体外冲击波治疗运动员NLBP的即刻镇痛效应研究

Study on the immediate analgesic effect of extracorporeal shock wave therapy for NLBP in athletes

目的:通过应用体外冲击波技术探究其对运动员慢性非特异性下背部疼痛即刻镇痛效应的有效性以及安全性。方法:将60例诊断为慢性非特异性下背痛的运动员随机分为ESWT组(n=30)和对照组(n=30),分别给予冲击波治疗和磁振热治疗。冲击波治疗应用于运动员下背部压痛点处,治疗压力为1.8-2.5 bar,频率8.0-10.0 Hz,冲击剂量2000次。分别在治疗前、治疗后以及次日起床7点应用疼痛视觉模拟评分(VAS)对两组运动员进行腰部疼痛评价。结果:ESWT组中运动员在治疗后即刻以及次日起床7点VAS评分均有降低,对照组在治疗后即刻VAS评分有所降低,治疗后即刻两组间指标存在显著差异(P<0.05),治疗后次日ESWT组指标优于对照组(P<0.05)。结论:体外冲击波能够即刻减轻运动员非特异性下背痛,且治疗效果能够延续一定时间。

Objective:To investigate the efficacy and safety of the immediate analgesic effect of extracorporeal shock wave therapy on chronic non-specific lower back pain in athletes.Methods:Sixty athletes with chronic non-specific lower back pain were randomly divided into ESWT group(n=30)and control group(n=30),and given extracorporeal shock wave therapy and magnetic vibration heat therapy,respectively.Extracorporeal shock wave therapy applied to the painful points of the lower back in athletes,treatment pressure was set to 1.8-2.5 bar,frequency 8.0-10.0 Hz,and shock 2000 times.The visual analogue score of pain(VAS)was applied to evaluate low back pain in both groups of athletes before treatment,after treatment,and at 7:00 a.m.on the following day,respectively.Results:In the ESWT group,the athletes'VAS scores decreased in the immediate post-treatment period and decreased in the following day,while in the control group,the VAS scores only decreased in the immediate post-treatment period,and there was a significant difference between the two groups immediately after the treatment(P<0.05),and the ESWT group had better VAS scores than the control group the next day after treatment(P<0.05).Conclusions:Extracorporeal shock waves provide immediate relief of non-specific lower back pain in athletes,and the therapeutic effect can be sustained over time.
