督灸联合康复训练治疗腰肌劳损患者的临床效果及表面肌电评价

Clinical effects of combining moxibustion with rehabilitation training in patients with lumbar muscle strain by surface electromyographic evaluation

目的通过表面肌电信号评价督灸治疗腰肌劳损患者的临床效果.方法将110例腰肌劳损患者随机分成对照组(n=55)和试验组(n=55),对照组采用常规康复训练包括日常生活能力训练、俯卧位背身训练、仰卧位腹肌训练等,1次/d,共30次,假督灸治疗每周2次,共8次.试验组常规康复训练与对照组相同,督灸治疗每周2次,共8次.分别在治疗前后进行表面肌电均方根值(RMS)和中位频率(MF)、视觉模拟评分(VAS)、下腰痛评分(JOA)和下腰痛评分改善率进行评价,并在治疗结束后的1个月后进行随访,采用视觉模拟评分(VAS)、下腰痛评分(JOA)进行评价.结果治疗前两组患者的RMS、MF、VAS、JOA组间比较差异均无统计学意义(P>0.05).治疗后两组患者的上述指标均较治疗前明显改善(P<0.05).结论表面肌电信号可以作为客观评价指标评估督灸联合康复训练治疗腰肌劳损患者的临床效果.督灸联合康复训练能进一步缓解腰肌劳损患者的腰部疲劳、减轻疼痛,增加活动.

Objective To evaluate the clinical effect of acupuncture and moxibustion on patients with lumbar muscle strain by surface electromyography.Methods One hundred and one patients with psoas muscle strain were randomly divided into a control group(n=55)and an experimental group(n=55).The control group received routine rehabilitation training including daily living ability training,prone body training,supine abdominal muscle training,once a day for a total of 30 times,and Sham tuber moxibustion treatment twice a week for a total of 8 times.The routine rehabilitation training of the experimental group was the same as that of the control group.The root mean square(RMS)values,the median frequency(MF),visual analogue scale(VAS),and low back pain score(JOA)were evaluated before and after every treatment,as well as one month after the end of the treatment.Results Before treatment,there was no significant differences in RMS,MF,VAS or JOA between the two groups(P<0.05).After treatment,the above indexes in the 2 groups were significantly improved compared with before treatment(P<0.05).Conclusion Surface electromyography signal can be used as an objective evaluation index to evaluate the clinical effect of acupuncture and moxibustion in the treatment of patients with lumbar muscle strain.It can further relieve waist fatigue,reduce waist pain and increase waist activity.
