Normative Human Gait Databases

Normative Human Gait Databases The human gait is uniquely characterized by its kinematics and kinetics. These characteristics are routinely used to analyse and evaluate both the normal and pathological gait. A lot of clinical studies, dealing with quantitative human gait analysis and published all around the world, use the normative gait databases to evaluate pathological gait, but only a few of them describe their background. However, this is an important factor as it makes the analysis objective and directly influences the interpretation of motion analysis results. There is also a lack of comparative studies that evaluate and compare such databases, acquired within different laboratories considering the age, typology and/or gender of included healthy/normal subjects. Therefore, the human gait analysis was made on a group of young healthy subjects and then, based on their kinematical parameters, a normative gait database of anatomical joint angles was created. Moreover, our database was compared with three different world available databases which were also compared each other. To compare individual kinematical parameters of all here included databases, a methodology based on testing of statistical hypotheses was used. Acquired results confirmed that the laboratories should spend some time to get their own normal human gait data to create own normative database in order to maximize the gait analysis objectivity rather than to use databases of another laboratories even if equipped with identical motion analysis system. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Statistics Research Letters Science and Engineering Publishing Company

Abstract

The human gait is uniquely characterized by its kinematics and kinetics. These characteristics are routinely used to analyse and evaluate both the normal and pathological gait. A lot of clinical studies, dealing with quantitative human gait analysis and published all around the world, use the normative gait databases to evaluate pathological gait, but only a few of them describe their background. However, this is an important factor as it makes the analysis objective and directly influences the interpretation of motion analysis results. There is also a lack of comparative studies that evaluate and compare such databases, acquired within different laboratories considering the age, typology and/or gender of included healthy/normal subjects. Therefore, the human gait analysis was made on a group of young healthy subjects and then, based on their kinematical parameters, a normative gait database of anatomical joint angles was created. Moreover, our database was compared with three different world available databases which were also compared each other. To compare individual kinematical parameters of all here included databases, a methodology based on testing of statistical hypotheses was used. Acquired results confirmed that the laboratories should spend some time to get their own normal human gait data to create own normative database in order to maximize the gait analysis objectivity rather than to use databases of another laboratories even if equipped with identical motion analysis system.
