| Outline of Final Research Achievements |
To have better understanding of early diagnosis of vestibular disorder, we have developed a method of measuring body sway by using a 3-dimensional electromagnetic tracker (MoCap) with comparison of force plate (FP).
As a result, the Romberg ratio of the elder and vestibular disorder subjects higher than that of younger subjects. Both inputs of vestibular and somatic sensory functioned efficiently in younger subjects compared to those of elder and vestibular disorder subjects. These implied that not only the vestibular input, but somatic input in elder and vestibular groups also depleted that caused difficulty in maintaining posture. Meanwhile, the enveloped area of elder subjects were significantly increased under eyes-closed condition when measured by MoCap but not FP, we conclude that MoCap is capable to measure changes in different point of the body and it may serve as a better test tool in recording and detecting central and peripheral disorders of individuals.
