Description
Technical Field
The utility model relates to the field of orthopaedics equipment, in particular to leg exercise auxiliary equipment.
Background
Orthoses are regularly eliminated due to the tendency of the wearer to rely excessively on the orthoses to weaken the muscles. This occurs when the stent fixes the target disease (e.g., osteoarthritis) to be treated by delaying final healing. The wearer may become more dependent on the support to stabilize the joint than on the actual muscles.
Osteoarthritis is a progressive degenerative joint disease, often resulting in disability and loss of joint function. Osteoarthritis of the knee can be debilitating because daily activities (e.g., going up and down stairs or assorted to rest) can stress the knee. Osteoarthritis causes the articular cartilage to gradually fracture. As the disease progresses and cartilage disappears, the bones rub against each other and cause pain.
Knee osteoarthritis is a chronic degenerative disease that gradually worsens. In the early stages of development, people often reduce activity or work due to discomfort and pain. Advanced knee osteoarthritis is associated with pain, stiffness and inflammation.
In a healthy knee, cartilage covers the ends of bones and prevents them from rubbing against each other. When the cartilage surface breaks, small cracks and dents may be formed. In mild cases of osteoarthritis, the knee may show signs of varus misalignment. Over time, various portions of the cartilage wear away, thereby reducing flexibility and increasing the likelihood of damage from daily activities. The lubricating fluid (synovial fluid) breaks down and becomes ineffective, while cracks and pits continue to appear in the cartilage. As the knee degenerates, the legs bend into an arch.
In severe osteoarthritis, the bone is not protected as most of the cartilage is worn away, resulting in the bones being stinged towards each other as they move. Pain and damage may be caused by small fragments of cartilage falling off and possibly floating around the joint. Externally, severe bending of the leg relative to the thigh often occurs.
As is well known, quadriceps femoris is a muscle of the anterior surface of the thigh, comprising four independent muscle groups: rectus femoris, lateral rectus femoris, medial rectus femoris and medial rectus femoris. The weakness of quadriceps is usually associated with osteoarthritis of the knee, and is generally thought to be due to atrophic atrophy secondary to the pain of the affected joint. Quadriceps weakness is a major risk factor for knee pain, disability and progression of joint injury in knee osteoarthritis patients.
Studies have shown that regular exercise, which is moderately exercised, is also beneficial to arthritic patients. It helps to maintain the flexibility of the joint and increase the range of motion. On one exercise, the body releases endorphins, which are natural analgesics. Thus, not only is it advantageous to use and strengthen muscles, but moderate use of muscles can improve the condition of osteoarthritis patients.
Therefore, there is an urgent need to provide a solution for assisting the simple exercise of the knee arthritis patient to solve the above-mentioned technical problems.
