重复经颅磁刺激仪辅助治疗脊髓损伤后中枢性疼痛患者的效果

Analysis of the Effect of Repetitive Transcranial Magnetic Stimulator in the Auxiliary Treatment of Central Pain after Spinal Cord Injury

目的 探讨重复经颅磁刺激仪辅助治疗脊髓损伤(SCI)后中枢性疼痛患者的效果。方法 选取2019年1月到2022年2月于医院骨科就诊的84例SCI后中枢性疼痛患者,以随机数字表分为两组,各42例。对照组予以综合性治疗,试验组在此基础上联用重复经颅磁刺激仪治疗,两组均治疗8周。比较两组治疗前后疼痛程度[疼痛感觉项总分(PRI-S),疼痛情感项总分(PRI-A)、现实疼痛指数(PPI)、视觉模拟评分法(VAS)]及日常生活能力(Barthel指数)的变化,并评估临床疗效。结果 治疗后,两组PRI-S、VAS及PPI评分较治疗前明显下降,且试验组低于对照组,差异有统计学意义(P<0.05);两组Barthel指数较治疗前明显上升,且试验组高于对照组,差异有统计学意义(P<0.05);试验组总有效率明显高于对照组,差异有统计学意义(P<0.05)。结论 重复经颅磁刺激仪辅助治疗SCI后中枢性疼痛的疗效确切,可降低疼痛程度,提高日常生活能力。

Objective The effect of repetitive transcranial magnetic stimulator in auxiliary treatment of central pain after spinal cord injury(SCI)was explored.Methods With selection of 84 patients with central pain after SCI treated in the orthopedics department of the hospital from January 2019 to February 2022,the patients were divided into two groups by random number table,with 42 patients in each group.The control group was treated with comprehensive treatment,and the experimental group was treated with repetitive transcranial magnetic stimulator on the basis of the control group.With 8 weeks of treatment in two groups,the changes of pain degree[pain rating index-S(PRI-S),pain rating index-A(PRI-A),present pain index(PPI),visual analogue scale(VAS)]and ability of daily living(Barthel index)in the two groups were compared before and after treatment,and the clinical efficacies were evaluated.Results After treatment,the scores of PRI-S,VAS and PPI in the two groups were significantly lower than those before treatment,and the experimental group was significantly lower than the control group(P<0.05);The Barthel index of the two groups was significantly higher than that before treatment,and the experimental group was higher than the control group,the differences were statistically significant(P<0.05);The total effective rate of the experimental group was significantly higher than that of the control group(P<0.05).Conclusion The repetitive transcranial magnetic stimulator is effective in the auxiliary treatment of central pain after SCI,which can significantly reduce the degree of pain and improve the ability of daily living.
