Description

An ankle joint function recovery training device

technical field

The utility model relates to the technical field of medical rehabilitation equipment, in particular to an ankle joint function recovery training device.

Background technique

The ankle joint is composed of the articular surface of the lower end of the tibia and fibula and the talus trochlear, so it is also called the talus calf joint. The trochlear joint is wide in front and narrow in the back. When the foot is dorsiflexed, the wider anterior part enters the socket, and the joint is stable; but when the foot is in plantar flexion, such as when walking downhill, the narrower posterior part of the trochlear enters the socket, and the ankle joint is loose and able to function. When doing lateral movement, the ankle joint is prone to sprain, and varus injury is the most common. Because the lateral malleolus is longer and lower than the medial malleolus, it can prevent the excessive valgus of the talus and the limited range of motion of the ankle joint. Then remove the cast. In the early stage after the ankle surgery, many patients will be immobilized in a plaster cast for a period of time, so it is inevitable to practice the range of motion.
