Head stabilization is necessary during human locomotion in order to contrubute to perception of a stable visual field. Head stabilization is du to the cooperation between vestibular system and proprioception. According to cranio-corpographic experience Authors used a device based on two accelormeters place, respectevely, on th head and the trunk of the subject. Head stabilization during locomotion have been evaluated in normals and in pathologica subjects including patients suffering with multiple sclerosis and ataxiaa and cervical pain. In normals head is stabilized with respect to the the trunk despite to sensorial condition of locomotion (eg eyes open or closed, firmed or soft surface). In both ataxic and multiple sclerosis patients head stabilization is decreased but pattern of head instability seems to be specific in multiple sclerosis in which head is more unstable in sagittal than in frontal plane.
