Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, and in particular to a portable intelligent orthopedic device for improving spinal mobility in AS patients. Background Technology

[0002] Ankylosing spondylitis (AS) is a chronic inflammatory disease that primarily affects the spine and sacroiliac joints, eventually leading to joint ankylosis and spinal deformities. Its global incidence is approximately 0.1%-1.4%, and it commonly affects young adult men. The average age of diagnosis is 25-30 years. Patients gradually lose spinal mobility, and hip joint ankylosis leads to walking difficulties, resulting in a significant decline in patient quality of life. Rehabilitation training can slow disease progression.

[0003] Currently, rehabilitation devices for AS patients are mainly divided into static orthotics and dynamic training equipment, but both have significant drawbacks: chest fixation leads to a 15%-30% decrease in vital capacity, and long-term wear causes muscle atrophy; patients wear them for less than 2 hours a day, far less than the recommended 6 hours or more; patients cannot perceive minor postural errors, and compensatory muscle exertion accounts for more than 60%; sudden stretching can easily lead to ligament strain, and 30% of patients need to be hospitalized due to improper training.

[0004] There are over 5 million AS patients, but rehabilitation services cover less than 20% of them. Existing rehabilitation devices for AS patients are mainly divided into static orthotics and dynamic training equipment. Long-term wear can easily lead to muscle atrophy, while short-term wear makes it impossible for patients to perceive minor postural errors. Sudden stretching can easily cause ligament strains, resulting in poor safety. Traditional methods (such as the "Little Swallow" exercise and plank exercises) have limited effectiveness for late-stage patients and lack personalized guidance.

[0005] Therefore, it is necessary to provide a portable intelligent orthopedic device that improves spinal mobility in AS patients to solve the above-mentioned technical problems. Utility Model Content
