| 目的 探讨VHD型预定制矫形鞋垫是否可以降低海军新兵下肢过劳性损伤（LLOI）的发生率。方法 选取参加入伍训练的400名男性海军新兵，随机分配至试验组（n＝200）和对照组（n＝200）。在入伍训练期间，试验组穿着VHD型预定制矫形鞋垫，对照组不穿鞋垫。1周后进行问卷调查，对出现不良反应的新兵的矫形鞋垫进行重新塑形。12周后通过问卷调查和体格检查收集新兵健康资料。主要研究结果为新兵入伍训练期间LLOI的发生率，次要研究结果为新兵参加入伍训练发生LLOI的类型、因LLOI损失的训练时间、穿着矫形鞋垫的舒适度评分和不良反应。结果 试验组和对照组基线测量数据差异无统计学意义（P＞0.05）。共发生76例LLOI，其中试验组24例（12%）、对照组52例（26%）。最常见的LLOI类型为足底筋膜炎。试验组因LLOI损失的训练时间共为51 d（2.12 d/人），对照组则为123 d（2.37 d/人）。试验组穿着矫形鞋垫1周和12周后舒适度评分分别为（3.76±1.87）和（2.03±1.74）分；不良反应发生率分别为18%（36/200）和5%（10/200），最常见的不良反应为足弓疼痛。结论 VHD型预定制矫形鞋垫可降低新兵LLOI的发生率，减少因LLOI导致的训练时间损失，穿着舒适性较好，不良反应较少。 |

| Abstract: |
| Objective To investigate whether VHD prefabricated foot orthoses can reduce the incidence of lower limb overuse injury (LLOI) in naval recruits. Methods Totally 400 recruits who underwent enlistment training were enrolled and randomly assigned to the intervention group (n＝200) and control group (n＝200). During the enlistment training, the recruits in the intervention group wore VHD prefabricated foot orthoses, while those in the control group did not wear foot orthoses. Questionnaire survey was conducted 1 week later, and the foot orthoses of those recruits with adverse events were remoulded. The health data of recruits were collected again by questionnaire survey and physical examination 12 weeks later. The primary outcome was the incidence of LLOI. The secondary outcomes included the type of LLOI, the lost training time due to LLOI, the comfort score of the foot orthoses, and the adverse events. Results There were no significant differences in the baseline characteristics between the 2 groups (P＞0.05). A total of 76 cases of LLOI was recorded, including 24 cases (12%) in the intervention group and 52 cases (26%) in the control group. Plantar fasciitis was the most common type of LLOI. The lost training time of the intervention group and the control group were 51 d (2.12 d for each one) and 123 d (2.37 d for each one), respectively. The comfort scores of the foot orthoses at 1 week and 12 weeks were 3.76±1.87 and 2.03±1.74, respectively. The incidences of adverse events in 1 week and 3 months were 18% (36/200) and 5% (10/200), respectively. The most common adverse event was arch pain. Conclusion VHD prefabricated foot orthoses can reduce the incidence of LLOI and lost training time due to LLOI in recruits, with good wearing comfort and less adverse events. |
