Effect of the cervical reflex on the posture of normal subjects. Balance measurement study

The little we know about the existence and the meaning of the cervical component on the vestibulo-spinal reflex, led us to carry out a study on normal subjects examined by computerized stabilometry with the head turned 75 degrees left and right, in order to check the postural alterations during the stimulation of the neck proprioceptors. The results show a significant increase of the values of the LTT, SE and Vm with the head turned to the left; the increases were not significant with the head turned to the right. The difference is difficult to explain. The results show that in man too the posture is affected by reflex of cervical origin.
