    [摘要] 目的 探讨电流感觉阈值(CPT)测定对三叉神经痛患者感觉定量的评估作用。 方法 选择2017年1月—2018年10月江西省人民医院神经内科住院部或门诊临床确诊为原发性三叉神经痛下颌支受累的患者26例，所有患者均常规给予营养神经的药物治疗。在治疗前、治疗后7、14 d对患者进行CPT测定和简化麦吉尔(McGill)疼痛问卷评分表(SF-MPQ)测评，比较CPT和SF-MPQ疼痛评分，评价CPT在三叉神经痛患者治疗前后的感觉功能中的应用价值。 结果 治疗前用5、250 Hz刺激，患侧CPT高于健侧，差异均有统计学意义(均P 0.05)。患侧治疗后7、14 d CPT与治疗前比较，5、250 Hz刺激下的CPT均有所下降，差异均有统计学意义(均P 0.05)。治疗后7、14 d SF-MPQ疼痛评分低于治疗前，差异均有统计学意义(均P 0.05). CPT at 7 and 14 days after treatment on the affected side decreased under 5 and 250 Hz stimulation compared with before treatment， and the differences were statistically significant (all P 0.05). The pain score of SF-MPQ at 7 and 14 days after treatment was lower than that before treatment， and the differences were statistically significant (all P < 0.05). Pearson correlation analysis showed that SF-MPQ pain score at 7 and 14 days after treatment was positively correlated with CPT under 5 Hz stimulation of the affected mandibular branches (r = 0.656 ......
