目的:观察某部新兵不同强度军事训练前后胫骨骨膜厚度变化及临床症状。方法:将整群抽取的某两栖作战部队新兵90例,随机分为对照组,一般强度军事训练组和高强度军事训练组各30例。采用磁共振扫描技术检测新兵在军事训练前和经不同强度军事训练后第15、30、45和60天胫骨中下1/3处骨膜厚度变化;同时发放问卷调查表,对出现胫前区疼痛、肿胀或包块等临床症状的累计发生率进行统计。结果:胫骨骨膜厚度对照组军事训练前后差异不显著(P>0.05);一般强度和高强度军事训练组在军事训练后第15、30、45和60天显著厚于对照组(P<0.05);高强度军事训练组在军事训练后第30、45和60天显著厚于一般强度军事训练组(P<0.05)。高强度军事训练易导致胫前区出现疼痛、肿胀或包块等临床症状,其累计发生率有随军事训练强度和时间的增加而增高的趋势。结论:高强度军事训练易导致胫骨骨膜厚度增厚;随着军事训练强度和时间的增加,疼痛、肿胀或包块等发生率有增高的趋势。
Objective: To observe the changes of tibial periosteal thickness and clinical symptoms before and after military training of different recruits. Methods: A total of 90 amphibious units recruited from the cluster were randomly divided into control group, general strength military training group and high intensity military training group. The magnetic resonance scanning technique was used to detect the change of periosteal thickness of the recrudescents before and after military training on the 15th, 30th, 45th, and 60th days of the tibia. At the same time, the survey questionnaire was used to evaluate the anterior tibial area pain , Swelling or mass clinical symptoms such as the cumulative incidence of statistics. Results: There was no significant difference in the thickness of tibia before and after military training in the control group (P> 0.05). The general intensity and high strength military training group was significantly thicker than the control group on the 15th, 30th, 45th and 60th days after military training (P <0.05) ; The high-intensity military training group was significantly thicker than the general-intensity military training group on the 30th, 45th and 60th days after military training (P <0.05). High-intensity military training tends to lead to clinical symptoms such as pain, swelling or mass in the anterior tibial region. The cumulative incidence tends to increase with the intensity and time of military training. CONCLUSION: High-intensity military training easily leads to thickened periosteal thickness of the tibia. As the strength and time of military training increase, the incidence of pain, swelling or mass tend to increase.
