To compare electrophysiologic abnormalities of the median nerve in asymptomatic paraplegic subjects and able-bodied controls and to examine the influence of personal factors on these parameters.
Cross-sectional survey.
University hospital.
Forty-seven men with paraplegia and 36 able-bodied controls underwent nerve conduction studies on both upper limbs. All were free of hand numbness in the past month, diabetic mellitus, or neuromusculoskeletal injuries to the upper limbs.
Not applicable.
Nerve conduction studies of the bilateral median and ulnar nerves.
Although the 2 groups were of comparable age and had a similar body mass index (BMI), the subjects with paraplegia had a significantly higher proportion of asymptomatic median mononeuropathy than the controls (25.5% vs 5.6%, P=.02). The spinal cord injury (SCI) group had a prolonged median distal latency and a slowed digit-wrist sensory nerve conduction velocity. Multivariate general linear model analysis showed that prolonged motor and sensory latencies of the median nerve were associated with the SCI group and with greater BMI.
The asymptomatic subjects with paraplegia had a significantly higher frequency of median mononeuropathy than the able-bodied controls. There was also an association between BMI and distal latency of the median nerve.
比较无症状截瘫患者与健全对照者正中神经的电生理异常情况，并研究个人因素对这些参数的影响。
横断面调查。
大学医院。
47名截瘫男性和36名健全对照者接受了双上肢神经传导研究。所有人在过去一个月内均无手部麻木、糖尿病或上肢神经肌肉骨骼损伤。
不适用。
双侧正中神经和尺神经的神经传导研究。
尽管两组年龄相当且体重指数（BMI）相似，但截瘫患者无症状正中单神经病的比例显著高于对照组（25.5%对5.6%，P = 0.02）。脊髓损伤（SCI）组正中神经远端潜伏期延长，手指-腕部感觉神经传导速度减慢。多变量一般线性模型分析显示，正中神经运动和感觉潜伏期延长与SCI组及较高的BMI有关。
无症状截瘫患者正中单神经病的发生率显著高于健全对照者。BMI与正中神经远端潜伏期之间也存在关联。
