Median, ulnar, and radial nerve conduction studies (NCS) were performed in 44 subjects. Student's t-test was used to compare nerve conduction velocities (NCV), distal latencies (DL), and distal amplitudes (DAMP) for the two sexes. Only the sensory DAMPs showed statistical significance (p < .001) for gender. Women had greater mean median (52.4 microV vs 31.4 microV), ulnar (52.9 microV vs 27.0 microV), and radial (46.1 microV vs 20.1 microV) sensory DAMPs. Stepwise linear regression analysis of NCVs, DLs, and DAMPs on gender and arm length showed statistical significance only for the median (R2 = .46, p < .001), ulnar (R2 = .59, p < .001), and radial sensory DAMPs (R2 = .29, p < .001) for gender. Arm length did not account for any additional variability. Gender showed an effect on the distal sensory DAMPs obtained by antidromic technique in this study. In contrast to the reported effect of leg length and height on lower limb studies, arm length did not affect upper limb studies.
对44名受试者进行了正中神经、尺神经和桡神经传导研究(NCS)。采用学生t检验比较两性的神经传导速度(NCV)、远端潜伏期(DL)和远端波幅(DAMP)。只有感觉DAMP在性别方面具有统计学意义(p < 0.001)。女性的正中神经(52.4微伏对31.4微伏)、尺神经(52.9微伏对27.0微伏)和桡神经(46.1微伏对20.1微伏)感觉DAMP均值更高。对NCV、DL和DAMP关于性别和臂长的逐步线性回归分析显示,仅正中神经(R2 = 0.46,p < 0.001)、尺神经(R2 = 0.59,p < 0.001)和桡神经感觉DAMP(R2 = 0.29,p < 0.001)在性别方面具有统计学意义。臂长并未解释任何额外的变异性。在本研究中,性别对通过逆向技术获得的远端感觉DAMP有影响。与报道的腿长和身高对下肢研究的影响相反,臂长并未影响上肢研究。
