Symptoms and signs of postural instability are often present in patients with Parkinson disease (PD). Because vestibular dysfunction might contribute to the postural instability, we carried out bithermal caloric tests and electronystagmography in 36 patients with PD and 316 controls. Significantly more PD patients had reduced and absent vestibular responses than controls. Decreased or absent vestibular responses in patients with PD were associated with postural instability and increasing severity of other symptoms. Vestibular dysfunction may contribute to the postural instability of PD.
帕金森病（PD）患者常出现姿势不稳的症状和体征。由于前庭功能障碍可能导致姿势不稳，我们对36例PD患者和316名对照者进行了冷热试验和眼震电图检查。与对照组相比，PD患者出现前庭反应减弱和缺失的情况明显更多。PD患者前庭反应减弱或缺失与姿势不稳及其他症状的严重程度增加有关。前庭功能障碍可能导致PD患者的姿势不稳。
