Biomechanical Investigation On Gait Initiation And Gait Termination

Walking is an important functional exercise in our daily life. The relationship between external features of human movement and the body's neuromuscular system during the walking is concerned. The gait analysis, which studies the characteristics of various groups has developed into a new branch of the biomechanics.With the application of gait analysis in clinical rehabilitation, robot, biometric identification and so on, the aspect of it's research is gradually refined. It's used to divided the gait into four processes as follows, gait initiation, steady-state gait, turning and gait termination. All of this is very important for a successful walking. We can get a large number of information from this simple process. And this information is helpful for us to explain some natural phenomena. For instance, what will happen of the gait characteristics with age? Why elder does has more falling risk the young, What should we do to the movement disorders in their rehabilitation process, and so on. The results of gait analysis will be made to answer these questions.Gait analysis is carried out earlier in foreign country. Up to now, it has been development systematic and comprehensive. The four processes of gait in children, young and elder have been studied. And the kinematics and dynamics characteristics in those processes are described.However, gait analysis is started late in China. In clinical practice, the doctor mostly evaluation the gait with visual experience. Gait analysis is lack of assessment criteria to meet Chinese population. And most of the studies are related pathology description and a few normal human gait studies are limited to steady-state gait.The main purpose of this paper is investigate the gait initiation and gait termination in Chinese population. And we've obtained some kinematics and kinetics parameters, what's more, different of gait termination between young and elder are studied also. The results of this study will be helpful for plastic surgery, rehabilitation of lower limb and the reduction of fall risk in elder.
