Abstract：Objective To explore the predictive validity of joint function screening combined with rating of perceived ex-ertion(RPE)for military training injuries(MTI)in recruits.Methods The data of 144 recruits recruited in a new training base were analyzed and the joint function and RPE screening were carried out after recruitment;the occurrence of MTI was diagnosed and counted by military doctors within 2 months of training,and the diagnostic efficacy,accuracy and clinical applicability of joint function screening and RPE in predicting MTI were evaluated.Results MTI occurred in 46 of 144 recruits,with an incidence of 31.94％.The scores of joint function screening scale and RPE of recruits with MTI were significantly different from those of recruits without MTI(all P＜0.001).Univariate and multivariate binary Logistic regression analysis showed that joint function screening scale and RPE scores were important influencing factors of injury in armed police recruits.The nomogram model was constructed and the receiver operating characteristic(ROC)curve was drawn,the area under the curve(AUC)of joint function screening scale was 0.752[95％confidence interval(CI):0.660-0.831)],the AUC of RPE score was 0.790(95％CI:0.712-0.874),and the AUC of the two combined tests was 0.844(95％CI:0.753-0.933),and the combined detec-tion had more advantages in the diagnostic effect.The training set and validation set were constructed,the AUC of joint function screening combined with RPE for predicting MTI in the validation set was 0.864(95％CI:0.752-0.971).The ROC curve was calibrated,and the P value of Hos-mer-Lemeshow test of the training set and the validation set was greater than 0.05.The decision curve analysis(DCA)curve was used to evaluate the risk and benefit,within the threshold range,the net benefit of the model was higher than that of the All line and None line.Conclusion Joint function screening scale combined with RPE can more effectively pre-dict the occurrence of MTI in recruits,and the method has good predictive validity and high accuracy.
