The reliability of a scale of 0 to 4 (where 0 is normal) in rating the severity of blepharospasm (BS) and oromandibular dystonia (OMD) was evaluated by the concordance among six neurologists from different neurological institutions. As expressed by k index, interobserver agreement was moderate either for BS or for OMD according to the Landis classification. Neurologists showed different rating attitude toward BS and OMD. In fact, the category analysis showed that raters were inclined to overestimate BS and to underestimate OMD. The familiarity with dystonia influenced reliability more than the length of professional experience in neurology. In fact, when examiners were subdivided into subgroups (each of three raters) according to the former criteria, the level of interobserver agreement increased significantly. Almost perfect agreement was obtained in intrarater comparisons. These results may be of value with regard to the conduct of multicenter epidemiologic and clinical studies on focal dystonias.
通过来自不同神经机构的六位神经科医生之间的一致性，评估了0至4级量表（0表示正常）对眼睑痉挛（BS）和口下颌肌张力障碍（OMD）严重程度评级的可靠性。根据Landis分类，用k指数表示，观察者间一致性对于BS或OMD来说均为中等。神经科医生对BS和OMD表现出不同的评级态度。事实上，类别分析表明，评级者倾向于高估BS并低估OMD。对肌张力障碍的熟悉程度比神经科专业经验的长短对可靠性的影响更大。实际上，根据前一标准将检查者细分为亚组（每组三名评级者）时，观察者间一致性水平显著提高。在同一评级者的比较中获得了几乎完美的一致性。这些结果对于开展关于局灶性肌张力障碍的多中心流行病学和临床研究可能具有价值。
