Technical Field
The invention relates to a medical auxiliary instrument, in particular to a biomechanics-based ankle injury rehabilitation device.
Background
The ankle is a Chinese word, which means the protrusion of the left side and the right side of the part between the lower leg and the foot, commonly called as the ankle, the foot is the second heart of the human body, the ankle is the important gateway for the blood flow of the left foot and the right foot, the blood circulation of the lower half of the human body is smooth or not, the influence on the whole qi and blood circulation is great, the ankle is the important part for the blood flow of the left foot and the right foot, if the ankle is soft and elastic, the venous blood returning to the heart can smoothly pass through the ankle; if the ankles are stiff and aged, the blood stagnates around the ankles, and the normal blood circulation is affected.
The ankle is a vital position on the human body, and ankle sprain is the most common athletic injury, accounting for about 40% of all athletic injuries. The ankle joint comprises shin bone fibula distal end and talus, constitutes the ankle cave by outer ankle and shin bone trailing edge, and the saddle type articular surface above the talus is located the ankle cave, and is narrow behind the preceding wide of saddle type articular surface of talus, and wide department gets into the ankle cave during dorsum extension, and narrow portion gets into the ankle cave when plantarflexion, so the ankle joint is slightly not hard up in plantarflexion position, and the performance of ankle damage does respectively: the ankle part is gorged and swollen, inconvenient to move, accompanied by pain and even the rupture of the ligament.
In the ankle injury rehabilitation process, if the ankle part does not move for a long time and the ankle injury part is not easy to repair, the related and targeted daily training process is needed, for example, the rehabilitation training of jogging, the ankle part of the human body is the main stress part, and during the movement of the human body, because the forces are mutual, the ground can apply the mutual acting force in a certain vector direction to feed back to the feet of the human body during the motion process of the human body, for the person with ankle injury and in rehabilitation period, the interaction force generated in the process can directly act on the ankle of the person, and because the magnitude of the interaction force in the process can not be directly controlled, the excessive or insufficient interaction force can cause extra burden to the ankle, is not favorable for the rehabilitation efficiency and is accompanied with severe pain, therefore, to solve such problems, we propose a biomechanically based ankle injury rehabilitation device.
