Gait phase detection apparatus with ankle joint angle self-rectification function

Abstract

The invention discloses a gait phase detection apparatus with ankle joint angle self-rectification function, which comprises a shank fixing mechanism, a ankle joint angle control mechanism, a ankle joint angle measuring mechanism and a thenar pressure measuring footwear. The invention can control ankle joint motor rotation angle according to thenar pressure signal, regulate ankle joint angle for foot drop patient in weight reduction walking training, prevent the damage to foot due to the towing and impacting caused by foot drop, and improve the dorsiflexion ability of foot drop patient; a pressure sensor and an angle sensor collects thenar pressure signal and ankle joint angle signal timely, an upper computer performs fuzzy logic algorithm to realize to detect gait phase smoothly and submissively. patient with walking ability defects or normal person with some degree of gait deformity can wear the invention while walking, detect the gait phase information in walking, estimate gait recovery degree scientifically, and optimize gait training strategy.

Description

A gait phase detection device with ankle joint angle self-correction function technical field The invention relates to a gait phase detection device with an ankle joint angle self-correction function, which belongs to the field of sports rehabilitation equipment. Background technique A group of near-perfect gaits allows humans to walk easily and for a long time. RanchoLosAmigosgaitanalysiscommittee divides human gait into 8 phases according to the joint angle and plantar force characteristics of human gait, and detects gait There have been many methods of phasing, but there are usually the following problems: the equipment is huge, cannot be worn for a long time, is expensive, and is not applicable to a wide range of people. Contents of the invention The purpose of the present invention is to design a gait phase detection device with simple structure, easy to use, wearable during walking training and self-correcting function of ankle joint angle. The gait phase detect...
