Tibial nerves of 10 normal domestic ferrets (Mustela putorius furo) were evaluated by means of electrodiagnostic tests: motor nerve conduction studies (MNCSs), supramaximal repetitive nerve stimulation (SRNS), F waves, and cord dorsum potentials (CDPs). Values of conduction velocity, proximal and distal compound muscular action potentials, and amplitudes of MNCS were, respectively, 63.25 +/- 7.56 m/sec, 10.79 +/- 2.75 mV, and 13.02 +/- 3.41 mV. Mean decrements in amplitude and area of compound muscular action potentials of wave 9 with low frequency SRNS were 0.3 +/- 3.83% and 0.1 +/- 3.51%. The minimum latency of the F waves and the F ratio were, respectively, 8.49 +/- 0.65 ms and 1.92 +/- 0.17. Onset latency of CDP was 1.99 +/- 0.03 ms. These tests may help in diagnosing neuromuscular disorders and in better characterizing the hindlimb paresis reported in many ferrets with systemic illnesses.
通过电诊断测试对10只正常家养雪貂(Mustela putorius furo)的胫神经进行了评估:运动神经传导研究(MNCS)、超强重复神经刺激(SRNS)、F波和脊髓背电位(CDP)。传导速度、近端和远端复合肌肉动作电位的值以及MNCS的波幅分别为63.25±7.56米/秒、10.79±2.75毫伏和13.02±3.41毫伏。低频SRNS时第9波复合肌肉动作电位的波幅和面积的平均递减率分别为0.3±3.83%和0.1±3.51%。F波的最小潜伏期和F比率分别为8.49±0.65毫秒和1.92±0.17。CDP的起始潜伏期为1.99±0.03毫秒。这些测试可能有助于诊断神经肌肉疾病,并更好地描述许多患有全身性疾病的雪貂所报告的后肢轻瘫。
