Since many patients in the elderly population suffer from neurological or cerebrovascular diseases, the incidence of these diseases in society increases each year, and in the case of stroke, about 70% to 80% of patients develop lower limb dyskinesias.
In recent years, along with rapid development of intelligent rehabilitation technology, the lower limb rehabilitation robot technology enables patients with lower limb dyskinesia to perform scientific and effective rehabilitation training through repeated training of weight reduction and standardized normal physiological gait, and further recovers walking ability, but the training mode is found in clinical practice, and has poor curative effect on recovery of limb functions of patients with muscle strength or parkinsonism below three levels. The exoskeleton system is close to anatomy according to the bionics principle, can realize the organic combination of robot technology and rehabilitation therapy, assists a patient to perform specific joint training and improves body functions, but only 55% of patients receiving rehabilitation therapy recover walking ability.
Patients suffering from nervous system diseases or cerebrovascular diseases often fall to hip fracture due to gait abnormality, so that the recovery of lower limb movement function is difficult and heavy, hip fracture is also the most common lower limb fracture of the elderly, in order to promote walking ability of the patients, surgery is a main method for treating the senile hip fracture, but 40% -60% of the movement functions of the patients are recovered to the pre-fracture level after the surgery, and no relevant report exists in clinic aiming at the lower limb rehabilitation training of the patients after the internal fixation of the hip fracture.
In order to better promote the recovery of muscle strength before standing training of patients with lower limb dysfunction, realize the feasibility of lower limb walking training and further promote the recovery of lower limb walking function, the literature reports that in order to solve the problems, the training mode of a lower limb rehabilitation robot with two degrees of freedom and three compound degrees of freedom, which is designed by an expert, is a horizontal type lower core muscle group training, the training scheme can promote the lower limb rehabilitation training in safe early stage, but still has defects, the training of the lower limb rehabilitation robot with two degrees of freedom is a passive hip knee training mode, the activity degree and the training condition of ankle joints are not considered, and the foot training occupies very important position in the rehabilitation training for recovering the lower limb function. The lower limb rehabilitation robot with three degrees of freedom is designed to meet the rehabilitation motions of thighs, calves, ankle joints and the like, but the driving mode is only hydraulically driven, the robot does not have resistance training, and the rehabilitation difficulty for the muscle strength of the lower limb is high.

1) Training can only be performed under the power system. In clinical application, the passive training mode can only be applied for a short time, and the active training mode is the best method for promoting the patient to better recover the limb functions and physical and mental health.
2) Only in a single limb training mode, multiple limbs cannot be linked.
3) When the hip joint adduction and abduction training is carried out, the movable radian within 0-5 degrees can be only carried out on the transverse track, the radian is too small, and the training effect is limited.
4) The foot support has small activity degree and insufficient freedom degree, and the ankle toe can not plantar flex at the same time of the inward and outward rotation training, and only can passively perform inward and outward rotation under the dorsi extension, so that the muscles can not move in a free and relaxed state, and the muscle ligaments are easily damaged, and the ankle joint can feel muscle tension.
5) The angle of the foot is fixed, the lower limb cannot be relaxed by foot relaxation by means of equipment manipulation, and antispasmodic operation cannot be performed by means of equipment.
