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