| Outline of Final Research Achievements |
We applied vibration (0.5-mm amplitude, 60 Hz) to the forefoot soles and evaluated postural responses in healthy adults. Two vibrators (12-mm diameter) were bilaterally attached to the metatarsal head areas at (1) the point of maximum pressure during quiet standing, (2) the anterior area, and (3) the posterior area, which were determined based on the foot pressure distribution and the bearing area of each subject. The vibration to the point of maximum pressure induced backward-lean response (compensatory response) at a higher rate than the vibrations to the other sites. This would suggest that the maximum pressure area under the metatarsal head plays important role in positional perception in quiet standing.
