| Outline of Final Research Achievements |
The trunk fixation method and data acquisition parameters for functional MRI during stepping were investigated. The measurements of head velocities during stepping by using motion capture system and fMRI acquisitions were performed to twelve healthy volunteers. The head velocity during stepping decreased statistically significant difference by using the trunk fixation method. Moreover, the motor areas of the legs were represented on fMRI activation map in every case and the deactivation areas, which caused by motion artifact, were smaller in some cases. However, the trunk fixation method could not reduce deactivation areas in other cases. We could theoretically moderate the image acquisition parameters to match the data acquisition time with the smaller head velocity time. Further investigations need in future work.
