The influence of vestibular dysfunction upon the vestibulospinal reflex (VSR) in two common peripheral syndromes was investigated by two types of posturographic examination: "static" posturography, recording and analyzing the postural sway in stance, and "kinetic" posturography, recording the stepping in place test. The influence of the dysfunction was examined outside the attacks, ie, between attacks and not during or immediately after an attack, in patients with Meniere's disease and in others with a sudden vestibular loss syndrome, "neuronitis." However, in both syndromes the influence of the dysfunction was obvious only in some patients; this indicates that central adaptation intervened in the other patients. In this way, central compensation related to the VSR was assessed and compared with compensation for the vestibulo-ocular reflex assessed by the rotation tests. Discordance was shown in a number of cases, ie, a number of cases showed compensation for one reflex, but not for the other. Comparison of the results of both posturographic methods also showed discordance. Normal performance in the walking test could not always be correlated with normal performance in the standing test and vice versa.
通过两种姿势描记检查,研究了两种常见外周综合征中前庭功能障碍对前庭脊髓反射(VSR)的影响:“静态”姿势描记法,记录并分析站立时的姿势摆动;“动态”姿势描记法,记录原地踏步测试。在发作间期,即发作之间而非发作期间或发作后立即检查功能障碍的影响,研究对象为梅尼埃病患者以及其他患有突发性前庭丧失综合征(“神经炎”)的患者。然而,在这两种综合征中,功能障碍的影响仅在部分患者中明显;这表明中枢适应性在其他患者中发挥了作用。通过这种方式,评估了与VSR相关的中枢代偿,并与通过旋转测试评估的前庭眼反射的代偿情况进行了比较。在许多病例中都出现了不一致的情况,即一些病例显示一种反射有代偿,但另一种反射没有。两种姿势描记方法的结果比较也显示出不一致。步行测试中的正常表现并不总是与站立测试中的正常表现相关,反之亦然。
