颅脑损伤后动态姿势平衡评估

Assessment of Dynamic Posture Equilibrium Function after Traumatic Brain Injury

目的探讨颅脑损伤后平衡功能障碍的特点和原因。方法对95例交通事故致颅脑损伤的患者进行动态姿势图检查,将其测试结果与正常值比较;并按照原发颅脑损伤程度和是否伴有听力障碍对患者进行分组,将测试结果进行组间比较。结果颅脑损伤患者平衡总分较正常值低,对视觉和前庭觉等信息的利用能力下降,以前庭觉下降明显;原发颅脑损伤的严重程度以及是否伴听力下降对姿势稳定性无明显影响。结论不伴有肢体功能障碍的颅脑损伤患者的姿势稳定性差,对环境的反应与适应能力下降,可能与外周前庭器官及平衡中枢的损伤有关。

Objective To explore characteristics and causes of equilibrium function deficits after traumatic brain injury（TBI）.Methods 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.Results 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.Conclusion 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.
