The objective of this study was to determine diagnostic and prognostic values of proximal radial motor conduction in acute compressive radial neuropathy.
Thirty-nine consecutive cases of acute compressive radial neuropathy with radial conduction studies-including stimulation at Erb's point-performed within 14 days from clinical onset were reviewed. The radial conduction data of 39 control subjects were used as reference data.
Thirty-one men and eight women (age, 45.2±12.7 years, mean±SD) were enrolled. All 33 patients in whom clinical follow-up data were available experienced complete recovery, with a recovery time of 46.8±34.3 days. Partial conduction block was found frequently (17 patients) on radial conduction studies. The decrease in the compound muscle action potential area between the arm and Erb's point was an independent predictor for recovery time.
Proximal radial motor conduction appears to be a useful method for the early detection and prediction of prognosis of acute compressive radial neuropathy.
本研究的目的是确定急性压迫性桡神经病变时桡神经近端运动传导的诊断和预后价值。
回顾了39例临床发病14天内进行桡神经传导研究（包括在Erb点刺激）的急性压迫性桡神经病变连续病例。将39名对照受试者的桡神经传导数据用作参考数据。
纳入31名男性和8名女性（年龄45.2±12.7岁，均值±标准差）。所有33例有临床随访数据的患者均完全恢复，恢复时间为46.8±34.3天。在桡神经传导研究中经常发现部分传导阻滞（17例患者）。手臂与Erb点之间复合肌肉动作电位面积的减小是恢复时间的独立预测因素。
桡神经近端运动传导似乎是早期检测和预测急性压迫性桡神经病变预后的有用方法。
