Rudneva, É. Slivko] In testing of healthy subjects, we studied the influence of conditioning stimulation of then.peroneus communis on the H-reflex EMG discharge recorded from them. soleus. Two waves of inhibition separated by a period of relative facilitation of the reflex were observed. The first wave,D 1, was not longer than 50 msec. The intensity of later inhibition (D 2 wave) within a 500 to 4000 msec time segment linearly depended on the logarithm of the interval between the conditioning and test stimuli. Extrapolation showed that the duration of this wave could be evaluated as equal to 6.3 msec, on average. We also studied the temporal course of H-reflex inhibition after conditioning vibrational stimulation of the receptors of them. tibialis ant. andm. biceps femori. Within a 500 to 4000 msec test interval, it could also be fitted with a logarithmic dependence similar to that observed after electrical stimulation of then. peroneus comm. The duration of inhibition after vibrational stimulation of them. tibialis ant. andm. biceps femori was 6.2 and 8.9 sec, respectively. Inhibition evoked by both conditioning influences was not removed after a voluntary plantar flexion of the foot. Our observations support the statement that in humans stimulation of the afferent fibers from the antagonist muscles, as well of the muscle receptors, evokes in two-neuron reflex arcs presynaptic inhibition, whose duration reaches several seconds; this phenomenon can play a significant role in the control of muscle tone in the course of muscle performance.
