The durations of clonus burst were found longer than the durations of Soleus medium-latency reflex (MLR). There is a similarity in their nature, although the speed and cause of the stretch of triceps surae differ in the MLR and the clonus, and there is a sufficient period of time for group II afferents and for other spinal mechanisms to be involved in the clonus, together with Ia afferents.
