Population aging is a serious social problem commonly faced by countries in the world today, and China is no exception. The 2002 population sampling survey shows that: the population over 65 years old in China accounts for 7% of the total population, namely the senile population structure type, which means that China has started to take a senile society. The cerebral apoplexy is a common disease which is harmful to life and health of middle-aged and elderly people, the annual incidence rate of the cerebral apoplexy in urban and rural areas in China is 200/10 ten thousand, the annual death rate is 80-120/10 ten thousand, more than 70% of survivors have different degrees of dysfunction, wherein 40% of survivors are serious disabilities, and the recurrence rate of the cerebral apoplexy reaches 40%.

In the recovery process of a cerebral apoplexy hemiplegia patient, abnormal walking patterns can occur in the whole walking cycle due to abnormal extensor coordination movement patterns of lower limbs of the patient. In the walking cycle, the hemiplegia patient has abnormal walking modes such as a circle drawing gait and the like due to the overstretching state of the knee joint and the compensatory lifting of the pelvis of the patient side caused by the quadriceps of the lower limb of the patient side. To improve the abnormal walking pattern of the patient, it is necessary to train the control ability of the affected knee joint, and the patient must break the extensor cooperative pattern of the affected lower limb to autonomously complete the flexion and extension knee control, so as to improve the abnormal walking pattern. However, in the rehabilitation training process, it is found that due to the cooperation mode of extensor muscles of lower limbs, the quadriceps spasm of lower limbs is affected, and many patients can hardly autonomously complete the knee bending action.

Therefore, how to help patients improve abnormal walking patterns during rehabilitation training is a urgent problem to be solved.
