Description

A functional exercise device for ankylosing spondylitis

technical field

The invention belongs to the field of medical devices, and in particular relates to a functional exercise device for ankylosing spondylitis.

Background technique

Ankylosing spondylitis is a systemic disease dominated by chronic inflammation of the axial joint. Inflammation of the sacroiliac joints and spinal attachment points is the main symptom. The etiology is not clear, there is a familial predisposition, and it is associated with HLA-B27. Certain microorganisms (such as Klebsiella) share antigens with susceptible individuals' own tissues, which can trigger abnormal immune responses. It often occurs in intervertebral disc fibrosis and its adjacent ligament calcification and bony rigidity, and is characterized by tendon, ligament, and bone enthesitis. Ankylosing spondylitis mostly occurs in young and middle-aged men. It can cause ankylosis and fibrosis of the spine, resulting in different degrees of eye, lung, muscle, and bone lesions. It is an autoimmune disease.

Ankylosing spondylitis is often manifested as pain and stiffness in the lower back and peripheral joints, limited chest expansion, which affects normal life, and has a high disability rate. Physiological function, delaying disease progression, reducing disability rate, and improving quality of life are the main goals of treatment and nursing. In the AS treatment recommendations of the ASAS/European League Against Rheumatism (EULAR) updated in 2016, it is emphasized that the optimal treatment strategy for AS is to carry out both drug treatment and non-drug treatment. Functional exercise is the cornerstone of non-drug therapy. Regular functional exercise can not only improve the mobility of the spine and joints, but also significantly improve the quality of life of patients and reduce the incidence of disability.

Patients with ankylosing spondylitis have obvious characteristics of rest pain and need functional exercise. Pay attention to maintaining a good standing and sitting posture in daily life, take deep breaths, expand the chest, and straighten the trunk regularly every day, so as to strengthen the flexibility of the lower back muscles and chest. Movements can soften joint stiffness, maintain extensibility, delay disease progression, and improve quality of life.

For office workers, there is a lack of exercise time, and it is difficult to maintain a good sitting posture. If there is a device that can help patients maintain a good sitting posture, it will not only save their exercise time, but also help patients with uninvolved cones and joints. function has better protection.
