Abstract		Stretch reflexes of posterior tibial (PT) and triceps surae (TS) muscles were studied electrophysiologically in 27 children with unoperated unilateral congenital equinovarus deformity, in an attempt to evaluate changes in tone of the leg muscles as a possible pathogenetic factor. Significantly reduced latency of the PT responses on the affected side was recorded in a majority of patients. In most patients the amplitudes of the PT responses were asymmetrical; however, lateralization was inconsistent. The TS responses were asymmetrical in a smaller proportion of the patients, though still significantly different from the controls. The findings suggest an asymmetrical increase in excitability level of the PT motoneuron pool on the affected side.
