Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a finger function training device for periarthritis of shoulder and rheumatoid arthritis. Background Art

[0002] Frozen shoulder, whose full name is periarthritis of the shoulder, is called "leaky shoulder", "frozen shoulder" and "fifty shoulder" in traditional Chinese medicine. It is a common and frequently occurring disease characterized by shoulder joint pain, which first presents as paroxysmal soreness and is followed by movement disorders. Rheumatoid arthritis is a common acute or chronic connective tissue inflammation, which is clinically characterized by migratory soreness, heaviness and pain in the joints and muscles. It is an allergic disease and one of the main manifestations of rheumatic fever. It often presents with acute fever and joint pain.

[0003] Patients with frozen shoulder and rheumatoid arthritis often experience pain in their arms and fingers, as well as stiffness and difficulty bending their fingers. This not only impacts their daily lives but also reduces their quality of life. Therefore, proper finger exercises are crucial for these patients. These exercises can improve blood circulation in the fingers and enhance joint flexibility, thereby alleviating pain and improving joint function.

[0004] However, traditional exercise methods often fail to achieve the desired effect, especially for patients with limited finger joint mobility, who need a special exercise device to assist them in functional exercise. Therefore, a finger function exercise device for patients with periarthritis of shoulder and rheumatoid arthritis has emerged. Summary of the Invention
