Gait detection device of foot drop corrector

Abstract

The invention relates to a gait detection device of a foot drop corrector. The device is provided with an insole and is characterized in that the insole is provided with a circuit module; the circuit module comprises a flexible circuit board and a circuit protection board; and sensors, a microprocessor, a wireless communication circuit and a battery are distributed and installed on the flexible circuit board. Compared with the prior art, the device has the following beneficial effects: the device has reasonable structure, realizes direct connection between the microprocessor and the wireless communication circuit as well as the sensors and overcomes the defect of generation of the signals and the contact fault of the treatment device; the integral structure brings convenience for the patients; and the defect that errors between the signals of the pressure sensors and the actual gait are generated because the sick foots always fall to the ground unstably when contacting the ground can be overcome by using the flexible steel board as the circuit protection board.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a gait detection device for a foot drop corrector. The device is used to detect the gait and transmits the output to an electric stimulation device for a foot drop corrector. Background technique [0002] Stroke, traumatic brain injury, spinal cord injury, and multiple sclerosis and other central nervous system diseases often cause foot drop. The patient showed that he could not dorsiflex the foot, and when walking, he either dragged the diseased foot or lifted the lower limb of the diseased side higher, so the gait was slow, abnormal, poor in stability, and unable to walk for a long time. This abnormal gait further causes hip, back, and knee joint injuries, seriously affecting the patient's daily life. [0003] The traditional treatment for foot drop is to use a mechanical foot support to fix the foot and lower leg at a vertical angle, mechanically preventing the fo...

Problems solved by technology

However, the pressure sensor of the current wireless gait detection device is placed under the patient's foot, and the signal processing and transmission device is placed on the upper of the shoe. It is necessary to connect the sensor to the signal processing and transmission device through an interface, which increases the contact failure between the signal and the processing device. The emergence also brings troubles to patients wearing

And because the pressure sensor is placed under the patient's affected foot, when the affected foot is in contact with the ground, it often falls to the ground, so the signal of the pressure sensor will have an error with the actual gait
