PROBLEM TO BE SOLVED: To provide a system and method for measuring walking function recovery state, capable of objectively evaluating the walking function by highly efficiently measuring the dorsiflexion and plantar flexion of a users leg during walking.SOLUTION: The measuring system of walking function recovery state includes: a leg orthosis comprising a support, and a leg holding part journaled to the lower end and swinging according to the dorsiflexion and plantar flexion operations of the leg a force sensor that is fitted to the support for detecting force applied to a part adjacent to a journal part according to the dorsiflexion and plantar flexion operations of the leg and a data analysis part that receives an output of the force sensor when the user performs a plurality of steps of walking operations to analyze a recovery state of the users walking function. The data analysis part defines timing when a sensor output X is maximized in a direction of the plantar flexion, as a sole grounding period of each step. The sensor output X is divided into respective step outputs Xn, with a period from one sole grounding period to a next sole grounding period defined as one period Tn of the walking. The system extracts data of specific phases d1-d2 during a period from a start point to a terminal point of each step output Xn.COPYRIGHT: (C)2015,JPO&INPIT【課題】歩行中の使用者の足の背屈や底屈の力を精度よく測定することができ、歩行機能の客観的な評価を可能にする歩行機能回復状況の測定システム及び測定方法を提供する。【解決手段】支柱とその下端部に軸着された足保持部とで構成され、足の背屈及び底屈動作に応じて足保持部が揺動する脚装具を備える。支柱に取り付けられ、足の背屈及び底屈動作に応じて軸着部近傍の部分に加わる力を検出する力センサ部を備える。複数歩の歩行動作を行ったときの力センサ部の出力を受け、使用者の歩行機能の回復状況の分析を行うデータ分析部を備える。データ分析部は、センサ出力Xが底屈方向に最大となるタイミングを各歩の足底接地期と認定する。一つの足底接地期から次の足底接地期までを歩行の1周期Tnとしてセンサ出力Xを各歩出力Xnに区分する。各歩出力Xnの始点から終点までの間の特定位相d1~d2のデータを抽出する。【選択図】図3
