| Outline of Final Research Achievements |
It is well known that vibrating the tendon of human limbs evokes the illusion of motion. There are no previous reports on the influence of joint angle in motion illusion evoked by tendon vibration. Therefore, we compared the motion illusion under two different joint angle by subjective assessment in three aspects: the strength of illusion, range of extension, and velocity of extension. The results showed that all three aspects were affected by the joint angle. In addition, we compared the motion illusion under two different joint angle in two more aspects quantitatively: the latency and duration. The results indicate that the latency and duration of the motion illusion were not affected by the joint angle.
