Embodiment Construction

[0029] The function of the orthotic designed in the present invention is to sense the stepping process of the patient's drooping foot, and during the lifting and falling of the drooping foot to the ground, stimulate the movement points of the muscles through the skin surface electrodes to make the dorsum of the foot and the calf stretch, In the process of dropping foot support, remove the electrode stimulation, so that the dorsum of the foot and the lower leg return to normal. The muscle movement mode is the same as that of a normal person when walking. In this way, the purpose of helping patients to walk is achieved. It adopts a new sensor device and a high-performance single-chip microcomputer as the core. The use of knee pads is convenient for patients, and it is placed on the lower part of the tibial tuberosity under the knee joint. When the patient is walking, the sensor device obtains the state of the patient's calf, and the single-chip microcomputer judges whether the...

Abstract

The invention discloses a wearable intelligent foot drop corrector and a correction method. The invention realizes correction by adopting a processing unit to receive and process the sensing signals returned by a tilt sensor and pressure sensors, convert the shank tilt angle signal returned by the tilt sensor into a value corresponding to the shank tilt angle, compare the processed shank tilt angle value and the preset tilt angle switching threshold, simultaneously monitor whether the pressure signals returned by the pressure sensors arranged at the heels of the user bear the weight pressure of the user in real time and send an electric pulse stimulation signal to a simulation circuit to trigger a simulating electrode to generate simulated current when the measured value of the tilt sensor reaches or is more than the opening threshold and the pressure sensors arranged at the heels of the user bear the weight pressure of the user. The corrector has the characteristics of simple structure, convenient use, obvious effect and low cost and is suitable for being popularized in the field of foot drop treatment.

Description

technical field [0001] The invention relates to a wearable intelligent foot drop corrector and a correction method. Background technique [0002] After many patients suffer from stroke or other diseases, nerve conduction is blocked and foot drop occurs. Foot drop is one of the most common disorders of the lower leg. In this case, the patient cannot normally flex the ankle joint through the muscles, and the foot cannot be lifted off the ground when swinging or walking, but drags on the ground, making walking difficult and prone to falls, endangering the patient. At present, the commonly used treatment methods for foot drop include physical therapy (foot warming therapy, rehabilitation stretching, massage, etc.), drug therapy (oral antispasmodic drugs or injection of botulinum toxin, etc.) or surgical treatment. For those who have completed neurological treatment, orthotic treatment is recommended. Most of the current foot drop correctors use mechanical methods (mechanical ...
