Problem statement: Motor Imagery (MI), which corresponds to an active process during which the representation of a specific action is internally reproduced into working memory without any motor output. It represents the result of conscious access to the content of a movement intention, which is usually performed unconsciously during movement preparation. Approach: This review study aims to provide information on the current research and main findings related to the potential therapeutic effects of motor imagery on stroke neurorehabilitation. Results: Several studies demonstrate that conscious motor imagery and unconscious motor preparation share common mechanisms and are functionally equivalent, improving recovery of motor skills in stroke patients. Conclusion: In conclusion, motor imagery, proved very useful and effective, with significant results in improvement of motor deficits in post stroke patients. Thus, it is recommended that further studies must be conducted to determine specific parameters such as number and weekly frequency, duration (minutes per session), type (visual or kinesthetic) and the appropriate moment to apply mental practice (phases recovery of pathology), in order to create specific protocols for each treatment phase.
