谐振致装甲步兵肌源性下腰痛的调查与分析

Investigation & analysis on the armored infantry with nonspecific low back pain induced by resonance

目的对装甲步兵肌源性下腰痛的发生率进行分析,了解谐振对肌源性下腰痛的影响,以及腰背肌相对肌力训练对改善肌源性下腰痛的效果。方法采用自制调查表及拟定的肌源性下腰痛诊断标准,对某部402名装甲步兵肌源性下腰痛发生情况进行调查,比较不同专业和军龄战士肌源性下腰痛的发生率及疼痛程度;对肌源性下腰痛患者采取腰背肌相对肌力训练,比较其改善情况。结果该群体中下腰痛的患病率为12.93%,乘员发生率是20.36%,载员发生率是7.66%,这两部分人群发病率比较有统计学意义(P<0.001);Ⅰ度疼痛发生率8.21%,Ⅱ度疼痛3.98%,Ⅲ度以上的发生率0.75%,三种疼痛级别发生情况比较有统计学意义(P<0.05);腰背肌相对肌力训练后,A组(健康对照0干预组)有1例发生肌源性下腰痛;B组(健康对照干预组)没有肌源性下腰痛伤员发生,C组(0干预病例组)有19例症状缓解;D组(干预病例组)有24例症状缓解。结论装甲步兵是肌源性下腰痛高危人群;长期接触不良谐振是造成装甲步兵肌源性下腰痛重要危险因素;疼痛多为Ⅰ、Ⅱ度;腰背肌相对肌力训练对缓解肌源性下腰痛有效。

Objective To analyze the incidence of myogenic low back pain in the armored infantry, investigate the impact of resonance,as well as the effectiveness of back muscle strength training. Methods With the self-designed questionnaire and the diagnosis standard of myogenic low back pain,the findings of 402 cases of armored infantry undergoing resonance was investigated. The degree of the pain and incidence were compared in armored infantry with different specialty and enlist time. By performing back muscle strength training,the symptomatic relief was observed. Results The prevalence of low back pain in this population was 12.93%; 20.36% in occupant,7.66% in manning occurrence,so their the incidence had statistically difference （P〈0.001）; Also 8.21% with Ⅰ degree of pain,3.98% with Ⅱ degree,0.75% with III degree,so the incidence of the three degrees had statistical difference （P〈0.05）;Performing back muscle strength training, 1 case was of low back pain in group A （i.e health control non-intervention group）;Group B （i.e health control ＋ intervention group） had no low back pain patients,19 cases of group C （i.e case-group without intervention） had symptomatic relief,24 cases of Group D （i.e case-group with intervention） had symptomatic relief. Conclusion Armored infantry is a high- risk population of myogenic low back pain ;Resonance vibration is an important risk factor for myogenic low back pain in the armored infantry;Most of them with Ⅰor Ⅱ degree of pain; myogenic low back pain can be effectively lightened by back muscle strength training.
