To investigate the effects of joint function screening and correction on intervention efficacy of prevention and assessment score of training injuries in new recruits.

A randomized controlled study was conducted on 265 new recruits subjected from two organizational units of an army unit with cluster sampling. Based on entire organizational unit, the participants were randomly divided into a control group (n=132) and an experimental group (n=133). The experimental group received joint function screening and corrective movement training, which was subsequently applied in the new recruit training, while the control group underwent training according to conventional methods. Joint function were collected before and after training. The demographic data, assessment score of training, and incidence of training injuries were collected through the participant’s own organizational unit. Receiver operating characteristic (ROC) curve was plotted to evaluate the efficacy of joint function screening in predicting training injuries, and binary logistic regression and general linear regression analyses were applied to verify the correlation of joint function screening score with training injuries and assessment score of training.

After new training, the score of joint function screening was significantly higher in the experimental group than the control group (16.62±1.87 vs 14.92±2.58, P<0.001). And the score was obviously increased in the experimental group (16.62±1.87 vs 12.82±1.98, P<0.001) and the control group (14.92±2.58 vs 12.95±1.81, P<0.001) when compared with the corresponding score before training. The area under the ROC curve (AUC) of joint function screening in predicting training injuries was 0.762 (95%CI: 0.694~0.830), indicating good predictive efficacy. During the new training process, the incidence of training injuries in the experimental group (13.53%) was significantly lower than that in the control group (24.24%, Chi-square =4.963, P=0.026). Binary logistic regression analysis showed that the pre-training assessment score of joint function screening was an important influencing factor for training injuries in new recruits (OR=0.552, 95%CI: 0.413~0.660, P<0.001). The experimental group obtained notably higher mean assessment score than the control group [733.00 (716.00, 752.75) vs 728.79 (710.46, 744.28), P=0.027]. Linear regression analysis revealed a correlation between post-training score of joint function screening and the assessment score of newly trained personnel (P<0.001).

Joint function screening and correction for newly trained personnel can effectively prevent training-related injuries during the new training period, and correcting joint function through training can effectively improve the assessment score of newly trained personnel.

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.

To identify recruit movement dysfunction based on military joint function screening and assessment, implement targeted corrective training, explore the impact of this assessment-correction system on knowledge-attitude-belief-practice (KABP) related factors, and scientifically evaluate its efficacy in preventing recruit military training injuries within the knowledge-attitude-belief-practice theoretical framework.

A cluster randomized controlled trial was conducted at a recruit training base of the Joint Logistics Support Force from March to May 2025, enrolling 446 recruits. Participants were randomly assigned to an experimental group (n=223) or control group (n=223) using a random number table. The control group followed the routine training program, while the experimental group additionally received a 2-month targeted corrective training for movement dysfunction alongside the established training tasks. Knowledge-attitude-belief-practice questionnaires were administered to both groups at the initial, intermediate, and advanced stages of the corrective training. Univariate logistic regression was used to preliminarily screen KABP-related factors, and a multivariate logistic regression model was further constructed to analyze the role of KABP factors in the corrective training.

The experimental group had a cumulative training injury incidence of 40 cases (17.9%), which was significantly lower than that of the control group (83 cases, 37.2%; χ² =20.757, P<0.001). The experimental group showed varying degrees of improvement in knowledge, attitude and belief, and practice dimensions (P<0.05), while the control group exhibited no significant changes in the three KABP dimensions across the three surveys. Logistic regression analysis revealed: In the first round, total practice score was significantly negatively associated with training injury incidence rate (OR=0.863, 95%CI: 0.822~0.906, P<0.001), whereas knowledge and attitude-belief dimensions showed no significant association; In the second round, both total knowledge score (OR=0.925, 95%CI: 0.903~0.946, P<0.001) and total practice score (OR=0.906, 95%CI: 0.874~0.940, P<0.001) significantly reduced the risk of military training injuries, with attitude-belief dimension still showing no significant effect; In the third round, all three KABP dimensions were significantly negatively associated with military training injury incidence rate (knowledge: OR=0.905, 95%CI: 0.884~0.926, P<0.001; attitude and belief: OR=0.942, 95%CI: 0.899~0.988, P=0.013; behavior: OR=0.882, 95%CI: 0.841~0.924, P<0.001).

Joint function screening and corrective training can significantly reduce the incidence of recruit training injuries, primarily by optimizing knowledge mastery and movement behavior; belief cultivation, however, requires long-term practical accumulation.
