presented 3D movement analysis system is a suitable and standardized procedure for the gait analysis.
