Method and apparatus for determining skeletal muscle cross-sectional area calculation model of subject based on demographic element and kinematic element
A method and apparatus for determining a subject's skeletal muscle cross-sectional area calculation model based on demographic factors and kinematic factors are disclosed. The method comprises: dividing a population of subjects into a modeling population for determining the calculation model and a verification population for verifying the obtained calculation model； Calculating a skeletal muscle cross-sectional area of subjects belonging to the population； Determining a demographic factor of the subject belonging to the modeling population and applying a regression technique to the determined demographic factor to obtain a demographic model for calculating the skeletal muscle cross-sectional area of the subject from the demographic factor ； Determining a kinematic element of the subject belonging to the modeling population and applying a regression analysis technique to the determined kinematic element to obtain a kinematic model for calculating the skeletal muscle cross-sectional area of the subject from the kinematic element； Estimating skeletal muscle cross-sectional area by applying a demographic factor and a kinematic factor of the subject belonging to the verification population to the obtained demographic model and kinematic model； And verifying the demographic model and the kinematic model by comparing the estimated skeletal muscle cross-sectional area with the calculated skeletal muscle cross-sectional area. Demographic and kinematic models can be defined to predict the mean muscle values of a group of subjects sharing similar features with demographic information obtainable with the present invention.인구통계학적 요소 및 운동학적 요소를 기반으로 피험자의 골격근 단면적 산출 모델을 결정하는 방법 및 장치가 개시된다. 이러한 방법은, 피험자의 모집단을 상기 산출 모델을 결정하기 위한 모델링 모집단 및 획득된 산출 모델을 검증하기 위한 검증 모집단으로 분할하는 단계； 상기 모집단에 속하는 피험자들의 골격근 단면적을 계산하는 단계； 상기 모델링 모집단에 속한 피험자의 인구통계학적 요소를 결정하고, 결정된 인구통계학적 요소에 회귀분석 기법을 적용하여 상기 인구통계학적 요소로부터 상기 피험자들의 골격근 단면적을 산출하기 위한 인구통계학적 모델을 획득하는 단계； 상기 모델링 모집단에 속한 피험자의 운동학적 요소를 결정하고, 결정된 운동학적 요소에
