Investigating neural mechanisms underlying visual-motor priming in an action execution paradigm

Brain Computer Interfaces (BCIs) represent a promising approach for upper limb rehabilitation after stroke. However, current systems mainly provide feedback on neural activity and rely on the patient’s ability to internally generate appropriate motor representations. In this context, the integration of visual motor priming—based on action observation prior to task execution—may support the recall of motor schemas and enhance cortical responsiveness during training. This study explores the cortical effects of different types of visual motor priming during a hand extension task in a group of healthy subjects and a post-stroke patient. Clinical Relevance— The results may guide the integration of visual motor priming into BCI-based rehabilitation to improve post-stroke motor recovery.
