[Experimental research on sensitized posturography: importance of the neck reflexes].

: In order to assess the influence of the cervical structures on the vestibulo-spinal reflex, and so on the posture, we have studied twenty subjects undergoing stimulation of the neck's proprioceptor structures. Each subject, by means of computerized stabilometric platform, has been submitted to the sensitized test with head retroflexed. In all cases significant variations of the posturographic parameters regarding in a particular way the total tracing length, the ellipse surface and the mean speed have been recorded. The results show that there are in man too stimulations of cervical origin which serve the purpose of maintaining posture; we can't exclude the possibility of the interference of an otolithic stimulation.
