PROBLEM TO BE SOLVED: To provide a gait analysis system and a gait analysis method allowing grasping of motions of joints of legs and more detailed evaluation of a walking state without limiting a measuring place.SOLUTION: Respective measuring sensors S1-S7 are attached to sandwich the hip joints, knee joints and leg joints of both legs of a walker 1, and an angular velocity and an acceleration in walking of the walker are measured to output measurement data. A gait analysis unit 12 receives the measurement data output from the measuring sensors S1-S7, determines the joint angles of the hip joints, knee joints and leg joints of the walker 1 based on the received measurement data, and also determines other gait information. The gait analysis unit 12 evaluates the walking state of the walker 1 based on a relation between the joint angles and other gait information.COPYRIGHT: (C)2012,JPO&INPIT【課題】測定場所の制限がなく、下肢の関節の動作を把握可能で、歩行状態をより細かく評価することができる歩行解析システムおよび歩行解析方法を提供する。【解決手段】各測定センサS1~S7が、歩行者1の両足の股関節、膝関節および足関節を挟むよう取り付けられ、歩行者1の歩行時の角速度および加速度を測定して測定データを出力する。歩行解析部12が、測定センサS1~S7から出力された測定データを受信し、受信した測定データに基づいて、歩行者1の股関節、膝関節および足関節の関節角度を求め、さらに、それ以外の歩行情報も求める。歩行解析部12は、関節角度とそれ以外の歩行情報との関係に基づいて、歩行者1の歩行状態の評価を行う。【選択図】図1
