目的 探讨人体倾角姿态图对眩晕患者的临床诊断价值。方法 对反复发作眩晕和 /(或)有失平衡感症状的 307例患者行眼震电图(ENG)和倾角姿态图检查,比较两种检查结果。结果 (1)有失平衡感症状的患者较无失平衡感症状的患者更多地显示了倾角姿态图的异常。(2)冷热水试验诊断外周性前庭病变的敏感性明显高于中枢性前庭病变(分别为 74. 6%和 34. 7% );而倾角姿态图诊断外周性和中枢性前庭病变的敏感性差异无统计学意义(分别为 56. 9%和 52. 0% );在外周性和中枢性前庭病变中,两种检查结果的不一致率均较高 (为 43. 1% 和 60. 0% )。结论 人体倾角姿态图能直接鉴别患者平衡功能的缺损,与ENG结合不仅可全面有效地评估前庭平衡系统的功能状态,而且能提高对前庭病变的鉴别能力。
Objective To investigate the clinical diagnostic value of human inclination gesture in vertigo patients. Methods 307 patients with recurrent vertigo and / or imbalance symptoms were examined by electrogram of electrogram (ENG) and dip angle, and the results of two examinations were compared. Results (1) Patients with symptoms of imbalance showed more abnormalities of their attitude of inclination than those with no symptoms of balance. (2) The sensitivity of hot and cold water test to diagnose peripheral vestibular lesions was significantly higher than that of central vestibular lesions (74.6% and 34.7%, respectively); while the tilt angle posture was sensitive to peripheral and central vestibular diseases There was no significant difference in sex (56.9% vs 52. 0%, respectively); in both peripheral and central vestibular lesions, the inconsistencies between the two examinations were high (43.1% and 60.0% %). Conclusions Body tilt attitude can directly identify the impairment of patients’ balance function. Combined with ENG, it not only can evaluate the functional state of vestibular balance system comprehensively and effectively, but also can improve the discrimination ability of vestibular disease.
