[The effect of multiple systematic knee reflex elicitation on its development in young children].
The development of the knee jerk was studied electromyographically in children of two groups: (a) a control group, where children of different age (from one to twelve months) were examined each only once, and (b) an experimental group, in which the knee jerk was elicited in each child repeatedly (every other day) for several months, beginning with the age of one to two of from five to six months. There was no difference between the two groups in the latencies of the phasic component of the reflex. Significant differences were found in the development of the tonic component: its disappearance, occurring with the growth of the child, took place in the experimental group much earlier than in the control one. Thus, intensive afferent stimulation, linked with multiple systematic evoking of the knee jerk, leads to substantial acceleration of the reflex development.
