Background technique

my country has begun to enter an aging society. According to relevant statistics, the number of deaths due to stroke and cardiovascular and cerebrovascular diseases reaches 2.6 million people every year, and more than 15 million people are unable to take care of themselves due to surgery and other reasons. In patients with hemiplegia, early rehabilitation training can effectively improve the limb function of the patient and promote the walking function of the patient, and the effect is remarkable. The treatment of patients with hemiplegia and lower extremity movement disorders has been developing. Traditional rehabilitation therapy usually includes body position change, balance training, joint exercise, walking and muscle strengthening methods, assisted by medical staff. However, the limitations and disadvantages of the traditional method are obvious. There are many rehabilitation training items, a large number of experienced medical staff are needed, and the degree of mechanization is low.

In recent years, various rehabilitation training devices (robots) have appeared. Under the guidance of doctors, patients can use these rehabilitation training equipment to complete limb rehabilitation training at home, which not only saves rehabilitation costs, but also ensures a certain degree of rehabilitation training intensity. However, many of the existing lower limb rehabilitation training devices have the disadvantages of many degrees of freedom, large volume, high price, etc., and lack of rehabilitation training for the lower limb hip joints of patients who cannot take care of themselves such as hemiplegia.
