Prevention effectiveness of motor dysfunction correction against training injuries in new recruits during recruit basic training: a randomized controlled study

To explore the prevention effectiveness of a mode, conducting targeted corrective training based on motor dysfunction detected by military joint function screening, on military training injuries in new recruits during recruit basic training in order to cope with the high incidence of military training injuries among them.

A military personnel joint function screening was conducted on the new recruits in a training base of Joint Logistics Support Force. Based on the results of screening, the new recruits with a single action score of 1 and a total score of <10 were subjected and served as corrective training participants. Through cluster sampling, the new recruits were randomly divided into an experimental group (n=223) and a control group (n=223). The control group were trained according to the regular training plan, while the experimental group completed their designated training tasks and a 2-month corrective training for motor dysfunction at the same time. The entire corrective training process was carried out by our key personnel who had received relevant training. Medical records of the medical security department of the experimental unit were collected and evaluated for the injury situation. The score of joint function screening was analyzed using independent sample t test. The incidence of training injuries was analyzed using Chi-square test or Fisher's exact test.

After corrective training, the score of joint function was higher in the experimental group than the score before training (15. 12±2. 13 vs 10. 58±2. 83), and the score was also higher than that of the control group (15. 12±2. 13 vs 14. 19±1. 97, P<0. 05). During the recruit basic training period, the incidence of training injuries was notably lower in the experimental group than the control group (12. 5% vs 34. 5%, Chi-square=5. 469, P=0. 001). Only for those who were injured during the training, 11 people (39. 2%) in the experimental group scored less than 10, which was obviously lower than the 49 people (63. 6%) in the control group (Chi-square=4. 972, P=0. 026).

Our mode, corrective training based on the results of military personnel joint function screening, can effectively reduce the incidence of military training injuries in new recruits during recruit basic training, and exerts a good preventive effect against military training injuries.
