摘　　要：目的探讨肌力训练对下背痛患者胸腰椎生物力学的影响。方法分为观察组与对照组2组,观察组为2008年9月~2010年8月间本院门诊的50例下背痛患者,其中男24例,女26例,年龄50~70岁,平均（59.7±5.7）岁。对照组为50~70岁的正常人群,其中男23例,女27例,平均（61.1±5.6）岁。观察组进行肌力训练,每次40 min,每天2次,共12周。两组人员分别行在治疗或入组前、治疗后12周行胸腰椎X摄片,进行双能X线骨密度测试,采用测骨器测量胸腰椎相关形态检查,同时行疼痛视觉模拟评分（VAS）。结果与对照组相比,观察组治疗前腰椎前凸角、骶骨倾斜角均明显减少,2组差异显著（P〈0.05）,与治疗前相比,观察组治疗后腰椎曲度、骶骨倾斜角及骨密度均无显著差异（P〉0.05）,但治疗后观察组患VAS评分明显下降（P〈0.05）。结论 肌力训练对下背痛患者的胸腰椎生物力学改变有积极的影响,并能缓解疼痛。Objective To investigate the biomechanical effect of muscle strength training on low back pain patients.Methods Two groups included observation group and control group.The observation group included 50 patients with lumbago in outpatient department from September 2008 to August 2010.Observation group included 24 male,and 26 female patients from 50 to 70 years old with mean（59.7±5.7） years.The control group included 23 male and 27 female with mean（61.1±5.6） years old.The patients of observation group accepted rehabilitation therapy such as strength training,physical therapy,et al.40 min/time,twice a day,12 weeks.Before and after treatment,all the patients of the two groups examined thoracolumbar by X-ray film,bone mass density test by Dual energy X ray,related form of thoracic and lumbar by measuring bone.Results Compared with the control group,both the fore-lumbar curvature and sacral inclination angle decreased,the difference is significant（P〈0.05）.Compared with the initial,there was no significant difference of lumbar curvature,sacral inclination angle and bone mass density in observation group（P〈0.05）,but there is a significant decrease of visual analogue scale（VAS） in observation group.Conclusion Muscle strength training has good effect on patients with low back pain andcan help relieve the degree of pain.
