Objective:

To investigate the neural mechanisms underlying digital mirror visual feedback (MVF) combined with different movement types in stroke patients and healthy controls using EEG, focusing on the differences in neural responses between the two groups.

Key Findings:

• Digital MVF activates motor regions contralateral to MVF in both healthy individuals and stroke patients.
• Bilateral MVF enhances visual attention and perception of limb ownership compared to traditional mirror therapy.
• Mu power attenuation was observed in the central electrodes during both motor execution and observation of MVF, indicating neural engagement.

Interpretation:

The findings suggest that digital MVF, particularly bilateral MVF, may enhance motor function rehabilitation by more effectively engaging motor areas in the brain compared to traditional methods, potentially leading to improved recovery outcomes.

Limitations:

• The small sample size in the stroke group may limit the generalizability of the findings to a broader population.
• Exclusion of participants with severe neglect or aphasia may affect the applicability of results to all stroke patients.

Conclusion:

Digital-based mirror therapy, especially with bilateral MVF, shows promise as an effective rehabilitation strategy for improving motor function in stroke patients.
