Outline of Final Research Achievements

To identify the role of human primary motor cortex in walking, this study examined intramuscular tibialis anterior (TA) coherence during 1) steady-state walking, 2) walking with dual task, 3) walking with weight on the toe, 4) walking while stepping over an obstacle. There were significant differences in intramuscular coherence among 4 conditions. This finding indicates that cortical participation during walking is modified depending on the situations of walking.
