| Outline of Final Research Achievements |
It is generally accepted that quadrupedal walking gait in primates differs from that in other mammals such as dogs hand horses, since primates generally employ a diagonal sequence walking gait but other mammals use a lateral sequence walking gait. However, the mechanism responsible for the unique characteristics of the quadrupedal walking gait in primates still remains unclear. The present study conducted a forward dynamic simulation of lateral- and diagonal-sequence quadrupedal gait to evaluate effect of the difference in footfall patterns on gait mechanics. We also analyzed quadrupedal walking gaits of the common marmoset, a primate species known to employ lateral sequence gait, and the Japanese macaque to comparatively investigate the mechanism responsible for the choice of gait sequence.
