Outline of Final Research Achievements

During quiet standing, human body joints show flexible and coordinated movement. In this study, we analyzed experimental postural sway data obtained from healthy young subject, and showed that the flexible and coordinated joint movement are based on skillful usage of intrinsic property of human body. We also measured Center of Pressure (CoP) during quiet stance from patients with Parkinson's disease and age matched healthy elderly. We performed a linear discriminant analysis and showed that CoP variations in Parkinson's disease patients and those in healthy elderly could be well distinguished with an accuracy of about 90%. Major factors responsible for the discrimination were associated with power at frequency band, and our results suggested that diminution of flexible anti-phase coordination leads postural instability in Parkinson's disease patients.
