摘要：Mirror Visual Feedback (MVF) with a mirror box and Virtual Reality based MVF (VR-MVF) are known as one of several therapies within a rehabilitation for improve- ment of motor function after stroke and pain control. Our paper focuses on cognitive functions of temporal consistency between prediction with motor imagery and visual in- formation related to motor movements in using MVF and VR-MVF because of common features of the both MVFs. Healthy participants tried completing an experimental task to synchronize prediction of visual change of motor movements with motor imagery and visual information about motor movements in a virtual environment resembling VR- MVF. In the experimental tasks, visual information was provided in two conditions which are temporal delayed and not delayed. We evaluated that success and failure of twelve trials in experimental tasks, cortical activations measured with functional Mag- netic Resonance Imaging (fMRI) and subjective experience collected by questionnaire during performing the experimental tasks. The participants could complete the consis- tency prediction of visual change and visual information in motor movements on the virtual environment. We found that prediction error is perceived when the prediction of visual change in motor movement is not consistent with visual information about mo- tor movement, and there are interindividual variability in the task completion related to the consistency. This suggests temporal consistency between prediction with motor imagery and visual information related to motor movement may be able to contribute motor learning on VR-MVF.
