PROBLEM TO BE SOLVED: To provide a synthetic diagnostic method and apparatus from many fields, for guessing a knee joint function and an attitude control function in a situation more equivalent to a daily action, wherein knee joint information and attitude information by exercise including a knee in a state of imposing weight are linked.SOLUTION: This dynamic knee joint composite diagnostic apparatus includes: a head position displacement sensor 1 measuring three-dimensional displacement of a head a knee displacement sensor 2 measuring three-dimensional displacement of the knee a knee angle sensor 3 measuring an angle of the knee and an information processor 4 processing information measured from the head position displacement sensor 1, the knee displacement sensor 2, and the knee angle sensor 3. The displacement measurement in a rising position wherein the weight is imposed, and in time of bending and stretching exercise or the like of the knee, and the measurement information of the angle of the knee joint and rock of the knee are processed in the information processor 4, and the knee joint is synthetically diagnosed.COPYRIGHT: (C)2012,JPO&INPIT【課題】体重を負荷した状態で膝を含んだ運動による膝関節情報と姿勢情報をリンクさせた、より日常行動に準じた状況での膝関節機能と姿勢制御機能を推測する多方面からの総合的診断法と装置を提供することを可能とする。【解決手段】頭部の3次元変位を計測する頭位変位感知器1と、膝の3次元変位を計測する膝変位感知器2と、膝の角度を計測する膝角度感知器3と、前記頭位変位感知器1、膝変位感知器2、膝角度感知器3からそれぞれ計測される情報を処理する情報処理装置4とからなり、体重を負荷した起立位、及び膝の屈伸運動等時の変位計測と、膝関節の角度と膝のゆれの計測情報を情報処理装置4で処理し、膝関節を総合的に診断することを特徴とする。【選択図】 図1
