Five-freedom degree dermaskeleton type upper limb rehabilitation robot interactive rehabilitation training control policy

The invention provides a five-degree of freedom exoskeleton-type upper limb recovery robot interactive recovery training control strategy. The strategy comprises two training patterns corresponding to the different recovery period of a patient, i.e. a passive interactive recovery training control strategy and an active-auxiliary interactive recovery training control strategy; during passive movement, a surface myoelectric signal of relevant muscles on a healthy upper limb of a patient is picked up and taken as the movement intention of the patient, thereby controlling a robot to drive a diseased side to realize movement passive training; during active movement, the movement intention of an upper limb of a human body is judged through acquiring in real time the arthrosis force moment generated by a diseased limb acting on the robot during movement, and an applied force is converted into the velocity quantity of the tail end of a mechanical arm by means of a proportional controller, thereby driving the robot to follow the intention so as to carry out recovery active-auxiliary training of the diseased limb. The five-degree of freedom exoskeleton-type upper limb recovery robot interactive recovery training control strategy can provide all-around recovery training movement for a clinic hemiplegia patient, thereby increasing the activeness of the patient in recovery training and the confidence of the patient in recovery; meanwhile, the recovery training control strategy also increases the attractiveness of a recovery process and promotes recovery efficacy.

Device for healing and training shoulder joint

The invention discloses a wearable shoulder joint rehabilitation training device. The device has the characteristics of exercise flexibility, wearing comfort and training safety. The device is composed of a movement mechanism and a support adjustment mechanism. The support adjustment mechanism is used to adjust the position of the movement mechanism relative to the shoulder joint of the human body, and fix the entire rehabilitation training device at an appropriate position on the back of the human body. The driver of the motion mechanism is four pneumatic muscles in a vertical motion state, which can respectively control the two groups of movements of the upper arm around the shoulder joint, flexion and extension, abduction and adduction, and the compound movement of these two groups of movements. With the cooperation of the angular displacement and the tension sensor, the active and passive coordinated movement of the movement mechanism and the upper arm can also be realized. The movement mechanism drives the upper arm movement with the help of two sliders for passive movement, which overcomes the problem of upper limb movement difficulties caused by the misalignment between the movement center of the mechanism and the shoulder joint, and ensures the comfort and safety of the training during rehabilitation training .
