Osteoarthritis self-adaptation heavy burden shock attenuation brace Technical Field The invention relates to the technical field of buffering and damping protective equipment, in particular to an adaptive load-bearing damping support for osteoarthritis. Background Osteoarthritis is a common degenerative joint disease in which the patient's articular cartilage becomes thin or even missing due to wear, resulting in a lack of effective cushioning of the bone ends during weight bearing movements of the joint, leading to pain, stiffness and limited movement. The shock-absorbing brace is used as an important non-operation auxiliary treatment means, and has the core function of providing external support and buffering for load-bearing joints such as knee joints or hip joints in the daily activities of walking, going up and down stairs and the like of patients. Such braces share the load applied to the diseased joint through a specific mechanical structure and absorb the impact force from the ground using an elastic material or a damping element, aiming at reducing abnormal pressure and friction between the articular surfaces, thereby alleviating pain, improving gait and possibly delaying further degenerative changes of the joint. However, most of the current shock absorbing brace techniques have significant limitations. The traditional brace adopts passive design more, and the supporting force and the shock attenuation effect that it provided often are fixed or preset, can not carry out dynamic adjustment according to user's real-time motion state and heavy burden intensity, and in walking cycle, from the high impact period of heel landing to the steady bearing in the middle stage of supporting, to the propulsion period that the tiptoe leaves the ground, the size and the direction of the force that the joint bore are rapid change, but traditional brace can't feel and adapt to this kind of change, and we propose an osteoarthritis self-adaptation heavy burden shock attenuation brace for this reason.
