[The role of vestibular and proprioceptive afferent pathways in the reaction to pushing (author's transl)].

The reaction to pushing was studied in 6 normal subjects and 3 patients with bilateral peripheral vestibular lesions. The reaction to pushing was tested on the anterior tibial and soleus, by modifying the proprioceptive afferent impulses. The respective parts of the vestibular, proprioceptive, visual components, and of a sudden, start are analyzed; the afferent impulses obtain information from the initial posture and modulate the relative importance of these different factors at a supra-segmentary level.
