To investigate the role of cervical proprioceptive inputs in the process of vestibular compensation, we performed static posturography in patients with acute and compensated unilateral vestibular dysfunction, by applying vibratory stimulation to the dorsal neck muscles. Neck vibration induced disequilibrium in both groups of patients, but was more pronounced in the compensated patients. These results indicate that manipulation of the neck afferents causes discompensation in subjects whose vestibular dysfunction has already been compensated by multisensory inputs including neck afferents.
为了研究颈部本体感觉输入在前庭代偿过程中的作用，我们对急性和代偿性单侧前庭功能障碍患者进行了静态姿势描记法检查，通过对颈背部肌肉施加振动刺激。颈部振动在两组患者中均诱发了失衡，但在代偿性患者中更为明显。这些结果表明，在前庭功能障碍已通过包括颈部传入在内的多感觉输入得到代偿的受试者中，对颈部传入神经的操作会导致失代偿。
