目的 通过医学干预前后的比较研究，观察其对降低武警某部擒敌术训练伤发生的作用和效果。方法 整群抽取武警部队驻津某部802名官兵进行问卷调查，对象全部为参加过擒敌术训练的中队官兵。在实施医学干预1年后，调查干预前后的训练伤发生情况，然后进行比较分析。结果 擒敌术训练伤的发生率与发生原因在医学干预前后均有显著变化:干预后的训练伤发生率(6.7人次/100人年)比干预前的训练伤发生率有所(11.3人次/100人年)降低，差异有统计学意义(P<0.01);动作要领掌握不当在擒敌术训练伤发生的原因中所占的百分比，干预后(24.1%)与干预前(40.7%)比较，差异有统计学意义(P<0.05)。结论 在武警全训特勤部队擒敌术训练中，实施科学的医学干预可有效降低军事训练伤的发生。

Objective To observe the effectiveness of medical intervention in the incidence of capture technique training injuries in a troop of Chinese People’s Armed Police Forces (CAPF) in Northern China. Methods A training troop was chosen randomly and was treated with medical intervention. Investigation was carried out by questionnaire into the incidence of capture technique training injuries in one year before and after intervention. Then the data were compared by statistical analysis. Results Injuries in capture technique training were significantly influenced by medical intervention, with its incidence decreasing from 11.3 man-time/100 man year to 6.7 man-time/100 man year (P<0.01) and the percentage of main injury reasons decreasing from 40.7% to 24.1% (P<0.05). Conclusion Implementation of medical intervention can effectively reduce the incidence of injuries in capture technique training.
