Abstract
In patient suffering from unilateral disequilibrium with the features of the sensorimotor induction syndrome, closure of the eyes as done on performance of the Romberg test is modified in that the eyes are closed alternately. The result is that the postural condition of these patients presents a different attitude. On vision with the eye corresponding to the side of disequilibrium, the same basic tendency to fall and displacement of the homolateral extremities result as when seeing with both eyes. This result is explained on the basis of the characteristic feature of the sensorimotor induction syndrome, in which the coordinates of space deviate when seen with the homolateral eye. However, on vision with the contralateral eye the tendency to fall is eliminated regularly and displacement of the homolateral extremities is reduced or entirely abolished. This effect is attributed to the extensive mutual influence of motor and sensory functions, another characteristic feature of this syndrome. The phenomenon taking place here is assumed to be due to the optic influence of light on postural attitude and therefore belongs to the sphere of sensory influence of statokinetic conditions.
