To determine the value of the extensor digitorum reflex in neurologic examination.
The extensor digitorum, biceps, and brachioradialis reflexes were elicited in 65 patients with hemiplegia and upper-limb paralysis and in a control group of 120 apparently healthy people. Reflexes were elicited by both conventional means and a new method for the extensor digitorum reflex. The sensitivity and specificity of the extensor digitorum reflex were compared with that of the conventional biceps and brachioradialis reflexes to evaluate the value of the extensor digitorum reflex for neurologic examination.
The sensitivity of the extensor digitorum, biceps, and brachioradialis reflexes were 93.65%, 90.48%, and 90.48%, respectively. The specificity of the extensor digitorum, biceps, and brachioradialis reflexes were 95.83%, 94.17%, and 93.33%, respectively. The diagnostic efficacies of the extensor digitorum, biceps, and brachioradialis reflexes were 95.08%, 92.90%, and 91.26%, respectively. There were no significant differences (p > 0.05) in sensitivity, specificity, or accuracy among the extensor digitorum, biceps or brachioradialis reflexes in neurologic examination.
The extensor digitorum reflex is a sensitive and useful deep tendon reflex and is suitable for widespread use in neurological examination.
确定指伸肌反射在神经学检查中的价值。
对65例偏瘫和上肢麻痹患者以及120名明显健康的对照组人员进行指伸肌、肱二头肌和肱桡肌反射检查。通过传统方法和一种新的指伸肌反射方法引出反射。比较指伸肌反射与传统肱二头肌和肱桡肌反射的敏感性和特异性，以评估指伸肌反射在神经学检查中的价值。
指伸肌、肱二头肌和肱桡肌反射的敏感性分别为93.65%、90.48%和90.48%。指伸肌、肱二头肌和肱桡肌反射的特异性分别为95.83%、94.17%和93.33%。指伸肌、肱二头肌和肱桡肌反射的诊断效率分别为95.08%、92.90%和91.26%。在神经学检查中，指伸肌、肱二头肌或肱桡肌反射在敏感性、特异性或准确性方面无显著差异（p>0.05）。
指伸肌反射是一种敏感且有用的深腱反射，适用于在神经学检查中广泛应用。
