Objectives: 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. Design: Cross- sectional survey. Setting: University hospital. Participants : Forty-seven men with paraplegia and 36 able- bodied controls underwent nerve conduction studies on both upper limbs. None reported any hand numbness in the past month, diabetic mellitus, or neuromusculoskeletal injuries to the upper limbs. Interventions: Not applicable. Main Outcome Measure: Nerve conduction studies on the bilateral median and ulnar nerves . Results: 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 the SCI group and higher BMI was associated with prolonged motor and sensory latency of the median nerve. Conclusions: The asymptomatic subjects with paraplegia had a significantly higher frequency of median mononeuropathy than the able-bodied controls. An association between BMI and distal latency of the median nerve was also observed. ; 附設醫院復健部 ; 醫學院附設醫院 ; 期刊論文
