The influence of patient-related factors on inter-observer variability in the evaluation of neurological signs was investigated. Two hundred and two consecutive unselected inpatients were examined by two senior neurologists who were unaware of the neurological case history. Eight signs were evaluated: anisocoria, jerky eye movements, facial palsy, difference in elbow extension force, abnormal finger-nose test, Barré sign, difference in knee jerk, and extensor plantar reflex. Agreement rates were calculated in order to compare the inter-observer variability with reference to the patients' sex, age, mode of admission, and diagnosis at discharge. Observed agreement rates for the eight examined signs only sporadically showed statistically significant differences between the chosen patient-related factors. In general, inter-observer variation does not appear to be influenced by the sex, age, mode of admission or diagnosis at discharge of the patients.
研究了患者相关因素对神经体征评估中观察者间变异性的影响。两位资深神经科医生对202例连续入选的未选定住院患者进行了检查，他们并不知晓患者的神经病史。评估了八项体征：瞳孔不等大、眼球急动、面瘫、肘伸展力差异、指鼻试验异常、巴彬斯基征、膝跳反射差异及跖伸反射。计算一致性率，以便参照患者的性别、年龄、入院方式和出院诊断比较观察者间变异性。所检查的八项体征的观察一致性率仅偶尔在所选患者相关因素之间显示出统计学上的显著差异。总体而言，观察者间变异似乎不受患者的性别、年龄、入院方式或出院诊断的影响。
