[0001] This invention relates to the field of medical protection technology for the hip and knee joints, and more particularly to a multifunctional medical brace for the hip and knee joints. Background Technology

[0002] The hip and knee joints play a vital role in human movement and daily life; however, these joints are also susceptible to injury or disease, such as hip arthritis, knee synovitis, and meniscus tears. Currently, the market offers a wide variety of medical braces for the hip and knee joints, but most offer only a single function. Common knee and hip braces primarily provide simple cushioning and warmth, which are insufficient for patients requiring rehabilitation training assistance, precise pressure adjustment, and real-time joint monitoring. For example, during rehabilitation training, patients need braces that provide appropriate support to assist joint movement and reduce the burden on the joints. Furthermore, the support position and area required by different patients need to be adjusted accordingly. Therefore, developing a multi-functional medical brace for the hip and knee joints is of significant practical importance. Summary of the Invention
