The kinematics of wiping movements to the back were examined in spinal adult Rana Catesbeiana. The aim was to identify the elements of the back wipe and their functional role. The data show that there are three essential phases of the wiping movement: a placing phase; a flexion of the hip and knee; and a whisk/extension phase. The first phase is the only one which is dependent upon stimulus location. The spinal frog adjusts the hindlimb to account for stimulus location in the rostro-caudal direction. There is no adjustment for stimulus position along the medial-lateral axis of the body. It is proposed that the second phase serves as a preparatory movement for the extension portion of the wipe. When the wipe is partitioned into these phases, the motion was found to be planar for the first and third phases. At the end of the first phase there was a transition between the two planes.
