METHOD OF DIFFERENTIAL DIAGNOSTICS OF ATAXIA Russian patent published in 2005 - IPC

FIELD: medicine; neurology.

SUBSTANCE: testing is conducted onto stable-graphic platform when patient does exercises to keep his/her vertical position. During doing any exercise, the trajectory of motion of center of body's pressure onto platform is measured and fixed. Statokinegram received then is subject to analysis by means of vector analysis and normalized area of statokinegram is measured as well as average radius of body's inclination, quality factor of equilibrium function in form of coefficient λ of exponential dependence f(n)=I-e^λn, relative frequency of vertexes of vectors at concentric areas of statokinegram being equal to each other, increasing area of vector, factor of sharp change in vector of motion, average linear and angular speeds and accelerations and factors of asymmetry of angular speed and acceleration. Then the kind of ataxia is diagnosed by using statistic method of classification trees.

EFFECT: wider range of diagnostic aids for determining kind of ataxia.
