To explore characteristics and causes of equilibrium function deficits after traumatic brain injury(TBI).
Ninety-five patients after TBI in traffic accidents were tested using computerized dynamic posturography (CDP). The CDP findings of patients were compared with normal value. The patients were grouped based on TBI and audition disorders degrees. The results were compared within the patients groups.
The equilibrium scores of the TBI group were significantly lower than the normal value. The utilization rate decreased for vision and vestibular sensation information in the TBI group, especially for vestibular sensation. The primary TBI degree and audition decrease had no significant affect on posture stability.
The poor posture stability was observed in TBI patients without limbs disturbance. The response and adaptation abilities decrease in these patients. This could be explained by the damage to peripheral vestibular and central balance structures.
探讨创伤性脑损伤（TBI）后平衡功能缺陷的特征及原因。
采用计算机动态姿势描记法（CDP）对95例交通事故所致TBI患者进行测试。将患者的CDP检查结果与正常值进行比较。根据TBI和听觉障碍程度对患者进行分组。在各患者组内比较结果。
TBI组的平衡分数显著低于正常值。TBI组视觉和前庭感觉信息的利用率降低，尤其是前庭感觉。原发性TBI程度和听力下降对姿势稳定性无显著影响。
在无肢体障碍的TBI患者中观察到姿势稳定性较差。这些患者的反应和适应能力下降。这可以用外周前庭和中枢平衡结构受损来解释。
