Abstract
The main purpose of gait analysis laboratories is to measure and study human gait walking patterns in order to better understand and treat gait abnormalities. Gait analysis involves the measurement of kinetics/kinematics of joint move- ment, muscular activity, stride characteristics, pedobarography, and energy consumption. Kinetic data are measured with a force platform that provides information about ground reaction forces and when combined with kinematic data, can yield joint forces and moments. Joint angle and limb segment motion data or kinematic data are obtained by motion analysis systems such as electrogoniometers or photographic systems. Electromyography is used to identify muscle tim- ing and relative muscle intensity. Stride characteristics are used to measure gait timing events. Pedobarography deals with plantar pressure under the foot and the efficiency of gait can be measured with oxygen consumption analysis. Gait analysis is useful for research on normal and abnormal walking patterns, gaining a better understanding of a subject's gait, and planning treatment strategy. Index W
