Description

Technical Field

[0001] The present invention belongs to the technical field of data processing systems, and particularly relates to an Achilles tendon rupture risk assessment system. Background Art

[0002] The Achilles tendon is an important structure connecting the heel and calf muscles, and its main function is to assist in walking, running, and jumping. When the Achilles tendon is overstretched or torn, it will cause Achilles tendon rupture. Achilles tendon rupture refers to the tearing injury of the Achilles tendon caused by direct or indirect violence, resulting in partial or complete rupture of the Achilles tendon. The common clinical diagnostic bases for Achilles tendon rupture are as follows: The patient has a clear history of sports injury or trauma, and has typical symptoms such as heel bleeding, swelling, pain, and movement disorders. During physical examination, a positive Thompson sign or a positive O`Brien test can confirm the diagnosis; X-ray shows soft tissue calcification or thickening in the Achilles tendon area; ultrasound examination finding a rupture in the heel can confirm the diagnosis; MRI finding an Achilles tendon rupture can also confirm the diagnosis.

[0003] To prevent Achilles tendon rupture, the primary task is to evaluate the risk of Achilles tendon rupture and screen out high-risk populations of Achilles tendon rupture at an early stage, so as to guide whether high-risk populations can engage in various light and heavy physical labors, including daily activities such as grocery shopping, traveling, exercising, dancing, etc., and their original jobs. For professional athletes, it can also be used to guide the participation degree of various occupational physical exercises, so as to reduce the incidence of Achilles tendon rupture and reduce the medical burden. Some commonly used clinical scales such as the Achilles Tendon rupture score (ATRS) are used to evaluate the risk of Achilles tendon rupture in patients according to multiple indicators such as age, gender, performance during exercise and activities. Through this tool, the risk of an individual can be quantified, and then targeted preventive measures can be taken. The existing commonly used clinical Achilles tendon rupture score ATRS is mostly based on the self-report of patients, with strong subjectivity, no objective examination indicators are included, and there are large differences in the evaluation results of different doctors; risk factors for rupture caused by chronic diseases such as diabetes and hyperlipidemia are not considered.

[0004] Therefore, there is an urgent need in the art to develop an Achilles tendon rupture risk assessment system that can incorporate more risk factors, has a more comprehensive evaluation, and can evaluate the risk of Achilles tendon rupture in the general population at an early stage and screen out high-risk populations of Achilles tendon rupture at an early stage. Summary of the Invention

[0005] In order to solve the problem of the above-mentioned inability to accurately evaluate the risk of Achilles tendon rupture at an early stage in the prior art, the present invention provides an Achilles tendon rupture risk assessment system, which can relatively accurately and effectively assist various risk populations of Achilles tendon rupture in early screening and early prevention.
