Method and apparatus for analyzing the human postural control system

摘要: A method and an apparatus for analyzing the human postural control system includes computing mean square displacement of center pressure beneath a subject's feet vs. time interval. The result is plotted as stabilogram diffusion plot. plot, since reproducible, provides physiologically meaningful information from which assessment can be made. Brownian coefficient, indicative level stochastic activity pressure, calculated slope Also, log-log determination made to whether moving closer or away state relative equilibrium. Finally, short term open-loop scheme, operates before long closed-loop feedback scheme activates, studied when switches control.
