Description

Technical Field

[0001] The invention relates to the field of foot and ankle orthotics, in particular to a foot and ankle orthotics and functional training device. Background Art

[0002] Stroke is one of the diseases with a high disability rate. It affects the patient's cognition, swallowing function and motor function to varying degrees, greatly reducing the patient's ability to participate in society. Stroke rehabilitation is a complex process that often requires the coordination of multiple disciplines and professions. In order to achieve a better rehabilitation effect, it is necessary to evaluate the patient's problems from multiple aspects and angles and carry out targeted treatment. Restoring walking function is one of the most urgent wishes of stroke patients. Walking function is an important part of daily transfer. Walking can make the patient's range of activities no longer limited, and restore the "social person" with social attributes. However, restoring high-quality walking function is not an easy task, because walking function involves the independence and coordination of the hip, knee and ankle, and none of them can be missing. If the function of one aspect is limited, the function of the entire lower limb will be affected. The most obvious and common problems of stroke patients are foot drop and limited foot function. The main pattern of lower limb extensor joint movement spasticity in stroke patients is hip extension, knee extension, ankle plantar flexion and inversion. The ankle joint has the greatest impact on gait. Ankle plantar flexion and inversion seriously affect the patient's foot clearance function, that is, the ankle joint cannot be lifted off the ground, and it is easy to fall when walking. In order to successfully complete the leg lifting action, the patient's general compensatory measure is to lift the hip and step, forming a circular gait. The circular gait is inefficient, high in energy consumption, and puts a large load on the joints. Therefore, how to improve the ankle function is the clinical recovery of walking function. There are key points and difficulties in treating plantar flexion and inversion of the ankle joint. There are related treatment measures, such as the use of orthoses and the application of functional electrical stimulation. However, both methods have certain limitations and shortcomings. There are many types of orthoses, which are divided into day-use and night-use, therapeutic and functional types, which make the selection difficult. Orthoses are tools for fixing and correcting alignment, and lack the function of active training. Functional electrical stimulation requires special instruments or equipment. Although there are portable functional electrical stimulators now, they are still relatively expensive. In addition, functional electrical stimulation is only suitable for patients in the late stages of rehabilitation.

[0003] Chinese utility model patent application number 202321883635.1 discloses an ankle-foot orthosis equipped with a massage component. On the basis of the original ankle-foot orthosis, a leg massage component, an ankle massage component and a foot massage component are added, and a massage function is added to the ankle-foot orthosis. It can massage the user's legs, ankles and feet, promote blood circulation, facilitate injury recovery, and improve the user's comfort; Chinese utility model patent application number 202321755249.4 discloses an ankle-foot orthosis for stroke patients, and the foot component can be used The hinge of the movable hinge is that the axis swings in the sagittal plane, which solves the technical problem in the prior art that rehabilitation exercise activities are affected by unreasonable structure; the Chinese invention patent with application number 202410046562.3 discloses an adjustable ankle-foot orthosis, which can adjust the foot support structure according to the foot size of different people, and at the same time can appropriately adjust the ankle deformities caused by accidental fractures or other sequelae of other diseases such as inversion of foot, valgus foot, high arch foot, reverse instep, heel not touching the ground, scissors step, etc.; and further has an airbag to wrap the ankle, thereby protecting the ankle.

[0004] Current situation and difficulties: 1. Traditional ankle-foot orthoses focus on the correction of the ankle joint and ignore the problem of forefoot inversion. If the inversion of the forefoot is not solved, the lateral side of the fifth metatarsal (fifth metatarsophalangeal joint) will aggravate the inversion symptoms and even cause pain when landing for the first time. 2. The fixation belt cannot be inflated, and the pressure generated is relatively high. Long-term compression can cause the skin of the foot to become red and painful. 3. The flexion problem of the toes is less considered, and the skin on the back of the foot is under long-term pressure, which is prone to pressure sores. 4. There is no other auxiliary training structure at the bottom of the traditional ankle-foot orthosis, the training intensity cannot be adjusted, lacks fun, and patient participation is not high. Summary of the invention
