Motor imagery in upper limb post-stroke rehabilitation: a narrative review

Abstract

Introduction: Considering that the brain is a highly complex and organized organ, the severity and impairment of deficits caused by a Stroke largely depend on their extent and location. These deficits are the result of the loss of neural circuits linked to sensory, motor, and cognitive functions. Various clinical studies indicate that mental training through motor imagery (MI) appears to be effective when associated with neurorehabilitation, in the recovery of upper limb function. Objective: To explore the theoretical aspects of using MI in upper limb rehabilitation post-stroke, through a narrative review. Methods: Research was conducted in bibliographic sources through the databases PubMed, EBSCOhost, CINAHL, Scopus, Web of Science, and PEDro, with the last search carried out on 30th May 2023. Results: RCT articles and systematic reviews that addressed the effects of motor imagery on upper limb function were selected for review. Conclusion: The articles analysed in this review point to a positive relationship between the effects of MI and the recovery of upper limb post-stroke, particularly when this technique is combined with Occupational Therapy and Physiotherapy, reinforcing the importance of considering the introduction of mental training with Motor Imagery in rehabilitation programs.
