问题陈述
有必要对下颌下牙槽神经进行快速、客观、定量的感觉测试，以评估由于创伤、感染或疾病造成的感觉障碍。
目的
本研究评估了一种商品化的电诊断定量感觉神经传导阈值(SNCT)评估测试方法的可靠性和可重复性，并为未来神经功能障碍的评估建立了标准值。
材料和方法
使用Neuroeter CPT/C获得快速电流感知阈值(R-CPT)，这是一种电诊断SNCT设备，在0.001~10 mA的强度范围内执行交流恒流正弦波形刺激，频率分别为2,000赫兹(赫兹)、250赫兹(M)或5赫兹(L)。对34名健康受试者进行测试，然后由同一操作员从7天到153天进行复测。使用双一次性镀金电极和使用非导电胶带固定到位的低致敏性电极凝胶对两侧颧孔进行R-CPT评估。对于每个刺激频率，获得两个连续相同的R-CPT测量，以确定最终的R-CPT值。
结果
在左侧，第一次测试和第二次测试之间没有差异(P>；0.05)。在右侧，L、M和H的第一次和第二次测试有统计学差异，但可信区间很窄，差异不具有临床意义。
结论
从所获得的数值来看，R-CPT测试对于量化健康个体的感觉功能是可靠的。
STATEMENT OF PROBLEM
There is a need for a quick, objective, quantitative sensory test of the mandibular inferior alveolar nerve to assess sensory dysfunction due to trauma, infection, or disease.
PURPOSE
This study evaluated the reliability and reproducibility of a commercially available electrodiagnostic quantitative sensory nerve conduction threshold (sNCT) evaluation testing method and established normative values for future evaluation of nerve dysfunction.
MATERIAL AND METHODS
Rapid current perception threshold (R-CPT) values were obtained with Neurometer CPT/C, an electrodiagnostic sNCT device that administers an alternating constant-current sinusoid waveform stimulus at either 2000 Hz (H) (Hertz [cycles/second]), 250 Hz (M), or 5 Hz (L) at intensity levels ranging from 0.001 to 10 mA. Thirty-four healthy subjects were tested then retested by the same operator from 7 days to 153 days. R-CPT evaluation was performed over the mental foramen bilaterally with dual disposable gold-plated electrodes and a hypoallergenic electrode gel held in place using nonconductive adhesive tape. Two consecutive identical R-CPT measures were obtained for each stimulation frequency for determination of the final R-CPT value.
RESULTS
On the left side, there was no difference between the first and second test (P > .05). On the right side, there was a statistical difference between the first and second test for L, M, and H, but the confidence interval is very narrow and the differences are not clinically significant.
CONCLUSION
From the values obtained, R-CPT testing was reliable for the quantification of sensory function in healthy individuals.
