Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to a rehabilitation training device for exercising lower limb muscles of patients with knee osteoarthritis. Background Art

[0002] Knee osteoarthritis (KOA) is one of the most common degenerative diseases causing disability in the elderly. A survey showed that by the end of 2017, the prevalence of KOA in China was as high as 18%, with a prevalence of 19% in women and 11% in men, with an overall trend of significantly higher prevalence in women than in men. The total number of patients with KOA exceeds 200 million. The pathogenesis of KOA involves multiple fields, including biochemistry and biomechanics. Currently, clinical treatments for KOA mainly include basic care (health education, exercise therapy, physical therapy, and mobility support), pharmacotherapy (analgesics, intra-articular injections, slow-acting medications to relieve arthritis symptoms, antianxiety medications, and traditional Chinese medicines), restorative therapy (joint debridement, cartilage repair, high tibial osteotomy, and fibular subsidence), and reconstructive therapy (joint replacement). Medication requires long-term administration, may have significant side effects, and patient compliance is poor. Intra-articular injections of corticosteroids or sodium hyaluronate can improve KOA symptoms in the short term, but long-term efficacy is unsatisfactory. Both restorative and reconstructive therapies are surgical procedures, which carry associated complications and are suitable for patients with mid- to late-stage KOA.

[0003] In the prior art, rehabilitation training devices for lower limb muscle training of patients with knee osteoarthritis are large in size, inconvenient to carry, and have high training intensity. The high-load training in the early stage affects the patient's recovery. Therefore, we propose a rehabilitation training device for lower limb muscle training of patients with knee osteoarthritis.
