目的:观察腰部支撑器对装甲车乘员腰痛的预防效果。方法:选择参加训练的装甲车乘员300例,随机分为观察组和对照组各150例,观察组在训练过程中全程使用腰部支撑器,对照组不使用;分别在训练前后填写功能障碍指数表(ODI)及视觉模拟疼痛量表(VAS),并对两组结果进行对比分析。结果:观察组训练前ODI平均分值5.86分,VAS平均分值1.89分;训练中及训练后出现显著腰痛21例,因腰痛中断训练2例,ODI平均分值7.26分,VAS平均分值2.34分。对照组训练前ODI平均分值5.88分,VAS平均分值1.87分;训练中及训练后出现显著腰痛54例,因腰痛中断训练15例,ODI平均分值11.05分,VAS平均分值6.40分。观察组训练后ODI、VAS评分显著低于对照组(P<0.05)。结论:使用腰部支撑器对装甲车乘员腰痛有较好的预防效果。 Objective: To observe the preventive effect of lumbar support on the low back pain of armored vehicle occupants. Methods: 300 armored vehicle occupants who participated in the training were randomly divided into observation group and control group with 150 cases in each group. The observation group received lumbar supporter during the whole training and the control group was not used. Fill out the dysfunction index table before and after training ODI) and visual analogue pain scale (VAS). The results of two groups were compared and analyzed. Results: The average score of ODI before training was 5.86 and the average score of VAS was 1.89. In training and training, there were 21 cases of significant back pain and 2 cases of back pain interruption training. The ODI average score was 7.26 and the VAS average score was 2.34 Minute. The control group had an ODI score of 5.88 before training and an average VAS score of 1.87; 54 patients had significant back pain during and after training, 15 received training due to low back pain, and had an ODI average score of 11.05 and a VAS average score of 6.40. The scores of ODI and VAS in observation group were significantly lower than those in control group (P <0.05). Conclusion: The use of lumbar support for armored vehicle occupants with low back pain has a better preventive effect.
