Research methods of gait kinematics and kinetics / 中国组织工程研究

ABSTRACT

BACKGROUND: Kinematics studies the movement of the objects using a method of geometry, with strength and quality not taken into consideration; Kinetics major studies the force of people acting on objects and its relationship with the movement of objects. OBJECTIVE: Through an introduction to kinematics and kinetics research equipment, this study was aimed to lead to the current status of kinematics and kinetics, to provide for experimental basis for the research of new equipment and gait experiments. METHODS: Taking "gait, kinetics, kinematics" in English for the search terms, Pubmed database (1999-01/2009-06)was retrieved. Taking "gait, kinematics, kinetics" in Chinese for the search terms, CNKI database (1999-01/2009-06) was searched. Literatures were limited to English and Chinese languages. The kinematics and kinetics research equipment regarding the gait were included, while other kinematics and kinetics experiments were excluded, also outdated and repetitive researches were excluded. RESULTS AND CONCLUSION: Totally 2 367 literature were obtained from the computer screen, and 33 documents of them were involved for analysis according to the inclusion and exclusion criteria, in case of gait analysis method, at home and abroad scholars have carried out extensive studies although the content are quite different, they used identical instruments and methods in the testing of gait, in spite of photography or video recording were applied to calculate and measure kinematic parameters, the force platform was all used to record kinetic parameters. Also there are a small number of studies using the distribution of plantar pressure to measure more precise foot-ground pressure distribution, and then proceed to a comprehensive statistical analysis. Kinetics and kinematics gait analysis is applied not only in rehabilitation medicine, but also widely in athletics sports and the related footwear manufactures, the commonly used method is the plane fixed-point photograph and force platform analysis.
