The theoretical system of motor re-learning is one of the important technical systems in the field of neurological rehabilitation. It is helpful to improve the curative effect of rehabilitation by deeply understanding this theory system and applying it flexibly to patients with neural system impairment. In this paper, the principles of neurorehabilitation based on motor re-learning (including active training, repetitive reinforcement; task-specific practice, goal-orientated training; rich environment, increasing difficulty; emphasis on feedback and early intervention) are interpreted with available evidence of mechanism and clinical application studies, in order to provide some ideas and directions for the future clinical research of neurological rehabilitation.
