Abstract
For decades, the gravitational body sway test (GBST) has been used for analysis of static body equilibrium in terms of postural righting function with eyes open and closed. Despite development of a variety of analytical methods for this, it appeared necessary to evaluate the body equilibrium functions during dynamic postural control since the function and dysfunction of the equilibrium may be better revealed during dynamic body movements. Therefore, we developed a new system which can interpret dynamic postural control in relation to visually guided active movements.
In essence, this system which tests the ability to track a computer-controlled moving target on a video screen by the gravitational center of the body simultaneously displayed on the same screen enables us to evaluate dynamic postural control. Our "Body Tracking Test (BTT)" interprets the subject's ability to follow the moving visual target by volitionally shifting the body's center of gravity. Thus, the system works with dynamic gravitational bodily equilibrium cued by a visual moving target in concert with the subject's attention/intention. With this system, we are now beginning to understand postural control in the dynamic sphere, and hence to put together the concepts of static and dynamic equilibrium in relation to motor development, motor skills, sports, disease, and rehabilitation.
