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.

Objective To study and analyze the features and pattern of the common diseases occurred among recruits of a certain naval unit during training,so as to provide reference for the prevention of diseases.Methods Medical data files in the medical corps were sorted out,and were then classified according to the types of diseases,and finally were analyzed statistically.Results During recruit training,through outpatient service,inpatient service and medical tours or calls,there were 362 cases of various diseases,accounting for 22.3% of all the recruits engaged in the recruit training.The top three diseases were:infection of the upper respiratory tract,with 128 cases,accounting for 7.88%,soft tissue injury of extremities with 68 cases,accounting for 4.18% and oral diseases with 22 cases,accounting for 1.35%.From the perspective of diseases incidence,the top 3 disease respectively accounted for 35.4%,18.8% and 6.1%,with a total incidence of 60.3% of all the diseases.Conclusions Closer attention to the weak links in disease prevention and better prevention and treatment measures against the common disease among the recruits were the surest guarantee for the reduction of incidence and improvement of training results.
