Recovered seat of knee joint individuation function

Technical Field

The utility model relates to the field of machinary, specifically, relate to seat.

Background

The artificial total knee joint replacement is an operation with a very definite curative effect, but the due effect of the operation cannot be achieved only by supporting the successful operation on the operation technology without effective rehabilitation training. For total knee replacement, functional exercise and surgery have the same important role, which is related to the function and mobility of the knee in the future. The knee joint functional exercise is most important in quadriceps femoris strength training and knee joint flexion and extension exercise. Traditionally, doctors would verbally inform the patient after surgery how to perform knee rehabilitation exercises, such as raising the lower limbs with straight legs to exercise the muscle strength of the lower limbs, flexing the knee joints to exercise the joint mobility, etc. However, there are the following problems: firstly, the process of exercising quadriceps femoris by raising the lower limbs by straight legs, the patient often can not master the action to be led, and the exercise effect is difficult to achieve. In the knee joint flexion and extension exercise process, the judgment of the patient and the doctor on the knee joint flexion angle is too subjective, and more deviation exists between the patient and the actual knee joint flexion angle, so that the preset exercise target is difficult to realize.
