经皮神经电刺激和红外偏振光联合应用对老年带状疱疹后神经痛的影响

Effects of combination of TENS and laser on post-herpetic neuralgia in elders

目的 :探讨经皮神经电刺激 (TENS)和红外偏振光联合应用对老年带状疱疹后神经痛的疗效。方法 :将 4 5例PHN患者随机分为 3组 ,每组 15例。Ⅰ组使用TENS ;Ⅱ组使用红外偏振光治疗仪 ;Ⅲ组联合应用以上两种治疗方法。各组治疗每日 1次 ,每次各 30min ,10次一个疗程。使用疼痛视觉模拟评分法 (VAS)评估疼痛缓解程度 ;使用汉密顿抑郁量表 (HAMD)和汉密顿焦虑量表 (HAMA)进行治疗前后心理测验。结果 :治疗后VAS评分Ⅲ组和Ⅰ组与Ⅱ组相比较 ,差异具有显著性 (P <0 .0 5 ) ;HAMD和HAMA量表治疗前后各组自身对照差异显著 (P <0 .0 5 ) ,3组之间差异无显著性 (P >0 .0 5 )。结论 :TENS和红外偏振光治疗仪联合应用对老年PHN止痛效果好 ,可改善患者抑郁、焦虑症状 ,无任何副作用。

Objective: To investigate the effects of combination of transcutaneous electrical nerve stimulation (TENS) and laser in the treatment of post-herpetic neuralgia (PHN) in the elders. Method: 45 patients with PHN were randomly assigned to one of three groups (15 in each group) : TENS (Ⅰ group),Laser (Ⅱ group),combination of TENS and (Ⅲ group). Each group was treated one time a day, each time 30 minutes. 10 times is a period of treatment. Visual analogue scales (VAS) was utilized to assess the degree of pain. And Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA) were used to evaluate the psychological state before and after treatment. Result: There are significant differences between Ⅲ group and Ⅱ group and between Ⅱ group and Ⅰ group ( P <0.05) in VAS after a course of treatment. There was a significant difference between before and after treatment in each group ( P <0.05), but no significant difference between three groups in HAMD and HAMA ( P >0.05). Conclusion:Combination of TENS and Laser is an effective approach in treatment of PHN in the elders. It can improve the symptom of depression and anxiety, and it has no adverse effect on patients.
