摘要：

The rehabilitation scheme based on passive training of standard gait cannot satisfy the rehabilitative training requirements of lower limb paralysis patients with residual muscle strength. A strategy of lower limb exoskeleton rehabilitation robot with human-robot interaction force adaptive control is hence proposed, and a rehabilitative training method is designed. This method takes the walking gait of healthy human body as a reference for the position control of the exoskeleton rehabilitation robot of lower limbs, and takes the wearer's own leg force as the force control constraint to intelligently control and adjust the gait curve according to the wearer's own leg strength, so as to better meet the wearer's rehabilitation training needs. Simulation results show that the adaptive force control mode can effectively adjust the human-robot interaction force in the rehabilitation process, and can adapt to a variety of different rehabilitation training requirements to greatly improve the rehabilitation treatment process of motor function recovery of injured limbs. © 2019, Editorial Office of Journal of Xi'an Jiaotong University.
