| Outline of Final Research Achievements |
Repetition of toe-up rotation after repetitive backward translations of floor induce adaptive inhibition of stretch reflex response in the trips surae, which would be related to supraspinal nervous system. This study investigated the changes in the activation of the lower limb, trunk, and shoulder girdle muscles and the contingent negative variation of the brain potential with the toe-up rotations after the backward translations. When the intensity of the rotation was strong, the activation of the triceps surae just after the rotation was adaptively decreased with the repetition of the rotation, and the activation of the thigh and trunk muscles and upper trapezius was also decreased. The brain activation for the anticipatory attention and motor preparation temporally decreased just after the switching of the floor perturbation to the toe-up rotation.
