Abstract

1. (1) We have investigated the kinematics of running on a treadmill of dogs with damage to the cerebellum. The deviations from normal were most strongly marked in the fore limb on the side of damage. 2. (2) The mean values of certain kinematic quantities vary: amplitude and angular speeds of movement in the joint and duration of the transfer phase of the limb. 3. (3) The fluctuations greatly increase and there are significant correlations between the fluctuations of many elements of movements. 4. (4) The trajectory of transfer of the limb closely depends on a number of factors (additional load on the fore limbs) having scarcely any effect on kinematics in intact animals. 5. (5) It is assumed that the disturbances in coordination observed on damage to the cerebellum are based on release of a number of links in the system of control movements blocked on locomotion of intact animals.
