Patent ID: 8574173

Claim:
A motor function estimating system comprising: a memory unit for storing waveform data with reference to a time of a fingers tapping motion; the waveform data is obtained by a motion sensor attached to a subject person who does the fingers tapping motion that is repetition of an opening and closing motion of two fingers of one hand; an analyzing section for analyzing the waveform data stored in the memory unit; and a display unit for displaying an analysis result by the analyzing section; wherein the analyzing section comprises: a motion waveform generating section for making a motion waveform corresponding to the waveform data stored in the memory unit; a characteristics generating section for making plural characteristics that represent features of the fingers tapping motion, based on the motion waveform; an age-normalized characteristics generating section for creating each of plural age-normalalized characteristics by calculation a regression line or a regression curve that represents a distribution tendency depending on age of each of the plural characteristics and calculating a difference between each of the plural characteristics and a value of the age on the regression line or the regression curve; a motion disorder synthesis value generating section for creating a motion disorder synthesis value that represents a degree of motion disorder of the subject person by comparing the plural age-normalized characteristics made by the age-normalized characteristics generating section with corresponding characteristics of healthy persons previously stored in the memory unit and synthesizing the plural characteristics.
