Postural control during stance was investigated using the EQUITEST system in 10 patients during recovery after an acute unilateral vestibular lesion and was compared to the time course of recovery of the static and dynamic vestibulo-ocular imbalance. During the acute phase the patients showed a characteristic pattern with normal upright stance as long as at least one accurate sensory input (visual or somatosensory) was provided and severe postural disturbances when they had to rely primarily on vestibular afferences. Both static vestibulo-ocular and vestibulo-spinal balance recovered very fast, showing basically normal results on postural testing within about 2 weeks after the lesion. Thereafter, no pathological pattern was detectable during postural testing even in patients with persistent complete unilateral vestibular lesions. Reflexive postural responses to unexpected rapid displacements of the support surface seemed not to be influenced by vestibular imbalance even in the acute phase of the lesion.
使用EQUITEST系统对10例急性单侧前庭病变恢复期患者的站立姿势控制进行了研究，并将其与静态和动态前庭眼失衡的恢复时间进程进行了比较。在急性期，只要至少提供一种准确的感觉输入（视觉或体感），患者就能保持正常的直立姿势，而当他们主要依靠前庭传入时，则会出现严重的姿势紊乱。静态前庭眼和前庭脊髓平衡恢复得非常快，在病变后约2周内的姿势测试中基本显示正常结果。此后，即使在持续性完全单侧前庭病变的患者中，姿势测试期间也未检测到病理模式。即使在病变急性期，对支撑面意外快速位移的反射性姿势反应似乎也不受前庭失衡的影响。
