| Outline of Final Research Achievements |
Activation of postural muscles that precede a prime mover of arm movement became evident for the triceps surae when initial standing position was located more forward than quiet standing position in 20-42 year old subjects. Corresponding to the muscle activity a brain potential that reflects preparation and attention for postural control showed larger peak amplitude from the earlier point of preparation period. In contrast, 58-75 year old subjects exhibited no initial position-related change in the triceps surae and the brain potential. It was suggested that both modality of postural control and brain activity related to preparation and attention are different between younger and senior adults.
