Limb assisted rehabilitation system for patients with stroke sequelae

Abstract

The invention discloses a limb assisted rehabilitation system for patients with stroke sequelae. The system is mainly composed of a main frame, a motion generating mechanism and a motion executing device. Through the motion generating mechanism and initial position planning, the reciprocating movement of two pedals of lower limbs in opposite phases and the synchronous movement of an upper limb rotating rocker arm can be achieved only by the continuous motion of one driving motor. The system has a variety of rehabilitation training modes, and cooperates with a lifting device and a multi-functional seat back, and a patient can passively perform lower limb gait rehabilitation training and upper limb rehabilitation training in standing and sitting postures, and can perform infinitely variablecontrol on training amplitudes and frequencies according to physical conditions. The system also adopts a biasing rod between the pedals and the end of a connecting rod to achieve the movement characteristics of a standard centroid sliding bloc mechanism and eliminate the rapid return of the pedal motion.

Description

technical field [0001] The invention relates to the technical field of rehabilitation robots, in particular to a limb-assisted rehabilitation system for patients with stroke sequelae. Background technique [0002] With the characteristics of high morbidity, high mortality and high disability rate, stroke ranks first among adult disabling diseases in my country. Traditional limb rehabilitation systems often only train the lower limbs, and adopt a treadmill-like crawler design. Patients need to complete leg raising by themselves or use other additional devices to assist in leg raising and other actions. This one-way crawler system is effective for stroke sequelae The patient's limb rehabilitation mode is single and the effect is limited. It is difficult to fully recover the joints and muscle groups of the limbs. This not only increases the difficulty of rehabilitation training, but also greatly increases the manufacturing cost of the rehabilitation system. Contents of the in...
