【摘要】：探讨训练性下腰痛患者的躯干肌力、腰椎曲度及骶棘肌横截面积的变化 ,应用CYBEX 6 0 0 0型等速测试训练系统测试腰痛组和正常组各 4 0名的躯干肌力指标 ,并在立位腰椎侧位X线片上测量腰椎曲度 ,应用彩超测量骶棘肌横截面积 ,两组间进行比较。结果显示 ,躯干屈肌PT/BW腰痛组与正常组无显著性差异 ,TAE则腰痛组低于正常组(P 0 0 5 ) ,而躯干伸肌PT/BW和TAE腰痛组均低于正常组 (P 0 0 5 ) ;腰痛组的F/E大于正常组 (P 0 0 5 ) ,腰椎曲度小于正常组 (P 0 0 5 ) ,骶棘肌横截面积与正常组无显著性差异。提示训练性下腰痛者存在着明显的腰背肌力下降 ,以及由此所致的躯干肌肌力失衡、腰椎生理曲度变直 ,但并不伴有明显的椎旁肌萎缩
[Abstract]:To investigate the changes of trunk muscle strength, lumbar curvature and sacral spine muscle cross-sectional area in patients with training low back pain, the trunk muscle strength indexes of 40 patients with low back pain and 40 normal subjects were measured by CYBEX 6000 isokinetic training system. The curvature of lumbar vertebrae was measured on the lateral X-ray film and the cross sectional area of sacrospinalis muscle was measured by color Doppler ultrasound, and the comparison was made between the two groups. The results showed that there was no significant difference between the trunk flexor muscle PT/BW group and the normal group (P < 0.05), but the PT/BW and TAE low back pain group in trunk extensor muscle group were lower than those in the normal group (P 0.05). The F- / E of lumbago group was higher than that of normal group (P 0 05), and the curvature of lumbar vertebrae was lower than that of normal group (P 0 05). There was no significant difference in cross sectional area of sacral spine muscle between the two groups. It is suggested that there is a significant decrease in the muscle strength of the lumbar dorsal muscle in the patients with training low back pain, and the imbalance of the muscle strength of the trunk resulting from this, and the straightening of the physiological curvature of the lumbar vertebrae, without obvious atrophy of the paravertebral muscles.
