超声引导下针刀松解激痛点治疗腰背肌筋膜疼痛综合征临床观察

Clinical Effect of Ultrasound-guided Acupotomy at Myofascial Trigger Points in Treatment of Lumbodorsal Myofascial Pain Syndrome

目的观察超声引导下针刀松解激痛点治疗腰背肌筋膜疼痛综合征(myofascial pain syndrome,MPS)的临床疗效。方法将60例腰背MPS患者随机分为常规组和超声组,每组30例。常规组采用普通针刀疗法进行治疗,超声组在超声引导下行针刀疗法治疗,两组均每周治疗1次,连续治疗4次为1个疗程。分别于治疗前后采用简化McGill疼痛问卷(short-form McGill pain questionnaire,SF-MPQ)评估患者疼痛程度,采用多裂肌杨氏模量值评估患者肌肉状态变化,并于治疗后观察两组临床疗效。结果与治疗前比较,两组患者治疗后SF-MPQ评分及杨氏模量值均显著降低(P<0.05);与常规组比较,超声组SF-MPQ评分及杨氏模量值降低程度更显著(P<0.05);超声组临床疗效显著优于常规组(P<0.05)。结论超声引导下针刀松解激痛点治疗腰背MPS,能显著缓解患者疼痛症状,显著改善肌肉组织弹性。

Objective To investigate the clinical effect of ultrasound-guided acupotomy at myofascial trigger points in the treatment of lumbodorsal myofascial pain syndrome(MPS).Methods A total of 60 patients with lumbodorsal MPS were randomly divided into ultrasound group and conventional group,with 30 patients in each group.The patients in the conventional group were treated with conventional acupotomy,and those in the ultrasound group were treated with ultrasound-guided acupotomy,once every week,with four consecutive treatment sessions as one course.Short-form McGill pain questionnaire(SF-MPQ)was used to evaluate the degree of pain before and after treatment,the Young s modulus value of multifidus muscle was used to evaluate the changes in muscle status,and clinical outcome was observed for both groups after treatment.Results After treatment,both groups had significant reductions in SF-MPQ score and Young s modulus value(P<0.05),and compared with the conventional group,the ultrasound group had significantly greater reductions in SF-MPQ score and Young s modulus value(P<0.05).The ultrasound group had a significantly better clinical outcome than the conventional group(P<0.05).Conclusion In the treatment of patients with lumbodorsal MPS,ultrasound-guided acupotomy at myofascial trigger points can significantly alleviate pain and improve muscle elasticity.
