体外冲击波治疗网球肘的镇痛效果研究

摘要

Objective: To study the analgesia effect of extracorporeal shock wave therapy (ESWT) in tennis elbow. Method: Forty-five patients with persistent tennis elbow received 3 times ESWT with 5 days intervals. The analgesia effect was assessed by present pain intensity (PPI), visual analogue scale (VAS) and Mills sign at the same day before and after treatment, and 1 week later of the last time treatment.Result: The analgesia effect after each treatment was obviously excellent than that before each treatment(P < 0.001). At the intermission the pain increased, the PPI scores before next treatment were higher than that of former post-treatment (P < 0.001), but were lower than that of former pre-treatment (P < 0.001). At 1 week follow-up, the PPI scores and VAS scores decreased from (2.29 ± 0.76) to (0.74 ± 0.52) and (5.06 ±1.51) to (1.99 ± 1.82) respectively, the positive rate of Mills sign decreased from 95.6% to 33.3%.Conclusion: ESWT has significantly immediate analgesia effect and accumulation effect of repeated treatment for tennis elbow.%目的:探讨体外冲击波治疗网球肘的即刻镇痛效应及累积效应.方法:使用国产电磁式体外冲击波治疗机治疗45例网球肘患者,5日1次,共3次.分别在每次治疗前、治疗后、疗程结束后1周,采用现时疼痛状况(PPI)、视觉模拟量表(VAS)、Mills征评定进行疗效评价.结果:3次治疗后即刻均比治疗前疼痛程度显著降低,差异有显著性意义(P＜ 0.001).在治疗间歇期,疼痛较上次治疗后即刻增加,差异有显著性意义(P＜ 0.001),但均比上次治疗前的疼痛程度低(P＜ 0.001),疗程结束后疼痛程度显著减轻,由治疗前的(2.29±0.76)分降到治疗后的(0.74±0.52)分.治疗后VAS评分比上次评定均有显著改善,由治疗前的(5.06±1.51)分降到治疗后的(1.99±1.82)分.治疗前Mills征阳性率为95.6％,3次治疗后阳性率分别为86.7％、64.4％、33.3％,差异有显著性意义(P＜ 0.001).结论:体外冲击波治疗网球肘具有显著的即刻镇痛效果,多次治疗后的镇痛作用有累积效应.
