摘要
Locomotor analysis is a useful tool for assessing normal and disturbed brain function. Previous studies have indicated that, during locomotion at walking velocities, the rat adjusts its velocity by changes to stride time and length. The present work has shown that, in the Sheffield strain rat, changes in stride time are achieved by a differential deployment of its two components, stance time and swing times. During slow walking, swing time changes provide minimal contribution to stride time reductions. At above average stride frequencies, however, swing time changes become significant, providing for more than half the reduction over parts of the range.
