表面肌电图在腰痛患者ODI指数和JOA评分评估中的临床应用

Clinical Application of Surface Electromyography in Evaluation of ODI Index and JOA Score in Patients with Low Back Pain

目的:探讨表面肌电图在腰痛患者腰椎Oswestry功能障碍指数(ODI)和日本骨科协会评估治疗分数(JOA)评估中的临床应用。方法:选择2019年6月至2020年6月我院接诊的80例腰痛患者进行研究,通过将患者按照腰部VAS评分的不同划为对照组(VAS评分≤5分)和观察组(5分<VAS评分<10分),每组各40例,两组患者均接受接受常规治疗和肌电仪检测。比较治疗前后两组患者运动传导速度(MCV)、股神经的感觉传导速度(SCV)、动作电位的潜伏期、长肌力(IMS)、腰背肌后伸活动度(ROM)、ODI指数和JOA评分的变化情况。结果:治疗后,观察组运动传导速度、股神经的感觉传导速度指标水平均低于对照组,动作电位的潜伏期长于对照组(P<0.05);观察组长肌力、腰背肌后伸活动度指标水平均低于对照组(P<0.05);观察组Oswestry功能障碍指数(ODI)高于对照组,日本骨科协会评估治疗分数(JOA)评分低于对照组(P<0.05)。结论:腰痛患者中存在着明显的表面肌电图信号改变,且随着腰痛程度的加剧,改变程度越明显,有助于评估患者病情。

Objective:To explore the clinical application of surface electromyography in the evaluation of the Oswestry dysfunction index(ODI)of the lumbar spine in patients with low back pain and the Japanese Orthopaedic Association Evaluation Treatment Score(JOA).Methods:80 patients with low back pain who were admitted to our hospital from June 2019 to June 2020 were selected for the study.The patients were according to the difference of waist VAS score,the patients were divided into a control group(VAS score≤5 points)and an observation group(5 points<VAS score<10 points),40 cases in each group,patients in both groups received conventional treatment and electromyography.Comparison of motor conduction velocity(MCV),sensory conduction velocity of femoral nerve(SCV),latency of action potential,long muscle strength(IMS),range of motion(ROM),ODI index and JOA before and after treatment Change in score.Results:After treatment,the observation group's motor conduction velocity and femoral nerve sensory conduction velocity index levels were lower than those of the control group,and the latency of action potentials was longer than that of the control group(P<0.05);the long muscle strength and back extension activity index levels of the observation group were lower than those of the control group(P<0.05);the Oswestry Dysfunction Index(ODI)of the observation group was higher than that of the control group,and the Japanese Orthopaedic Association's Evaluation Treatment Score(JOA)score was lower than that of the control group(P<0.05).Conclusion:There are obvious changes in surface electromyography signals in patients with low back pain,and as the degree of low back pain intensifies,the more obvious the changes are,which helps to evaluate the patient's condition.
