检体诊断教学中Hoffmann征检查结果真假阳性分析

Effect of Wrist Joint Angle on the Examination of Hoffmann Reflex in Diagnostics Teaching

目的探讨诊断检体教学中腕关节不同屈伸角度对Hoffmann征检查结果的真假阳性干扰影响。方法对34例明确诊断为脊髓型颈椎病的患者及40名正常人的双手在腕关节掌屈15°、中立0°、背伸30°、背伸60°位分别行Hoffmann征检查,并对所得结果进行统计学处理。结果在脊髓型颈椎病患者中,腕关节中立0°、背伸30°、背伸60°位Hoffmann征检查结果无显著差异,而与掌屈15°位Hoffmann征检查结果存在显著差异(P<0.05)。结论腕关节不同屈伸角度对Hoffmann征检查结果有明显影响,而以腕关节背伸30°位为可靠。

Objective To explore the effect of wrist angle on the examination of Hoffmann reflex. Methods 34 eervical myelopathy patients and 40 normal persons were examined for Hoffmann reflex respectively at 15°of palmar flexion, neutral position and 30°, 60°of dorsiflexion. The results were statistically analyzed. Results In the cervical myelopathy patients, no significant differences were found among the results of Hoffmann reflex at neutral position, 30° and 60° of dorsiflexion, but there was significant difference between the results of Hoffmann reflex at 15° of palmar flexion and that at neutral position,30°,60°of dorsiflexion. Conclusion Different wrist joint angles has significant effect on the result of Hoffmann reflex. The examination result at 30°of dorsiflexion is the most reliable.
