Abstract
Abstract: Stretching and releasing the femoral chordotonal organ caused by a movement of the tendon of the organ gives rise to a movement of the tibia. This reaction is called “Kniesehnenreflex” (knee-tendon-reflex). Its step response can be described in the following manner: After a certain reaction-time (at flexion 0.02–0.06 sec, at extension 0.06–0.2 sec) the tibia moves with a maximum speed between 150°/sec and 1000°/sec at extension and between 20°/sec and 450°/sec at flexion. The amplitude of the movement and the maximum speed of tibia movement are correlated. After reaching the extreme position the tibia returnes nearly to its starting-point with half lifes of 3–58 sec after a flexion and 7–232 sec after an extension. — The frequency response shows a strong decrease of the amplitude of the tibia at about 1 Hz. Above 2 Hz the amplitude is only a few degrees. The phase shift between stimulus and reaction increases with increasing frequency. Big individual differences are observed. A step stimulus, which is given in addition to a sinoidal stimulus causes a response at all frequencies. — Slow stretching and releasing the chordotonal organ with constant speeds causes movements of the tibia even at stimulus speeds of 0.002 mm/min. — It is discussed: the significance of the results for the theory of the control mechanism at walk, the stability of the control system in connection with the rocking-movements of the animal and the control of Flexibilitas cerea.
