Body lateropulsion may occur without signs of vestibular dysfunction and vestibular nucleus involvement. The authors examined 10 such patients with three-dimensional brainstem mapping. Body lateropulsion without limb ataxia reflected an impairment of vestibulospinal postural control caused by a lesion of the descending lateral vestibulospinal tract, whereas body lateropulsion with limb ataxia was probably the consequence of impaired or absent proprioceptive information caused by a lesion of the ascending dorsal spino-cerebellar tract.
身体侧倾可能在没有前庭功能障碍和前庭核受累迹象的情况下发生。作者对10例此类患者进行了三维脑干映射检查。无肢体共济失调的身体侧倾反映了由外侧前庭脊髓束下行病变引起的前庭脊髓姿势控制受损，而伴有肢体共济失调的身体侧倾可能是由脊髓背侧小脑束上行病变导致的本体感觉信息受损或缺失的结果。
