| Outline of Final Research Achievements |
In recent years, rehabilitation techniques using robotic technology-based motion-assist devices have been expected. It is, however, difficult to verify their effectiveness on humans, due to differences in disability level and the level of motivation for training. We developed a rat experimental model able to evaluate the effectiveness of motion-assist devices. The number of days for the rat to learn the correct forepaw (an error rate of less than 15 %) was investigated by varying the timing of intervention and the target forepaw for intervention (on the correct response side or the incorrect response side). The results showed that such intervention influenced learning effectiveness. The learning time frame was less when intervention produced an incorrect motion than when intervention produced a correct motion. We conclude that learning effectiveness can be improved more rapidly when an external force was applied to cause neuronal activities similar to voluntary motion.
