Problems solved by technology

[0002] A group of near-perfect gaits that allow humans to walk easily and for a long time. The Rancho Los Amigos gait analysis committee divides human gaits into 8 according to the joint angles and plantar force characteristics of human gaits. Phase, there are many methods for detecting gait phase, but there are usually the following problems: the equipment is huge, cannot be worn for a long time, the cost is high, and the applicable population is not wide

Embodiment Construction

[0016] Further illustrate the present invention below in conjunction with accompanying drawing.

[0017] refer to figure 1 , the gait phase detection device with ankle joint angle self-correction function of the present invention, comprises calf fixation mechanism, ankle joint angle control mechanism, ankle joint angle measurement mechanism and plantar pressure measurement mechanism:

[0018] The calf fixing mechanism comprises a length-adjustable calf strap 1 and two inner and outer calf splints 16-1, 16-2. One end of the calf strap 1 is fixed to the outside of a calf splint, and the other end is a length-adjustable free end. Elastic pads 17 are respectively adhered to the inner surfaces of the two calf splints, so that the calf straps are used to tighten the calf so that the user feels soft and comfortable.

[0019] The ankle joint angle control mechanism includes a motor 2, an I-shaped connector 3, a first rotating part 4 of the ankle joint, and a height-adjustable support...

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

technical field [0001] 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 [0002] A group of near-perfect gaits that allow humans to walk easily and for a long time. The Rancho Los Amigos gait analysis committee divides human gaits into 8 according to the joint angles and plantar force characteristics of human gaits. Phase, there are many methods for detecting gait phase, but there are usually the following problems: the equipment is huge, cannot be worn for a long time, the cost is high, and the applicable population is not wide. Contents of the invention [0003] 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. [0004] The gait phase detection device with ankle joint angle self-corr...
