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 user's 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 user's 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. |
