PROBLEM TO BE SOLVED: To provide a gait analysis system by which motion of joints of lower limbs can be grasped and a walking state can be precisely evaluated without limitation of a measurement place.SOLUTION: Measurement sensors S1-S7 are respectively attached to a hip joint, knee joints, and foot joints of both feet of a pedestrian 1 so as to sandwich the joints, and measure angular velocities and accelerations of the pedestrian 1 during a walk to output measurement data. Each of the measurement sensors is stored in a storage pocket of a stretchable supporter or a stretchable band wound around a predetermined mounting position of the pedestrian 1 to be fixed. A gait analysis unit 12 is configured to: receive the measurement data output from the measurement sensors S1-S7 obtain joint angles of the hip joint, the knee joints, and the foot joints of the pedestrian 1 on the basis of the measurement data received and evaluate a walking state of the pedestrian 1 on the basis of the joint angles. In addition, the gait analysis unit 12 acquires the measurement data of each of the measurement sensors during standstill, and calculates each mounting tilt angle of the measurement sensors and an initial value of joint angle calculation.COPYRIGHT: (C)2015,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。各測定センサは、歩行者1の所定の取付位置に巻き付けて固定された伸縮性バンドまたは伸縮性サポーターの収納ポケットに収納されている。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、その関節角度に基づいて歩行者1の歩行状態の評価を行う。また、歩行解析部12は、静止時の各測定センサによる測定データを取得し、各測定センサの取り付け傾斜角および関節角度計算の初期値を計算する。【選択図】図1
