摘　　要：背景:研究表明通过表面肌电测试,非特异性慢性下腰痛患者腰部脊柱两侧竖脊肌活动的变化不一致。在体质测量评价中侧重对腰部整体力量的测评,对青少年椎旁肌的测评方法和指标并未有研究报道。目的:拟建立评定青少年椎旁肌耐力及左右侧对称性的方法和指标,初步制定评价等级标准。方法:于北京市某中学随机抽取200名学生,其中初中生100名,高中生100名;年龄13-18岁,男女各半。受试者采用Biering-Sorensen(B-S)实验动作,保持椎旁肌等长收缩,采用表面肌电技术记录L3-L4双侧竖脊肌、L5-S1双侧多裂肌肌电,上身无法维持水平姿势或经3次提醒仍低于水平位时停止测试。筛选指标并建立评价指数,按离差法确定各年龄段椎旁肌耐力及左右侧对称性评价等级标准。研究方案的实施符合北京体育大学的相关伦理要求,受试者及其监护人对试验过程完全知情同意。结果与结论:①根据解剖姿势分析和肌肉动员比测试,确定B-S动作左/右竖脊肌、左/右多裂肌为原动肌;肌电指标平均功率频谱随时间延续线性下降(R<-0.97,P<0.01);重复性检验,平均功率频谱斜率(Slope MPF)差异检验P>0.05,组内相关系数ICC>0.80(P<0.01),SlopeMPF重复性良好;②拟合复合指数,椎旁肌耐力指数v=slope MPF(左竖脊肌+右竖脊肌+左多裂肌+右多裂肌)/4,评价青少年椎旁肌耐力;对称性指数u=slopeMPF(左竖脊肌-右竖脊肌)/slopeMPF(左竖脊肌+右竖脊肌)+slopeMPF(左多裂肌-右多裂肌)/slopeMPF(左多裂肌+右多裂肌),评价青少年椎旁肌左右侧对称性;③评价结果显示,同性别高中生较初中生椎旁肌耐力均有增加(P<0.01);高中组男、女生椎旁肌耐力具有显著性差异;青少年椎旁肌耐力及对称性测试结果均呈现正态分布并可利用离差法进行评价等级划分;④研究初步建立了评定椎旁肌耐力及左右侧对称性的指标和方法,并采用离差法初步制定青�BACKGROUND:Surface electromyography has indicated that non-specific chronic low back pain patients have inconsistent changes in the motion of erector spinae muscles on both sides of the lumbar spine.Existing physical fitness evaluation focuses on the evaluation of the overall strength of the waist,whereas there is no report on the evaluation methods and indicators of paravertebral muscle in teenagers.OBJECTIVE:To establish methods and indicators for assessing teenagers’paravertebral muscle endurance and left-right symmetry,and to preliminarily formulate evaluation criteria.METHODS:Two hundred students,aged 13-18 years,were randomly selected in a middle school of Beijing,half male and half female.There were 100 junior high school students and 100 high school students.All the subjects did Biering-Sorensen(B-S)exercise to maintain isometric contraction of paravertebral muscles,and surface electromyography was then used to record the electromyography of bilateral erector spine muscles(ES)of L3-L4 and multifidus muscles(MF)of L5-S1.Measurement was terminated when the upper body could not maintain the horizontal posture or was still below the horizontal position after three reminders.The indexes were screened and the evaluation indexes were established.The evaluation criteria of paravertebral muscle endurance and left-right symmetry of each age group were determined by the dispersion method.The study protocol was in line with the ethics requirements of Beijing Sport University.Subjects and their guardians were fully informed of the study process.RESULTS AND CONCLUSION:According to the anatomic posture analysis and muscle mobilization ratio test,the left/right erector spine muscle(LES/RES)and left/right multifidus muscle(LWF/RMF)in B-S action were confirmed to be the prime muscle.Mean power frequency(MPF)decreased linearly with time,and the correlation coefficient was R<-0.97(P<0.01).In terms of repeatability measurement,MPF slope(slopeMPF)difference test was defined as P>0.05,and correlation coefficient within the gr
