【摘要】：为探讨训练性下腰痛患者躯干肌功能变化 ,分别应用CYBEX 6 0 0 0型等速测试训练系统、彩超、肌电图、立位腰椎侧位X线片测试腰痛组(n=4 0 )和正常组 (n =4 0 )的躯干肌力指标、骶棘肌横截面积、腰背肌肌电指标及腰椎曲度。结果显示 ,在腰痛组与正常组 ,除躯干屈肌PT/BW、ER及骶棘肌横截面积差异无统计学意义 (P 0 0 5 )外 ,其他指标相比差异均有统计学意义(P 0 0 5 )。提示由于缺乏有效的腰背肌锻炼 ,训练性下腰痛患者存在明显的躯干肌肌力失衡 ,其主要由腰背肌肌力下降引起 ;同时腰背肌肌爆发力以及腰背肌静态耐力也明显下降 ,腰椎生理曲度变小 ,但不伴随有明显的椎旁肌萎缩 ;耐力比ER(动态耐力)与下腰痛关系并不密切。同时在此基础上设计了预防训练性下腰痛的现场干预实验 ,结果显示训练性下腰痛发生率明显降低 (锻炼组 8 93% ,对照组 17 0 1% ,P 0 0 1)。提示腰背肌锻炼可降低训练性下腰痛的发生率。
[Abstract]:In order to investigate the changes of trunk muscle function in patients with training low back pain, CYBEX 6000 isokinetic training system, color Doppler ultrasound and electromyography were used. The trunk muscle strength index, sacrospinalis cross sectional area, lumbar dorsal myoelectric index and lumbar curvature were measured in the lateral position of lumbar vertebrae (n = 40) and normal group (n = 40). The results showed that there was no significant difference in the cross sectional area of the trunk flexor and sacral spine between the patients with low back pain and those in the normal group, except that there was no significant difference in the cross sectional area of the torso flexor and the sacral spine (P 0 05). It is suggested that due to the lack of effective lumbar muscle exercise, there is obvious imbalance of trunk muscle strength in patients with training low back pain, which is mainly caused by the decrease of lumbar dorsal muscle strength. At the same time, the explosive force of lumbar dorsal muscle and static endurance of lumbar dorsal muscle also decreased obviously, the physiological curvature of lumbar vertebrae became smaller, but there was no obvious atrophy of paravertebral muscle, and the relation between endurance ratio (dynamic endurance) and lower back pain was not close. At the same time, a field intervention experiment was designed to prevent low back pain caused by training. The results showed that the incidence of low back pain in training group (8.93%) was significantly lower than that in control group (17.01%). The results suggest that the training of lumbar dorsal muscle can reduce the incidence of low back pain.
