Sensorimotor disorder can be easily caused by stroke, and there are many targeted movement rehabilitation therapies. With the development of rehabilitation robot technology, robot-assisted therapy combined with mechanical perturbations has become a more effective motor rehabilitation therapy. In this paper, the definition of mechanical perturbation and its physiological mechanism in stroke rehabilitation are introduced, the research progress on mechanical perturbation in the field of stroke rehabilitation therapy is mainly discussed, the application of mechanical perturbation in motor control, postural response and sensory evaluation of stroke rehabilitation is summarized, and the future development direction of mechanical perturbation rehabilitation therapy is also prospected.
