Effects of ginger moxibustion combined with Tongyuan acupuncture on clinical symptoms and surface electromyography in patients with chronic lumbar muscle strain of cold-dampness type

目的观察隔姜灸联合通元针法对寒湿型慢性腰肌劳损患者临床症状及表面肌电图的影响。方法将96例寒湿型慢性腰肌劳损患者按照随机数字表法分为2组,对照组48例予通元针法,治疗组48例在对照组治疗基础上联合隔姜灸,治疗时间为隔日1次,共治疗22天。比较2组治疗前后临床症状积分、日本骨科协会(JOA)腰椎评分量表、简化McGill疼痛问卷量表(SF-MPQ)、Oswestry功能障碍指数评定量表(ODI)及表面肌电图[肌肉表面肌电的均方根值(RMS)和中位频率(MF)]变化。结果2组治疗后临床症状活动不利、腰部压痛程度、压痛点个数评分均较本组治疗前降低(P<0.05),且治疗组治疗后均低于对照组(P<0.05)。2组治疗后SF-MPQ各单项评分均较本组治疗前降低(P<0.05),且治疗组治疗后均低于对照组(P<0.05)。2组治疗后JOA腰椎评分量表评分均较本组治疗前升高(P<0.05),且治疗组治疗后高于对照组(P<0.05),2组治疗后ODI评分均较本组治疗前降低(P<0.05),且治疗组治疗后低于对照组(P<0.05)。2组治疗后直立和弯腰状态下表面肌电RMS及MF值均较本组治疗前降低(P<0.05),且治疗组治疗后均低于对照组(P<0.05)。结论隔姜灸结合通元针法能有效改善寒湿型慢性腰肌劳损患者临床症状,减轻患者疼痛,提高腰部功能,改善竖脊肌肌张力。

Objective To study the improvement effect of ginger moxibustion combined with Tongyuan acupuncture on clinical symptoms and surface electromyography(sEMG)in patients with chronic lumbar muscle strain of cold-dampness type.Methods A total of 96 patients with chronic lumbar muscle strain of cold-dampness type were randomly allocated to treatment group(n=48)and control group(n=48).The patients of control group were given Tongyuan acupuncture,qod,for 22 days.The patients of treatment group were additionally given ginger moxibustion,qod,for 22 days.The clinical symptom scores,Japanese Orthopaedic Association Back Pain Evaluation Questionnaire(JOABPEQ),Oswestry Disability Index(ODI),short form of the McGill Pain Questionnaire(SF-MPQ),and the values of root mean square(RMS)and median frequency(MF)of sEMG were included as comparisons between groups before and after treatment.Results After treatment,scores of clinical syndromes(body adverse events,degree of waist tenderness,number of tenderness points)in the both groups were significantly lower than those before treatment(P<0.05),which in the treatment group were more pronounced(P<0.05).The scores of SF-MPQ,ODI in the both groups were significantly lower than those before treatment(both P<0.05),the decrease in the treatment group was more common(both P<0.05).The score of JOABPEQ in the both groups was significantly higher than that before treatment(P<0.05),there was significant difference in JOABPEQ between the treatment group and the control group(P<0.05).The values RMS and MF of sEMG were significantly lower than those before treatment(P<0.05),and which were more prevalent in the treatment group(P<0.05).Conclusion For patients with chronic lumbar muscle strain of cold-dampness type,the application of ginger moxibustion combined with Tongyuan acupuncture can effectively improve clinical symptoms,alleviate pain,improve waist function and activate tension of erector spinae muscle.
