In the diagnosis of functional weakness and sensory disturbance, positive physical signs are as important as absence of signs of disease. Motor signs, particularly Hoover's sign, are more reliable than sensory signs, but none should be used in isolation and must be interpreted in the overall context of the presentation. It should be borne in mind that a patient may have both a functional and an organic disorder.
在功能性肌无力和感觉障碍的诊断中，阳性体征与无疾病体征同样重要。运动体征，尤其是胡佛征，比感觉体征更可靠，但任何体征都不应孤立使用，而必须结合临床表现的整体情况进行解读。应当牢记，患者可能同时患有功能性和器质性疾病。
